How We Checked This Property

A new house before completion. As the building carries its full assessed value, we verified the land route price's location and the building calculation separately.

Locating the road price

The At Home listing of the same property revealed the street number, letting us fix the position to the lot. The front road's price is not printed on the property's map sheet, so we traced the same road onto the neighbouring sheet and read 100,000 yen. Using the 105,000 yen southern route instead still gives 88 percent, so the conclusion holds.

Building valuation assumptions

As a new build completing in August 2026, we valued the building at the full amount: a replacement cost of 220,000 yen per sqm times 103.50 sqm, or 22.77 million yen. The building accounts for six-tenths of the combined assessment.

On-site check from photos

The Kenbiya listing carries only a floor plan and plot plan, so we took the frontage-road and exterior photographs from the same property's At Home listing. The road meets the plot with no step, height differences to neighbours are under 1 metre, and there are no retaining walls or stepped access.

Effective land area

The land area is stated two ways — 152.39 sqm surveyed and 152.13 sqm registered — and we used the smaller registered figure. A regular plot fronting a 4-metre public road on the north, with no private-road burden.

What We Could Not Confirm

  • The house is not yet finished; completion is scheduled for August 2026 and handover is by negotiation.
  • It is listed as a rental detached house, but the projected rent and yield are not stated and require enquiry. An income estimate is not yet possible.
  • Kotesashi Station is an 18-minute walk. If let out, the distance to the station weighs on competitiveness.

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

A newly built detached house in Kotesashi-minami 2-chome, Tokorozawa City, Saitama, an 18-minute walk from Kotesashi Station on the Seibu Ikebukuro Line. Completion is scheduled for August 2026 and the house is not yet finished. A convenience store sits about 195 metres from the property and a supermarket about 828 metres.

The land measures 152.39 sqm surveyed / 152.13 sqm registered, and the building 103.50 sqm — a wooden two-storey 4LDK with side-by-side parking for two cars. The regular-shaped plot fronts a 4-metre-wide public road on the north with no private-road burden. Tenure is freehold; zoning is Category 1 Low-Rise Exclusive Residential with a 50 percent building coverage ratio and an 80 percent floor area ratio. It is listed as a rental detached house, with the projected rent by enquiry.

We used the smaller registered figure of 152.13 sqm. Applying the fiscal 2026 inheritance-tax road price of 100,000 yen per sqm gives a land value of 15.21 million yen, and as new wooden construction the building is valued at the full 22.77 million yen. The combined 37.98 million yen against the 43.9 million yen asking price gives an assessed ratio of 86.5 percent. The road price has risen 4.2 percent over three years, from 96,000 to 100,000 yen.

The same property's At Home listing let us confirm the street number and site photographs. The frontage road meets the plot with no step, and height differences to the neighbouring plots are under 1 metre. There are no retaining walls or stepped access.

Estimated Financing

Assessed value ¥37,983,000 → estimated loan ¥37,980,000 (87% of the asking price)
