[Assessed 89.4%] Detached house in Chuo Ward, Sagamihara, Kanagawa — 9 min from Kamimizo Sta.

This is a newly built detached house in Yokoyama 6-chome, Chuo Ward, Sagamihara, Kanagawa. It is Building No. 3 of a three-house subdivision: a two-story wooden 4LDK house (total floor area 108.92 m²) completed in August 2026 and offered vacant for immediate handover. The nearest station is Kamimizo on the JR Sagami Line; listings give a 7 to 9-minute walk, so we use the longer 9 minutes. The site is a flag-shaped lot that reaches a 6 m public road (Building Standards Act Article 42-1-1) on the northeast through a 3.0 m wide access strip. It lies in a Category 1 medium-to-high-rise residential zone (building coverage 60%, floor area ratio 200%), a quasi-fire prevention district, and a residential land development regulation area.

The price is 41.99 million yen. The land is 130.95 m² (freehold, no private road share), of which about 34 m² is the access strip. There is no built-in garage; two cars park in tandem on the access strip. The listing states insulation grade 5 and an energy-saving rating of 3 stars. It is listed as a rental house, but no expected rent or yield is given. Buildings No. 1 and No. 2 in the same subdivision are listed at 42.99 and 46.99 million yen, and an early listing from March 2026 showed a higher price range.

The assessed value ratio is about 89.4%. Every local street in Yokoyama 6-chome carries a route price of 140,000 yen/m² (FY2026, leasehold ratio D), up 12.0% over two years from 125,000 (FY2024) and 130,000 (FY2025). The land is valued at 96.95 m² after deducting the roughly 34 m² access strip; without the deduction the ratio would be about 100.7%. Because the house is new, the building accounts for about 64% of the assessed value. The building value falls by about 1.09 million yen each year, so the ratio is calculated to drop to about 86.8% in August 2027 when the house turns one year old.

⚠️ The rear (southwest) boundary does not appear in any listing photo, so level differences there could not be confirmed from photos. GSI elevation data shows the ground outside the site sloping down toward Yokoyama Koen-dori, with a difference of about 0.3–0.4 m within a few meters of the boundary, but an on-site check is needed. Measured in a straight line from the subdivision's listed coordinates, Gyomu Super is about 150 m, Lawson about 190 m, Welcia about 500 m, Asaichi Shokudo about 190 m, Hamazushi about 270 m, and Tenya about 510 m away (OpenStreetMap). The listing says Yokoyama Park is about a 2-minute walk.
