Adjust land and building assumptions
FY2025, 393 land-attached custom homes; derived from an average construction cost of JPY 37.33M and average floor area of 104.8 m².
Areas are shown in m² (1 tsubo ≈ 3.305785 m²). The initial land and floor areas each remain 30 tsubo (about 99.2 m²). Slider steps retain the original model; displayed areas and unit prices are rounded, while estimates use unrounded values.
6 published transactions from Neighborhood, approximately 69.4 m²–128.9 m². Zoning: residential-use records preferred. Confidence: Medium.
Overall neighborhood reference: JPY 142,175 / m². It remains visible for comparison and is not automatically treated as the selected-lot estimate.
The simple floor-area-ratio ceiling for a 99.2 m² lot is about 79.3 m². The selected model exceeds this simple ceiling; the total is a comparison scenario, not a buildable-plan estimate.
Ancillary costs are provisionally set at 10% of construction cost. Public transaction records are retained; selection only changes which records are used for this estimate.
