Freddie Mac has released the results of its Primary Mortgage Market Survey (PMMS), showing fixed mortgage rates finding new record lows as the 30-year fixed-rate mortgage (FRM) averaged 3.31 percent with an average 0.7 point for the week ending Nov. 21, 2012, down from last week when it averaged 3.34 percent. Last year at this time, the 30-year FRM averaged 3.98 percent. Also this week, the 15-year FRM this week averaged 2.63 percent with an average 0.7 point, down from last week when it averaged 2.65 percent. A year ago at this time, the 15-year FRM averaged 3.30 percent. "Fixed mortgage rates continued to ease somewhat this week to record lows and should help the ongoing housing recovery," said Frank Nothaft, vice president and chief economist, Freddie Mac. "Already, new construction on homes was up 3.6 percent in October to the strongest pace since July 2008." The five-year Treasury-indexed hybrid adjustable-rate mortgage (ARM) averaged 2.74 percent this week with an average 0.6 point, the same as last week. A year ago, the five-year ARM averaged 2.91 percent. The one-year Treasury-indexed ARM averaged 2.56 percent this week with an average 0.5 point, up from last week when it averaged 2.55 percent. At this time last year, the one-year ARM averaged 2.79 percent. "In November, homebuilder confidence rose for the sixth straight month to its highest reading since June 2006 according to the NAHB/Wells Fargo Housing Market Index," said Nothaft. "And existing home sales increased 2.1 percent in October to an annualized pace of 4.79 million, exceeding the market consensus forecast."
