“This year has been anything but normal and as the uncertainty lingers, mortgage rates remain near record lows,” said Sam Khater, Freddie Mac’s Chief Economist. “These rates continue to incentivize potential buyers and the home buying season, which shifted from spring to summer, will likely continue into the fall.”
Main takeaways from this week's report:
30-year fixed-rate mortgage  averaged 2.91% with an average 0.8 point for the week ending August 27, down from last week when it averaged 2.99%. A year ago at this time, the 30-year FRM averaged 3.58%.
15-year fixed-rate mortgage averaged 2.46% with an average 0.7 point, down from last week when it averaged 2.54%. A year ago at this time, the 15-year FRM averaged 3.06%.
5-year Treasury-indexed hybrid adjustable-rate mortgage  (ARM) averaged 2.91% with an average 0.2 point, unchanged from last week. A year ago at this time, the 5-year ARM averaged 3.31%.
The PMMS is focused on conventional, conforming, fully-amortizing home purchase loans for borrowers who put 20% down and have excellent credit. Average commitment rates should be reported along with average fees and points to reflect the total upfront cost of obtaining the mortgage.

In a separate survey of rates by Bankrate  this week, the average 30-year fixed-rate mortgage maintained last week's record low of 3.14%. (According to MSN Money , the gap with Freddie Mac's number is because Bankrate's figure includes points and origination fees averaging 0.33%, while Freddie's number excludes those costs. Freddie Mac said its average is accompanied by an average of 0.8 of a point.)
