How We Checked This Property
We worked from the nine listing photographs and the floor plan, together with the 2026 roadside land value map. Because we suspected this might be a terraced house, we have also recorded how that question was settled.
What We Could Not Confirm
- The property is currently tenanted and sold with the tenancy in place; handover is by negotiation. The terms of the tenancy and the history of the rent cannot be read from the listing.
- All nine listing images are only 360 by 640 pixels, with no higher-resolution versions available. We could not judge the condition of the exterior walls or foundations from the photographs.
- Given the building's age, the scope and cost of repairs required after purchase need to be established on site, bearing in mind that the seller does not accept liability for non-conformity.
※ Rather than reproducing the listing as-is, we verified the figures against public sources such as the official road price maps and the listing photos. This is not based on a site visit, so please confirm on site and with the seller before deciding.

About This Property
This is a tenanted detached house with a 52-year-old timber building. Because that is well beyond the 22-year statutory service life for timber construction, our assessed valuation treats the building as worth nothing. The seller does not accept liability for non-conformity, and the listing itself states that the building is deteriorated. This property should be viewed on the assumption that repairs will be required after purchase.
Obukuro Station on the Tobu Isesaki Line is a 10-minute walk away. Kita-Senju is about 30 minutes and Tokyo Station about 45 minutes including a transfer. A supermarket is one to two minutes on foot, and a drugstore, primary school and post office are all within walking distance.
The land measures 72.73 sqm on the register, with a 9.0 m frontage, and meets a 4.0 m road on the west side along 9.0 m. There is no private road burden, the ground is level, and no setback is noted. The building is a two-storey timber house of 45.51 sqm with a 3SDK layout and a sunroom on the ground floor.
We initially suspected this might be a terraced house. In the single exterior photograph, the eaves and the balcony railing appeared to run continuously into the neighbouring dwelling on the left. Enlarging the floor plan resolved it: sliding windows are drawn on both the left and right end walls of the first floor. A party wall separating dwellings cannot contain openings, so windows on both sides rule out a terrace. Aerial imagery confirmed it — this is a standalone building with a brown tiled roof, while the neighbour to the north has a silver hipped roof and the one to the south a dark roof, each a separate structure. What looked continuous in the photograph turned out, on magnification, to be this property's own balcony and a reed screen.
Our assessed valuation uses the 2026 inheritance-tax roadside land value of 105,000 yen per sqm, giving a land value of 7.63 million yen against the asking price of 7.0 million yen — an assessed ratio of 109.1%. That roadside value has risen for three consecutive years: 97,000 yen per sqm in 2024, 100,000 in 2025 and 105,000 in 2026. The gross yield is 9.94% on the listed figures, but given the age of the building, expected repair costs should be set against that.
