[Assessed 92.4%] Detached house in Nagareyama, Chiba — 5 min from Heiwadai Sta.

A newly built detached house in Oaza Nishihirai, Nagareyama, Chiba. It is a 5-minute walk from Heiwadai Station on the Ryutetsu Nagareyama Line, 13 minutes on foot from Nagareyama Station and 18 minutes from Nagareyama-centralpark Station on the Tsukuba Express. The zoning is Category 1 Residential (building coverage 60%, floor area ratio 200%) within Height District Class 2. According to the SUUMO listing, Matsumoto Kiyoshi Nishihirai is 333m away, York Mart Heiwadai 532m and Ministop Nagareyama Heiwadai 712m.

This is Unit A of a two-unit development, priced at JPY 39.9 million. It is a three-storey wooden house (siding exterior, asphalt shingle roof) with 3LDK plus a storage room, completed in early September 2026. The 74.86㎡ plot is freehold with no private road burden and faces a 5m-wide paved public road on the north. A culverted waterway about 1.8m wide runs along the south side, but it lies outside the plot and is not included in the land area. The building has 109.81㎡ of floor area, seismic grade 3, design and construction performance evaluation certificates, and ZEH-level insulation. Unit B in the same development (JPY 42.9 million, land 75.77㎡, building 110.02㎡) is a separate plot; all figures here are for Unit A only. The yield is not yet set and no rent assumption is listed.

For the road price we used the FY2026 value of JPY 170,000/㎡ (leasehold ratio D) on the east-west block road near the plot. The same road was JPY 130,000 in 2024, JPY 150,000 in 2025 and JPY 170,000 in 2026, a rise of 30.8% in two years. Even with the nearby roads at JPY 160,000-165,000/㎡, the assessed ratio would be 90.6-91.5%. ⚠️The 109.81㎡ floor area includes a 9.31㎡ built-in garage (8.5% of the total), and this article values the building on the full floor area. Excluding the garage, the assessed ratio would be 87.3%. As a new build, the building is counted with the full 22-year statutory useful life for wooden structures remaining.

The photo check used on-site photos of the same property listed on SUUMO. At the time they were taken, the building was still under construction with scaffolding and sheeting, so the finished exterior has not been confirmed. The front road and the plot (the concrete apron in front of the garage) are at the same level, with no step, stairs or retaining wall visible. Distances for nearby places: the three shops use the distances stated on SUUMO, and the three restaurants are straight-line distances from the estimated property position (the development's address geocoded with the GSI service) to their OpenStreetMap locations. All six are confirmed to be in Nagareyama.
