Average interest rates for 30-year fixed rate mortgages (FRMs) are at all-time lows in two weekly surveys.

Freddie Mac’s ($0.00 0%) weekly survey put the 30-year FRM at 4.78% with a 0.7 point, down from last week when it was 4.83% and one year ago when it was 5.97%. This week’s rate ties the record for lowest ever in the weekly survey’s history, which was previously reached twice in April this year.

Bankrate.com’s survey put the 30-year FRM at 5%, a new low for the company’s survey of large US banks and thrifts, and is down 6bps from last week, which was the previous all-time low.

Freddie put the 15-year FRM at 4.29% with an average 0.6 point, a new low for the survey. Last week’s 4.32% was the previous all-time low. Bankrate.com put the 15-year FRM at 4.47%.

The five-year Treasury-indexed hybrid adjustable-rate mortgage (ARM) averaged 4.18% with an average 0.6 point in Freddie’s survey, down from last week’s 4.25%. Bankrate.com put the five-year ARM at 4.54%, down 4bps from last week. Both rates are record lows for in the respective surveys.

The one-year Treasury-indexed ARM averaged 4.35% this week with an average 0.7 point, unchanged from last week, Freddie Mac said.

“Interest rates for 30-year fixed-rate loans are currently 0.8 percentage points below this year's peak set in mid-June, which shaves roughly $100 off the monthly payments on a $200,000 mortgage,” said Frank Nothaft, Freddie Mac vice president and chief economist.
