Freddie Mac released the results of its Primary Mortgage Market Survey finding mixed results for both long- and short-term rates, with the 30-year rising slightly and the 15-year falling just as slightly. The 30-year fixed-rate mortgage (FRM) averaged 4.74 percent with an average 0.8 point for the week ending January 20, 2011, up from last week when it averaged 4.71 percent. Last year at this time, the 30-year FRM averaged 4.99 percent. Meanwhile the 15-year FRM this week averaged 4.05 percent with an average 0.8 point, down from last week when it averaged 4.08 percent. A year ago at this time, the 15-year FRM averaged 4.40 percent. “Mortgage rates were little changed during the holiday week amid reports that inflation remains tame,” says Frank Nothaft, vice president and chief economist, Freddie Mac.
