According to the Mortgage Bankers Association’s Weekly Applications Survey, average mortgage rates fell across all loan categories last week, including 30-year fixed-rate mortgages with both conforming and jumbo balances, loans backed by the Federal Housing Administration, and 15-year fixed-rate loans. But despite lower rates, demand for mortgage applications actually fell from the week before. In fact, the Market Composite Index – which measures both refinance and purchase application demand – was down 3.5 percent from the week before. Lynn Fisher, MBA’s vice president of research and economics, told CNBC that the number of Americans requesting loan applications is still higher than last year, though things are slowing. “Purchase application volume continues to run ahead of last year’s pace, but after growing quite strongly in the first half of the year, the rate of improvement has decelerated this summer,” Fisher said. Still, mortgage applications to buy a house are up 6 percent from one year ago. Refinance demand, on the other hand, is 56 percent higher than last year. The MBA’s weekly survey has been conducted since 1990 and covers 75 percent of all retail residential mortgage applications. More here.
