How We Checked This Property

We checked the 2026 route-price map, the two listings for the same property on athome and Rakumachi, the listing photos and GSI elevation data to confirm which route price to use and how to treat the disclosure matters, excess building coverage and unregistered extensions noted in the listing.

Locating the road price

We checked Shibafuji 2-chome on the 2026 route-price map. The area spans four sheets, and local-road values range from 150,000 to 220,000 yen/㎡. The most common value, 215,000 yen/㎡ (seven segments on sheet 28095), is used, and the same road was traced back to 195,000 yen/㎡ in 2024 and 205,000 yen/㎡ in 2025. Even the lowest band in 2-chome, 150,000 yen/㎡, gives a ratio of about 119.1%. The leasehold-ratio symbol is D.

On-site check from photos

We reviewed the one exterior photo and one floor plan on athome and the nine photos of the same property on Rakumachi. The front, facing the 4.0 m private road to the north, is gravel at roughly road level, with no steps, retaining walls or stairs; the entrance has a single step of about 10 cm. The house stands apart from its left neighbour, so it is not semi-detached, and it is not on a flag-shaped lot. There are no photos of the rear or the far ends of the sides, but the GSI 5 m elevation mesh shows about 100 m square around the site at 4.6–5.5 m, i.e. flat ground.

Rights and restrictions

The features list says "land readjustment area", but on the route-price map the roads in Shibafuji 2-chome carry route prices and no readjustment project area is marked. We treated it as a completed readjustment area and used the route price as is. The "unregistered extensions" and "building coverage exceeded" notes on Rakumachi do not affect the assessment ratio, because the building is valued at zero at over 60 years old, but they can affect financing and the size of any rebuilt house.

Listing check

The same property is listed on athome and Rakumachi, with matching price, areas and year built. Rakumachi's notes say there are "disclosure matters", but neither listing states what they are. Possible reasons why the 7.5 million yen price is well below the assessed land value of about 12.80 million yen are the building being over 60 years old, the small 59.53 ㎡ lot, the disclosure matters, the excess building coverage and the unregistered extensions.

What We Could Not Confirm

  • The Rakumachi listing says there are "disclosure matters", but their content is not stated and has not been confirmed.
  • For the "land readjustment area" note, whether the lot is a provisional replotting and whether the listed land area is the post-replotting figure have not been confirmed.
  • The listing does not give the current floor area including the unregistered extensions, or by how much the building coverage is exceeded.
  • There are no photos of the rear (south) boundary or the far ends of the side boundaries, so conditions along those boundaries are unconfirmed (elevation data show the surroundings are flat).
  • Because the lot number is undisclosed, the route price used is the most common local-road value in Shibafuji 2-chome (215,000 yen/㎡). Whether the 4.0 m private road in front has its own route price is also unconfirmed.

※ 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

⚠️ The Rakumachi listing for the same property states in its notes that there are "disclosure matters" (kokuchi jiko). What these matters are is not stated in either the athome or the Rakumachi listing and has not been confirmed. The same notes also say "unregistered extensions to part of the first floor and the second floor" and "building coverage ratio exceeded": there are additions that have not been registered, and the current building exceeds the designated 60% building coverage. Buildings like this can be harder to finance, and a rebuild would have to fit within current coverage limits, so a building of the same size may not be possible.

This is a pre-owned two-storey wooden detached house in Shibafuji 2-chome, Kawaguchi, Saitama. The nearest station is Warabi on the JR Keihin-Tohoku Line, a 13-minute walk; Minami-Urawa Station on the same line is a 23-minute walk. The lot number is not disclosed. Built in November 1965 (over 60 years old), it is a 3DK with a registered building area of 28.09 ㎡ on 59.53 ㎡ of land (registered), freehold. It faces a 4.0 m private road to the north, with no private-road burden. It lies in a Category 1 Residential Zone (60% coverage, 160% floor area ratio), in a quasi-fire prevention district and within the Shibafuji district plan area. It is currently vacant, and the handover date is negotiable.

The route price used is 215,000 yen/㎡, the most common value on local roads in Shibafuji 2-chome, up about 10.3% from 195,000 yen/㎡ in 2024. The assessed land value is about 12.80 million yen. The building is over 60 years old, past the 22-year statutory life for wooden buildings, so its assessed value is zero; even if the unregistered extensions make the actual floor area larger than registered, the assessment ratio does not change. The listing's features mention a "land readjustment area", but on the route-price map the roads in Shibafuji 2-chome carry route prices and no project area is marked, so we treated the readjustment as completed and used the route price as is. The Rakumachi listing gives an assumed rent of 70,000 yen a month (840,000 yen a year) and a gross yield of 11.2%, but since the house is vacant this is an assumed figure.

The price of 7.5 million yen is well below the assessed land value of about 12.80 million yen. Possible reasons include the building being over 60 years old, the small 59.53 ㎡ lot, the disclosure matters, the excess building coverage and the unregistered extensions. The exterior photo shows a gravel front on the private-road side at roughly road level, with no steps or retaining walls; the house is detached and not on a flag-shaped lot. There are no photos of the rear or the far ends of the side boundaries, but GSI elevation data show the surrounding area is flat lowland. Nearby: Maruetsu Shibatsukahara is 770 m away according to the listing; measured in a straight line from the Shibafuji 2-chome centroid, 7-Eleven Kawaguchi Shibatsukahara 2-chome is about 550 m, Big-A Kawaguchi Shiba about 830 m, Hotto Motto about 860 m, Kura Sushi about 880 m and Kaisen Shokudo Makotoya about 890 m (OpenStreetMap). The listing also names Daily Yamazaki Warabi-kita (420 m) and Welcia Warabi Kitamachi (480 m).

Regional bankLand-value focusedStrong with detached housesGood with older buildings
本業年収700万円以上が検討対象。 相続税路線価から算出した「土地の積算」が60%以上出ていれば、基本的にフルローンとなる。 修正後バランスシートも重視しており、属性枠だけで終了する訳ではない為、可能な限り「土地」が高積算の物件を買い進めていきたい。
L&Fアセットファイナンス
Non-bank lenderLand-value focusedStrong with detached housesGood with older buildings
土地値が出る築古系が得意。 属性はほぼ問わない。 どんなに担保評価が付いたとしても8割融資が目安。 建物の価値に対してはほぼ担保評価を付けてくれない為、新築や築浅の物件は要注意。 但し、建売の売れ残りや変形地等の場合は、土地が広くて担保評価が伸びたり、賃料が高くて収益還元評価が伸びたりして、思わずハマるケースがある。 また、産休中でも行けた、貴重な存在の金融機関である。
関西みらい銀行

土地から新築OK。 築古過ぎず、好立地で積算割合が高く、キャッシュフローが回る物件であれば、検討対象となる。 産休中はNG。 築古過ぎる場合は、信用金庫・信用組合のセゾンファンデックス保証付の不動産担保ローンが適す。
