Some lenders have begun to offer first-time buyers up to five times their annual incomes to allow them to get a foot on the property ladder.
Bernard Clarke of the CML said: “It is a reflection of the growing affordability problem of first-time buyers. But it is offset by lower borrowing costs.”
Abbey and the Co-operative Bank are both currently offering mortgages up to five times a person’s salary a big change from the days when it was standard to lend at most 3.5 times a single person’s salary or 2.5 times the combined salary of a couple.

Rising house prices and a lack of affordability has resulted in the number of first-time buyers falling in recent years.
Between 1997 and 2002, the number of first-time buyers mostly stayed well over 500,000 per year, but in the last three years this has dropped to around 365,000 a year.
