McLean, VA – Freddie Mac (OTC: FMCC) today released the results of its Primary Mortgage Market Survey® (PMMS®). While the 30-year fixed-rate mortgage rate rose, the 15-year fixed-rate dipped slightly; shorter-term rates fell.

15-year FRM this week averaged a record low of 3.82 percent with an average 0.6 point, down slightly from last week when it averaged 3.83 percent. A year ago at this time, the 15-year FRM averaged 4.47 percent.

Frank Nothaft, vice president and chief economist of Freddie Mac, reports, "Interest rates on 30-year fixed mortgages have remained below 5 percent for the last 19 weeks giving people ample opportunity to refinance their existing mortgage debt. As a result, homeowners reduced their financial obligations relative to disposable personal income during the second quarter of 2010 to the lowest share in almost eight years, according to the Federal Reserve . Currently, four out of five mortgage applications are for refinancing existing mortgage debt, based on figures by the Mortgage Bankers Association ."
