Mortgage rates around the country edged up this week, but economists said the rates remain low enough to keep the housing market healthy.

The average interest rate on 30-year fixed-rate mortgages was 6.13 percent, compared with 6.03 percent last week, Freddie Mac said Wednesday in its weekly nationwide survey. For the week ending Nov. 15, 30-year rates were at 5.94 percent, the lowest level since Freddie began tracking the benchmark rate in 1971. It also had marked the seventh time this year that 30-year rates hit a new low.

"Mortgage rates have been so low and accommodating that total home sales surged in October as families took advantage of the affordable atmosphere," said Frank Nothaft, Freddie's chief economist.

Rates for 15-year fixed-rate mortgages, a popular option for refinancing, rose to 5.57 percent, compared with 5.44 percent last week.

Total mortgage loan applications dipped by 5.8 percent last week from the previous week but remained at brisk levels, the Mortgage Bankers Association of America said Wednesday. Refinancing activity accounted for 76.6 percent of those applications.

For one-year adjustable-rate mortgages, rates increased to 4.19 percent this week, compared with 4.14 percent last week.

This week's mortgage rates do not include add-on fees known as points. The 30-year mortgage loans carried an average fee of 0.6 point this week, while 15-year mortgages and 1-year ARMs each carried an average fee of 0.5 point this week.
