Description

[Technical field]

[0001] The present invention relates to a management device and a rental system. [Background technology]

[0002] 2. Description of the Related Art Conventionally, a network system used for real estate rental contracts is known (see, for example, Patent Document 1). For example, in the system of Patent Document 1, a real estate owner first uses his / her own communication terminal to register information about the rental property to be rented, such as an apartment room or a detached house, and desired rental conditions such as rent and tenant attributes, in a server. Then, when a prospective tenant uses his / her own communication terminal to register desired rental conditions for renting an apartment room or a detached house in the server, the server matches the desired conditions of both parties and extracts real estate that matches the conditions.

[0003] [Patent Document 1] JP 2023-82912 A Summary of the Invention [Problem to be solved by the invention]

[0004] By the way, in the case of rental properties used as residences, the tenant lives in a property that is already completed. In addition, when moving out, the property must be restored to its original state and the tenant must pay for repairs. Therefore, rental properties have problems such as restrictions on space and use, and not being able to live in the room of one's choice. In addition, the repair costs for rental properties include the cost of repairing the exterior (appearance, structure, etc.) and the cost of repairing the interior. The landlord (owner of the rental property) must bear not only the cost of repairing the exterior, but also the cost of repairing the interior that is outside the scope of the obligation to restore the property to its original condition (repair costs for aging and normal wear and tear). Even in the case of new buildings, the landlord must bear the initial construction costs. In addition, tenants are required to pay a deposit, key money, brokerage fees, etc. as initial costs of the rental contract. In other words, tenants are required to bear large initial costs when signing a rental contract. For example, a deposit is an expense that is used for repair costs (repair costs within the scope of the obligation to restore the property to its original condition), but it must be borne by the tenant regardless of whether the property is a new build or a used property.

[0005] The present invention has been made in consideration of the above circumstances, and has an object to provide rental properties that can be customized by tenants and reduce the burden on both tenants and landlords. [Means for solving the problem]

[0006] The invention described in claim 1 is, for example, as shown in Figs. 1 to 13, a management device 10 capable of communicating with a user terminal 30 used by a person who wishes to rent a rental property, A property request information acquisition means 11 for acquiring property request information from the user terminal 30; a candidate property search means 12 for searching for candidate properties based on the property request information acquired by the property request information acquisition means 11; a selection information acquisition means for acquiring, from the user terminal, property selection information related to the property selected by the renter and option selection information related to the option selected by the renter, based on the search results of the candidate property search means; an additional rent calculation means 14 for calculating an additional rent based on the option selection information acquired by the selection information acquisition means 13; The system is characterized by having an estimated rent presentation means 15 which presents the sum of the basic rent of the property corresponding to the property selection information acquired by the selection information acquisition means 13 and the additional rent calculated by the additional rent calculation means 14 as an estimated rent to the prospective renter via the user terminal 30.

[0007] According to the invention described in claim 1, when the prospective tenant becomes a tenant, the prospective tenant can add an option to the rental property, and the option can be made conditional on paying additional rent. Since the management device 10 is equipped with the estimated rent presentation means 15, the prospective tenant can select the property and the option while checking the rent including the additional rent (estimated rent). Therefore, the rental properties managed by the management device 10 include rental properties (customizable properties) to which options selected by the tenant can be added, so that the management device 10 can provide rental properties that can be customized by the tenant. In addition, in the case of rental properties where tenants can add options of their choice (customizable properties), the cost of repairs to the interior (repair costs inside the property) is borne by the tenant through additional rent, reducing the burden on the landlord. In addition, in rental properties where tenants can add their own options (customizable properties), the tenant does not have to pay repair costs for the next tenant (repair costs within the scope of the obligation to restore the property to its original condition). In other words, there is no need to pay a deposit, which reduces the burden on the tenant.

[0008] The invention described in claim 2 is, for example, as shown in Figs. 5 to 11, in the management device 10 described in claim 1, The option is characterized in that at least one of the following can be selected: the equipment and decoration inside the property, the layout, and the skeleton state.

[0009] According to the invention described in claim 2, when the prospective tenant becomes a tenant, the prospective tenant can add options to the rental property, and by adding options, the prospective tenant can customize the facilities and decorations inside the property, as well as the layout. Therefore, problems such as restrictions on space and use, and not being able to live in a room of one's choice can be effectively solved.

[0010] The invention described in claim 3 is, for example, as shown in Figs. 7 to 9, in the management device 10 described in claim 1, The option is characterized in that DIY can be selected.

[0011] According to the invention described in claim 3, when the prospective tenant becomes a tenant, the prospective tenant can add options to the rental property, and by adding the options, the prospective tenant can DIY the equipment and decorations inside the property, and DIY the layout of the property. Therefore, problems such as restrictions on space and use, and not being able to live in a room of one's choice can be effectively solved.

[0012] The invention described in claim 4 is, for example, as shown in Figs. 7 to 9, in the management device 10 described in claim 3, A DIY support image is presented to the prospective renter via the user terminal 30.

[0013] According to the invention described in claim 4, prospective renters can select DIY as an option after understanding how to do it, etc. Therefore, it is possible to suppress hesitation to do DIY for reasons such as not knowing how to do it, and it is possible to promote the selection of DIY as an option.

[0014] The invention described in claim 5 is, for example, as shown in FIG. 10, in the management device 10 described in claim 1, A proposed furniture layout for the property selected by the prospective tenant is presented to the prospective tenant via the user terminal 30.

[0015] According to the invention described in claim 5, prospective tenants can select properties and options while checking the furniture arrangement layout.

[0016] The invention as recited in claim 6 is, for example, as shown in Figs. 6 to 11, in the management device 10 as recited in claim 1, A feature of the system is that each option available for the property selected by the prospective tenant is presented to the prospective tenant via the user terminal 30, together with the individual additional rent that would be incurred if the option is adopted.

[0017] According to the invention described in claim 6, prospective tenants can select options while checking the individual additional rents.

[0018] The invention described in claim 7 is, for example, as shown in FIG. 5, in the management device 10 described in claim 1, The method is characterized in that information regarding the evaluation of the property selected by the rent applicant is presented to the rent applicant via the user terminal 30.

[0019] According to the invention described in claim 7, prospective tenants can determine, before renting a property, based on information regarding the property's evaluation, whether there are any factors that would prevent them from living there for a long period of time, thereby encouraging renters to add options by renting rental properties that allow options to be added (customizable properties).

[0020] The invention described in claim 8 is, for example, as shown in Figs. 1 to 13, a rental system 1, A management device 10 according to claim 1; The user terminal 30 is also provided.

[0021] According to the invention described in claim 8, when the prospective tenant becomes a tenant, the prospective tenant can add an option to the rental property, and the option can be made conditional on paying additional rent. Since the management device 10 is equipped with the estimated rent presentation means 15, the prospective tenant can select a property and an option while checking the rent including the additional rent (estimated rent). Therefore, the rental properties handled by rental system 1 include rental properties (customizable properties) that can be fitted with options selected by the tenant, so rental system 1 can provide rental properties that can be customized by the tenant. In addition, in the case of rental properties where tenants can add options of their choice (customizable properties), the cost of repairs to the interior (repair costs inside the property) is borne by the tenant through additional rent, reducing the burden on the landlord. In addition, in rental properties where tenants can add their own options (customizable properties), the tenant does not have to pay repair costs for the next tenant (repair costs within the scope of the obligation to restore the property to its original condition). In other words, there is no need to pay a deposit, which reduces the burden on the tenant. Effect of the Invention

[0022] According to the present invention, it is possible to provide rental properties that can be customized by tenants and reduce the burden on both tenants and landlords. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0024] Hereinafter, the embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are subject to various technically preferable limitations for carrying out the present invention, but the technical scope of the present invention is not limited to the following embodiments and illustrated examples. In the following embodiments and illustrated examples, "XX" is one or more arbitrary letters and numbers. For example, in the case of "XX yen", "XX yen" does not represent a two-digit amount (10 yen or more and 99 yen or less), but represents an amount of one or more digits (1 yen or more (no upper limit), which may include 0 yen (free)). In the illustrated examples, the multiple "XX yen" may represent the same amount or different amounts.

[0025] [First embodiment] <Rental System> FIG. 1 is a block diagram showing an example of the configuration of a rental system 1 in the first embodiment. The rental system 1 is a system that provides property information on candidate properties (rental properties that meet the conditions of a prospective tenant) to a prospective tenant (user) who is looking for a rental property to use as a residence.

[0026] The rental properties handled by the rental system 1 include rental properties where the tenant can customize the interior, floor plan, etc. (hereinafter referred to as "customizable properties"). Furthermore, the rental system 1 allows the tenant to select options (interior, floor plan, etc.) to be added to the customizable property before moving in, and allows the tenant to pay the cost of the option in installments on top of the rent. Note that the range of options available for customizable properties (options that the tenant can select) is determined in advance by the lessor, etc. In other words, customizable properties are premised on the tenant customizing the interior and layout, and do not need to be restored to their original state for the next tenant. Therefore, customizable properties do not require the cost of restoring the property to its original state (deposit), and instead the tenant is responsible for the cost of customizing the property to their own liking (optional costs, etc.), so tenants can feel satisfied with the costs of the rental contract. The option fee is amortized over several years (two years in this embodiment). In the case of mid-term termination (termination of the rental contract before full payment), the remaining amount is paid in a lump sum by the lessee at the time of termination, etc., or by the guarantor company.

[0027] As shown in FIG. 1, the rental system 1 includes a management device 10 and a database 20 that constitute a semi-rental bank, and a user terminal 30 that is used by a person who wishes to rent (a user). The management device 10, the database 20, and the user terminal 30 are communicatively connected to each other via a communication network N. The communication network N is not particularly limited, but may be, for example, the Internet, a LAN (Local Area Network), a WAN (Wide Area Network), etc.

[0028] The user terminal 30 is composed of a computer such as a PC, a smartphone, a tablet, etc., and is owned and used by the person who wishes to rent. In this embodiment, a smartphone, which is a portable information terminal, is used.

[0029] The database 20 stores various information necessary for the rental system 1. Specifically, for example, property information on rental properties provided by lessors (property owners and real estate agents) is stored for each property in the database 20. In other words, the property owners and real estate agents are able to register property information on rental properties in the database 20. The property information for rental properties stored in database 20 includes various information such as the area in which the building including the rental property is located, the nearest facilities such as the nearest station, the distance from each nearest facility, the exclusive area, layout type, floor plan (floor plan showing past and current layouts), age of the property, rent (basic rent), management fees and common area fees, facilities and features, related images, information on common areas, option information, and home evaluation information.

[0030] <Management device> The management device 10 includes a processor, a display unit, an input unit, a communication unit, and the like. The arithmetic processing device of the management device 10 is composed of a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), etc., and controls the processing operations of each part in the rental system 1 in an integrated manner. Specifically, a program is stored in the arithmetic processing unit of the management device 10. The arithmetic processing unit executes the program to realize the functions of the management device 10, that is, the means 11 to 15 included in the management device 10 shown in FIG.

[0031] The management device 10 includes a property preference information acquiring means 11 for acquiring property preference information from the user terminal 30 . The management device 10 also includes a candidate property search means 12 that searches for candidate properties based on the property desire information acquired by the property desire information acquisition means 11 . The management device 10 also has a selection information acquisition means 13 that acquires, from the user terminal 30, property selection information regarding the property selected by the renter and option selection information regarding the option selected by the renter, based on the search results of the candidate property search means 12. The management device 10 also includes an additional rent calculation means 14 that calculates an additional rent based on the option selection information acquired by the selection information acquisition means 13. The management device 10 also includes an estimated rent presentation means 15 which presents the sum of the basic rent of the property corresponding to the property selection information acquired by the selection information acquisition means 13 and the additional rent calculated by the additional rent calculation means 14 as an estimated rent to the prospective renter via the user terminal 30.

[0032] <Operation flow> FIG. 2 is a flowchart showing an example of the operation of the rental system 1 in the first embodiment. First, the user terminal 30 logs in to the management device 10 (step S1). Specifically, for example, application programs such as an Internet browser and a browsing program are installed in the user terminal 30. The user terminal 30 executes the application program to access the management device 10 via the communication network N and logs in to the management device 10 based on a user ID (identifier) ​​and a password.

[0033] When the user terminal 30 logs in to the management device 10, the management device 10 acquires property preference information from the user terminal 30 by the property preference information acquisition means 11 (steps S2 to S3). Specifically, the property desired information acquiring means 11 transmits data for displaying the property desired information input screen G1 to the user terminal 30 via the communication network N. As a result, the property desired information input screen G1 is displayed on the display unit of the user terminal 30 (step S2).

[0034] FIG. 3 is a diagram showing an example of the property desired information input screen G1. In the property desired information input screen G1, the area, distance from the nearest station, exclusive area, and layout type can be input as property desired information (conditions for a rental property you would like to live in). Note that the property desired information is not limited to the information shown in FIG. 3, and may include other information such as the age of the building and rent. In other words, the property desired information may be information equivalent to the information entered when searching for a rental property on a general real estate information site, for example.

[0035] When the renter has completed inputting the desired property information, he / she taps the registration button B11 on the desired property information input screen G1. When the registration button B11 is tapped, the user terminal 30 transmits the input desired property information together with the user ID and the like to the management device 10 via the communication network N (step S3). In this manner, the desired property information acquisition means 11 acquires the desired property information from the user terminal 30.

[0036] Next, the management device 10 searches for candidate properties using the candidate property search means 12 based on the property desire information acquired by the property desire information acquisition means 11 (step S4). Specifically, the candidate property search means 12 extracts property information of candidate properties (properties that match the property desire information acquired by the property desire information acquisition means 11) from a plurality of property information stored in the database 20.

[0037] Next, the management device 10, through the selection information acquisition means 13, acquires from the user terminal 30 property selection information regarding the property selected by the renter and option selection information regarding the option selected by the renter based on the search results of the candidate property search means 12 (steps S5 to S10). Specifically, the selection information acquisition means 13 transmits data for displaying the candidate property presentation screen G2 to the user terminal 30 via the communication network N. As a result, the candidate property presentation screen G2 is displayed on the display unit of the user terminal 30 (step S5).

[0038] FIG. 4 is a diagram showing an example of the candidate property presentation screen G2. On the candidate property presentation screen G2, as the search results of the candidate property search means 12, a part of the property information extracted by the candidate property search means 12 in step S4 is displayed for each candidate property. If the prospective renter finds a property that the renter is interested in among the candidate properties displayed on the candidate property display screen G2, the renter selects the property. Specifically, the renter taps the details button of the property that the renter is interested in among the details buttons B21, B22, B23, B24, B25, ... on the candidate property display screen G2.

[0039] When any of the details buttons B21, B22, B23, B24, B25, etc. is tapped, the user terminal 30 transmits property selection information (e.g., property ID) regarding the property selected by the prospective renter (the candidate property for which the details button was tapped) together with the user ID, etc., to the management device 10 via the communications network N (step S6). When the communication unit of the management device 10 receives the property selection information, the selection information acquisition means 13 extracts property information corresponding to the property selection information from the multiple property information stored in the database 20 (or from the property information extracted by the candidate property search means 12 in step S4). Then, the selection information acquisition means 13 transmits data for displaying a property information presentation screen G3 to the user terminal 30 via the communication network N. As a result, the property information presentation screen G3 is displayed on the display unit of the user terminal 30 (step S7).

[0040] Fig. 5 is a diagram showing an example of the property information presentation screen G3. Fig. 5 shows an example of the property information presentation screen G3 that is displayed when the details button B22 on the candidate property presentation screen G2 is tapped, that is, when the property selected by the prospective renter is "Property B." The property information display screen G3 displays more detailed information about the property selected by the prospective renter (here, "Property B") than the candidate property display screen G2. Specifically, the property information display screen G3 displays the nearest station, distance from the nearest station, exclusive area, and layout type, as well as information about the common areas, basic rent, options, and home evaluation information. "Property B" is a customizable property, and the property information display screen G3 for customizable properties displays "options" and "home evaluation information."

[0041] The property information displayed on the property information presentation screen G3 is not limited to the information shown in Fig. 5, and may include other information, such as the nearest facilities other than the nearest station, the distance from the nearest facilities, the age of the building, the facilities and features, related images such as interior photos and surrounding photos, floor plans, etc. In other words, the property information displayed on the property information presentation screen G3 other than "options" and "housing evaluation information" may be equivalent to information displayed as a search result for rental properties on a general real estate information site, for example. Below, we will explain the "options" and "home appraisal information" that are not displayed on general real estate information sites among the property information displayed on the property information presentation screen G3. As the other information is publicly known, we will not explain it here.

[0042] On the property information presentation screen G3 shown in FIG. 5, as "options", an option related to "interior", an option related to "layout", and an option related to "skeleton" can be selected. The property information stored in the database 20 includes option information, which includes the types of options that can be adopted for the corresponding property. If the property selected by the prospective renter is a property that prohibits interior customization (for example, a property where interior customization is prohibited by the lessor), the property information for that property stored in the database 20 does not include "interior" as a type of option that can be adopted. Therefore, the "interior" column is not displayed on the property information presentation screen G3 for that property, and options related to "interior" cannot be selected as "options". The same applies to "layout" and "skeleton".

[0043] If a prospective renter finds an option that interests him or her among the options displayed on the property information display screen G3, he or she selects that option. Specifically, if a prospective renter is interested in interior options, he or she taps the Details button B31 in the "Interior" field on the property information presentation screen G3. In the "Interior" field, the renter can select whether to "Change" the interior (add interior options) or "Not Change" the interior (not add interior options), and the Details button B31 can be operated only when "Change" is selected. In the example shown in FIG. 5, "Change" is selected.

[0044] When the details button B31 is tapped, the user terminal 30 notifies the management device 10 of the type of option selected by the renter (here, "interior") together with the user ID and the like via the communication network N (step S8). When the communication unit of the management device 10 receives the notification, the selection information acquisition means 13 transmits data for displaying the interior option selection information input screen G4 to the user terminal 30 via the communication network N. As a result, the interior option selection information input screen G4 is displayed on the display unit of the user terminal 30 (step S9). The interior option selection information input screen G4 will be described in detail later.

[0045] Furthermore, if the prospective renter is interested in options related to the floor plan, he or she taps the Details button B32 in the "Floor plan" field on the property information presentation screen G3. In the "Floor plan" field, the renter can select whether to "Change" the floor plan (add options related to the floor plan) or "Not Change" the floor plan (not add options related to the floor plan), and the Details button B32 can be operated only when "Change" is selected. In the example shown in FIG. 5, "Change" is selected.

[0046] When the details button B32 is tapped, the user terminal 30 notifies the management device 10 of the type of option selected by the renter (here, "floor plan") together with the user ID and the like via the communication network N (step S8). When the communication unit of the management device 10 receives the notification, the selection information acquisition means 13 transmits data for displaying the floor plan option selection information input screen G5 to the user terminal 30 via the communication network N. As a result, the floor plan option selection information input screen G5 is displayed on the display unit of the user terminal 30 (step S9). The floor plan option selection information input screen G5 will be described in detail later.

[0047] Furthermore, if the prospective renter is interested in options related to the skeleton, i.e., interested in skeleton delivery (handover in skeleton state), he / she taps the Details button B33 in the "Skeleton" field on the property information presentation screen G3. In the "Skeleton" field, it is possible to select whether to "yes" to skeleton delivery (whether to add skeleton options) or "no" to skeleton delivery (whether to not add skeleton options), and the Details button B33 can be operated only when "yes" is selected. In the example shown in FIG. 5, "no" is selected. For example, when the prospective renter wishes to customize the interior (equipment and decoration inside the property) and the layout (installation, removal, movement of partition walls, etc.) by himself, he selects "Skeleton" as an "Option". In other words, when the prospective renter wishes to remodel (renovate) the interior and layout by himself, he selects "Yes" in the "Skeleton" field on the property information presentation screen G3. In this embodiment, "do it yourself" includes not only the prospective renter doing it himself, but also the prospective renter requesting someone (such as an interior decorator) to do it.

[0048] When the details button B33 is tapped, the user terminal 30 notifies the management device 10 of the type of option selected by the renter (here, "skeleton") together with the user ID and the like via the communication network N (step S8). When the communication unit of the management device 10 receives the notification, the selection information acquisition means 13 transmits data for displaying the skeleton option selection information input screen G6 to the user terminal 30 via the communication network N. As a result, the skeleton option selection information input screen G6 is displayed on the display unit of the user terminal 30 (step S9). The skeleton option selection information input screen G6 will be described in detail later. The "Housing Evaluation Information" displayed on the property information display screen G3 will also be described in detail later.

[0049] The option selection information input screens G4, G5, and G6 allow the user to input option selection information regarding the options selected by the renter. When the renter has finished inputting the option selection information, he / she taps the registration button B35 on the property information presentation screen G3. When the registration button B35 is tapped, the user terminal 30 transmits the input option selection information together with the user ID and the like to the management device 10 via the communications network N (step S10). In this way, the selection information acquisition means 13 acquires, based on the search results of the candidate property search means 12, property selection information related to the property selected by the renter and option selection information related to the option selected by the renter from the user terminal 30.

[0050] Next, the management device 10 calculates the additional rent (total additional rent) by the additional rent calculation means 14 based on the option selection information acquired by the selection information acquisition means 13 (step S11). In this embodiment, the total additional rent is the sum of the total estimated costs (estimated option costs) required if each option selected by the prospective tenant is adopted, divided by a specified number of installments (e.g., 24 installments), and the installment fee, but is not limited to this.

[0051] Next, the management device 10 presents the sum of the base rent of the property corresponding to the property selection information acquired by the selection information acquisition means 13 and the additional rent calculated by the additional rent calculation means 14 as an estimated rent to the prospective renter via the user terminal 30 (step S12). Specifically, the estimated rent presentation means 15 extracts property information corresponding to the property selection information transmitted in step S6 from among the multiple property information stored in the database 20 (or from among the property information extracted by the candidate property search means 12 in step S4), and calculates the sum of the basic rent included in the extracted property information and the additional rent calculated by the additional rent calculation means 14. The estimated rent presentation means 15 then transmits data for displaying an estimated rent presentation screen to the user terminal 30 via the communication network N. As a result, the estimated rent presentation screen is displayed on the display unit of the user terminal 30 (step S12), and the estimated rent calculated by the estimated rent presentation means 15 (the sum of the basic rent and the additional rent) is presented to the prospective renter. The basic rent is stored in database 20 (it is included in the optional information of the property information stored in database 20). The basic rent may be, for example, input in advance by the lessor (property owner or real estate agent) and registered in database 20, or it may be automatically input in advance based on market prices and registered in database 20. In addition, the basic rent registered (stored) in database 20 may be changeable by the lessor, for example, within an amendable range.

[0052] <Interior option selection information input screen> 6 is a diagram showing an example of the interior option selection information input screen G4. The interior option selection information input screen G4 is displayed when "Change" is selected in the "Interior" field on the property information presentation screen G3 (FIG. 5) and the Details button B31 is tapped. On the interior option selection information input screen G4 shown in FIG. 6, "wallpaper," "intercom," and "telework space" can be selected as interior options.

[0053] The property information stored in the database 20 includes option information, which includes the types of interior decoration that can be adopted for the corresponding property. If the property selected by the prospective renter is a property that prohibits wallpaper customization (for example, a property where wallpaper customization is prohibited by the lessor), the property information for that property stored in the database 20 does not include "wallpaper" as a type of interior decoration that can be adopted. Therefore, the "wallpaper" field is not displayed on the interior decoration option selection information input screen G4 for that property, and options related to "wallpaper" cannot be selected as interior decoration options. The same applies to "intercom" and "telework space." Note that the interior options are not limited to those shown in FIG. 6, but may include other options such as flooring, fixtures, storage, toilets, kitchens, and bathrooms.

[0054] On the interior option selection information input screen G4 shown in FIG. 6, the currently selected wallpaper type is “Wallpaper A,” the currently selected intercom type is “With monitor,” and the currently selected telework space type is “With reinforced base.” When the decision button B44 on the interior option selection information input screen G4 is tapped, the user terminal 30 stores the selected wallpaper type, the selected intercom type, and the selected telework space type as interior selection information, and returns to the property information presentation screen G3 (FIG. 5). The interior selection information stored here is transmitted to the management device 10 as part of the option selection information when the registration button B35 is tapped with "Change" selected in the "Interior" field on the property information presentation screen G3 (step S10). On the other hand, when the registration button B35 is tapped with "Do not change" selected in the "Interior" field, even if the interior selection information has been stored, default information ("Do not customize" described later) is transmitted to the management device 10 as part of the option selection information (step S10) instead of the stored interior selection information.

[0055] In the illustrated examples (e.g., Figs. 6 to 11), "+ XX yen / month" indicates the additional rent (individual additional rent) that occurs when the corresponding option is adopted. The total amount of the additional rent (individual additional rent) that occurs when the option selected by the prospective renter is adopted is the additional rent (total additional rent) calculated by the additional rent calculation means 14. In this embodiment, the individual additional rent is, for example, the sum of the estimated cost (estimated option cost) required if the corresponding option is adopted divided by a specified number of installments (for example, 24 installments) and the installment fee, but is not limited to this. The individual rent surcharge is stored in the database 20 (for example, it is included in the optional information of the property information stored in the database 20). The individual rent surcharge may be input in advance by the lessor (property owner or real estate agent) and registered in the database 20, for example, or it may be automatically input in advance based on the market price or the like and registered in the database 20. In addition, the individual rent surcharge registered (stored) in the database 20 may be changeable by the lessor, for example, within a modifiable range.

[0056] 〔wallpaper〕 6, the type of wallpaper being selected is "Wallpaper A," but the type of wallpaper being selected can be changed by tapping the change button B41 in the "Wallpaper" field on the interior design option selection information input screen G4. Specifically, for example, when the change button B41 is tapped, the wallpaper change screen G41 is displayed on the display unit of the user terminal 30.

[0057] FIG. 7 is a diagram showing an example of the wallpaper change screen G41. The wallpaper change screen G41 allows the user to change the type of wallpaper currently selected. Furthermore, the wallpaper change screen G41 allows the user to select "Do not customize" if no wallpaper options are required, and allows the user to select "DIY (Do It Yourself)" if the prospective tenant will prepare and apply the wallpaper themselves. The wallpaper change screen G41 has a DIY support button B411, and by tapping this DIY support button B411, a DIY support image for the wallpaper (for example, a video or photo that serves as a model for how to apply wallpaper by DIY) can be viewed. This allows prospective tenants to select "DIY" after understanding how to do DIY.

[0058] By tapping on the details buttons B412 to B418 on the wallpaper change screen G41, detailed information (photo, material, function, etc.) about the corresponding wallpaper can be viewed. Specifically, for example, when the details button B415 is tapped, detailed information about the wallpaper D is displayed on the display unit of the user terminal 30.

[0059] In addition, by tapping the decision button B419 on the wallpaper change screen G41, the user can return to the interior option selection information input screen G4 reflecting the type of wallpaper being selected. Specifically, for example, when the decision button B419 is tapped while "Wallpaper A" is selected as shown in Fig. 7, the interior option selection information input screen G4 as shown in Fig. 6 is displayed on the display unit of the user terminal 30, that is, the interior option selection information input screen G4 with "Wallpaper A" written in the "Wallpaper" field. In this embodiment, the default for the selected wallpaper type is "not customized", but this is not limited to this.

[0060] The property information stored in the database 20 includes option information, and the option information includes the types of wallpaper that can be used in the corresponding property. The wallpaper change screen G41 lists the types of wallpaper that can be used. That is, the wallpaper change screen G41 shown in Figure 7 is the wallpaper change screen G41 for property B, and this wallpaper change screen G41 lists the types of wallpaper that can be used (no customization, DIY, wallpapers A to G) included in the property information for property B stored in database 20.

[0061] The additional rent (individual additional rent) for "Wallpaper A" on the wallpaper change screen G41 is an amount based on the estimated cost of preparing and pasting wallpaper A by a person requested by the lessor (property owner or real estate agent). If the current wallpaper needs to be removed in order to put up new wallpaper, the cost of removing it is also included. The same applies to the additional rent (individual additional rent) for "Wallpaper B" to "Wallpaper G."

[0062] The "DIY" surcharge (individual surcharge) on the wallpaper change screen G41 is based on the estimated cost of removing the current wallpaper. Therefore, if the property selected by the prospective tenant does not have wallpaper (for example, a newly built property where wallpapering has not yet begun, or a skeleton house), the "DIY" surcharge will not be incurred. On the wallpaper change screen G41, you may select "DIY" from two options: "DIY" where you prepare and paste the wallpaper yourself, and "DIY" where you not only prepare and paste the wallpaper but also remove the wallpaper that is currently pasted. In the case of "DIY" where you also remove the wallpaper yourself, no additional rent will be charged.

[0063] [Intercom] 6, the selected type of intercom is "with monitor," but the selected type of intercom can be changed by tapping the change button B42 in the "intercom" field on the interior option selection information input screen G4. Specifically, for example, when the change button B42 is tapped, the intercom change screen G42 is displayed on the display unit of the user terminal 30.

[0064] FIG. 8 is a diagram showing an example of the intercom change screen G42. The intercom change screen G42 allows the user to change the type of intercom currently selected. Furthermore, the intercom change screen G42 allows the user to select "Do not customize" if no intercom options are required, and allows the user to select "DIY" if the user is to prepare and install the intercom by himself / herself. The intercom change screen G42 has a DIY support button B421, and by tapping this DIY support button B421, it is possible to view DIY support images for the intercom (for example, videos and photos that serve as examples for installing an intercom by DIY). This allows prospective tenants to select "DIY" after understanding how to do it.

[0065] By tapping the details buttons B422 and B423 on the intercom change screen G42, detailed information (photos, functions, etc.) regarding the corresponding intercom can be viewed. Specifically, for example, when the details button B423 is tapped, detailed information about the monitor-less intercom is displayed on the display unit of the user terminal 30.

[0066] Furthermore, by tapping the decision button B424 on the intercom change screen G42, the user can return to the interior option selection information input screen G4 reflecting the selected intercom type. Specifically, for example, when the decision button B424 is tapped with "With monitor" selected as shown in Fig. 8, the interior option selection information input screen G4 as shown in Fig. 6 is displayed on the display unit of the user terminal 30, that is, the interior option selection information input screen G4 with "With monitor" written in the "Intercom" field. In this embodiment, the default for the selected intercom type is "not customized," but this is not limited to this.

[0067] The property information stored in the database 20 includes option information, and the option information includes the types of intercoms that can be used in the corresponding property. The intercom change screen G42 lists the types of intercoms that can be used. That is, the intercom change screen G42 shown in Figure 8 is the intercom change screen G42 for property B, and this intercom change screen G42 lists the types of intercoms that can be used (not customized, DIY, with monitor, without monitor) included in the property information for property B stored in database 20.

[0068] The "monitored" rent surcharge (individual surcharge) on the intercom change screen G42 is based on the estimated cost of preparing and installing a monitored intercom by a party requested by the lessor (property owner or real estate agent). If the currently installed intercom needs to be removed in order to install a new one, the cost of removing it is also included. The same applies to the "non-monitored" rent surcharge (individual surcharge).

[0069] The "DIY" surcharge (individual surcharge) on the intercom change screen G42 is based on the estimated cost of removing the currently installed intercom. Therefore, if the property selected by the prospective tenant is one that does not have an intercom installed (for example, a newly built property where the work to install an intercom has not yet begun, a skeleton house, or a newly built or used property without an intercom), the "DIY" surcharge will not be incurred. In the intercom change screen G42, you may select either "DIY" where you prepare and install the intercom yourself, or "DIY" where you not only prepare and install the intercom but also remove the currently installed intercom yourself. In the case of DIY where you also remove the intercom yourself, no additional rent will be charged.

[0070] [Telework space] 6, the type of telework space being selected is "with reinforced base" on the interior option selection information input screen G4, but the type of the selected telework space can be changed by tapping the change button B43 in the "telework space" field on the interior option selection information input screen G4. Specifically, for example, when the change button B43 is tapped, the telework space change screen G43 is displayed on the display unit of the user terminal 30.

[0071] FIG. 9 is a diagram showing an example of the teleworkspace change screen G43. The teleworkspace change screen G43 allows the user to change the type of the selected teleworkspace. Specifically, the user can select a teleworkspace with "reinforcement base" (a teleworkspace whose walls are reinforced with a reinforcing base) or a teleworkspace without "reinforcement base" (a teleworkspace whose walls are not reinforced with a reinforcing base).

[0072] Furthermore, on the teleworkspace modification screen G43, "Do not customize" can be selected if no teleworkspace options are to be added, or "DIY" can be selected if the prospective tenant will prepare and set up the materials for the teleworkspace themselves. The teleworkspace change screen G43 has a DIY support button B431, and by tapping this DIY support button B431, it is possible to view DIY support images for the teleworkspace (for example, videos and photos that serve as examples for setting up a teleworkspace by DIY). This allows prospective tenants to select "DIY" after understanding how to do DIY.

[0073] By tapping the decision button B432 on the teleworkspace change screen G43, the user can return to the interior option selection information input screen G4 reflecting the type of teleworkspace being selected. Specifically, for example, when the decision button B432 is tapped with "reinforced base" selected as shown in Fig. 9, the interior option selection information input screen G4 as shown in Fig. 6 is displayed on the display unit of the user terminal 30, that is, the interior option selection information input screen G4 with "reinforced base" written in the "teleworkspace" field. In this embodiment, the default for the type of telework space being selected is "not customized", but this is not limited to this.

[0074] The property information stored in the database 20 includes option information, and the option information includes the types of telework spaces that can be used in the corresponding property. The types of telework spaces that can be used are listed on the telework space change screen G43. That is, the teleworkspace change screen G43 shown in Figure 9 is the teleworkspace change screen G43 for property B, and this teleworkspace change screen G43 lists the types of teleworkspace that can be adopted (not customized, DIY, with reinforced base, without reinforced base) included in the property information for property B stored in database 20.

[0075] The rent surcharge (individual surcharge) for "with reinforced base" on the teleworkspace change screen G43 is based on the estimated cost of a party requested by the lessor (property owner or real estate agent) to prepare and install materials for a teleworkspace with walls reinforced with a reinforcing base. If the currently installed teleworkspace needs to be removed in order to install a new teleworkspace, the cost of removal is also included. The same applies to the rent surcharge (individual surcharge) for "without reinforced base."

[0076] The "DIY" rent surcharge (individual rent surcharge) on the teleworkspace change screen G43 is an amount based on the estimated cost of removing the currently installed teleworkspace. Therefore, if the property selected by the prospective tenant is a property that does not have a teleworkspace installed (for example, a newly built property where the work to install a teleworkspace has not yet begun, a skeleton house, or a newly built or used property without a teleworkspace), the "DIY" rent surcharge will not be incurred. The teleworkspace change screen G43 may allow the user to select, as "DIY," either a DIY in which the user prepares and installs the materials for the teleworkspace by himself, or a DIY in which the user not only prepares and installs the materials for the teleworkspace, but also removes the currently installed teleworkspace by himself. In the case of a DIY in which the user also removes the teleworkspace by himself, no additional rent will be charged.

[0077] 《Floor plan option selection information input screen》 10 is a diagram showing an example of the floor plan option selection information input screen G5. The floor plan option selection information input screen G5 is displayed when "Change" is selected in the "Floor Plan" field on the property information presentation screen G3 (FIG. 5) and the Details button B32 is tapped. The screen G5 for inputting floor plan option selection information displays a floor plan showing the current floor plan, a floor plan showing the selected floor plan, and the additional rent (individual additional rent) that will be incurred if the selected floor plan is adopted. If the property selected by the prospective tenant is a property without a floor plan (for example, a newly built property where partition work has not yet begun, or a skeleton house), for example, a diagram showing only the skeleton is displayed as the floor plan showing the current floor plan.

[0078] In the floor plan option selection information input screen G5 shown in Fig. 10, the type of floor plan being selected is "Floor plan F", but the type of the selected floor plan can be changed by tapping the change button B53 in the "Selected" field on the floor plan option selection information input screen G5. Specifically, for example, when the change button B53 is tapped, a different floor plan is displayed in the "Selected" field.

[0079] The property information stored in the database 20 includes option information, and the option information includes types of floor plans that can be adopted for the corresponding property. In the "Selected" field of the floor plan option selection information input screen G5, one of the types of floor plans that can be adopted is displayed. That is, the floor plan option selection information input screen G5 shown in FIG. 10 is the floor plan option selection information input screen G5 for property B, and the “Selecting” column of this floor plan option selection information input screen G5 sequentially displays the types of floor plans that can be used (not customized (no floor plan options), floor plans A, B, C, etc.) included in the property information of property B stored in the database 20 each time the change button B53 is tapped. In this embodiment, the default for the type of floor plan being selected is "not customized," but this is not limited to this.

[0080] By tapping the furniture layout plan button B51 in the "Current" column on the floor plan option selection information input screen G5, a furniture arrangement layout plan for the current floor plan can be viewed. Specifically, for example, when the furniture layout plan button B51 is tapped, a furniture arrangement layout diagram is superimposed on the floor plan in the "Current" column (a floor plan showing the current floor plan). The furniture layout plan button B51 is displayed, for example, when a furniture arrangement layout plan is stored in the database 20 together with the current floor plan.

[0081] In addition, by tapping the furniture layout plan button B52 in the "selected" column on the floor plan option selection information input screen G5, a furniture arrangement layout plan for the selected floor plan can be viewed. Specifically, for example, when the furniture layout plan button B52 is tapped, a furniture arrangement layout diagram is superimposed on the floor plan in the "selected" column (floor plan showing the selected floor plan). The furniture layout plan button B52 is displayed, for example, when furniture arrangement layout plans are stored in the database 20 together with available floor plans.

[0082] When the decision button B54 on the floor plan option selection information input screen G5 is tapped, the user terminal 30 stores the type of floor plan being selected as floor plan selection information, and returns to the property information presentation screen G3 (FIG. 5). When the registration button B35 is tapped with "Change" selected in the "Floor Plan" field on the property information presentation screen G3, the floor plan selection information stored here is transmitted to the management device 10 as part of the option selection information (step S10). On the other hand, when the registration button B35 is tapped with "Do not change" selected in the "Floor Plan" field, even if the floor plan selection information has been stored, default information ("Do not customize") is transmitted to the management device 10 as part of the option selection information (step S10), instead of the stored floor plan selection information.

[0083] <<Skeleton option selection information input screen>> 11 is a diagram showing an example of the skeleton option selection information input screen G6. The skeleton option selection information input screen G6 is displayed when "Yes" is selected in the "Skeleton" field on the property information presentation screen G3 (FIG. 5) and the details button B33 is tapped. On the skeleton option selection information input screen G6 shown in Fig. 11, you can select between "Skeleton except for water features," which will hand over everything except the water features in a skeleton state, and "Entire skeleton," which will hand over the whole thing including the water features in a skeleton state. Furthermore, on the skeleton option selection information input screen G6 shown in Fig. 11, you can also select "Do not customize," which will hand over the thing without being in a skeleton state, that is, to not add any options related to the skeleton. In this embodiment, the default for the type of skeleton being selected is "not customized," but this is not limited to this.

[0084] The property information stored in the database 20 includes option information, and the option information includes types of skeletons that can be adopted for the corresponding property. The skeleton option selection information input screen G6 lists the types of skeletons that can be adopted. That is, the option selection information input screen G6 for skeleton shown in Figure 11 is the option selection information input screen G6 for skeleton of property B, and this option selection information input screen G6 for skeleton lists the types of skeletons that can be adopted (no customization, skeleton other than plumbing, entire skeleton) included in the property information of property B stored in database 20.

[0085] Therefore, if the property selected by the prospective renter is one that is prohibited from being handed over in a fully skeletonized state (for example, a property that is prohibited by the lessor from being fully skeletonized), "full skeleton" is not included as an available skeleton type in the property information for that property stored in database 20. Therefore, the "full skeleton" field is not displayed on skeleton option selection information input screen G6 for that property, and "full skeleton" cannot be selected as an option for the skeleton.

[0086] Furthermore, if the property selected by the prospective renter is, for example, a property that does not have plumbing facilities installed (for example, a newly built property where work to install plumbing facilities has not yet begun, or a skeleton house), the property information for that property stored in database 20 does not include "skeleton other than plumbing" as an available skeleton type. Therefore, the "skeleton other than plumbing" field is not displayed on the skeleton option selection information input screen G6 for that property, and "skeleton other than plumbing" cannot be selected as an option for the skeleton.

[0087] The rent surcharge (individual rent surcharge) for "Skeleton excluding plumbing" on the option selection information input screen G6 for skeleton is an amount based on the estimated cost required to remove the equipment (excluding plumbing), decorations, partitions, etc. currently installed inside the property. In addition, the "whole skeleton" additional rent (individual additional rent) on the skeleton option selection information input screen G6 is an amount based on the estimated cost required to remove the currently installed equipment (including plumbing), decorations, partitions, etc. inside the property. Therefore, if the property selected by the prospective tenant is a property without interior decoration (equipment and decoration) or partitions (for example, a newly built property where partition and interior construction work has not yet begun, or a skeleton house), the "whole skeleton" additional rent will not be incurred.

[0088] In the skeleton option selection information input screen G6 shown in FIG. 11, the type of skeleton being selected is "whole skeleton." When the decision button B61 on the skeleton option selection information input screen G6 is tapped, the user terminal 30 stores the type of skeleton being selected as skeleton selection information, and returns to the property information presentation screen G3 (FIG. 5). The skeleton selection information stored here is transmitted to the management device 10 as part of the option selection information when the registration button B35 is tapped with "Yes" selected in the "Skeleton" field on the property information presentation screen G3 (step S10). On the other hand, when the registration button B35 is tapped with "No" selected in the "Skeleton" field, even if skeleton selection information has been stored, default information ("Do not customize") is transmitted to the management device 10 as part of the option selection information (step S10), instead of the stored skeleton selection information.

[0089] 《Housing evaluation information》 When the view button B34 in the “Housing Appraisal Information” field on the property information presentation screen G3 (Figure 5) is tapped, the display unit of the user terminal 30 displays the housing appraisal information of the property selected by the prospective renter (here, “Property B”). The housing evaluation information includes noise information that evaluates noise heard within and around the property, surrounding environment information that evaluates the surrounding environment of the property, etc. The housing evaluation information is input, for example, by previous tenants of the property or residents living in the vicinity of the property, and registered (for example, stored in the database 20).

[0090] Customizable properties can be customized by the resident (renter) to their own liking, so they can be said to be somewhere between a regular rental property, which cannot be customized, and an owner-occupied home. Customizable properties are often rented on the assumption that the tenant will live there for a long time, since the tenant is responsible for the costs of customization, such as option fees. Therefore, if there are factors that prevent long-term living, such as noise pollution or a poor surrounding environment, this assumption will be violated and the tenant will suffer disadvantages. For this reason, potential tenants may hesitate to rent a customizable property and customize it. In response to this, in the present embodiment, housing evaluation information of the customizable property is presented to prospective tenants, allowing them to grasp the level of noise and the surrounding environment in advance. This allows prospective tenants to determine whether there are any factors that would prevent them from living in the customizable property for a long period of time before renting it, thereby encouraging them to rent and customize the customizable property.

[0091] Here, the cost of customization includes option costs (costs paid through added rent). Also, if you select "DIY" or "Skeleton" as an option, costs other than the option cost will also be included. For example, if you select "DIY" wallpaper (see Figure 7), the cost of wallpaper and adhesive you prepare yourself will be included as costs other than the option cost.

[0092] <Effects> According to this embodiment, the following excellent effects are obtained. The management device 10 of this embodiment is a management device capable of communicating with a user terminal 30 used by a person wishing to rent a rental property, and is equipped with a property preference information acquisition means 11 that acquires property preference information from the user terminal 30, a candidate property search means 12 that searches for candidate properties based on the property preference information acquired by the property preference information acquisition means 11, a selection information acquisition means 13 that acquires, from the user terminal 30, property selection information regarding the property selected by the person wishing to rent and option selection information regarding the option selected by the person wishing to rent based on the search results of the candidate property search means 12, an additional rent calculation means 14 that calculates an additional rent based on the option selection information acquired by the selection information acquisition means 13, and an estimated rent presentation means 15 that presents to the person wishing to rent via the user terminal 30 the sum of the basic rent (rent when rented without options) of the property corresponding to the property selection information acquired by the selection information acquisition means 13 and the additional rent calculated by the additional rent calculation means 14 as an estimated rent.

[0093] That is, when the prospective tenant becomes a tenant, the prospective tenant can add an option to the rental property, and the option can be made conditional on paying additional rent. Since the management device 10 is equipped with the estimated rent presentation means 15, the prospective tenant can select a property and an option while checking the rent including the additional rent (estimated rent). Therefore, the rental properties managed by the management device 10 include rental properties (customizable properties) to which options selected by the tenant can be added, so that the management device 10 can provide rental properties that can be customized by the tenant. In addition, in rental properties where options selected by the tenant can be added (customizable properties), there is a high possibility that the tenant will add the option when moving in. In other words, rental properties where options selected by the tenant can be added (customizable properties) are premised on the tenant customizing the interior and layout, so the landlord of the rental property does not need to repair the interior of the property. Therefore, the landlord does not need to bear the repair costs outside the scope of the obligation to restore the property to its original condition (repair costs for aging and normal wear and tear), which reduces the landlord's burden. In other words, in rental properties where options selected by the tenant can be added (customizable properties), the landlord is responsible for the repair costs of the exterior (exterior, structure, etc.), and the tenant is responsible for the repair costs of the interior (repair costs inside the property) through the additional rent, which reduces the landlord's burden. In addition, in rental properties where tenants can add their own options (customizable properties), the tenant does not have to pay repair costs for the next tenant (repair costs within the scope of the obligation to restore the property to its original condition). In other words, there is no need to pay a deposit, which reduces the burden on the tenant.

[0094] Furthermore, rental properties that allow tenants to add their chosen options (customizable properties) are more likely to have the option added each time a new tenant changes. Therefore, the condition of the property interior improves each time a new tenant changes, which increases occupancy rates. In addition, the landlord does not have to bear the cost of such improvements, which reduces the burden on the landlord. In addition, by providing multiple customizable properties within a building (apartment complex or condominium), the building can be made up of multiple properties with different interiors and layouts. This allows differentiation from buildings (general apartment complexes) that are made up of multiple properties with the same interiors and layouts, and improves occupancy rates.

[0095] In addition, in the management device 10 of this embodiment, at least one of the interior (equipment and decoration inside the property), the layout, and the skeleton (skeleton state) can be selected as an option (see FIGS. 5 to 11). In other words, when a prospective tenant becomes a tenant, they can add options to the rental property, and by adding options, they can customize the interior (equipment and decoration inside the property) and the layout. Therefore, it is possible to effectively resolve problems such as restrictions on space and use, and not being able to live in a room of their choice.

[0096] In this embodiment, the options that can be selected, i.e., the options that can be selected on the property information presentation screen G3 (FIG. 5), are not limited to "interior", "floor plan", and "skeleton". For example, "facility plan" may be selectable as an option. In addition, the types of interior decoration (such as types of wallpaper, types of intercom, types of telework space, etc.), types of layouts, types of skeletons, types of equipment plans, etc. that can be selected in this embodiment are not limited to the types stored in the database 20. For example, at a predetermined timing (such as the time when it is determined that the property selected in step S6 is a customizable property), the management device 10 may derive selectable types using an AI (Artificial Intelligence) function or the like, and allow the prospective tenant to select from among the derived types.

[0097] Furthermore, in the management device 10 of this embodiment, DIY can be selected as an option (see FIGS. 7 to 9). In other words, prospective tenants can add options to the rental property when they become tenants, and by adding options, they can DIY the interior (equipment and decoration inside the property) and the layout. This effectively solves problems such as restrictions on space and use, and not being able to live in a room of their choice. When DIY is selected as an option, the installation of a reinforcing base may be selected as an option so that shelves or the like can be installed DIY.

[0098] Furthermore, the management device 10 of this embodiment can present a DIY support image to the prospective renter via the user terminal 30 (see FIGS. 7 to 9). In other words, prospective renters can select DIY as an option after understanding how to do it, etc. Therefore, it is possible to suppress hesitation to do DIY for reasons such as not knowing how to do it, and it is possible to promote the selection of DIY as an option.

[0099] In addition, in the case of a property where DIY can be selected as an option and where tools for DIY can be rented, the fact that tools for DIY are available for rental may be presented to prospective renters, thereby encouraging them to select DIY as an option. It would also be a good idea to create a system for the exchange of information, such as by having people teach DIY methods at workshops.

[0100] Furthermore, the management device 10 of this embodiment can present a furniture arrangement layout plan for the property selected by the prospective renter to the prospective renter via the user terminal 30 (see FIG. 10). Therefore, prospective tenants can select properties and options while checking the furniture arrangement layout.

[0101] In addition, in the management device 10 of this embodiment, it is possible to present to the prospective renter via the user terminal 30 each option that can be adopted for the property selected by the prospective renter, together with the individual additional rent (individual additional rent) that will be incurred if that option is adopted (see Figures 6 to 11). Therefore, prospective tenants can choose their options while checking the individual additional rent amounts.

[0102] Furthermore, the management device 10 of this embodiment can present information (housing evaluation information) relating to the evaluation of the property selected by the prospective renter to the prospective renter via the user terminal 30 (see FIG. 5). Therefore, prospective tenants can determine, before renting a property, whether there are any factors that would prevent them from living in the property for a long period of time, based on information about the property's evaluation, which can encourage them to rent a property that allows options to be added (customizable property) and add options (customize the property). The housing evaluation information is not limited to noise information and surrounding environment information. The housing evaluation information may include, for example, information on a utility cost simulation, specifically, information on the results of a simulation based on past utility cost data for a rental property (for example, utility cost data entered by previous tenants who rented the property) and past utility cost data for a prospective tenant.

[0103] The rental system 1 of the present embodiment further includes a management device 10 and a user terminal 30. Therefore, the rental properties handled by rental system 1 include rental properties (customizable properties) that can be fitted with options selected by the tenant, so rental system 1 can provide rental properties that can be customized by the tenant. In addition, in the case of rental properties where tenants can add options of their choice (customizable properties), the cost of repairing the exterior (exterior, structure, etc.) is borne by the landlord, while the cost of repairing the interior (repair costs inside the property) is borne by the tenant through additional rent, thereby reducing the burden on the landlord. In addition, in rental properties where tenants can add their own options (customizable properties), the tenant does not have to pay repair costs for the next tenant (repair costs within the scope of the obligation to restore the property to its original condition). In other words, there is no need to pay a deposit, which reduces the burden on the tenant.

[0104] The property information of the rental property stored in the database 20 may include information other than the various types of information described above. Specifically, for example, the property information of the rental property stored in the database 20 may include information other than the various types of information described above, such as detailed specifications of the building including the rental property, sunlight levels in summer and winter, garbage dump sites, bicycle parking areas, and local government and area culture. The property information presentation screen G3 may be configured to display substantially all of the property information of the rental property stored in the database 20. This allows a lot of information to be provided to prospective renters, thereby avoiding problems such as dissatisfaction after they start living in the property.

[0105] In addition, the rental property in this embodiment can be customized by the tenant. By customizing the rental property, the tenant can feel an attachment to the rental property and increase the possibility of living in the rental property for a long period of time. Furthermore, for example, a long-term discount system may be introduced, whereby the basic rent for a rental property is reduced according to the length of time the property is rented. This reduces the basic rent if the property is lived in for a long time, thereby increasing the possibility of the property being lived in for a long time.

[0106] [Second embodiment] Next, a second embodiment of the present invention will be described. For convenience of explanation, elements common to the first embodiment will be denoted by the same reference numerals and explanations thereof will be omitted or simplified. In the second embodiment, the base rent for the rental property is different from that in the first embodiment.

[0107] The basic rent for a rental property in the first embodiment (see FIG. 5) is the rent (first rent Ca) paid to the lessor (property owner). In contrast, the basic rent for a rental property in the second embodiment includes not only the rent (first rent Ca) paid to the lessor (property owner) but also the second rents α and β, which are rents paid to the former tenant. The second rents α and β are set based on the added value given to the rental property by the former tenant. This added value is, for example, customization of the rental property (customization of the interior, customization of the layout, etc.). Therefore, the tenant of a customizable property must bear the cost of customization, such as option costs, but the cost can be recovered after moving out of the customizable property. This can suppress hesitation to customize due to concerns about the increase in the cost of customization, and can more effectively promote renting and customizing customizable properties.

[0108] An example of the basic rent in the second embodiment will be described with reference to FIG. For example, a certain right (e.g. usufruct) related to Property Z, which is a rental property, is converted into an NFT (Non-Fungible Token). Then, as shown in Figure 12(a), the NFT of Property Z is transferred from the lessor of Property Z to Lessee A, who is the first lessee of Property Z (the first lessee after converting certain rights related to Property Z into an NFT), and from that moment on, Lessee A is obligated to pay the first rent Ca to the lessor. The basic rent paid by Lessee A, the first lessee, is only the first rent Ca. In addition, if Property Z is a customizable property and Lessee A adds options to Property Z (interior, layout, skeleton, etc.), Lessee A must pay additional rent.

[0109] When Lessee A moves out of Property Z, as shown in Figure 12(b), the NFT of Property Z is transferred to Lessee B, the second lessee of Property Z (the second lessee after converting certain rights related to Property Z into NFTs), and from that moment on, Lessee B is obligated to pay the first rent Ca to the lessor. In addition, if Lessee A, the former lessee, adds value to Property Z by customizing Property Z, Lessee A can request Lessee B to pay the second rent α, which is the rent based on that added value. Therefore, the basic rent paid by Lessee B, the second lessee, is the sum of the first rent Ca and the second rent α. In addition, if Lessee B adds an option to Property Z, Lessee B must pay an additional rent.

[0110] When Lessee B moves out of Property Z, as shown in Figure 12(c), the NFT of Property Z is transferred to Lessee C, who is the third lessee of Property Z (the third lessee after converting certain rights related to Property Z into NFTs), and from that moment on, Lessee C is obligated to pay the first rent Ca to the lessor. In addition, if Lessee A, the former lessee, adds value to Property Z by customizing Property Z, Lessee A can request Lessee C to pay the second rent α, which is the rent based on that added value. In addition, if Lessee B, the former lessee, adds value to Property Z by customizing Property Z, Lessee B can request Lessee C to pay the second rent β, which is the rent based on that added value. Therefore, the basic rent paid by Lessee C, the third lessee, is the sum of the first rent Ca, the second rent α, and the second rent β. In addition, if Lessee C adds an option to Property Z, Lessee C will have to pay an additional rent. Even after Tenant C moves out of Property Z, the base rent for Property Z is set in the same manner.

[0111] In this embodiment, when the second rent α has been paid to the tenant A n times (e.g., 36 times), the payment of the second rent α to the tenant A is deemed to have ended. Similarly, when the second rent β has been paid to the tenant B n times (e.g., 36 times), the payment of the second rent β to the tenant B is deemed to have ended.

[0112] Therefore, during the period in which the tenant of property Z is tenant B, tenant B pays second rent α n times (for example, 36 times) to former tenant A, and when payment of second rent α to tenant A is completed, the basic rent paid by tenant B thereafter will be only first rent Ca. Also, if the tenant of property Z becomes tenant C after payment of second rent α to tenant A is completed, the basic rent paid by tenant C will be first rent Ca and second rent β. The same applies when payment of second rent β to tenant B is completed. In addition, during the period in which the tenant of property Z is tenant C, if tenants B and C pay second rent α to tenant A n times (for example, 36 times) and the payment of second rent α to tenant A is completed, the base rent paid by tenant C thereafter will be first rent Ca and second rent β. The same applies when the payment of second rent β to tenant B is completed.

[0113] FIG. 13 is a block diagram showing an example of the configuration of the rental system 1 in the second embodiment. The second embodiment differs from the first embodiment in that the database 20 stores added value information. In the second embodiment, the functions of the management device 10 are different from those in the first embodiment. Specifically, the management device 10 in the second embodiment includes a property request information acquisition means 11, a candidate property search means 12, a selection information acquisition means 13, an additional rent calculation means 14, and an estimated rent presentation means 15, as well as a first determination means 16 and a second determination means 17, as shown in FIG.

[0114] The database 20 of this embodiment stores various information necessary for the rental system 1 of this embodiment. Specifically, in addition to property information about rental properties, the database 20 stores, for each property, added value information about added value given to the rental property. The added value information of rental properties stored in database 20 includes, for example, information regarding options actually added to the rental property (interior and its type, floor plan and its type, skeleton and its type, etc.), and the user ID of the tenant (including former tenant) who added the option.

[0115] In addition, the added value information of the rental property stored in database 20 includes cost information that allows the tenant to know the cost of renovating the rental property when the tenant renovates it themselves when moving in, during the tenancy, or when moving out, as well as the user ID of the tenant (including former tenant). Here, the cost information may be, for example, the cost of remodeling (renovation) input directly by the tenant, or it may be an image (such as an interior photo) showing the state of the interior of the property after remodeling (renovation). By storing the cost information, it becomes possible to determine the value of the interior of the property more accurately. For example, when the added option is a skeleton, or when the added option is an interior and the type of the interior (such as the type of wallpaper, the type of intercom, or the type of telework space) is "DIY", the value of the interior of the property may not be determined based on the options actually added to the rental property. Even in such cases, if the cost information of the rental property is stored, it is possible to determine the value of the interior of the rental property based on the cost information.

[0116] Furthermore, the added value information of the rental property stored in database 20 includes, for example, information regarding furniture and appliances left behind when moving out of the rental property and the user ID of the former tenant who left that furniture and appliances behind, information regarding services that improve the convenience of the rental property (for example, a service of regularly delivering shopping from a nearby supermarket to the rental property) and the user ID of the tenant (including the former tenant) who added that service, home appraisal information for the rental property, and the user ID of the tenant (including the former tenant) who entered the home appraisal information.

[0117] As shown in FIG. 13, the management device 10 includes a first determination means 16 for determining a first rent Ca to be paid to a lessor of a rental property. The first determination means 16 determines the first rent Ca for a rental property based on the value of the rental property (excluding added value added by the tenant) and the market price of surrounding properties, etc. The value of the rental property used to determine the first rent Ca is value other than added value added by the tenant (including the former tenant) to the rental property, and specifically includes, for example, the exterior of the rental property (appearance and structure), the area in which the building including the rental property is located, the nearest station, the distance from the nearest station, the exclusive area, the age of the building, the facilities (excluding facilities added by the tenant) and features, information on the common areas, etc. The first rent Ca may be renewed periodically (for example, every two years) or when the tenant changes.

[0118] Furthermore, the first determination means 16 transmits data for displaying the determined first rent Ca to an information terminal (not shown) used by the lessor via the communication network N. As a result, the first rent Ca determined by the first determination means 16 is presented to the lessor via the information terminal. If the lessor does not approve the presented first rent Ca, the first determination means 16 may recalculate the first rent Ca. Alternatively, the first determination means 16 may calculate a reasonable range for the first rent Ca and present it to the lessor, so that the lessor can determine the first rent Ca from within that range.

[0119] As shown in FIG. 13, the management device 10 further includes a second determination means 17 for determining second rents α, β, . . . to be paid to the former tenant of the rental property. The second determination means 17 determines the second rent based on the added value given to the rental property by the former lessee. Specifically, the second determination means 17 calculates an amount equivalent to the added value given to the rental property by the former lessee based on the added value information of the rental property stored in the database 20. Then, the second determination means 17 determines the amount obtained by dividing the calculated amount by n (e.g., n=36) as the second rent.

[0120] Specifically, for example, as shown in Figure 12(b), when the NFT of property Z is transferred from lessee A to another lessee, that is, when lessee A notifies the lessee that he or she will be moving out of property Z and a new lessee is recruited, the second determination means 17 extracts information stored together with lessee A's user ID from the added value information of property Z stored in database 20, and calculates an equivalent amount corresponding to the added value that lessee A has given to property Z based on the extracted information. Then, the second determination means 17 divides the calculated equivalent amount by n (e.g., 36) to obtain the second rent α. As described above, the payment of the second rent α to the lessee A ends when the number of such payments reaches n (for example, 36).

[0121] Furthermore, the second determination means 17 transmits data for displaying the determined second rent α to the user terminal 30 used by the lessee A via the communication network N. As a result, the second rent α determined by the second determination means 17 is presented to the lessee A via the user terminal 30. If the lessee A does not approve the presented second rent α, the second determination means 17 may recalculate the second rent α. Alternatively, the second determination means 17 may calculate a reasonable range for the second rent α and present it to the lessee A, so that the lessee A may determine the second rent α from within that range. Then, the sum of the first rent Ca determined by the first determination means 16 and the second rent α determined by the second determination means 17 is displayed as the basic rent on a property information presentation screen (Figure 5) for recruiting new tenants, and is presented to prospective tenants such as tenant B via user terminal 30.

[0122] Furthermore, as shown in Figure 12(c), for example, when the NFT of property Z is transferred from lessee B to another lessee, that is, when lessee B notifies the lessee that he / she will be moving out of property Z and a new lessee is sought, the second determination means 17 extracts information stored together with lessee B's user ID from the added value information of property Z stored in database 20, and calculates an equivalent amount corresponding to the added value that lessee B has given to property Z based on the extracted information. The second determination means 17 then divides the calculated equivalent amount by n (e.g., 36) to obtain the second rent β. As described above, the payment of the second rent β to the lessee B ends when the number of such payments reaches n (for example, 36).

[0123] Furthermore, the second determination means 17 transmits data for displaying the determined second rent β to the user terminal 30 used by the lessee B via the communication network N. As a result, the second rent β determined by the second determination means 17 is presented to the lessee B via the user terminal 30. If the lessee B does not approve the proposed second rent β, the second determination means 17 may recalculate the second rent β. Alternatively, the second determination means 17 may calculate a reasonable range for the second rent β and present it to the lessee B, so that the lessee B determines the second rent β from within that range.

[0124] Then, if payment of the second rent α to tenant A has not been completed, the sum of the first rent Ca determined by the first determination means 16, the second rent α determined by the second determination means 17 (for example, the second rent α determined when recruiting a new tenant upon receiving notice from tenant A that he will be moving out of property Z), and the second rent β determined by the second determination means 17 is displayed as the basic rent on a property information presentation screen (Figure 5) for recruiting new tenants, and is presented to prospective tenants such as tenant C via the user terminal 30. In addition, when payment of the second rent α to tenant A has been completed, the sum of the first rent Ca determined by the first determination means 16 and the second rent β determined by the second determination means 17 is displayed as the basic rent on the property information presentation screen (Figure 5) for recruiting new tenants, and is presented to prospective tenants such as tenant C via the user terminal 30.

[0125] <Effects> According to this embodiment, in addition to the effects of the first embodiment, the following excellent effects are achieved. The management device 10 of this embodiment is a management device capable of communicating with a user terminal 30 used by a tenant (including a former tenant) of a rental property, and is equipped with a first determination means 16 that determines a first rent Ca to be paid to the landlord of the rental property, and a second determination means 17 that determines second rents α, β to be paid to the former tenant of the rental property.The second determination means 17 determines the second rents α, β based on the added value that tenants A and B (second tenants) have added to the rental property, and transmits data for displaying the determined second rents α, β to the user terminal 30 used by tenants A and B (second tenants). Then, during the period when the tenant of the rental property is Lessee B (first lessee), a first rent Ca is paid to the lessor, and a second rent α is paid to Lessee A (second lessee), who is the tenant before Lessee B, as shown in Figure 12(b). In addition, during the period when the tenant of the rental property is tenant C (first tenant), as shown in Figure 12(c), a first rent Ca is paid to the lessor, and second rent α and second rent β are paid, respectively, to tenant A (second tenant) and tenant B (second tenant), who are tenants prior to tenant C.

[0126] In other words, tenants can add value to a rental property and, after moving out of the property, can receive a second rent based on the added value they added, which allows them to feel satisfied with the rental costs. In addition, since the tenant adds value to the rental property, the landlord does not need to add value to the rental property. Therefore, the landlord does not need to bear the cost of adding value, and can feel satisfied with the rental expenses.

[0127] The second determination means 17 may determine the second rent based on the added value given to the rental property by the tenant and the tenant evaluation information. The tenant evaluation information is, for example, credit information on the evaluation of the tenant, which is input by a real estate agent or a property owner and registered in the database 20. Specifically, the tenant evaluation information is, for example, information showing the past usage status of the tenant in past rental properties, such as photos taken at the time of moving in (after cleaning) and at the time of moving out (before cleaning), information showing the repair costs incurred at the time of moving out of past rental properties, and information showing the tenant's behavior in past rental properties (the number of complaints from other tenants, the presence or absence of trouble, the rent payment status, etc.). In other words, the second determination means 17 may set the second rent calculated based on the added value added by the tenant as the standard second rent, and if the tenant's evaluation is high, determine a rent higher than the standard second rent as the second rent to be paid to the tenant, if the tenant's evaluation is average, determine a rent equal to the standard second rent as the second rent to be paid to the tenant, and if the tenant's evaluation is low, determine a rent lower than the standard second rent as the second rent to be paid to the tenant.

[0128] Furthermore, the candidate property search means 12 of this embodiment (and the candidate property search means 12 of the first embodiment) may be configured to search for candidate properties based on the property preference information acquired by the property preference information acquisition means 11 and the tenant evaluation information stored in the database 20. That is, a lessor of a rental property may select tenants for the rental property based on tenant evaluation information. Specifically, there may be rental properties that can only be rented by tenants with high evaluations.

[0129] In addition, the first determination means 16 may determine the first rent Ca based on the value of the rental property (excluding any added value added by the tenant), the market prices of surrounding properties, and tenant evaluation information stored in the database 20. Specifically, the first determination means 16 may determine the first rent calculated based on the value of the rental property rented by the tenant (excluding any added value added by the tenant) and the market price of surrounding properties as the standard first rent, and if the tenant's evaluation is high, may determine a rent lower than the standard first rent as the first rent to be paid by the tenant, if the tenant's evaluation is average, may determine a rent equal to the standard first rent as the first rent to be paid by the tenant, and if the tenant's evaluation is low, may determine a rent higher than the standard first rent as the first rent to be paid by the tenant.

[0130] Furthermore, the management device 10 of this embodiment (and the management device 10 of the first embodiment) may extract tenant evaluation information of the prospective tenant from a plurality of tenant evaluation information stored in the database 20, and present the extracted tenant evaluation information to the lessor (property owner) or real estate agent of the property selected by the prospective tenant. This allows the lessor or real estate agent to check the evaluation of the prospective tenant before entering into a rental contract, allowing them to rent out the property with peace of mind.

[0131] In addition, in the management device 10 of this embodiment, when the second rent α has been paid n times (e.g., 36 times) to the lessee A (second lessee), the payment of the second rent α to the lessee A can be terminated. In addition, when the second rent β has been paid n times (e.g., 36 times) to the lessee B (second lessee), the payment of the second rent β to the lessee B can be terminated. Therefore, the second rent will not be added for each former tenant, so an increase in the second rent can be prevented.

[0132] In addition, in the management device 10 of this embodiment, the second determination means 17 can determine the second rents α and β as the amount equivalent to the added value added by tenants A and B (second tenants) to the rental property divided by n (n is an integer greater than or equal to 2, for example, n=36). Therefore, the former tenant can reliably recover the costs incurred in providing added value. Specifically, the former tenant can reliably recover the actual costs incurred, such as the costs incurred in customizing the interior and layout, and the costs incurred in purchasing furniture and appliances. Furthermore, if the tenant registers for a service that improves the convenience of the rental property as added value, the equivalent amount will be included in the second rent, and if the tenant enters home evaluation information for the rental property as added value, the equivalent amount will be included in the second rent, so the former tenant can also recover the labor costs. In addition, since the costs incurred in adding added value can be reliably recovered, it is possible to encourage tenants to add added value to rental properties.

[0133] Furthermore, the management device 10 of this embodiment can present the sum of the first rent and the second rent as the rent (basic rent) of the rental property to a person who wishes to rent the rental property via the user terminal 30. Specifically, for example, when tenant B, who will be the next tenant of property Z after tenant A, is looking for a rental property, the management device 10 presents the sum of the first rent Ca and the second rent α as the basic rent for property Z to tenant B via the user terminal 30 (see Figure 5). Also, for example, when tenant C, who will be the next tenant of property Z after tenant B, is looking for a rental property, the management device 10 presents the sum of the first rent Ca and the second rents α and β as the basic rent for property Z to tenant C via the user terminal 30 (see Figure 5). Therefore, the rent including the second rent is presented to the prospective tenant, so that the prospective tenant (tenant) can feel satisfied with the costs involved in renting.

[0134] In addition, the management device 10 of this embodiment is equipped with an additional rent calculation means 14 that calculates additional rent based on added value (options) that the prospective tenant plans to add to the rental property, and an estimated rent presentation means 15 that presents to the prospective tenant the sum of the basic rent (rent when renting without the option), which is the sum of the first rent and the second rent, and the additional rent calculated by the additional rent calculation means 14 as an estimated rent. Specifically, for example, when tenant B, who will be the next tenant of property Z after tenant A, is searching for a rental property, the additional rent calculation means 14 calculates the additional rent based on the added value that tenant B plans to add to property Z, and the estimated rent presentation means 15 presents the sum of the basic rent, which is the sum of the first rent Ca and the second rent α, and the additional rent calculated by the additional rent calculation means 14 as the estimated rent to tenant B via the user terminal 30. Also, for example, when tenant C, who will be the next tenant of property Z after tenant B, is searching for a rental property, the additional rent calculation means 14 calculates the additional rent based on the added value that tenant C plans to add to property Z, and the estimated rent presentation means 15 presents to tenant C via the user terminal 30 the sum of the basic rent, which is the sum of the first rent Ca and the second rents α, β, and the additional rent calculated by the additional rent calculation means 14 as the estimated rent.

[0135] In other words, when the prospective tenant becomes a tenant, the prospective tenant can add value (specifically, an option among the added values) to the rental property, and the added value can be added on the condition that an additional rent is paid. And, since the management device 10 is equipped with the estimated rent presentation means 15, the prospective tenant can select a property and an added value while checking the rent including the additional rent (estimated rent).

[0136] The rental system 1 of the present embodiment further includes a management device 10 and a user terminal 30. In other words, tenants can add value to a rental property and, after moving out of the property, can receive a second rent based on the added value they added, which allows them to feel satisfied with the rental costs. In addition, since the tenant adds value to the rental property, the landlord does not need to add value to the rental property. Therefore, the landlord does not need to bear the cost of adding value, and can feel satisfied with the rental expenses.

[0137] In recent years, there has also been a call to achieve the goals of the SDGs (Sustainable Development Goals), and various initiatives are being undertaken in the construction industry. The rental property in the first and second embodiments can be customized by the tenant. By customizing the rental property, the tenant can feel attached to the rental property and increase the possibility of living in the property for a long time, which can reduce the frequency of moving. Moving generates a large amount of garbage and requires the operation of moving vehicles, which emits carbon dioxide, but reducing the frequency of moving can contribute to reducing carbon dioxide (Goal 13).
