Mortgage rates around the country fell sharply this week, providing house hunters with an incentive to become home owners.

The average interest rate on 30-year fixed-rate mortgages was 6.13 percent this week, down from 6.31 percent last week, Freddie Mac said Thursday in its weekly nationwide survey of mortgage rates.

This week's rate was the lowest since the week ending Oct. 11, when rates on the 30-year mortgage dropped to 5.98 percent, the lowest level since Freddie Mac began tracking the rates in 1971. That marked the sixth time this year that 30-year rates reached a new low.

"With mortgage rates falling this week from already affordable levels, interest in home buying will remain strong coming into and through the holiday season," said Frank Nothaft, Freddie Mac's chief economist.

Low mortgage rates this year have been feeding a refinancing boom. Extra cash or savings from refinancing deals is helping to support consumer spending, including home buying, even as consumer confidence erodes and the job market remains sluggish. Home sales are expected to post records this year.

Rates for 15-year fixed-rate mortgages, often used for refinancing home loans, also dropped this week, to 5.51 percent, compared with 5.70 percent last week.

For one-year adjustable-rate mortgages, rates dipped to 4.25 percent, compared with 4.30 percent last week.

This week's mortgage rates do not include add-on fees known as points. Each loan type carried an average 0.6 point fee this week.

A year ago, 30-year mortgages averaged 6.56 percent, 15-year mortgages were at 6.04 percent and one-year ARMs stood at 5.26 percent.
