  • 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.
