## 1% Rule

- **Rent ratio:** 0.51% (weak for cashflow)
- **Max investor price (0.8%):** £225,000
- **Target investor price (1%):** £180,000

*Monthly rent ÷ price. 1%+ = strong, 0.8–1% = okay, <0.8% = weak. Max investor price = rent ÷ 0.8% (Stoke-style target). Target investor price = rent ÷ 1% (strong cashflow band). Based on OpenRent comparables.*

## Rent-driven metrics

*Based on OpenRent comparables (median £1,800/mo).*

- **Gross yield:** 6.1%
- **Cost-to-rent:** 16.4×
- **Monthly cashflow:** £197/mo (75% LTV, 3.95% APR (5yr fixed), 25yr term)
- **Cash-on-cash ROI:** 2.3%

*Gross yield = annual rent as % of price (no costs). Cost-to-rent = price ÷ annual rent (from OpenRent comparables); under 14× = strong, 14–16× = acceptable, 17×+ = compressed. Cashflow = rent − 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).*
