[Assessed 90.7%] Detached house in Chuo Ward, Sagamihara, Kanagawa — 10 min from Kamimizo Sta.

We traced the neighbourhood roads of Kamimizo 7-chome on the 2026 road-price map (sheet 78162). The index for Chuo Ward lists 'Kamimizo' as one entry without chome, so we located the sheet from the Geospatial Information Authority address search and the '上溝７丁目' label, Kamimizo Elementary School and block numbers on the map. Roads inside 7-chome range from 95,000 to 115,000 yen per sqm; 110,000 yen was the most frequent and is used as the representative value. The band along the prefectural road to Chigasaki (marked) and the through road to Tanaka Bridge were excluded. Three-year trend: 100,000 (2024), 105,000 (2025), 110,000 (2026) on the same roads of the same sheet.

'Oaza Kamimizo' in Chuo Ward (the part without chome numbering) carries leasehold symbol E (50 percent) and is outside our coverage. This house is in Kamimizo 7-chome, where every road on the map carries symbol D; we confirmed both the listed address and the chome label on the sheet. Frontage is on one side (north-east); the width is 4.0 m on Kenbiya and 3.9 m on SUUMO. Taken conservatively at 3.9 m it may be an Article 42-2 road, so whether a setback is needed on rebuilding should be confirmed. Nothing states the lot cannot be rebuilt.

Kenbiya carried only two floor-plan images and no site photo. We confirmed the same property (Kamimizo 7-chome, 29.99 million yen, 124.36 sqm land, 103.91 sqm building, built September 2017) on SUUMO and judged from its exterior photo. The north-east frontage road is a flat asphalt neighbourhood road, the lot is level with it and a car is parked in the carport without a step. The entrance step is one or two risers (under 0.3 m); there is no retaining wall, no level difference and no stair access. The whole frontage touches the road — not a flag lot and not a terraced unit. The neighbour's block wall across the road (4–5 courses) is a boundary wall with the same ground level on both sides, not a retaining wall. The rear (south-west) boundary is not in the photo and remains unchecked.

Wooden two-storey 4LDK, built September 2017 (9 years). With 13 of the 22 statutory years remaining, the building is assessed at about 13.51 million yen — close to half of the total and roughly equal to the land (about 13.68 million yen), a different structure from older houses assessed on land alone. The remaining years decrease by one each year, so the ratio will decline over time. Currently vacant; the listing says room cleaning will be completed in October 2026. Listed as a rental house on Kenbiya but with no expected rent or yield.

The listed 124.36 sqm (registered) is used as-is. Kenbiya's land area excludes private roads by definition, and SUUMO also shows 'no private-road burden' and 124.36 sqm. No flag lot, slope or setback is mentioned, so no deduction was applied.
