How we calculate LLP Mortgage Affordability
Methodology and data sources, updated October 2026
Formulas
- Loan the rent supports
(Monthly rent × 12) ÷ (Rental cover % ÷ 100) ÷ (Stress rate % ÷ 100)The largest loan whose interest, at the stress rate, the rent covers by the rental cover you enter.
- Loan by value
Property value × (Maximum loan to value % ÷ 100)The most a lender will lend against the property's value.
- Maximum loan
Lower of the loan the rent supports and the loan by valueWhichever limit is lower sets the loan. The deposit is the property value minus this loan.
- Rental cover at this loan
(Monthly rent × 12) ÷ (Maximum loan × Stress rate % ÷ 100) × 100How many times the stressed interest the rent covers, as a percentage.
- Monthly interest
Maximum loan × (Interest rate % ÷ 100) ÷ 12Interest-only payment at the interest rate you enter.
