Rent-driven metrics
Based on OpenRent comparables.
- Rent ratio — Monthly rent ÷ purchase price (1% rule). 1%+ = strong, 0.8–1% = okay, <0.8% = weak for cashflow.
- Max investor price — Rent ÷ 0.8%; the price at which rent would be 0.8% of price (Stoke-style target).
- Target investor price — Rent ÷ 1%; the price at which rent would be 1% of price (strong cashflow band).
- Gross yield — Annual rent as % of purchase price (no costs).
- Cost-to-rent — Price ÷ annual rent (from OpenRent comparables). Under 14× = strong, 14–16× = acceptable, 17×+ = compressed.
- Cashflow — Rent minus mortgage, 10% maintenance, £25/mo compliance. Assumes 75% LTV, 3.95% APR (5yr fixed), 25yr term.
- ROI — Annual profit ÷ cash in (deposit + 4% purchase costs).
