[Assessed 97.6%] Detached house in Kawagoe City, Saitama — 19 min from Shingashi Sta.

Sunashinden 6-chome spans three road-price sheets, but the residential blocks under the street-address system are all clustered in the south-east of sheet 26146. We geocoded blocks 1 and 5 of Sunashinden 6-chome through the Geospatial Information Authority's address search and matched them against the block numbers printed on the sheet, confirming a scale of about 0.85 m per point before fixing the location. The resulting 1.36 km straight-line distance from Shingashi Station is consistent with the listed 19-minute walk.

Road prices in this block run from 96,000 to 105,000 yen per sqm. We took 105,000 yen, the modal value along the neighbourhood roads. The adjacent sheet carries a band of 130,000 to 145,000 yen, but that belongs to the separate districts of Fujima and Fujiwara-cho, so we did not use it. Even at the cheapest figure in the neighbourhood, 96,000 yen, the ratio is 94.8 percent, and at 100,000 yen it is 96.1 percent - the choice does not change the conclusion. The three-year trend is 97,000, 100,000 and 105,000 yen.

We opened all ten listing images and checked the perimeter of the site using the two actual exterior photographs and one of the road. Working from the original 640x480 images, we also enlarged the lower half of the exterior shot twofold to examine the site frontage. The boundary with the road is a concrete kerb only; compared against the 60 cm tyre diameter of the parked kei car, its height is under 0.15 m. The two steps at the entrance porch come to about 0.3 m against a 200 cm door height. On the western boundary the ground is at much the same level on both sides, so the fence there is not retaining any earth.

On this listing site the land area is defined as the area excluding any private road, and the listing states the area was surveyed. There is no private-road burden or setback noted, and the photographs show no flagpole access strip or sloped ground. As the plot is regular and fronts the road across its full width, the listed 117.10 sqm is used in full for the assessment.

Because completion is scheduled for September 2026, the building assessment survives in full. The wood-frame replacement cost of 220,000 yen per sqm multiplied by the 107.44 sqm floor area gives about 23.64 million yen, which is 66 percent of the total assessment. The listing does not state that the floor area includes a built-in garage, and the photographs show the parking space as a level area outside the building.

The north-western half of this sheet - Sunakubo and Imafuku - is a multiplier-rate area where no road price is published, but we confirmed that the residential blocks of Sunashinden 6-chome do carry road prices and can therefore be valued this way. The leasehold-ratio symbol is D in all three years, above the E-and-below band we exclude.
