[Assessed 85.8%] Detached house in Tachikawa, Tokyo — 20 min from Tachihi Sta.

This is Unit 7 of a new eight-home development in Sakaecho 2-chome, Tachikawa, a 20-minute walk from Tachihi Station on the Tama Toshi Monorail (one SUUMO listing for the same development gives 19 minutes). Buses also serve the area: the Sakaecho Nichome stop, 15 minutes by bus from JR Tachikawa Station, is a 3-minute walk away, and the Kamibenten stop, 8 minutes by bus from Kunitachi Station on the JR Chuo Line, is a 6-minute walk away. The listing puts Tachikawa Municipal Minamisuna Elementary School 350 m away, and another listing for the same development gives LaLaport Tachikawa Tachihi as a 16-minute walk.

The house is a two-storey wooden 4LDK with a total floor area of 94.76 m² (46.57 m² on the ground floor and 48.19 m² upstairs). It is scheduled for completion in December 2026 and is not yet finished (SUUMO gives completion in November and handover in late December). The land is a freehold plot of 122.67 m² in a Category 1 Low-Rise Exclusive Residential Zone (40% building coverage, 80% floor area ratio), with parking for one car. According to the lot plan, the site meets a newly built 5 m-wide dead-end road inside the development on the north (a road under Article 42(1)(ii) of the Building Standards Act) with a frontage of about 4.0 m plus a corner cut, and widens to about 8.9 m further back; it is not a flag-shaped lot with an access strip. Kenbiya lists it as a detached rental house, but the yield and expected rent are shown as "to be determined".

The new road in front has no route price on the FY2026 route price map, so we use 235,000 yen/m², the most common value on the local streets of Sakaecho 2-chome, as the representative value. The same route rose from 210,000 to 220,000 to 235,000 yen/m² over three years. Because the house is new, the building makes up a large share of the assessment, and the combined assessed ratio is about 85.8%. Using the 240,000 yen/m² of the existing road to the east gives about 86.9%, and even the lowest local-street band in the district, 210,000 yen/m², gives about 80.5%.

⚠️ The house is not yet built, and the Kenbiya listing has no site photos. Site photos in the SUUMO listing for the same development (Towa House) show a flat, graded vacant plot level with the road in front; the concrete edging on the neighbouring boundaries appears to be under 0.5 m high, and we saw no retaining walls or stepped access. The frontage is narrow at about 4.0 m, and the site meets the road near its dead end. Distances to nearby facilities are straight-line distances from the map coordinates of the development in the SUUMO listing (OpenStreetMap).
