How We Checked This Property
We counted the block roads in Namiki 9-chome one by one on the 2026 road price map to set the representative value, checked the lot shape and road access on the plot plan, and checked level differences with 16 listing photos and GSI elevation data.
What We Could Not Confirm
- The rear (northwest) and opposite neighbouring boundaries could not be checked in the photos; the boundary details and any level difference need on-site confirmation.
- The house is scheduled for completion in November 2026 and is currently unfinished, so the finished exterior and landscaping have not been confirmed.
- It is listed as a detached rental house, but the yield and expected rent are undecided, and the achievable rent if let has not been confirmed.
- The lot is within a designated residential land development regulation area, so works involving cut or fill above a certain scale require permission.
- The exact position of lot number 1563 has not been fixed on the road price map; the front road is taken to be either the 74,000 or the 76,000 yen/m² band.
※ 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 an unfinished new house scheduled for completion in November 2026 (handover planned for early December 2026). The building is assessed on the planned floor area shown in the listing. It is located in Namiki 9-chome, Abiko, Chiba, and is the single new house (Building A) sold as "Heartful Town Namiki 9-chome". It is a 19-minute walk (about 1,520 m) from Abiko Station on the JR Joban Line and 23 minutes from Tennodai Station. The area is a Category 1 low-rise exclusive residential zone (building coverage 60%, floor area ratio 150%) with a 10 m height limit, shadow regulations and landscape rules, and it lies within a designated residential land development regulation area. According to the listing, Namiki Elementary School is about 770 m away and Abiko Toho Hospital about 850 m.
The building is a two-storey wooden 4LDK (LDK about 17 tatami) with a floor area of 103.5 m², on 173.91 m² of freehold land (surveyed, land category: residential). The plot plan shows a rectangular lot facing the road, not a flag-shaped lot, fronting a 4 m public road on the southeast side with no setback. No private road share is listed. It is a ready-built house, not land with a building condition, with parking for two cars (no built-in garage), city gas, public water and sewerage. The self-assessed energy label shows insulation grade 5 and ZEH level. Kenbiya lists it under detached rental houses, but as it is still under construction there is no tenant, and the yield and expected rent are undecided. The transaction type is brokerage.
The 2026 inheritance tax road price is 74,000 yen/m², up about 19.4% over two years from 62,000 yen/m² in 2024 and 69,000 yen/m² in 2025. We use the most common value among the block roads in Namiki 9-chome as the representative value. The road in front of the property appears to be the 74,000 or 76,000 yen/m² band; using 76,000 yen/m² gives an assessment ratio of about 88.0%, and even the lowest band in the chome, 73,000 yen/m², gives about 86.7%. The land is assessed at the full 173.91 m² with no deductions, and the site's assessment ratio against the 40.9 million yen price is about 87%. Because the house is new, the building value exceeds the land value, and as the building value falls each year with age, the ratio will decline over time.
The same listing as on Kenbiya also appears on LIFULL HOME'S Investment, and we checked its 10 photos plus 6 photos of the same property on LIFULL HOME'S new detached houses. All exterior photos show the house under construction with scaffolding. The southeast front road and the lot are almost level, with only a curb of about 10-15 cm at the boundary, and there are no retaining walls, steps or stairs. The gravel parking area at the side is also level with the building. ⚠️ The rear (northwest) and opposite neighbouring boundaries do not appear in the photos; as a supplement we confirmed with GSI 1 m elevation data that the surroundings are flat low ground at 4.9-6.4 m. Distances to the nearby places below are straight-line distances from the LIFULL HOME'S map coordinates (OpenStreetMap) or the distances in the listing.
