An indicative long-term rental estimate — to compare listings, not an appraisal.
Basis: 76.95m² × ¥1000/m²/mo × 0.6 age factor (Oita). Gross yield = annual rent ÷ (price), 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.
Japan has real flood, landslide, and earthquake exposure that varies street by street. Check the official government hazard maps for this exact location before buying.
