According to the Mortgage Bankers Association’s Weekly Applications Survey, the Market Composite Index, which measures total mortgage loan application volume, was up 9.2 percent last week due to a 13.0 percent surge in the Refinance Index. The seasonally adjusted Purchase Index, however, fell 2.4 percent from the previous week. Michael Fratantoni, MBA’s vice president of research and economics, said the increase in refinance activity was due to a spike in the conventional sector and not because of rising government loan demand. The average contract interest rate for 30-year fixed-rate mortgages with conforming loan balances fell to another new low, dropping to 3.96 percent from 4.01 percent the week before. More here.
