[Assessed 104.3%] Detached house in Koshigaya, Saitama — 18 min from Koshigaya Sta.

A pre-owned detached house in Higashi-Koshigaya 5-chome, Koshigaya, an 18-minute walk from Koshigaya Station and a 22-minute walk from Kita-Koshigaya Station on the Tobu Isesaki Line (Tobu Skytree Line). There is also a bus route: 21 minutes by bus from Minami-Koshigaya Station on the JR Musashino Line to the Koshigaya City Library stop, then a 7-minute walk. The area is a flat residential district on the lowland along the Motoarakawa River, and the listing itself describes the site as flat with a flat walk to the station. The house is a two-story wooden 4LDK built in December 1983, with a registered floor area of 97.7 ㎡ on a registered lot of 129.19 ㎡. It is freehold with no private road burden, and the listing says it has been renovated and is available for immediate handover. It is not an income property, so no yield is listed.

The lot faces a 7.2 m wide road on the southeast, which the listing describes as having a maintained sidewalk. It is in a Category 1 medium-to-high-rise exclusive residential zone (60% building coverage, 200% floor area ratio), and the only other restriction listed is regulation under the Landscape Act. Public water, public sewer and individual LPG; there is no parking space. In the listing photos the road in front is flat as far as can be seen, and the step from the gate to the entrance porch is only a few steps. No retaining wall or high foundation is visible, and the house stands apart from both neighbors as a detached building, not a row house. ⚠️ However, the boundaries with the neighbors at the rear (northwest), northeast and southwest do not appear in any photo, so the difference in ground level with those neighbors and whether there is a retaining wall have not been confirmed. Elevation data from the Geospatial Information Authority of Japan (GSI) shows the surroundings at about 4.8–5.5 m and flat, but this is only supporting evidence.

The land is valued at the 2026 road price of 130,000 yen/㎡ (leasehold ratio D). The local streets in Higashi-Koshigaya 5-chome range from 120,000 to 135,000 yen/㎡, and because streets at 130,000 and 135,000 yen/㎡ are nearly equal in number, we adopted the lower 130,000 yen/㎡. The same route rose from 120,000 to 125,000 to 130,000 yen/㎡ over three years. The building is 42 years old and has exceeded the 22-year statutory useful life for wooden structures, so it is valued at zero. The assessed ratio is about 104.3%; at 120,000 yen/㎡ it would be about 96.3%, at 125,000 yen/㎡ about 100.3%, and at 135,000 yen/㎡ about 108.3%.

The price of 16.1 million yen is below the total road-price value of the land (130,000 yen/㎡ × 129.19 ㎡ = about 16.79 million yen). As facts, the building is a 42-year-old wooden house, there is no parking space on the lot, and the nearest station, Koshigaya, is an 18-minute walk away. Road prices are values used for inheritance tax assessment and do not match actual transaction prices.
