Mortgage Rates Fell Last Week: Freddie Mac

Interest rates on fixed-rate mortgage loans fell for the third consecutive week, according to Freddie Mac.

The 30-year fixed-rate mortgage averaged 3.91% for the week ending Aug. 6. That's down from 3.98% last week, and down from 4.14% a year ago.

The 15-year fixed-rate mortgage averaged 3.13% for the week, down from 3.17% a week ago. It's down from 3.27% compared to a year earlier.

The five-year Treasury-indexed hybrid adjustable-rate mortgage averaged 2.95% this week, unchanged from a week ago.

"Uncertainty about the economy helped drive down Treasury yields early in the week, and thus mortgage rates fell 7 basis points to 3.91%, the lowest level since June 4," Sean Becketti, Freddie Mac's chief economist, said in a news release.

The figures are derived from Freddie Mac's Primary Mortgage Market Survey.
