How We Checked This Property
We reviewed 2 listing photos and the fiscal-2026 roadside land price map (sheet 26043) to work out how to treat a building whose structure is listed as "other," and what we could confirm about the rear boundary.
What We Could Not Confirm
- The road-frontage and private-road-burden fields are blank, so the road widths and types cannot be confirmed from the listing.
- The boundary between the neighboring lot and the rear of the main building and annex does not appear in any listing photo and remains unconfirmed.
- The basement floor cannot be assessed from the exterior, so its use and condition are unknown from the listing.
※ 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 detached rental house is in Kasumigaseki-higashi 2-chome, Kawagoe City, Saitama, a 6-minute walk from Kasumigaseki Station on the Tobu Tojo Line. The asking price is 13.5 million yen. The property is sold under a sale-and-leaseback arrangement: the current owner still lives there and plans to lease it out after handover at an estimated rent of 80,000 yen per month (a 7.11% gross yield). The seller holds a buyback option exercisable from year 10 onward, capped at 12 million yen if exercised.
The main building was built in June 1996, with a total floor area of 174.93 sq m across 3 floors above ground and 1 basement floor. The first floor houses a shop, and the basement cannot be assessed from the exterior photos. An annex building (2-story wood-frame with a flat roof, built September 2011, 21.16 sq m on the first floor and 22.07 sq m on the second) is also included in the sale. The lot sits on a corner and appears in photos to face two public roads, but the listing leaves the road-frontage and private-road-burden fields blank, so the road widths and types are unconfirmed. The boundary with the neighboring lot behind the main building and annex does not appear in any listing photo and remains unconfirmed as well.
The listing describes the main building's structure only as "other," with tiled exterior walls but no stated frame material. Because we could not confirm the frame material, this article treats the main building's assessed value as 0 yen (a conservative approach) and enters "wood" in the structure field purely for evaluation purposes. Under this treatment, the land-only assessed ratio is 118.4% (an assessed land value of roughly 15.99 million yen against the 13.5 million yen price). Adding the annex building (wood-frame, 15 years old, 7 years of remaining depreciation life, assessed at about 3.03 million yen) brings the ratio to 140.8%. If the main building actually turned out to be reinforced concrete, its assessed value could add roughly 20.88 million yen; if heavy-gauge steel, roughly 6.17 million yen -- either would push the ratio higher still. We used 120,000 yen/sq m, the most common roadside land price on the block in Kasumigaseki-higashi 2-chome, as the reference value (excluding the boundary road, the most common value is 125,000 yen/sq m, which would give a land-only ratio of 123.3%).
Several open questions remain: the leaseback and buyback terms, the unconfirmed road frontage and private-road burden, the basement floor's condition, and the unconfirmed rear boundary. With those caveats in mind, this is a property where even the land-only assessed value already exceeds the asking price.
