CHICAGO (MarketWatch) — Mortgage rates dropped to record lows this week, with 30-year fixed-rate mortgages falling to 3.89%, its sixth week below the 4% mark, according to Freddie Mac’s weekly survey of conforming mortgage rates.

The mortgage averaged 3.91% last week and 4.71% a year ago.

Rates on 15-year fixed-rate mortgages averaged 3.16% for the week ending Jan. 12, down from 3.23% last week and 4.08% a year ago.

Adjustable-rate mortgages also dropped, with 5-year Treasury-indexed hybrid ARMs averaging 2.82%, down from 2.86% last week and 3.72% a year ago, according to the survey. One-year Treasury-indexed ARMs averaged 2.76%, down from 2.8% last week and 3.23% a year ago.

To obtain the rates, 30-year mortgages and 5-year ARMs required payment of an average 0.7 point, 15-year fixed-rate mortgages required an average 0.8 point and 1-year ARMs required an average 0.6 point. A point is 1% of the mortgage amount, charged as prepaid interest.

“Although the economy added 1.6 million jobs in 2011, which was the most since 2006, the unemployment rate remained historically elevated. The 2009 to 2011 period had the highest three-year average unemployment rate since 1939 to 1941,” he said. The government’s official jobless rate for December was 8.5%.
