Buy-to-Let Affordability Calculators
Buy-to-Let Affordability
Estimate your BTL borrowing potential
Lenders test affordability against a higher notional rate, not your actual pay rate, to ensure the loan remains affordable if rates rise.
Most lenders require rental income to cover 125-145% of the mortgage payment, depending on your tax status.

Buy-to-let borrowing is typically capped at 75% loan-to-value (a 25% deposit), so we also check your deposit against this limit. Your actual maximum will be whichever figure is lower.
