Mortgage rates remained unchanged Wednesday as mortgage-backed securities recovered from yesterday’s late selloff. In economic news, June Housing Starts rose 7% to an annual rate of 760,000 units, beating forecast, although Building Permits, a leading indicator, fell short of expectations. The Mortgage Bankers Association weekly purchase activity index declined by 0.1%, while the refinancing activity index surged 16.9%. Average reported 30-year fixed rates fell to 3.74%, not including fees, another record low. The Fed’s Beige Book, a survey of economic activity by the 12 regional Federal Reserve Banks, will be released at 2:00 PM.
