Description

[Technical Field]

[0001] The present invention relates to a real estate information providing device, a real estate information providing method, and a program. [Background technology]

[0002] As awareness of environmental issues and the need for efficient resource utilization grows, the trend of placing too much emphasis on new real estate construction is being reassessed, and the market for used housing, including used condominiums, is becoming more active. For example, Patent Document 1 describes a real estate purchasing system that is connected to a network and supports the purchase of real estate, and that includes a network communication means that is connected to the network and sends and receives real estate information and user information, a property registration means that registers real estate property information received by the network communication means, and a property provision means that prepares property provision information to be provided on the network from the property information registered by the property registration means, and the network communication means discloses the property provision information prepared by the property provision means via the network.

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2002-024596 Summary of the Invention [Problem to be solved by the invention]

[0004] Let me explain the general flow of real estate transactions, for example, used property transactions. When the owner of a used property considering selling contacts a real estate agent (whether a real estate agent or a resale buyer) and expresses their intention to sell, information about the property, including the desired selling price, is made public as a for-sale property. When a potential buyer of the used property expresses an interest in the property, they notify the agent of their intention to purchase, and negotiations for the real estate transaction begin between the potential seller and the agent. The desired selling price of potential sellers is determined based on various real estate information, such as the exclusive area, floor plan, and age of the property, taking into account fluctuating market prices. Furthermore, renovating a property increases its asset value, and the sales price at which a contract is reached tends to be higher than the market price. However, conventional real estate search systems have had difficulty actively using information about renovations to provide both sellers and buyers with information they can use to consider real estate transactions.

[0005] The object of the present invention is to solve such problems, and specifically to provide information regarding renovation implementation that can be used to consider real estate transactions, compared to when the present invention is not applied. [Means for solving the problem]

[0006] With this objective in mind, the present invention is a real estate information providing device that includes a processor, which acquires search information for searching for real estate information including a selling price, the search information including specific information that identifies at least one of a plurality of groups that are predetermined based on information regarding the implementation of construction work on the real estate, and outputs, as a search result based on the acquired search information, resultant real estate information that belongs to the group identified by the specific information and satisfies the search information other than the specific information. Here, the information regarding the implementation of the construction work may include information indicating whether or not construction work is to be carried out to make the property the same as when it was first built or to bring it close to that state, and the extent of the construction work, if any. Furthermore, the extent of the construction work, if any, may be set based on information indicating the items of the construction work to be carried out. The extent of the work, if any, can be set based on whether the work items are all or part of the work items that can be carried out on the real estate. The extent of the work, if any, can be set based on whether the work items include equipment renewal. The extent of the work, if any, can be set based on whether the work items include refinishing. Furthermore, the search information may include occupancy information indicating whether the property is currently occupied. Furthermore, the output of the resultant real estate information may include a display of the resultant real estate information divided into a first period and a second period different from the first period, and the price displayed for either the first period or the second period may be corrected based on the price displayed for the other period. Another invention that achieves the above-mentioned object is a real estate information providing method that acquires search information for searching for real estate information including a selling price, the search information including specific information that identifies at least one of a plurality of groups that are predetermined based on information regarding the implementation of construction work on the real estate, and outputs, as a search result based on the acquired search information, result real estate information that belongs to the group identified by the specific information and satisfies the search information other than the specific information. Another invention that achieves the above-mentioned object is a program that enables an information processing device to perform the following functions: acquire search information for searching for real estate information including a selling price, the search information including specific information that identifies at least one of a plurality of groups that are predetermined based on information regarding the implementation of construction work on the real estate; and output resultant real estate information as a search result based on the acquired search information, the real estate information belonging to the group identified by the specific information and satisfying the search information other than the specific information. [Effects of the Invention]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 is a diagram showing an example of the overall configuration of a real estate information providing system 1 according to this embodiment. The real estate information providing system 1 according to this embodiment is a system that provides real estate information, including information regarding renovations, to those considering a real estate transaction for a used property. For example, an owner of a used property considering selling may use the information regarding renovations to consider the desired selling price. Another possible case is when a person considering purchasing a used property uses the information to consider the appropriateness of the desired selling price. Such considerations can be made in more detail by comparing the real estate information, including the information regarding renovations, with other used properties.

[0010] The real estate information providing system 1 includes a terminal 10, a real estate information providing device 20, and a database 30. The terminal 10 and the real estate information providing device 20 are connected via a network 40. The real estate information providing device 20 and the database 30 are internally connected.

[0011] The terminal 10 is a terminal of a person considering a real estate transaction, and may be a terminal of an owner of a used property who is considering selling it, or a terminal of a person who is considering purchasing a used property. The terminal 10 may also be a terminal of a dealer who deals in used real estate. The terminal 10 transmits search information for acquiring information necessary for considering a real estate transaction to the real estate information providing device 20, and receives search results from the real estate information providing device 20. The terminal 10 also transmits display format information, which is information indicating the display format of the search results, to the real estate information providing device 20, and receives search results according to the display format of the search results.

[0012] When the real estate information providing device 20 receives search information transmitted from the terminal 10, it searches the real estate information held in the database 30 and transmits information displaying the search results in a predetermined format to the terminal 10. Furthermore, when the real estate information providing device 20 receives display format information transmitted from the terminal 10, it transmits search results according to the display format information.

[0013] The database 30 stores real estate information on purchased new properties and used properties. The database 30 stores the results of analysis by the real estate information providing device 20. The analysis by the real estate information providing device 20 uses the real estate information stored in the database 30. The real estate information referred to here refers to information that includes information indicating the details of the real estate, as well as information regarding the sale and purchase of the real estate and information regarding the implementation of construction work on the real estate. More specifically, based on information regarding the building, such as the address, the database 30 stores information regarding newly constructed properties and information regarding used properties that have been sold after the new construction, in association with each other. Furthermore, for each used property, the database 30 stores information regarding the sale and purchase, such as the selling price, and information regarding the implementation of renovation work, in association with each other.

[0014] The information regarding the construction work being carried out on real estate mentioned here includes information indicating whether or not there has been any renovation work (hereinafter referred to as "remodeling work"), which is work to make the house the same as when it was first built or close to that state.In addition, the information regarding the construction work being carried out on real estate may also include information indicating whether or not there has been any renovation work and, if there has been any, the extent of the renovation work. The extent of the remodeling work referred to here may be determined by information indicating the items to be implemented, or by information indicating the cost of the work. Remodeling work may include changing the floor plan, or adding new functions or value to make the resident's life more comfortable (so-called renovation). Repairing only the broken parts does not qualify as renovation work, but if the repairs are included in part of the building, it does qualify as renovation work. In the case of condominiums, renovation work is carried out on the exclusive areas.

[0015] The database 30 may store real estate information for properties including not only used homes but also newly built homes. That is, the database 30 stores information on residential properties. Residential properties include apartment complexes and other residential buildings, as well as detached houses. In the case of condominiums, the information is the unit of the apartment. Residential properties also include new and used condominiums, which are newly built condominiums for which a sales contract has not been concluded even after a predetermined number of years have passed since construction.

[0016] When the real estate information providing device 20 acquires information about buying and selling or information about the implementation of renovation, the real estate information providing device 20 performs processing to associate the information with previously acquired property information and stores the information in the database 30.

[0017] The real estate information providing device 20 is realized by, for example, an information processing device such as a computer. The real estate information providing device 20 may be configured by a single computer, or may be realized by distributed processing using a plurality of computers.

[0018] As described above, the terminal 10 is a device of a person who is considering selling or purchasing real estate, and may be a real estate purchasing agent or real estate broker. The terminal 10 is realized, for example, by a PC (Personal Computer) or the like. In this embodiment, a configuration example is adopted in which the terminal 10 and the real estate information providing device 20 are the same device, but this is not limiting, and a configuration example in which they are different devices may also be adopted.

[0019] Furthermore, the type of network 40 used to connect the terminal 10 and the real estate information providing device 20 is not particularly limited as long as it is capable of transmitting and receiving data. The network 40 may be, for example, the Internet, a LAN (Local Area Network), a WAN (Wide Area Network), etc. The communication line used for data communication may be wired or wireless. Furthermore, the configuration for connecting each device may be via multiple networks 40 or communication lines.

[0020] <Hardware configuration example> FIG. 2 is a diagram showing an example of the hardware configuration of the terminal 10 and the real estate information providing device 20. As shown in FIG. 2, each of the terminal 10 and the real estate information providing device 20 includes a CPU (Central Processing Unit) 100a as a computing means and a memory 100c as a main storage means. Each device also includes external devices such as a magnetic disk device (HDD: Hard Disk Drive) 100g, a network interface 100f, a display mechanism 100d, an audio mechanism 100h, and input devices 100i such as a keyboard and a mouse.

[0021] The memory 100c and the display mechanism 100d are connected to the CPU 100a via the system controller 100b. The network interface 100f, the magnetic disk drive 100g, the audio mechanism 100h, and the input device 100i are connected to the system controller 100b via the I / O controller 100e. Each component is connected by various buses such as a system bus and an input / output bus.

[0022] The magnetic disk device 100g stores programs for implementing various functions. These programs are loaded into the memory 100c, and the CPU 100a executes processes based on these programs, thereby implementing various functions.

[0023] <Functional configuration of real estate information providing device 20> Next, the functional configuration of the real estate information providing device 20 will be described. FIG. 3 is a diagram illustrating an example of the functional configuration of the real estate information providing device 20. As shown in FIG. The real estate information providing device 20 includes a search information receiving unit 21, a display format information receiving unit 22, a real estate information acquiring unit 23, a search executing unit 24, a display format information holding unit 25, and an output unit 26.

[0024] The search information receiving unit 21, the display format information receiving unit 22, the real estate information acquiring unit 23, and the output unit 26 are a network interface for connecting to a business operator's terminal 10 (see FIG. 1) via a network 40 (see FIG. 1). This allows the real estate information providing device 20 to exchange data with the terminal 10.

[0025] The search information receiving unit 21 receives search information sent from the terminal 10 (see FIG. 1). The search information here is information for searching real estate information and includes the selling price. The search information here also includes specific information that identifies at least one of a plurality of groups that are predetermined based on information about renovations. The information regarding renovation is information including whether or not renovation has been carried out on the real estate and, if renovation has been carried out, the items to be implemented.

[0026] The display format information receiving unit 22 receives display format information, which is information indicating the display format for displaying search results based on search information. The display format information here is information indicating the layout when the search results are displayed on the screen of the terminal 10 (see FIG. 1), and may include a map of the area around the searched property, details of the searched property, graphs based on data including the searched property and other properties, etc.

[0027] The real estate information acquisition unit 23 acquires real estate information held in the database 30 (see FIG. 1). As described above, real estate information refers to information including information on the details of real estate, information on the buying and selling of real estate, and information on the implementation of construction work on real estate.

[0028] The search execution unit 24 uses the search information received by the search information receiving unit 21 to search for real estate information to be acquired by the real estate information acquisition unit 23. The search information here includes specific information that identifies at least one of a plurality of groups that are predetermined based on information related to the implementation of construction work on real estate.

[0029] The display format information storage unit 25 stores the display format information received by the display format information receiving unit 22. The display format information storage unit 25 stores the initial setting display format information, and when new display format information is received by the display format information receiving unit 22, updates the stored display format information.

[0030] The output unit 26 creates display data based on the search results from the search execution unit 24 in accordance with the display format information stored in the display format information storage unit 25, and outputs the data to the terminal 10 (see FIG. 1). The output occurs when a search is performed by the search execution unit 24 or when display format information is received by the display format information receiving unit 22.

[0031] Next, the real estate information stored in the database 30 will be described. FIG. 4 is a table illustrating an example of the contents of real estate information stored in the database 30. The content example of real estate information shown in Figure 4 is managed by dividing it into major items and minor items. Major items include location, apartment information, and individual unit information. The location sub-items include the address, line, name of the nearest station, and walking distance from the station. The apartment information sub-items include the apartment name, land rights, management type, total number of units, structure, year of construction, and number of floors (top floor). The land rights will be indicated as either ownership or fixed-term leasehold. The management type will be indicated as either entrusted or self-managed. The structure will be indicated as either reinforced concrete (SRC) or reinforced concrete (RC), etc.

[0032] Sub-items of information for each unit include the exclusive area, balcony area, orientation, floor location, and layout. In addition, the sub-items of the household information include whether or not the home has been remodeled, and if so, the degree of remodeling, which indicates the extent of the remodeling.

[0033] The degree of renovation can be, for example, one of five: full renovation (complete renovation), partial renovation, renovation with equipment renewal, surface renovation, and no renovation. Full renovation and partial renovation here refer to cases where both equipment renewal and surface renovation have been carried out, and the difference lies in whether the extent of renovation is complete or partial. Renovation with equipment renewal is when the equipment has been renewed but the surface has not been renovated, and surface renovation is when the surface has been renovated but the equipment has not been renewed. Information on the degree of renovation like this is useful for setting and considering the purchase and sale price.

[0034] In addition, the sub-items of the individual unit information include monthly repair reserves and management fees calculated based on the exclusive area.

[0035] Furthermore, the subitems of the unit information include, as information in the case of a real estate transaction for a used property, the starting sales price, the closing sales price, the starting sales date, the closing sales date, the number of price reductions, the amount of price reduction, the date of the price reduction, and the sales period. In the example shown in Figure 4, the sales period is 60 days from January 1 to March 1, 2024, and the starting sales price is 60 million yen, but the price is reduced by a total of 10 million yen three times on January 31, February 1, and February 29, resulting in a closing sales price of 50 million yen. In other words, Figure 4 illustrates a history in which a real estate purchase and sale contract was concluded for 50 million yen after a price reduction of 10 million yen. Such information showing past real estate transactions is useful for setting future purchase and sale prices.

[0036] The above-mentioned small items are merely examples, and it is conceivable that some small items are not included, or that other small items are included. For example, the location sub-item may include information on whether there is a school nearby. Other sub-items of apartment building information may include, for example, information on damage forecast maps or hazard maps created for each type of disaster. The subitems of the individual unit information may include, for example, the time of renovation. The subitems of the individual unit information may also include information indicating whether the repair fund is a stepped-up fund method or an equal-rate fund method. The subitems of the individual unit information may also include whether there is a parking lot or a bicycle parking lot. The subitems of the individual unit information may also include the selling price of a new building.

[0037] Next, an example of a processing procedure for classifying the degree of renovation included in the real estate information stored in the database 30 (see FIG. 4) will be described. 5 is a flowchart showing an example of a processing procedure for classifying the degree of renovation. In this example of processing procedure, processing is performed in the real estate information providing device 20 (see FIG. 1), and the classification results are held in the database 30 as part of the real estate information. 5, when the real estate information providing device 20 acquires information about a used property (step 101), the real estate information providing device 20 determines whether or not remodeling work has been carried out (step 102). For example, if the information about the used property includes information indicating the implementation items of remodeling work, it can be determined that remodeling work has been carried out, and if such information is not included, it can be determined that remodeling work has not been carried out.

[0038] If renovation work has been carried out (Yes in step 102), the real estate information providing device 20 determines whether or not the renovation work has included refinishing and equipment updates (step 103). For example, if the implementation items for the renovation work include an item related to refinishing and an item related to equipment, it is determined that the renovation work has included refinishing and equipment updates. If only one of the items is included, it can be determined that the renovation work has not included refinishing or equipment updates. The term "surface" as used here refers to the finishing of the surfaces of walls, floors, ceilings, etc., and may include the renovation of fixtures and fittings. The term "equipment" as used here refers to, for example, system kitchens, hot water heaters, bathroom dryers, air conditioners, floor heating panels, etc., and "equipment renewal" refers to replacing such equipment with new ones, including the installation of new equipment.

[0039] If the renovation work involves refinishing and updating of facilities (Yes in step 103), it is determined whether the renovation work has been completed comprehensively (step 104). If the remodeling work includes all of the work items that can be performed on a used property, it can be determined that the remodeling work has been completed completely, and if only some of the work has been performed, it can be determined that the remodeling work has not been completed completely. For example, if the walls, floors, and ceilings in all rooms have been replaced and all equipment has been replaced, it can be determined that the remodeling work has been completed completely. If this is not the case, it can be determined that the remodeling work has not been completed completely.

[0040] If the renovation work has been completed completely (Yes in step 104), the real estate information providing device 20 classifies the degree of renovation of the used property as "01_full" (step 105). If the renovation work has not been completed completely (No in step 104), the real estate information providing device 20 classifies the degree of renovation of the used property as "02_partial" (step 106).

[0041] If the renovation work does not include refinishing or equipment renewal (No in step 103), the real estate information providing device 20 determines whether the renovation work involves only equipment renewal (step 107). If the renovation work involves only equipment renewal (Yes in step 107), the real estate information providing apparatus 20 classifies the degree of renovation of the used property into "03_equipment renewal" (step 108).

[0042] If the renovation work is not just facility renewal (No in step 107), the real estate information providing device 20 classifies the degree of renovation of the used property as "04_renovation" since the renovation work is just renovating (step 109).

[0043] If no renovation work has been carried out (No in step 102), the real estate information providing apparatus 20 classifies the degree of renovation of the used property as "05_none" (step 110).

[0044] The information about the used property described above is an example of information about the implementation of work on real estate, and is an example of information indicating whether or not work has been done to make the property the same as when it was first built or to bring it close to that state. Furthermore, the information indicating the items of remodeling work included in the information about the used property is an example of information indicating the extent of the work. Each of the classified renovation degrees "01_full," "02_partial," "03_equipment renewal," "04_surface repair," and "05_none" is an example of a plurality of groups that are predetermined based on information regarding the implementation of construction work on real estate.

[0045] In this embodiment, the degree of renovation is classified into five categories, but this is not limited to this. For example, a modified example can be considered in which the degree of renovation is classified into two categories, "01_full," "02_partial," "03_equipment renewal," "04_surface modification," and "05_none," based on whether or not renovation work has been carried out. Another possible variation is to classify the renovation work into two categories, "01_full," "02_partial," "03_equipment renewal," and "04_surface replacement," based on whether the renovation work has been carried out completely or not. Furthermore, from the viewpoint of whether or not equipment has been updated, it is possible to classify the products into two categories: "01_full," "02_partial," and "03_equipment update" with equipment update, and "04_mounted" without equipment update. Still further, from the viewpoint of whether or not equipment has been mounted, it is possible to classify the products into two categories: "01_full," "02_partial," and "04_mounted" with mounting, and "03_equipment update" without mounting.

[0046] In this embodiment, the processing procedure for classifying the degree of renovation in the real estate information providing device 20 has been described, but the present invention is not limited to this and can also be realized using a machine learning model. By performing machine learning using information on the implementation of construction work on real estate and information on the degree of renovation as training data, a model for classifying the degree of renovation can be constructed.

[0047] In addition, in this embodiment, the degree of renovation is classified based on the implementation items of the renovation work, from the viewpoint of whether the renovation work has been carried out completely, and whether the remodeling and / or equipment has been updated, but this is not limited to this. For example, it is possible to assign a score to each implementation item of the renovation work and classify the degree of renovation based on the total score.

[0048] FIG. 6 is a flowchart showing an example of the search processing procedure of the real estate information providing apparatus 20. In the processing procedure shown in Figure 6, when the search information receiving unit 21 (see Figure 3) receives search information from the terminal 10 (see Figure 1) (step 201), the real estate information acquisition unit 23 (see the same figure) acquires real estate information from the database 30 (see Figure 1) (step 202).

[0049] Next, the search execution unit 24 (see FIG. 3) uses the search information to search for real estate information (step 203). The search information includes specific information that identifies at least one of the renovation degrees "01_full," "02_partial," "03_equipment update," "04_facelift," and "05_none." For example, the specific information may be only the renovation degree "01_full," or only the renovation degrees "01_full" and "02_partial," or may be all renovation degrees. The information on the renovation degree included in the search information is an example of specific information. In addition to the specific information described above, the search information may also include information other than the specific information, such as the name of the nearest station, the number of minutes to walk from the station, the exclusive area, and the layout.

[0050] Then, when a search is performed by the search execution unit 24, the output unit 26 (see FIG. 3) uses the display format information stored in the display format information storage unit 25 to create display data that displays the search results in a display format (step 204). The real estate information displayed in the display data is an example of result real estate information. The created display data is output from the output unit 26 (see FIG. 3) to the terminal 10 (see FIG. 1) (step 205).

[0051] It is determined whether the display format information receiving unit 22 (see FIG. 3) has received the display format information from the terminal 10 (see FIG. 1) (step 206). When the display format information receiving unit 22 receives the display format information (Yes in step 206), the display format information holding unit 25 (see FIG. 3) updates the display format information (step 207) and holds the received display format information.

[0052] Then, the process returns to step 204. That is, the output unit 26 (see FIG. 3) creates display data for displaying the search results using the updated display format information (step 204), and outputs the created display data (step 205). Note that the display data also includes the search information used in the search.

[0053] If the display format information receiving unit 22 does not receive new display format information (No in step 206), the process ends. The timing for terminating the processing may be determined by receiving a termination instruction from the terminal 10, or by not receiving any information after a predetermined period of time has elapsed.

[0054] Next, a display example will be described in which display data output from the real estate information providing device 20 (see FIG. 1) is displayed as a search result on the terminal 10 (see the same figure). The terminal 10 has a screen 50, and the display data is displayed on the screen 50. FIG. 7 is a diagram showing an example of a display displayed on the screen 50 of the terminal 10. As shown in FIG. 7 includes a basic settings field 51, a map field 52, a map legend field 53, a target condominium information field 54, a graph field 55, and a graph legend field 56. Note that the screen 50 shows an example of display data output from the output unit 26 (see FIG. 3) of the real estate information providing device 20.

[0055] The basic setting field 51 has a tab 511 called "display condition set" and a Reset button 512. The tab 511 for the display condition set shows search information. More specifically, in the basic settings field 51, an area 51a indicating a target condominium called "Condominium A" is set as one piece of search information. The target condominium here is, for example, a condominium for which a real estate transaction is planned. The address of the target condominium in the basic settings field 51 can be obtained from the database 30. The obtained address is reflected in the display content of the map field 52. For example, the map field 52 is displayed so that the obtained address is positioned in the center of the map field 52. This displays a map of the surrounding area of ​​the target condominium.

[0056] In the basic setting field 51, an area 51b including other search information such as the age of the building, the exclusive area, the total number of units, the final price, and the distance to the station is set. In the display example of FIG. 7, the area 51b shows that the age of the building is "1990-2010" and the exclusive area is "30m 2 ~40m 2 ", total number of units "20 to 300", final price "10 million to 300 million yen", distance to station "1 minute to 15 minutes". The basic setting field 51 for the age of the building, floor area, total number of units, final price, and distance from the station may be entered by the person searching, or may be automatically entered based on information about the target condominium.

[0057] An area 51c including the distance from the set condominium is set in the basic setting field 51. In the area 51c in the display example of Fig. 7, the distance from the set condominium is "within a radius of 1,000 m."

[0058] A person viewing screen 50 can understand from areas 51a and 51c that the search population will be set to apartments located within a 1km radius of the target apartment "Apartment A." In addition, a person viewing screen 50 can also understand from area 51b that apartments in the population have been searched for based on the age of construction, etc., as shown in area 51b.

[0059] The map field 52 displays the location of the target condominium. More specifically, as described above, the map field 52 displays a map of the area surrounding the target condominium. The map field 52 can also display a mark at the location of the condominium that is the search result based on the search information.

[0060] The map legend column 53 is a column that explains the map legend, which is a mark that indicates information about the condominium or the like that is displayed in the map column 52. The map legend section 53 has an area 53a indicating the total number of units, an area 53b indicating the year of construction, and an area 53c indicating the type of apartment building.

[0061] Area 53a indicates that the total number of units is divided into "20" (less than 20), "40" (20 to less than 40), "60" (40 to less than 60), "80" (60 to less than 80), and "≧100" (80 to 100). The marks corresponding to the divided total number of units are all white circles, and the outer diameter of the circle varies depending on the total number of units. Note that because the total number of units in the apartment complexes displayed in map section 52 is 100 or less, they are divided into five areas, but if an apartment complex with a total number of units exceeding 100 is included, they will be divided into six or more areas.

[0062] Area 53b shows that the difference in age between 1992 and 2010 is displayed using a color gradation. For example, the closer to 1992 the color is, the lighter the color is, and the closer to 2010 the color is. Therefore, although the specific age is not displayed, the difference between new and old buildings can be intuitively recognized.

[0063] Area 53c shows that the condominium types are divided into set condominiums and condominiums with sales examples. As an example, set condominiums are shown with a star, and condominiums with sales examples are shown with a black circle. Condominiums with no sales examples are not marked. The search results for condominiums are displayed by dividing them into those with and without sales examples. This allows users to select information that is useful when considering the purchase price of a condominium in a planned real estate transaction.

[0064] The target condominium information field 54 is a field that shows details of the entire building of the target condominium that is displayed in the area 51 a of the basic setting field 51 . In the example shown in Figure 7, in addition to the name of the apartment building, the year of construction, structure, total number of units, floors, nearest station and minutes are written in two lines (top and bottom) from left to right. Also, in the example shown in Figure 7, it is written that the land right is ownership and not leasehold, and that the management method is daytime and not full-time resident, patrol, or unmanned.

[0065] The graph column 55 displays a graph or table (hereinafter referred to as a graph, etc.) showing the search results based on the search information. More specifically, the graph column 55 displays, for example, one of a number of predetermined types of graphs, etc. The graph column 55 may be, for example, a graph showing the change in price per tsubo over time, a graph showing the change in selling price over time, or a table listing other condominiums similar to the target condominium.

[0066] The graph legend column 56 is a column that explains the graph legend, which is the part that shows information about the elements displayed in the map column 52. In the graph legend column 56 illustrated in FIG. 7, an area 56a indicating the degree of renovation and an area 56b indicating the for sale flag are set.

[0067] Area 56a includes "01_FULL" indicating a full renovation and "02_PARTIAL" indicating a partial renovation. Area 56a also includes "03_EQUIPMENT UPDATE" indicating an equipment update renovation and "04_SURFACE RENOVATION" indicating a surface renovated renovation. Area 56a also includes "05_NONE / CLEANING" indicating no renovation, only cleaning. Additionally, the area 56a includes "06_Renovation only" indicating that renovations have been made but the details are unknown. The information included in the area 56a is an example of information regarding the implementation of construction work on the property, and also an example of whether renovations have been made and, if so, the implementation items.

[0068] Furthermore, area 56a includes "99_Residing" which indicates that the person is currently residing in the apartment. In the present embodiment, "99_Residing" is included in area 56a, but this is not limiting, and it may be displayed in an area (not shown) other than areas 56a and 56b, rather than area 56a. "99_occupied" in the area 56a is an example of residence information.

[0069] Next, a specific example of the graph field 55 on the screen 50 (see FIG. 7) will be described. Note that, although a specific example of the graph field 55 will be described below, it is also possible to display only that specific example on the screen 50 in a large size.

[0070] As an example of the graph column 55, Figure 8 shows a first graph 61 showing information about rooms that have been put up for sale in "Apartment A," a target apartment building, with the vertical axis representing the price per tsubo (10,000 yen / tsubo) and the horizontal axis representing the time axis. Note that the time axis is divided into Gregorian calendar years as shown in the upper part of first graph 61, and each year is divided into months as shown in the lower part of first graph 61. Note that in Figure 8, the months are represented as "February," "April," "June," "August," "October," and "December."

[0071] As shown in Figure 8, the "floor location" and "degree of renovation" displayed above the first graph 61 are both "all." These represent part of the search information. Therefore, real estate information is searched without being limited by the floor location, such as a high floor, a middle floor, or a low floor, and the degree of renovation is also searched without being limited by whether the property has been renovated or not, or the extent of the renovation.

[0072] 8 shows information about the sale and purchase of multiple properties in the form of a plot of the relationship between the price per tsubo and the year and month, of which properties 611, 612, 613, and 614 are indicated by symbols and will be described below. At the right end of the plot showing the property, the degree of renovation shown in area 56a (see FIG. 7) and the for sale flag shown in area 56b (see FIG. 7) are shown.

[0073] In the first example shown in FIG. 8, the displayed property 611 is located on the 14th floor and has an exclusive area of ​​30 m 2 ", indicating that the property has been fully renovated. The sales period for property 611 is from July 2022 to April 2023, and it can be seen that the sale ended in the same month (see the "Sales Ended" for the for-sale flag in area 56b (see Figure 7)). In other words, the shape on the right side of property 611 is a circle, which indicates that the property is "Sales Ended," and the pattern inside the circle indicates that the property is "01_Full." The price per tsubo for Property 611 has been reduced three times since it went on sale: in September 2022, November 2022, and March 2023. The selling price can be calculated using the exclusive area and price per tsubo.

[0074] Property 612 is located on the 9th floor, and although the floor area is not specified, it is 36m 2" and has been fully renovated. Furthermore, property 612 began selling in December 2023, and as of February 2024, sales will have ended within 30 days (see "Sales Ended (within 30 days)" in the for-sale flag in area 56b (see FIG. 7)). In other words, the drawing on the right side of property 612 is a diamond, which indicates that "Sales Ended (within 30 days)," and the pattern inside the diamond indicates that it is "01_Full." The price per tsubo for property 612 has not been reduced since it was first sold. By comparing property 612 with property 611, it can be seen that property 612 was sold at a higher price per tsubo than property 611.

[0075] Property 613 is located on the 9th floor with an exclusive area of ​​36m 2 ", meaning that there is no renovation, only cleaning. In other words, the shape on the right side of property 613 is the same circle as property 611, which indicates that it is "End of Sale," and the pattern inside the circle indicates that it is "05_None·Cleaning." Sales for property 613 began in June 2023 and ended in November of the same year. The price per tsubo has not been reduced since sales began.

[0076] Property 614 is located on the 5th floor, and although the floor area is not specified, it is 30m 2 ". Property 614 began selling in January 2024, and as of February, it was still on sale (see the "For Sale" for sale flag in area 56b (see Figure 7)). In other words, the shape on the right side of property 614 is a rectangle, which indicates that it is "For Sale." There is also no pattern within the rectangle, which indicates that it is "99_Occupied." The price per tsubo for property 614 was lowered in February. Whether or not a dwelling is in operation can be determined based on, for example, energy infrastructure projects such as electricity and gas and changes in their usage.

[0077] Here, the horizontal dashed line 610 in the first graph 61 indicates the average price per tsubo for the multiple properties plotted. The prices per tsubo higher than dashed line 610 are for properties 611 and 612 that have been fully renovated, while properties 613 and 614 that have not been fully renovated are lower than dashed line 610. It can be seen that the price per tsubo at least reflects whether or not the property has been renovated.

[0078] Figure 9 shows, as an example of graph column 55, a second graph 62 showing the sales performance of other condominiums located around the target condominium "Condominium A," with the vertical axis representing the price per tsubo (10,000 yen / tsubo) and the horizontal axis representing time, plotted for each building. The price per tsubo is the final price, and the plot position on the horizontal axis is the month in which sales ended. All or part of the search conditions are displayed in two rows, top and bottom, above the second graph 62. More specifically, the "For Sale Flag" is "All," and the "Sales End Date" is "2019 / 04 / 01 - 2024 / 03 / 31." In addition, the "Apartment Name," "Land Rights," "Management Method," "Floor Location," and "Degree of Renovation" are all "All."

[0079] The second graph 62 includes a left graph 62A and a right graph 62B arranged left and right. The left graph 62A and the right graph 62B display the same apartment names as the other apartments of "Apartment A." That is, the other apartments displayed are "Apartment B," "Apartment C," "Apartment D," and "Apartment E." A mesh pattern is added to the display area for "Apartment A." In addition, the sales end months for both the left graph 62A and the right graph 62B are "June 2022 to March 2024."

[0080] Each plot in the left graph 62A and the right graph 62B is represented by the degree of renovation shown in area 56a (see Figure 7) and the for sale flag shown in area 56b (see the same figure), making the degree of renovation and the for sale flag easy to see.

[0081] The positions of the multiple plots in the left graph 62A and the right graph 62B allow the past transaction prices of the entire condominium to be determined. To explain further, left-hand graph 62A is the result of applying a one-year interval adjustment to right-hand graph 62B. In other words, the adjusted left-hand graph 62A is based on the final prices of condominiums in the area where "Condominium A" is located, and the average values ​​for each of the two periods are calculated. The two are then compared, and the adjustment is made by multiplying the difference percentage by one of the two periods. For example, if "Condominium A" is located in Shibuya Ward, the market price can be adjusted by calculating the average final prices for 2024 and 2022 of condominiums sold in Shibuya Ward, and then multiplying the difference percentage by the final price in 2022. It should be noted that the average value referred to here may be based on real estate information retrieved by the real estate information providing device 20 using search information, or may be based on real estate information held in the database 30. As the left graph 62A is a one-year interval correction, the upper part of the second graph 62 clearly shows "Applied correction value (left graph only)" in the upper row and "One-year interval correction" in the lower row. In this case, "2022" is an example of the first period, and "2024" is an example of the second period.

[0082] Here, in the second graph 62, the dashed line 621 in the left graph 62A indicates the average price per tsubo after correction for the multiple properties plotted, and the dashed line 622 in the right graph 62B indicates the average price per tsubo for the multiple properties plotted.

[0083] Figure 10 is an example of a graph column 55, showing a third graph 63 that shows the price trends of other condominiums located around the target condominium ``Condominium A'', with the vertical axis representing price and the horizontal axis representing time, plotted for each building. All or part of the search conditions are displayed above the third graph 63, similar to the second graph 62 (see FIG. 9).

[0084] The third graph 63 includes a left graph 63A and a right graph 63B arranged left and right. The left graph 63A shows the price transition (variable units) with the vertical axis representing the price per tsubo (10,000 yen / tsubo), and the right graph 63B shows the price transition (gross) with the vertical axis representing the final price (10,000 yen). The left graph 63A and the right graph 63B show "Apartment F," "Apartment G," and "Apartment H" as other apartments in addition to "Apartment A."

[0085] As with the second graph 62 (see FIG. 9), each plot of the left graph 63A and the right graph 63B in the third graph 63 is represented by the degree of renovation shown in area 56a (see FIG. 7) and the for-sale flag shown in area 56b (see FIG. 7). This makes it easier to see the degree of renovation and the for-sale flag.

[0086] In the left graph 63A and the right graph 63B, the plots moving from left to right for each condominium property show how the price trends of each property were and how they were ultimately sold. Unlike the second graph 62 (see Figure 9), the third graph 63 plots data for each apartment property, i.e., for each room. Therefore, the third graph 63 shows two properties, "Apartment A" and "Apartment F." This allows you to understand how the prices of each property changed and how they were sold.

[0087] FIG. 11 shows, as an example of the graph column 55, a fourth table 64 listing properties similar to the target condominium "Condominium A." All or part of the search conditions are displayed above the fourth table 64, similar to the second graph 62 (see FIG. 9). Additionally, at the top of Table 4 64, "Final Price per Area" is listed as the "Sorting Index," indicating the sorting criteria for the properties arranged vertically. Also, "5" is listed as the "Top N Approximation," indicating that five properties are being displayed.

[0088] In Table 4 64, the property "Apartment A" is shown as the "Appraisal Subject" in the vertical center position. Above the "Appraisal Subject" is shown the title "Top 5 Items Above a Set Value," and below it is shown the title "Top 5 Items Below a Set Value." For each of the five properties, information corresponding to the titles "Sales Information," "Building Information," "Room Information," and "Other" is shown. Sales information includes the final unit price, final price, price reduction, sales start month, and sales period. Building information includes the apartment name, construction year, total number of units, and nearest station. Room information includes the floor location, exclusive area, layout, and degree of renovation (see area 56a in Figure 7). Other information includes the degree of renovation and a for-sale flag (see area 56b in the same figure) shown as patterned figures. This allows you to consider, for example, price while comparing the appraised "Apartment A" with properties similar to "Apartment A."

[0089] FIG. 12 is a fifth graph 65, as an example of the graph column 55, showing price trends of other condominiums located around the target condominium "Condominium A" categorized by on-sale flag. As with the second graph 62 (see FIG. 9), all or some of the search criteria are displayed above the fifth graph 65. In addition, "degree of renovation" is not "all" (see FIG. 9, for example), but "multiple values," indicating that some were not selected.

[0090] The fifth graph 65 includes four graphs arranged vertically, horizontally, namely, an upper left graph 65A, a lower left graph 65B, an upper right graph 65C, and a lower right graph 65D. The horizontal axes of upper left graph 65A, lower left graph 65B, upper right graph 65C, and lower right graph 65D are all divided by sales flag (sold out, sold out (within 30 days), and on sale). Upper left graph 65A and lower left graph 65B further divide the sales end period. In addition, the vertical axis of upper left graph 65A is the price per tsubo (10,000 yen / tsubo), the vertical axis of lower left graph 65B is the sales period (days), and the vertical axis of upper right graph 65C and lower right graph 65D is the number of cases.

[0091] In the upper left graph 65A, lower left graph 65B, upper right graph 65C, and lower right graph 65D of the fifth graph 65, the degree of renovation shown in area 56a (see FIG. 7) is displayed for each project for easy viewing.

[0092] To explain in more detail, the upper left graph 65A and the lower left graph 65B plot the end of sales dates divided into 2019, 2020, 2021, 2022, 2023, and 2024. Note that the upper left graph 65A and the lower left graph 65B show the plot for 2020, and the plots for other years are indicated by "..." and are not shown.

[0093] Additionally, graph 65A in the upper left shows an average price per tsubo of 387 when sales end in 2020. Average prices per tsubo for sales end in other years are not shown. This allows us to understand the average price level each year. We can also see fluctuations in the price per tsubo in areas such as Shibuya Ward and the surrounding area of ​​the target apartment building, Apartment A, meaning whether the price per tsubo in that area is rising or falling.

[0094] Additionally, graph 65B on the bottom left shows an average of 106 days for the sales period when the sales period ends in 2020. The average price per tsubo for sales ending in other years is not shown. This allows you to understand how many days it took on average to sell.

[0095] In the upper right graph 65C, the horizontal axis divides the properties into three categories: sold out, sold out (within 30 days), and currently on sale, and the price per tsubo (10,000 yen / tsubo) is shown for each category. The vertical axis shows the number of cases calculated by tallying the plots in the upper left graph 65A. In addition, the upper right graph 65C also shows the number of cases according to the degree of renovation, so it is possible to compare the price per tsubo focusing on the degree of renovation, for example.

[0096] In the lower right graph 65D, the horizontal axis divides the results into three categories: sold out, sold out (within 30 days), and currently on sale, and the sales period (days) for each category is also shown. The vertical axis shows the number of cases calculated by tallying the plots in the lower left graph 65B. In addition, the lower right graph 65D also shows the number of cases according to the degree of renovation, so it is possible to compare sales periods focusing on the degree of renovation, for example. Here, the dashed line 651 in the upper left graph 65A in the fifth graph 65 indicates the average price per tsubo.

[0097] It is possible to reselect the degree of renovation, for example, to display only "01_Full" in the fifth graph 65. This makes it possible for the seller and buyer to consider the price, taking into account the degree of renovation. This selection of the degree of renovation can also be performed for the first graph 61 to the fourth graph 64 described above.

[0098] On the screen 50 of the terminal 10, the display switching among the above-mentioned first graph 61, second graph 62, third graph 63, fourth table 64, and fifth graph 65, and the reselection of the degree of renovation to be displayed are performed by the display format information. Such display format information is transmitted from the terminal 10 to the real estate information providing device 20. That is, when the real estate information providing device 20 receives the display format information (see "Yes" in step 206 of FIG. 6), the display format information is updated (see step 207 of FIG. 6). Then, new display data is created (see step 204 of FIG. 6) and output to the terminal 10 (see step 205 of FIG. 6).

[0099] Although the embodiments of the present invention have been described above, the technical scope of the present invention is not limited to the scope described in the above embodiments. It is clear from the claims that various modifications and improvements to the above embodiments are also included in the technical scope of the present invention. [Explanation of symbols]
