solid

⚠ At this price the property almost certainly needs major renovation before it can rent — the yield above already folds in an estimated renovation budget. The raw price-only yield would look far higher but isn't achievable until that work is done.

Basis: 78.66m² × ¥1000/m²/mo × 0.7 age factor (Gunma) + ¥6M est. renovation. Gross yield = annual rent ÷ (price + est. renovation), before tax, vacancy, and management. Regional rent rates are conservative order-of-magnitude medians (public rent surveys), not a guarantee — rural demand can be thin. Always validate locally before relying on any figure.
