How We Checked This Property
As the house is not yet completed and there are no on-site photos, we checked the lot shape and level differences with the plot plan and GSI elevation data, and counted the local streets of Nobidome 5-chome one section at a time on the 2026 road price maps.
What We Could Not Confirm
- As the house is not yet completed and there are no on-site photos, whether there are retaining walls and level differences to the road in front have not been confirmed. Elevation data indicate a flat site, but an on-site check or an inquiry to the agent is needed.
- Whether the lot is flag-shaped and whether the house is terraced have not been confirmed with on-site photos. The plot plan shows a regular-shaped lot that is not flag-shaped, but the relationship with neighbouring buildings (whether it is terraced) cannot be seen in photos either.
- As the building is not yet completed, the condition of its exterior cannot be confirmed (completion scheduled for March 2027, handover in late April).
- The road in front is a 4.0m-wide designated road (private road). The listing does not mention a share in this private road or consent for passage and excavation, so these need to be confirmed with the agent.
- The lot number is not disclosed, and the property's position is estimated from the listing's map position. Depending on the choice of representative road price, the assessed ratio ranges from about 79.05% to 80.95%. The expected rent and yield have not been set either.
※ 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 new detached house under construction (two-storey wooden, 4LDK) in Nobidome 5-chome, Niiza, Saitama. The nearest station is Niiza on the JR Musashino Line, a 17-minute walk away (of the 15 minutes in the listing and the 1,300m / 17 minutes in the neighbourhood section, we use the longer figure). Shiki Station on the Tobu Tojo Line is a 28-minute walk. The zoning is Category 1 Residential (building coverage ratio 60%, floor area ratio 160%). For nearby facilities, the distances for 7-Eleven and OK Store are those given in the neighbourhood section of the SUUMO listing; the others are straight-line distances from the map position shown on LIFULL HOME'S to the locations registered on OpenStreetMap.
The price is 51.99 million yen. The land is 99.03㎡ (freehold, no private-road burden) and the building has 108.03㎡ of floor area; it is not yet completed, with completion scheduled for March 2027 and handover in late April 2027. According to the plot plan, it is a regular-shaped lot with a 7.68m frontage on a 4.0m-wide road on the west side (a designated road under Article 42-1-5 of the Building Standards Act, privately owned), and it is not flag-shaped. ⚠️ The listing does not mention a share in the private road in front or consent for passage and excavation, so these need to be confirmed. Utilities are public water, public sewerage and city gas, and the plot plan shows parking for two cars. It is listed as a house for rent, but the expected rent and yield have not been set.
⚠️ As the house is not yet completed, there is not a single on-site photo of the exterior or the road in front (the thumbnail on this site is also an illustrative image, not a photo of the property). Whether there are retaining walls, level differences to the road in front, whether it is a terraced house, and the condition of the building exterior have not been confirmed with photos. GSI elevation data show a level difference of about 0.7m within a 30m radius of the listing's map position, a flat site on a plateau, but an on-site check or an inquiry to the agent is needed.
The assessed ratio is about 80.95%. The road price used is 185,000 yen/㎡ (2026, leasehold ratio D), the most common value on local streets across Nobidome 5-chome; the same section rose from 175,000 yen in 2024 to 180,000 yen in 2025 and 185,000 yen/㎡ in 2026, up about 5.7% in two years. ⚠️ However, the local streets around the map position (the northern part of the chome) are in the 175,000 yen/㎡ band, and using that value the assessed ratio would be about 79.05%. The choice of representative value changes the result by about 2 points, so the margin is small. As a new build, the building also has an assessed value, which accounts for about 46% of the price.
