Mortgage rates stay near record lows

30-year fixed-rate mortgage rate averages 2.91% for the week ending Aug. 27, falling 8 basis points from 2.99% in the prior week and down from 3.58% a year ago, according to the Freddie Mac Primary Mortgage Market Survey.

Calling this year "anything but normal," Freddie Chief Economist Sam Khater says near record-low mortgage rates "continue to incentivize potential buyers and the home buying season, which shifted from spring to summer, will likely continue into the fall."

15-year FRM averages 2.46% vs. 2.54% in the prior week and 3.06% at this time last year.

5-year Treasury-indexed hybrid adjustable rate mortgage averages 2.91%, unchanged from the previous week, and down from 3.31% a year ago
