Lender maths on the averages. At a 5.5% stress rate and 145% rent cover — the common buy-to-let convention — the average rent of £1,367 supports a loan of about £205,693, which is 81.9% of the average price. That clears a 75% loan-to-value purchase on the rent alone. Both numbers are conventions rather than rules — change them in the stress test.
