Abstract
Description
[Technical field]
[0001] The present invention relates to a home appraisal system for appraising a home. [Background technology]
[0002] In the used home sales market, the selling price is determined taking into consideration the number of years since the house was built and the area, but in many cases it is determined based on the value of the land. For this reason, it is difficult to say that the value of used homes is being properly evaluated, and technology to properly evaluate used homes has been studied (for example, Patent Document 1).
[0003] Patent Document 1 describes a housing information management system. This housing management system is configured to store housing history information such as housing information at the time of completion, subsequent inspection information, repair information, and extension / renovation information, and to evaluate a house based on the stored housing history information when a request to sell the house is made. [Prior art documents] [Patent documents]
[0004] [Patent Document 1] JP 2001-167156 A Summary of the Invention [Problem to be solved by the invention]
[0005] It is said that it is better to inspect and repair a house regularly even if no deterioration or damage has occurred, rather than repairing it after it has deteriorated or been damaged. This is because it can prevent serious deterioration or damage from occurring, and minimize deterioration or damage even if it has occurred. In the housing information management system described in Patent Document 1, the price of the house is evaluated based on the contents described in the housing history file as shown in FIG. 2 of Patent Document 1 and the contents described in the inspection result report as shown in FIG. 4 of Patent Document 1. For this reason, it is not possible to determine whether repairs have been performed in advance, and it is difficult to say that the house can be appropriately evaluated.
[0006] Therefore, there is a need for a home appraisal system that can appropriately assess the value of a home. [Means for solving the problem]
[0007] A characteristic configuration of the home appraisal system of the present invention is a home value calculation system that calculates the value of a home based on maintenance information related to maintenance including at least one of home inspection, home repair, and extension or remodeling of the home, and is equipped with an image information receiving unit that receives as image information an image showing the state of the home at the time of the maintenance, which is associated with identification information that can identify the home, a document information receiving unit that receives as document information a document related to the maintenance, which is associated with the identification information, an audio information receiving unit that receives as audio information a voice related to the maintenance, which is associated with the identification information, a memory unit that stores the image information, the document information, and the audio information, an identification information receiving unit that accepts the identification information of the home whose value is to be calculated, a home value calculation unit that extracts the image information, the document information, and the audio information associated with the identification information from the memory unit based on the received identification information, and calculates the value of the home based on the extracted image information, the document information, and the audio information, and an appraisal report creation unit that creates an appraisal report including the calculated value of the home.
[0008] With this characteristic configuration, image information, document information, and audio information related to the maintenance of the house can be stored in the storage unit, and the image information, document information, and audio information can be used when calculating the value of the house. Therefore, it is possible to properly create an appraisal document including the value of the house. Furthermore, by using the image information, document information, and audio information to evaluate the value of the house in this way, it is possible to properly perform the appraisal without variation in the evaluation criteria.
[0009] It is also preferable that the image information includes captured images of the state of the house before and after the maintenance.
[0010] With this configuration, the deterioration of the house can be evaluated using images taken before maintenance, and the maintenance of the house can be evaluated using images taken after maintenance. Therefore, the value of the house can be calculated taking into account the deterioration and maintenance, making it possible to more appropriately calculate the value of the house.
[0011] It is also preferable that the document information includes a document describing the costs required for the maintenance.
[0012] With this configuration, the extent of deterioration and maintenance of the house can be evaluated based on the estimate or invoice that lists the cost of maintenance. In addition, the value of the house can be evaluated after understanding the grade of materials used in the maintenance. Therefore, it is possible to more appropriately calculate the value of the house from the perspective of the materials used in the maintenance.
[0013] It is also preferable that the audio information includes audio recording of a conversation between at least two of the client who requested the maintenance, the recipient who accepted the maintenance, and the contractor who performed the maintenance.
[0014] With this configuration, recorded voice of a conversation regarding maintenance can be used to estimate the status of maintenance.
[0015] It is also preferable that the house value calculation unit uses the maintenance information to calculate repair prediction information indicating future repairs that will be required, and calculates the value of the house based on the repair prediction information.
[0016] For example, if maintenance has been performed appropriately in the past, future repair costs tend to be low, whereas if maintenance has not been performed much, future repair costs tend to be high. Therefore, with this configuration, it becomes possible to more appropriately calculate the current value of the home by estimating the costs required for future repairs.

[0018] The home evaluation system according to the present invention is configured to be able to calculate the value of a home. The home evaluation system 1 of this embodiment will be described below. However, the home evaluation system 1 is not limited to the following embodiment, and various modifications are possible without departing from the gist of the system.
[0019] The home evaluation system 1 calculates the value of a home based on maintenance information related to home maintenance, which includes at least one of home inspection, home repair, and home expansion / renovation.
[0020] A dwelling is a part of a completely partitioned building, such as a detached house or an apartment, that is constructed or remodeled so that a single household can live independently. Therefore, it includes not only a private house built for the purpose of living, but also a multi-purpose house that is connected to a part equipped with facilities for business (for example, a shop, restaurant, clinic, etc.). It is not limited to a house where people live all the time, but also includes a villa that is usually unoccupied.
[0021] Such houses are inspected periodically and repairs may be made based on the results of the inspections. The parts that are inspected include, for example, the structure, roof, exterior walls, balconies, fixtures, interior, and housing equipment.
[0022] Specifically, structural inspections check for changes to the foundation and structure over time, while roof inspections check for scratches, misalignments, and cracks in roofing materials. Exterior wall inspections check for cracks, and balconies check for leaks. Fixture inspections check the operation of doors, sashes, shutters, etc., indoor inspections check for deterioration and damage to flooring materials (wooden flooring, tatami mats, etc.) and interior walls, and housing equipment inspections check for leaks in water supply and hot water equipment and drainage equipment.
[0023] Repairs are carried out as necessary based on the results of the above-mentioned inspections, and include, for example, periodic anti-termite treatment of the structure and surface treatment (painting, etc.) of roofing materials and exterior walls. Furthermore, depending on the house, extensions and renovations may be carried out to increase or decrease the number of plots or the size of rooms.
[0024] In the home evaluation system 1, such home inspections, home repairs, and home extensions and renovations are collectively treated as home maintenance, and information relating to such maintenance is treated as maintenance information.
[0025] Fig. 1 is a block diagram showing a schematic configuration of a home appraisal system 1. As shown in Fig. 1, the home appraisal system 1 is configured to include an image information receiving unit 10, a document information receiving unit 15, an audio information receiving unit 20, a storage unit 25, an identification information receiving unit 30, a home value calculation unit 35, and an appraisal report creation unit 40. Each of these functional units is constructed of hardware or software, or both, with a CPU as a core component, in order to perform processing related to home appraisal.
[0026] The image information receiving unit 10 receives, as image information, images related to maintenance associated with identification information that can identify a house. Identification information that can identify a house is information that is assigned to identify each house among the multiple houses managed by the house evaluation system 1. Such identification information can be composed of multiple alphanumeric characters, for example. Images related to maintenance correspond to images related to the above-mentioned house inspections, house repairs, and house extensions and renovations. Therefore, the image information receiving unit 10 receives, as image information, images related to house inspections, house repairs, and house extensions and renovations associated with information that is assigned to identify each house among the multiple houses managed by the house evaluation system 1.
[0027] The image related to the image information received by the image information receiving unit 10 may be an image printed on paper (e.g., photographic paper) or may be electronic data that can be displayed on a display device. When the image information receiving unit 10 receives an image printed on paper, it is preferable to configure the unit 10 to receive data obtained by scanning the paper.
[0028] Such image information includes captured images of the state of the house before and after the maintenance. That is, captured images of the state before the inspection of the house, captured images of the state after the inspection of the house, captured images of the state before the repair of the house, captured images of the state after the repair of the house, captured images of the state before the extension or remodeling of the house, and captured images of the state after the extension or remodeling of the house are included. FIG. 2 shows a captured image G of a crack C of the exterior wall OW of the house as an example of a captured image before the maintenance. FIG. 3 shows a captured image G of a state after the crack C of the exterior wall OW of the house shown in FIG. 2 is repaired as an example of a captured image after the maintenance. In FIG. 3, the crack C after the repair is shown by a dashed line, and the repaired area is surrounded by a dashed line. Such captured images are captured by, for example, a camera, and transmitted to the image information receiving unit 10 via a media or a network, and are received by the image information receiving unit 10.
[0029] Returning to Fig. 1, the document information receiving unit 15 receives documents related to maintenance associated with the identification information as document information. Documents related to maintenance correspond to the above-mentioned documents related to home inspections, home repairs, and home extensions and renovations. Therefore, the document information receiving unit 15 receives documents related to home inspections, home repairs, and home extensions and renovations as document information associated with information assigned to identify each home among the multiple homes managed by the home evaluation system 1.
[0030] The document related to the document information accepted by the document information accepting unit 15 may be a document printed on paper, or may be electronic data that can be displayed on a display device, for example. When the document information accepting unit 15 accepts a document printed on paper, it is preferable to configure the unit 15 to accept data obtained by scanning the paper.
[0031] Such document information includes documents describing the costs required for maintenance. That is, the document information includes an estimate describing the inspection costs issued before the home inspection, an invoice describing the inspection costs issued after the home inspection, an estimate describing the repair costs issued before the home repair, an invoice describing the repair costs issued after the home repair, an estimate describing the cost of the extension / remodeling issued before the home expansion / remodeling, and an invoice describing the cost of the extension / remodeling issued after the home expansion / remodeling. FIG. 4 shows an estimate describing the repair costs issued before the home repair as an example of document information before maintenance. FIG. 5 shows an invoice describing the repair costs issued after the home repair.
[0032] Returning to Fig. 1, the voice information receiving unit 20 receives, as voice information, voice related to maintenance associated with the identification information. Voice related to maintenance corresponds to the above-mentioned voice related to home inspection, home repair, and home extension / renovation. Therefore, the voice information receiving unit 20 receives, as voice information, voice related to home inspection, home repair, and home extension / renovation associated with information assigned to identify each home among the multiple homes managed by the home evaluation system 1.
[0033] The voice related to the voice information received by the voice information receiving unit 20 may be, for example, a recorded voice of a conversation on a telephone or the like, or may be, for example, a voice recorded by a computer. It is preferable to configure the unit 20 to receive such voice as voice data.
[0034] Such voice information includes voice recordings of conversations between at least two of the client who requested the maintenance, the receiver who accepted the maintenance, and the contractor who performed the maintenance. That is, the voice recordings of conversations between the client and the receiver when providing guidance for the maintenance, the voice recordings of conversations between the client and the receiver when accepting the maintenance, and the voice recordings of conversations between the receiver and the contractor when performing the maintenance are included. Of course, the voice recordings of conversations between the client, the receiver, and the contractor are also included. FIG. 6 shows an image of the voice (voice file) of the conversation recorded when providing guidance for a home inspection as an example of voice information before the maintenance. FIG. 7 shows an image of the voice (voice data) of the conversation recorded when receiving a request for repairs in response to the inspection.
[0035] In addition, such maintenance notices and acceptances may be sent via e-mail or chat, and the contents of such e-mail or chat may be treated as document information or as silent audio information.
[0036] Returning to FIG. 1, the storage unit 25 stores image information, document information, and audio information. The image information is transmitted from the image information receiving unit 10 described above via a network. The document information is transmitted from the document information receiving unit 15 described above via a network. The audio information is transmitted from the audio information receiving unit 20 described above via a network. As described above, the image information, document information, and audio information are associated with the identification information of the house, and the storage unit 25 stores the image information, document information, and audio information in an associated state. In addition, since past image information, document information, and audio information are also used to calculate the value of the house, it is preferable to configure the storage unit 25 so that the image information, document information, and audio information are not erased until the house is demolished, for example.
[0037] The identification information receiving unit 30 receives the identification information of a house whose value is to be calculated. A house whose value is to be calculated is a house whose value is to be calculated by the house evaluation system 1. Meanwhile, as described above, a house handled by the house evaluation system 1 is associated with identification information. Therefore, the identification information receiving unit 30 receives a house whose value is to be calculated by the identification information associated with the house. Such identification information can be configured to be received, for example, via input to an input device (e.g., a keyboard or a touch panel) provided in the house evaluation system 1, or can be configured to be received via input to a terminal (e.g., a computer or a smartphone) different from the house evaluation system 1. The identification information received by the identification information receiving unit 30 is transmitted to a house value calculation unit 35 described later.
[0038] Based on the received identification information, the home value calculation unit 35 extracts image information, document information, and audio information associated with the identification information from the storage unit 25. The received identification information is the identification information received by the identification information receiving unit 30. The home value calculation unit 35 extracts all image information, document information, and audio information associated with the received identification information from the image information, document information, and audio information stored in the storage unit 25. Note that at this time, the image information, document information, and audio information are simply extracted from the storage unit 25, but are not erased.
[0039] The house value calculation unit 35 calculates the value of the house based on the extracted image information, document information, and audio information. As described above, the extracted image information includes captured images of the state of the house before inspection, captured images of the state of the house after inspection, captured images of the state of the house before repair, captured images of the state of the house after repair, captured images of the state of the house before extension or remodeling, and captured images of the state of the house after extension or remodeling.
[0040] The frequency of inspections can be estimated by the captured images of the state of the house before inspection and the state of the house after inspection. The degree of deterioration can be estimated by the captured images of the state of the house before inspection and the state of the house before repair. The part and scale (scope) of the repair, and the state of the repair (whether or not it has been completely repaired) can be estimated by the captured images of the state of the house before repair and the captured images of the state of the house after repair. Furthermore, it is possible to determine whether or not the housing equipment has been replaced. The captured images of the state of the house before extension or remodeling and the captured images of the state of the house after extension or remodeling can be used to estimate whether extension or remodeling has been performed (extension or remodeling state), for example, taking into consideration the strength of the frame and walls.
[0041] The document information also includes estimates issued before the home inspection showing the inspection costs, invoices issued after the home inspection showing the inspection costs, estimates issued before the home repairs showing the repair costs, invoices issued after the home repairs showing the repair costs, estimates issued before the home expansion / remodeling showing the expansion / remodeling costs, and invoices issued after the home expansion / remodeling showing the expansion / remodeling costs. From these estimates and invoices, it is possible to ascertain, for example, whether the work was carried out as proposed by the contractor and the grade of the housing equipment, etc.
[0042] The audio information also includes audio recordings of conversations between the requester and the receptionist when providing maintenance information, audio recordings of conversations between the requester and the receptionist when accepting maintenance, and audio recordings of conversations between the receptionist and the performer when performing maintenance. From these audio recordings, it is possible to ascertain, for example, the contents of maintenance that are not shown (missed) in the image information or document information.
[0043] Based on this information, the house value calculation unit 35 calculates the current value of the house. The value of the house may be, for example, the selling price to a housing developer in the event that the house is sold, or may be the selling price when the housing developer further sells the house.
[0044] Furthermore, the home value calculation unit 35 may use the maintenance information to calculate repair prediction information for future repairs, and calculate the value of the home based on the repair prediction information. That is, parts and home equipment that will need repairs in the future can be predicted from the extracted image information, document information, and voice information. For this prediction, it is preferable to refer to the estimated replacement time announced by the equipment manufacturer, for example. Such information predicting the parts and home equipment that will need repair corresponds to the repair prediction information. It is preferable to calculate the cost required for repairs based on this repair prediction information, and calculate the value of the home by taking this cost into account. This makes it possible to know the extent of the cost required for repairs in the future, and therefore to appropriately evaluate the value of the home. Note that the repair prediction information is preferably automatically output by storing the past repair history as big data in the storage unit 25, and inputting the image information, document information, and voice information into a learned model constructed by machine learning of artificial intelligence using this big data.
[0045] The appraisal report creation unit 40 creates an appraisal report including the calculated value of the house, as shown in Fig. 8. The value of the house calculated by the house value calculation unit 35 is transmitted to the appraisal report creation unit 40 together with the identification information. The appraisal report creation unit 40 creates an appraisal report including, for example, a captured image showing the reason why the value was determined as such, together with the house value. In addition, parts and home equipment that need to be replaced or repaired in the future may be listed, and the estimated costs for replacement or repair may be recorded.
[0046] Other embodiments In the above embodiment, the image information is described as including captured images of the state of the house before and after the maintenance. However, the image information may be configured to include captured images of the state of the house either before or after the maintenance.
[0047] In the above embodiment, the document information is described as including a document describing the maintenance costs. However, the document information may be configured not to include a document describing the maintenance costs. In this case, the home evaluation system 1 may be configured to acquire the maintenance costs in a different form. Specifically, for example, the maintenance costs may be acquired via a captured image.
[0048] In the above embodiment, the voice information is described as including a recorded voice of a conversation between at least two of the client who requested the maintenance, the receiver who accepted the maintenance, and the contractor who performed the maintenance. However, the voice information can also be configured to include a recorded voice of a conversation between the client who requested the maintenance, the receiver who accepted the maintenance, and another person (e.g., a person in charge of a government office who accepts a prescribed written application) different from the contractor who performed the maintenance.
[0049] In the above embodiment, the home value calculation unit 35 is described as calculating repair prediction information for future repairs required using maintenance information, and calculating the value of the home based on the repair prediction information. However, the home value calculation unit 35 can also be configured to calculate the value of the home without using the repair prediction information. [Industrial Applicability]
[0050] The present invention can be used in a home appraisal system for appraising the value of a home. [Explanation of symbols]
