30-year fixed rate falls to 3.91%

Average long-term U.S. mortgage rates fell for a third straight week amid anxiety over developments in the U.S. economy that lifted bond prices.

Mortgage giant Freddie Mac said the average rate on a 30-year fixed-rate mortgage dropped to 3.91% this week from 3.98% a week earlier. The rate on 15-year fixed-rate mortgages declined to 3.13% from 3.17%.

The average fee for a 30year mortgage was unchanged at 0.6 point. The fee for a 15-year loan also held steady at 0.6 point.
