[Assessed 99.6%] Detached house in Koshigaya, Saitama — 15 min from Kita-Koshigaya Sta.

The property summary says nothing about an access strip, but the site plan attached to the floor plan shows a passage roughly 2.9 m wide and 12.6 m deep. As it cannot be built on, we deducted about 36.7 sqm and calculated on 115.5 sqm. Without the deduction the ratio would be 131.3%; with it, 99.6%.

The address is published down to the lot number, so we obtained the block coordinates for lot 34 from the Geospatial Information Authority and identified the frontage road on 2026 map sheet 39037 at 97,000 yen/sqm. The adjoining sheet 39042 carries the same block and the same figure at its edge, confirming the reading across two sheets. The district band runs 93,000 to 105,000 yen, and none of those values drops the ratio below 80%.

Built in May 2018, the house is 8 years old and has 14 of the 22 statutory years for wood-frame construction remaining, so the building is assessed at 13.49 million yen. That is 55% of the 24.69 million yen total — an unusual split among the properties on this site. The land alone would come to only 45.2%; the remaining building life is doing the work.

We opened the exterior and entrance photographs to check for steps. Gravel runs level from the access strip through to the front garden, with no step down from the road. We measured the entrance riser at 0.35 to 0.65 m using two references — the door height and the height of the full-height window — and the fence footing at the boundary at 0.1 to 0.2 m. Neither functions as earth retention.

The listing text states that there are matters requiring disclosure. The nature of those matters is not given in the listing, so we have not been able to confirm it. Given that the price is restrained for an 8-year-old house with a refurbished interior, please ask the agency what is being disclosed if you are considering a purchase.
