Tanya Toumadj, chief executive at Mortgage Broker Tools (pictured), said: “Property prices have risen at their strongest level in nearly seven years over the last 12 months, according to the Halifax House Price Index. Mortgage lenders have increased their appetite to offer customers larger loans in the same period, but not nearly at the same rate.”
Toumadj added that the spread was growing between the largest loan sizes offered to customers by different lenders.
