Mortgage rates inched lower Tuesday. Mortgage-backed securities have now recovered about half of the losses experienced since the last Fed meeting on March 13th. This morning, the S&P/Case-Shiller 20-city home price index reported a decline of 3.9% from one year ago. Consumer Confidence fell to 70.2, a bit less than expected. Results from today’s 2-year Treasury auction will be released at 1:00 PM.
