After reaching new record lows last week, fixed mortgage rates remained virtually unchanged this week, Freddie Mac reported Nov. 29 in its weekly Primary Mortgage Market Survey.

The 30-year fixed-rate rose 0.01 percentage points to 3.32 percent (down from 4.00 percent a year ago). The 15-year fixed-rate also increased by 0.01 percent points to 2.64 percent (down from 3.30 percent a year ago).

The one-year adjustable-rate mortgage remained steady at 2.56 percent (down from 2.78 percent a year ago). The five-year Treasury-indexed adjustable-rate decreased 0.02 percentage points, to 2.72 percent (down from 2.90 percent a year ago).

“Mortgage rates were virtually unchanged this week amid growing concerns around the fiscal cliff,” Frank Nothaft, Freddie Mac vice president and chief economist, said in a news release. “Although low mortgage rates failed to boost new home sales in October, year-to-date sales are up 20 percent compared with 2011 volumes, and there are growing signs of a turnaround in house prices.” Nothaft added that the S&P/Case-Shiller national home price index rose 5.2 percent over the first three quarters of this year, and that all 20 city indices had positive growth over the first 9 months.
