Description

[Technical field]

[0001] The present invention relates to a real estate appraisal device that appraises real estate based on the surrounding environment. [Background technology]

[0002] Conventionally, systems for searching real estate information necessary for purchasing or renting land or buildings have been known. In such systems, a customer can input the desired area, size, layout, price, etc., and the corresponding property can be extracted. However, in general, such systems simply present existing real estate information and do not evaluate the value of real estate, which changes due to changes in the surrounding environment, etc.

[0003] On the other hand, in recent years, real estate information provision systems have been developed that allow customers to obtain the same information as if they were actually visiting the property, without actually going to see it, by using real estate information and real estate map information including three-dimensional images. Furthermore, systems that allow customers to select real estate taking into account their current living environment and future changes in the environment have also been developed.

[0004] For example, Patent Document 1 discloses a real estate information system that makes it possible to make judgments about acquired real estate from economic and legal perspectives, and to select real estate based on comprehensive information that takes into account the current living environment and future changes in the environment. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2013-149174 A Summary of the Invention [Problem to be solved by the invention]

[0006] The value of real estate can fluctuate depending on the surrounding environment, and it can be difficult for real estate agents to set the selling price or rent of real estate appropriately. Therefore, it is important to properly obtain information about the surrounding environment of the real estate and to properly evaluate the real estate based on the current and future surrounding environment.

[0007] Here, according to the system described in Patent Document 1, it is possible to obtain economic information and legal information about real estate, such as the posted price, as well as living environment map information and planned environment map information about real estate, but it is not capable of visualizing information related to real estate valuation in a centralized, user-friendly manner, nor is it capable of evaluating the overall value of real estate.

[0008] The object of the present disclosure is to provide a technology that can centrally visualize information related to real estate valuation in a user-friendly manner, and further enables comprehensive value assessment of real estate based on the surrounding environment. [Means for solving the problem]

[0009] The real estate evaluation device disclosed herein is a device for evaluating real estate based on the surrounding environment. The real estate evaluation device includes an acquisition unit that acquires environmental information that is information about the surrounding environment of the real estate, a calculation unit that calculates an evaluation coefficient of the real estate based on the environmental information, the calculation unit calculating the evaluation coefficient including a positive value evaluation and a negative value evaluation of the real estate, and an evaluation unit that evaluates a comprehensive value of the real estate based on the evaluation coefficient.

[0010] In the above real estate evaluation device, the overall value of a property is evaluated based on evaluation coefficients including positive and negative value evaluations. Therefore, real estate agents or customers who wish to purchase or lease land or buildings can properly understand each evaluation item for the property to be evaluated, and can more properly understand the overall value of the property based on the surrounding environment.

[0011] Here, in the real estate appraisal device of the present disclosure, the appraisal coefficient may include, as the positive appraisal, a recommendation level based on the distance from a predetermined facility, and, as the negative appraisal, a risk level related to earthquakes, flood damage, and land pollution. In this case, the positive appraisal may include a recommendation level based on added value of a predetermined resource and / or tourist facility in the area where the real estate is located. Also, the negative appraisal may include a risk level related to the capacity of public infrastructure based on the density of apartment buildings in the area where the real estate is located.

[0012] In addition, in the real estate appraisal device disclosed herein, the calculation unit may further calculate a road width coefficient based on the width of the road to which the real estate is adjacent, and the appraisal unit may appraise the overall value of the real estate based on the appraisal coefficient and the road width coefficient. Effect of the Invention

[0013] According to the present disclosure, information regarding real estate valuation can be visualized in a centralized manner in a user-friendly manner, and further, a comprehensive value assessment of real estate based on the surrounding environment can be made.

[0015] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The configurations of the following embodiments are merely examples, and the present disclosure is not limited to the configurations of the embodiments.

[0016] First Embodiment An overview of the information processing system in the first embodiment will be described with reference to Fig. 1. Fig. 1 is a diagram showing a schematic configuration of the information processing system in this embodiment. The information processing system 100 according to this embodiment includes a network 200, a server 300, and a user terminal 400. The information processing system 100 in this embodiment is a system for evaluating real estate based on the surrounding environment, and the processing is executed by the server 300. The user who uses the information processing system 100 in this embodiment is a real estate agent.

[0017] The network 200 is, for example, an IP network, and connects the server 300 and the user terminal 400 so that they can communicate with each other. If the network 200 is an IP network, it may be wireless, wired, or a combination of wireless and wired. For example, in the case of wireless communication, the user terminal 400 may access a wireless LAN access point (not shown) and communicate with the server 300 via a LAN or a WAN. Furthermore, the network 200 is not limited to these examples, and may be, for example, a public switched telephone network, an optical fiber line, an ADSL line, a satellite communication network, or the like, or may be related to short-distance communication such as Bluetooth (registered trademark).

[0018] The server 300 is connected to a user terminal 400 via a network 200. For ease of explanation, one server 300 and four user terminals 400 are shown in Fig. 1, but it goes without saying that the number of users is not limited to this.

[0019] The server 300 may be any electronic device having a processing capability for arithmetic processing such as data acquisition, generation, and updating, and processing, such as a personal computer, a server, a mainframe, or other electronic device. That is, the server 300 may be configured as a computer having a processor such as a CPU or GPU, a main storage device such as a RAM or ROM, and an auxiliary storage device such as an EPROM, a hard disk drive, or a removable medium. The removable medium may be, for example, a USB memory or a disk recording medium such as a CD or DVD. The auxiliary storage device stores an operating system (OS), various programs, various tables, and the like.

[0020] In addition, the server 300 may appropriately use SaaS (Software as a Service), Paas (Platform as a Service), or IaaS (Infrastructure as a Service) provided by a cloud server, without providing software, hardware, an OS, etc., dedicated to the information processing system 100 of this embodiment.

[0021] The user terminal 400 may be any electronic device such as a mobile terminal owned by a user (in this embodiment, a real estate agent) who uses the information processing system 100, and may be, for example, a mobile terminal, a tablet terminal, a smartphone, a wearable terminal, a personal computer, or other terminal device.

[0022] Next, components of the server 300 and the user terminal 400 will be mainly described in detail with reference to Fig. 2. Fig. 2 is a diagram showing in more detail the components of the server 300 and the user terminal 400 included in the information processing system 100 in the first embodiment.

[0023] The server 300 has, as functional units, a communication unit 301, a storage unit 302, and a control unit 303, and can realize functions that match the predetermined purpose of each functional unit by loading a program stored in an auxiliary storage device into a working area of ​​a main storage device and executing the program, and controlling each functional unit through the execution of the program. However, some or all of the functions may be realized by hardware circuits such as ASIC and FPGA.

[0024] Here, the communication unit 301 is a communication interface for connecting the server 300 to the network 200. The communication unit 301 includes, for example, a network interface board and a wireless communication circuit for wireless communication. The server 300 is connected to the user terminal 400 and other external devices via the communication unit 301 so as to be able to communicate with them.

[0025] The storage unit 302 includes a main storage device and an auxiliary storage device. The main storage device is a memory in which the programs executed by the control unit 303 and data used by the control programs are expanded. The auxiliary storage device is a device in which the programs executed by the control unit 303 and data used by the control programs are stored. The storage unit 302 stores environmental information, which will be described later. The storage unit 302 may also store data transmitted from the user terminal 400 or the like, and the server 300 can acquire the data transmitted from the user terminal 400 or the like via the communication unit 301.

[0026] The control unit 303 is a functional unit that manages the control performed by the server 300. The control unit 303 can be realized by an arithmetic processing device such as a CPU. The control unit 303 further includes three functional units: an acquisition unit 3031, a calculation unit 3032, and an evaluation unit 3033. Each functional unit may be realized by executing a stored program by the CPU.

[0027] The acquisition unit 3031 acquires environmental information, which is information on the surrounding environment of the real estate to be evaluated. Here, the environmental information is information that can be acquired based on the address of the real estate to be evaluated, and the acquisition unit 3031 can acquire the environmental information based on map information and facility information published by public institutions, private businesses, etc. Then, the acquisition unit 3031 stores the environmental information in the storage unit 302 of the server 300. Note that, in order to identify the real estate to be evaluated, the acquisition unit 3031 acquires the address of the real estate to be evaluated in advance from the user terminal 400 owned by the real estate agent.

[0028] Here, the user terminal 400 in this embodiment has a communication unit 401, an input / output unit 402, and a storage unit 403 as functional units. The communication unit 401 is a communication interface for connecting the user terminal 400 to the network 200, and is configured to include, for example, a network interface board and a wireless communication circuit for wireless communication. The input / output unit 402 is a functional unit for displaying information transmitted from the outside via the communication unit 401, and inputting the information when transmitting the information to the outside via the communication unit 401. The storage unit 403 is configured to include a main storage device and an auxiliary storage device, similar to the storage unit 302 of the server 300.

[0029] The input / output unit 402 further includes a display unit 4021, an operation input unit 4022, and an image / audio input / output unit 4023. The display unit 4021 has a function of displaying various information, and is realized, for example, by an LCD (Liquid Crystal Display) display, an LED (Light Emitting Diode) display, an OLED (Organic Light Emitting Diode) display, or the like. The operation input unit 4022 has a function of accepting operation input from a user, and is specifically realized by soft keys or hard keys such as a touch panel. The image / audio input / output unit 4023 has a function of accepting input of images such as still images and videos, and is specifically realized by a camera using an image sensor such as a Charged-Coupled Devices (CCD), a Metal-oxide-semiconductor (MOS), or a Complementary Metal-Oxide-Semiconductor (CMOS). The image / audio input / output unit 4023 has a function of accepting input and output of audio, and is specifically realized by a microphone or a speaker.

[0030] The real estate agent can use the user terminal 400 configured in this manner to transmit the address of the real estate to be evaluated to the server 300. Here, the server 300 may provide the user terminal 400 with an interface for inputting the above information. In this case, the real estate agent can transmit the address of the real estate to be evaluated to the server 300 by inputting information into the above interface via the user terminal 400.

[0031] The calculation unit 3032 calculates the evaluation coefficient of the real estate based on the above environmental information. Here, the evaluation coefficient of the real estate is an evaluation coefficient including a positive value evaluation and a negative value evaluation of the real estate to be evaluated. Details of the process performed by the calculation unit 3032 will be described later with reference to FIG. 3.

[0032] The positive value assessment of the above real estate may also include a recommendation based on the added value of certain resources and / or tourist facilities in the area in which the assessed real estate is located.

[0033] The negative property valuation may also include a risk to public infrastructure capacity based on the density of apartment complexes in the area in which the property is located.

[0034] The evaluation unit 3033 evaluates the overall value of the real estate based on the above evaluation coefficients calculated by the calculation unit 3032.

[0035] The evaluation unit 3033 may evaluate the overall value of the property based on a road width coefficient based on the width of the road adjacent to the property to be evaluated, in addition to the evaluation coefficient. In this case, the road width coefficient may be calculated by the calculation unit 3032.

[0036] Here, the flow of operations of the information processing system 100 in this embodiment will be described. Fig. 3 is a diagram illustrating the flow of operations of the information processing system 100 in the first embodiment. Fig. 3 describes the flow of operations between the components of the information processing system 100 in this embodiment and the processes executed by each component.

[0037] 3, first, a target address indicating the location of a property to be evaluated is input to the user terminal 400 of the real estate agent (S101). The real estate agent can input the target address using the input / output unit 402 of the user terminal 400.

[0038] The target address entered into the real estate agent's user terminal 400 is then transmitted to the server 300, which acquires this information (S102).

[0039] Next, the server 300 acquires environmental information (S103). As described above, the server 300 can acquire environmental information based on map information and facility information published by public institutions, private businesses, etc. Then, the server 300 stores the acquired environmental information in the storage unit 302.

[0040] Here, the above environmental information is, for example, information on the locations of stations, schools, parks, hospitals, government offices, post offices, financial institutions, supermarkets, convenience stores, etc. in the vicinity of the real estate to be evaluated. The above environmental information also includes, for example, information on earthquakes, flood damage, and land contamination in the vicinity of the real estate to be evaluated.

[0041] Furthermore, the above environmental information may include information regarding specific resources and / or tourist facilities in the area in which the real estate being evaluated is located, and information regarding the density of apartment buildings in the area in which the real estate being evaluated is located.

[0042] Then, the server 300 calculates an assessment coefficient for the real estate to be assessed based on the environmental information acquired in the process of S103 (S104). As described above, the assessment coefficient for real estate is a coefficient including a positive value assessment and a negative value assessment for the real estate to be assessed, and the server 300 calculates a recommendation level based on the distance from a specified facility as the positive value assessment, and calculates the risk levels of earthquakes, flood damage, and land contamination as the negative value assessment. Furthermore, in this embodiment, in addition to the above assessment coefficients, the server 300 further calculates a road width coefficient based on the width of the road adjacent to the real estate to be assessed.

[0043] FIG. 4 is a diagram showing an example of calculation of a recommendation level indicating a positive value evaluation, a risk level indicating a negative value evaluation, and a road width coefficient.

[0044] FIG. 4(a) is a diagram illustrating an example of recommendation levels based on distance from a station, where the recommendation level can be set to 0 to 5 depending on the time required to walk from the station to the real estate to be evaluated. In this embodiment, similarly, the recommendation level can be set to 0 to 5 depending on the time required to walk from a school, park, hospital, government office, post office, financial institution, supermarket, convenience store, etc. to the real estate to be evaluated. In this way, the recommendation level, which indicates a positive value evaluation, is set to a higher value the closer the distance from the above facilities is.

[0045] Moreover, Fig. 4(b) is a diagram illustrating risk levels based on the possibility of liquefaction, and the risk level can be set from 0 to 10 depending on the possibility of liquefaction in the real estate to be evaluated. In the present embodiment, similarly, the risk level can be set from 0 to 10 depending on the susceptibility of the real estate to be evaluated to shaking in the event of an earthquake, the depth of tsunami inundation, the possibility of inundation, the possibility of landslides, the possibility of soil contamination, etc. In this way, the risk level representing a negative value evaluation is set to a higher value as the risk of disasters, etc. increases.

[0046] Furthermore, FIG. 4(c) is a diagram illustrating the road width coefficient, and the coefficient can be set to recommendation level 1 to 5 or risk level 1 to 5 depending on the width of the road adjacent to the real estate to be evaluated. Here, if the width of the road adjacent to the real estate to be evaluated is too narrow, there is a risk that ambulances, fire engines, etc. cannot enter the location of the real estate. Therefore, if the width of the road adjacent to the real estate is 1m or less, the risk level is set to 5. In addition, if the width of the road adjacent to the real estate to be evaluated becomes relatively wide, the traffic volume of vehicles, etc. tends to increase. Therefore, if the width of the road adjacent to the real estate is more than 9m and less than 10m, the risk level is set to 1, if it is more than 10m and less than 11m, the risk level is set to 3, and if it is more than 11m, the risk level is set to 5. On the other hand, if the width of the road adjacent to the real estate is more than 5m and less than 6m, which is easy for ambulances, fire engines, etc. to enter and often does not fall under the category of a trunk road, the recommendation level is set to 5.

[0047] In this embodiment, in the process of S104, the server 300 further calculates a recommendation level based on the added value of certain resources and / or tourist facilities in the area where the real estate to be evaluated is located as a positive value evaluation of the real estate. Here, the above-mentioned resources are, for example, hot springs. The server 300 sets the recommendation level to 5 if the above-mentioned resources and tourist facilities are present, and sets the recommendation level to 0 if the above-mentioned resources and tourist facilities are not present.

[0048] In this embodiment, in the process of S104, the server 300 further calculates a risk level related to the capacity of the public infrastructure based on the density of apartment buildings in the area where the real estate to be evaluated is located as a negative value evaluation of the real estate. Here, in an area where apartment buildings are densely populated, for example, a situation may occur in which the rainwater treatment capacity is exceeded during heavy rain, causing sewage to back up. Therefore, the server 300 sets the risk level to 10 when the density of apartment buildings is high, and sets the risk level to 0 when the density of apartment buildings is low.

[0049] 3, the server 300 evaluates the overall value of the property based on the evaluation coefficients and road width coefficients calculated in the process of S104 (S105). In the process of S105, the server 300 calculates the sum of each value for the above evaluation coefficients and road width coefficients, with the recommendation level set as a positive value and the risk level set as a negative value. Then, based on the calculated sum, the evaluation rating is set to F to SSS. For example, the server 300 assigns an evaluation rating as follows: F if the above sum is between -70 and -61, E if it is between -60 and -51, EE if it is between -50 and -41, D if it is between -40 and -31, DD if it is between -30 and -21, C if it is between -20 and -11, CC if it is between -10 and -1, B if it is between 0 and 9, BB if it is between 10 and 19, A if it is between 20 and 29, AA if it is between 30 and 39, S if it is between 40 and 49, SS if it is between 50 and 59, and SSS if it is between 60 and 70.

[0050] Next, the server 300 visualizes the above-mentioned evaluation results (S106). The server 300 then transmits information related to the visualized evaluation results to the real estate agent's user terminal 400. The real estate agent's user terminal 400 then acquires the above-mentioned information (S107). This allows the real estate agent to centrally grasp information related to property evaluations.

[0051] Specifically, information relating to real estate valuation as shown in Fig. 5 can be viewed on the real estate agent's user terminal 400. Here, Fig. 5 is a diagram showing an example in which information relating to real estate valuation is visualized in a unified manner.

[0052] The screen SC1 illustrated in Figure 5 is displayed on the display unit 4021 of the user terminal 400, and the screen SC1 shown in Figure 5 displays a positive value assessment column SC11, a negative value assessment column SC12, a road width coefficient display column SC13, and an evaluation rating display column SC14, which is the overall value of the real estate.

[0053] By visualizing the information in this way, information on real estate valuation is visualized in a centralized and user-friendly format, allowing real estate agents or customers wishing to purchase or lease land or buildings to properly understand each evaluation item for the real estate being evaluated, as well as to more appropriately grasp the overall value of the real estate based on the surrounding environment.

[0054] According to the information processing system 100 described above, information relating to real estate evaluation can be visualized in a centralized manner in a user-friendly manner, and furthermore, a comprehensive value evaluation of real estate based on the surrounding environment becomes possible.

[0055] <Second embodiment> The information processing system 100 according to the second embodiment will be described with reference to Fig. 6. Fig. 6 is a diagram illustrating an example of the flow of operations of the information processing system 100 in this embodiment. Fig. 6 describes the flow of operations between the components of the information processing system 100 in this embodiment and the processes executed by each component.

[0056] 6, first, evaluation application information is input to the customer's user terminal 400 (S201). Here, the evaluation application information includes the customer's contact information (name, address, telephone number, email address, etc.), the address of the real estate to be evaluated, its category (land purchase / sale, condominium purchase / sale, rental, etc.), and purpose (considering purchasing a home, considering building an apartment, etc.), and the customer can input such evaluation application information using the input / output unit 402 of the user terminal 400.

[0057] The evaluation application information entered into the customer's user terminal 400 is then transmitted to the real estate agent's user terminal 400, which then acquires this information (S202).

[0058] Next, the estimate prepared by the real estate agent is input to the real estate agent's user terminal 400 (S203). This estimate is the consideration for the service provided by the real estate agent to evaluate the value of the real estate to be evaluated, and may include a payment method for the consideration. The estimate input to the real estate agent's user terminal 400 is then transmitted to the customer's user terminal 400, which acquires this information (S204).

[0059] Next, the customer's user terminal 400 executes a settlement process for the fee to be paid to the real estate agent in relation to the valuation of the real estate to be appraised by the real estate agent (S205). Note that the process of S205 may use a well-known technique.

[0060] Then, when the real estate agent's user terminal 400 acquires the above-mentioned information on completion of payment (S206), environmental information is input to the real estate agent's user terminal 400 (S207). The above-mentioned environmental information is, for example, information on the locations of stations, schools, parks, hospitals, government offices, post offices, financial institutions, supermarkets, convenience stores, etc., in the vicinity of the real estate to be evaluated, and information on earthquakes, flood damage, and land pollution in the vicinity of the real estate to be evaluated. The real estate agent can input environmental information based on this information by accessing map information and facility information made public by public institutions and private businesses.

[0061] When the server 300 acquires the environmental information input to the real estate agent's user terminal 400 and transmitted from the user terminal 400 (S208), it then calculates an evaluation coefficient for the real estate to be evaluated (S209). Note that the processing of this S209 is as described in the explanation of the processing of S104 in FIG. 3 above. The server 300 then evaluates the overall value of the real estate based on the evaluation coefficients calculated in the processing of S209 (S210). Note that the processing of this S210 is as described in the explanation of the processing of S105 in FIG. 3 above.

[0062] The evaluation coefficients calculated by the server 300 and information about the total value of the property are then transmitted to the real estate agent's user terminal 400, and the real estate agent executes a process to visualize these results (S211). Information about the visualized evaluation results is then transmitted from the real estate agent's user terminal 400 to the customer's user terminal 400, which acquires the information (S212), enabling the customer to grasp information about the evaluation of the property in a user-friendly, unified manner.

[0063] <Other Modifications> The above embodiment is merely an example, and the present disclosure may be modified as appropriate without departing from the spirit and scope of the present disclosure. For example, the processes and means described in the present disclosure may be freely combined and implemented as long as no technical contradiction occurs.

[0064] In the above embodiment, an example has been described in which the processes of the acquisition unit 3031, the calculation unit 3032, and the evaluation unit 3033 are executed by the server 300. However, these processes may be executed by the user terminal 400.

[0065] In addition, in the above embodiment, an example was described in which a real estate agent uses the information processing system 100, but a user using the information processing system of the present disclosure may also be a customer who wishes to purchase or rent land or a building.

[0066] Furthermore, the processing described as being performed by one device may be shared and executed by a plurality of devices. For example, the acquisition unit 3031 may be formed in a processing device separate from the server 300. In this case, the separate processing device is configured to be able to cooperate favorably with the server 300. Furthermore, the processing described as being performed by different devices may be executed by a single device. In a computer system, the hardware configuration (server configuration) by which each function is realized can be flexibly changed.

[0067] The present disclosure can also be realized by supplying a computer program implementing the functions described in the above embodiments to a computer, and having one or more processors of the computer read and execute the program. Such a computer program may be provided to the computer by a non-transitory computer-readable storage medium connectable to the system bus of the computer, or may be provided to the computer via a network. Non-transitory computer-readable storage media include, for example, any type of disk, such as a magnetic disk (floppy disk, hard disk drive (HDD), etc.), an optical disk (CD-ROM, DVD disk, Blu-ray disk, etc.), a read-only memory (ROM), a random access memory (RAM), an EPROM, an EEPROM, a magnetic card, a flash memory, an optical card, and any type of medium suitable for storing electronic instructions.
