Below, an embodiment of a land valuation calculation device, a land valuation calculation method, and a land valuation calculation program according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited to the present embodiment.

[1. Overview]
As a company's future prospects become increasingly important when making lending decisions, there is a demand for efficiency in collateral evaluation work, and an increasing number of financial institutions are adopting the line evaluation method, which allows for simple calculation of evaluations.

However, the conventional method had a problem in that when calculating the time adjustment rate from the amount of individual changes in roadside land value in the roadside land value evaluation method, it was not possible to take into account changes in roadside land value other than the front roadside land value. For this reason, when the range of changes in roadside land value for the side of the building was large, it was possible that the validity of the evaluation amount could not be guaranteed.

In this embodiment, for example, a time correction rate table is added that stores the road value time correction rate for each route (line), and further, by improving the timing of adding the time correction rate, it is possible to take into account not only the road value of the front, but also the road values of the side and back, etc., when calculating the land valuation. This makes it possible to efficiently calculate a more precise land valuation. The specific configuration and operation are explained below.

2. Configuration
An example of the configuration of the land evaluation value calculation device 100 according to this embodiment will be described with reference to Fig. 1. Fig. 1 is a block diagram showing an example of the configuration of the land evaluation value calculation device 100.

The land valuation calculation device 100 is a commercially available desktop personal computer. The land valuation calculation device 100 is not limited to a stationary information processing device such as a desktop personal computer, but may be a portable information processing device such as a commercially available notebook personal computer, PDA (Personal Digital Assistant), smartphone, or tablet personal computer.

The land valuation calculation device 100 includes a control unit 102, a communication interface unit 104, a memory unit 106, and an input/output interface unit 108. Each unit of the land valuation calculation device 100 is connected to each other so as to be able to communicate with each other via any communication path.

The communication interface unit 104 communicatively connects the land valuation calculation device 100 to the network 300 via a communication device such as a router and a wired or wireless communication line such as a dedicated line. The communication interface unit 104 has a function of communicating data with other devices via the communication line. Here, the network 300 has a function of connecting the land valuation calculation device 100 and the server 200 so that they can communicate with each other, and is, for example, the Internet or a LAN (Local Area Network). Note that data such as various masters described below may be stored in the server 200, for example.

An input device 112 and an output device 114 are connected to the input/output interface unit 108. The output device 114 may be a monitor (including a home television), a speaker, or a printer. The input device 112 may be a keyboard, a mouse, a microphone, or a monitor that works with a mouse to provide a pointing device function. In the following, the output device 114 may be referred to as the monitor 114, and the input device 112 may be referred to as the keyboard 112 or the mouse 112.

The storage unit 106 stores various databases, tables, files, and the like. The storage unit 106 records computer programs that work in cooperation with the OS (Operating System) to give instructions to the CPU (Central Processing Unit) to perform various processes. The storage unit 106 can be, for example, a memory device such as a RAM (Random Access Memory) or a ROM (Read Only Memory), a fixed disk device such as a hard disk, a flexible disk, an optical disk, or the like.

The memory unit 106 includes, for example, a route price table 106a and a time correction rate table 106b.

Here, roadside land value refers to the standard amount for the assessed value of land, etc., which is published annually by the National Tax Agency for private land nationwide in order to facilitate the filing of inheritance tax returns and ensure fair taxation. Roadside land value is determined for each road (direction). For example, in the land to be assessed shown in Figure 2 (type: corner lot, roadside land value year: 2019, assessment date: 1 October 2019), the roadside land value of road (A) is 350,000 yen, and the roadside land value of road (B) is 300,000 yen. The road with the higher roadside land value is called the front road, and the road with the lower roadside land value is called the side road. In the example in Figure 2, (A) is the front road, and (B) is the side road.

The route price table 106a is a table that includes route prices set for each route, district, and year. In the route price table 106a shown in FIG. 3, the route price key is a key set for each route (type) and district. The "A" key corresponds to the route "main route" and district category "highly commercial district," and the "B" key corresponds to the route "side route" and district category "highly commercial district."

Referring to the route price table 106a in FIG. 3, the route price is set at 350,000 yen for the route "Main route", the district classification "High-level commercial district", and the fiscal year 2019, the route price is set at 350,000 yen for the route "Main route", the district classification "High-level commercial district", and the fiscal year 2018, the route price is set at 300,000 yen for the route "Side route", the district classification "High-level commercial district", and the fiscal year 2019, and the route price is set at 200,000 yen for the route "Side route", the district classification "High-level commercial district", and the fiscal year 2018.

The time correction rate table 106b is a table that includes time correction rates set for each line, district, and year. Referring to the time correction rate table 106b in FIG. 5, for the line "Main Line", district "Highly Commercial District", and fiscal year 2019, the time correction rate is set to 100.00%, as shown in the row identified by the key "A", and for the line "Side Line", district "Highly Commercial District", and fiscal year 2019, the time correction rate is set to 125.00%, as shown in the row identified by the key "B". In this way, two or more time correction rates are set in the time correction rate table 106b, and it is preferable that the two or more time correction rates set are for the same district and year but different lines.

A time adjustment is a price adjustment that takes into account the fluctuation in value of the land being evaluated over time. The time adjustment rate is the rate used when making the time adjustment. The time adjustment rate will be explained using the time adjustment rate table 106b in FIG. 5 as an example. For the row identified by the key "A" in the time adjustment rate table 106b in FIG. 5 (the row corresponding to the front line), the previous year's line price is 350,000 yen and the current year's line price is also 350,000 yen, so the monthly fluctuation rate is 0.00% and the time adjustment rate is 100.00% (no change). In contrast, for the row identified by the key "B" in the time adjustment rate table 106b in FIG. 5 (the row corresponding to the side line), the previous year's line price is 200,000 yen and the current year's line price is 300,000 yen, so the monthly fluctuation rate is 12.5% and the time adjustment rate is 125.00% (changes). A feature of this embodiment is that it is possible to set the time correction rate not only for the main route but also for the side route.

The control unit 102 is a CPU or the like that provides overall control of the land valuation calculation device 100. The control unit 102 has an internal memory for storing control programs such as an OS, programs that define various processing procedures, and required data, and executes various information processing operations based on these stored programs.

The control unit 102, in terms of its functional concept, comprises, for example, (1) an acquisition unit 102a as an acquisition means for acquiring the route price and time correction rate associated with the specified route and district division and the specified year to be evaluated for the land to be evaluated from a route price table including route prices set for each route, district division, and year and a time correction rate table including time correction rates set for each route, district division, and year; (2) a pre-correction route price calculation unit 102b as a pre-correction route price calculation means for calculating the pre-correction route price per unit area for the specified route and district division based on the route price and time correction rate acquired by the acquisition means; and (3) a predetermined calculation unit 102c as a pre-correction route price calculation unit for calculating the pre-correction route price per unit area for the specified route and district division calculated by the pre-correction route price calculation unit. (4) a unit land valuation calculation unit 102d as a unit land valuation calculation means for calculating the land valuation per unit area of the land to be evaluated by adding up the corrected line prices per unit area of the specified line and each district division calculated by the corrected line price calculation means; and (5) a land valuation calculation unit 102e as a land valuation calculation means for calculating the land valuation per unit area of the land to be evaluated by multiplying the land valuation per unit area calculated by the unit land valuation calculation means by the area of the land to be evaluated. Details of the processing performed by each unit will be described in [3. Specific examples of processing] below.

3. Specific examples of processing
In this section, a specific example of the process according to the present embodiment will be mainly described. First, a conventional calculation example of land valuation will be described in [3-1] for comparison, and then a calculation example of land valuation in the present embodiment will be described in [3-2].

[3-1. Examples of conventional land valuation calculations]
First, a conventional calculation example of land appraisal value will be described with reference to FIG.

First, as shown in Figure 4, the pre-adjustment road price for the route type "front road" and district classification "high-level commercial district" is 350,000 yen/square meter, and the pre-adjustment road price for the route type "side road" and district classification "high-level commercial district" is 300,000 yen/square meter. In this case, calculations are performed taking into account certain adjustment factors (depth price adjustment, route influence addition, route weighted average, narrow frontage adjustment, large depth adjustment, etc.), and the post-adjustment road price for the route type "front road" and district classification "high-level commercial district" is calculated to be 350,000 yen/square meter, and the post-adjustment road price for the route type "side road" and district classification "high-level commercial district" is calculated to be 29,400 yen/square meter.

Next, as shown in Figure 4, the calculated adjusted route price of 350,000 yen/m2 and 29,400 yen/m2 are added together to arrive at 379,400 yen, which is the total amount, and multiplied by cliff land adjustment of 1, road width of 1, built-up land depreciation of 1, and time correction rate for the frontage route of 1 to arrive at the land valuation per unit area (1 square meter), which is 379,400 yen. Then, by multiplying the calculated 379,400 yen by the land area of 200 square meters, 75,880,000 is calculated.

In this way, the conventional method was characterized by calculating the land valuation value using only the time correction rate for the front road (i.e. not using the time correction rate for the side road). For this reason, when there was a large fluctuation in the road value for the side road, etc., there was a possibility that the validity of the valuation value could not be guaranteed.

[3-2. Example of calculation of land valuation in this embodiment]
Next, an example of calculation of land valuation in this embodiment will be described with reference to Figures 3 and 5. In this section, it is assumed that the route price table 106a is preset with the contents shown in Figure 3, and the time correction rate table 106b is preset with the contents shown in Figure 5.

(1) Acquisition process The acquisition unit 102a acquires the route price and time adjustment rate linked to the specified route and district division for the land to be evaluated, as well as the specified year to be evaluated, from the route price table 106a and the time adjustment rate table 106b.

Specifically, the operator specifies the line type "main line", the district classification "high-level commercial district", and the evaluation year "2019" as information corresponding to the line price key of "A", and the line type "side line", the district classification "high-level commercial district", and the evaluation year "2019" as information corresponding to the line price key of "B". In this case, the acquisition unit 102a acquires 350,000 yen as the line price linked to the line price key of "A" and "2019" from the line price table 106a in Fig. 3, and also acquires 100.00% as the time correction rate linked to the line price key of "A" and "2019" from the time correction rate table 106b in Fig. 5. The acquisition unit 102a also acquires 300,000 yen as the line price linked to the line price key of "B" and "2019" from the line price table 106a in FIG. 3, and acquires 125.00% as the time adjustment rate linked to the line price key of "B" and "2019" from the time adjustment rate table 106b in FIG. 5.

(2) Pre-correction route price calculation process Next, the pre-correction route price calculation unit 102b calculates the pre-correction route price per unit area for the specified route and district division based on the route price and time correction rate acquired by the acquisition unit 102a.

Specifically, the route price and time correction rate acquired by the acquisition unit 102a in (1) for the route type "main route" and the district classification "high-level commercial district" are 350,000 yen and 100.00%, respectively, so the pre-correction route price calculation unit 102b calculates the pre-correction route price per unit area (1 square meter) for the route type "main route" and district classification "high-level commercial district" as 350,000 yen x 100.00% = 350,000 yen. The calculation result is shown as the route price (after time correction) in Figure 5.

In addition, since the route price and time correction rate acquired by the acquisition unit 102a in (1) for the route type "side route" and the district classification "high-level commercial district" are 300,000 yen and 125.00%, respectively, the pre-correction route price calculation unit 102b calculates the pre-correction route price per unit area (1 square meter) for the route type "side route" and district classification "high-level commercial district" as 300,000 yen x 125.00% = 375,000 yen. The calculation result is shown as the route price (after time correction) in Figure 5.

As described above, this embodiment is characterized in that not only the time correction rate of 100.00% for the "front road" but also the time correction rate of 125.00% for the "side road" can be used in the calculation. This ensures the validity of the assessed value even when there is a large fluctuation in the road value of the side road, etc.

In addition, in this embodiment, instead of multiplying the total amount by the time adjustment rate as in the conventional example described in [3-1], one of the features is that the starting route price is multiplied by the time adjustment rate. In short, in this embodiment, the timing of using the time adjustment rate has been changed.

(3) Corrected route price calculation process Next, the corrected route price calculation unit 102c calculates the corrected route price per unit area for the specified route and district division by performing a calculation taking into account predetermined correction factors on the pre-corrected route price per unit area for the specified route and district division calculated by the pre-corrected route price calculation unit 102b.

Specifically, the pre-correction route price calculation unit 102b calculates the pre-correction route price per unit area (1 square meter) for the route type "front route" and the district classification "high-level commercial district" in (2) as 350,000 yen. The corrected route price calculation unit 102c calculates the corrected route price per unit area (1 square meter) for the route type "front route" and the district classification "high-level commercial district" as 350,000 yen by performing a calculation taking into account the predetermined correction factors (depth price correction, route influence addition, route weighted average, narrow frontage correction, large depth correction, etc.). The calculation result is shown as route price (yen/ ^m2 ) in Figure 5.

The pre-correction route price calculation unit 102b calculates the pre-correction route price per unit area (1 square meter) for the route type "side route" and the district classification "high-level commercial district" in (2) as 375,000 yen. The corrected route price calculation unit 102c calculates the corrected route price per unit area (1 square meter) for the route type "side route" and the district classification "high-level commercial district" as 36,750 yen by performing a calculation that takes into account the predetermined correction factors (depth price correction, route influence addition, route weighted average, narrow frontage correction, large depth correction, etc.) on the 375,000 yen, specifically, 375,000 yen x 0.98 x 0.1. The calculation result is shown as route price (yen/ ^m2 ) in Figure 5.

(4) Unit land valuation calculation process The unit land valuation calculation unit 102d calculates the land valuation per unit area for the land to be evaluated by adding up the corrected route prices per unit area for the specified routes and district divisions calculated by the corrected route price calculation unit 102c.

Specifically, the corrected route price calculation unit 102c calculates in (3) the corrected route price per unit area (1 square meter) for the route type "main line" and the district classification "high-level commercial district" is 350,000 yen, and the corrected route price per unit area (1 square meter) for the route type "side line" and the district classification "high-level commercial district" is 36,750 yen. Therefore, the unit land valuation calculation unit 102d adds up the 350,000 yen and the 36,750 yen to calculate the land valuation per unit area (1 square meter) for the land to be evaluated as 386,750 yen. The calculation result is shown as "Evaluated route price (1) + (2)" in Figure 5.

(5) Land valuation calculation processing Finally, the land valuation calculation unit 102e calculates the land valuation of the land to be evaluated by multiplying the land valuation per unit area calculated by the unit land valuation calculation unit 102d by the area of the land to be evaluated.

Specifically, the land valuation value per unit area (1 square meter) of the land to be evaluated calculated by the unit land valuation value calculation unit 102d in (4) is 386,750 yen. If the area of the land to be evaluated is 200 square meters, the land valuation value calculation unit 102e calculates the final land valuation value of the land to be evaluated as 386,750 yen x 200 = 77,350,000. The result of this calculation is shown as the land valuation value in Figure 5.

In this embodiment, as explained in the last paragraph of (2), the starting route price is multiplied by the time adjustment rate, so the total land valuation of 386,750 yen is not multiplied by the time adjustment rate. This is shown in Figure 5 by striking out the time adjustment rate and its value (1.00).

[4. Summary of the present embodiment]
As described above, the land valuation calculation device 100 according to this embodiment can calculate a more precise land valuation by using the time correction rate for each route.
