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 £1,661 supports a loan of about £249,931, which is 58.1% of the average price. That falls short of 75% loan-to-value, so a buyer of an average home here needs a larger deposit or a stronger rent to pass the stress test. Both numbers are conventions rather than rules — change them in the stress test.
