According to the Mortgage Bankers Association’s Weekly Applications Survey, refinance activity fell last week as average mortgage rates increased. The Market Composite Index, which measures both refinance and purchase activity, fell 7.4 percent from the week before, largely due to a 9.0 percent drop in the Refinance Index. Purchase application volume, on the other hand, was up slightly, rising 0.9 percent. The average contract interest rate for 30-year fixed-rate mortgages with conforming loan balances moved up to 3.86 percent from 3.76 percent a week earlier. Still, mortgage rates remain near historic lows. Also in this week’s survey, the investor share of home purchase applications rose to 5.7 percent in the month of July and the share of purchase mortgages for second homes increased to 5.8 percent from 5.6 percent in June.
