Freddie Mac released findings from its Primary Mortgage Market Survey today. The survey showed record lows for mortgage rates.
A 30-year fixed-rate mortgage averaged 3.89% this week, which is a much lower rate than a year ago at this time. The rate during the second week of January last year averaged at 4.71%.
A 15-year fixed-rate mortgage averaged 3.16% this week. This rate is much lower than that of last year, when a 15-year fixed-rate mortgage averaged at 4.08%.
The 5-year adjustable-rate mortgage averaged 2.82% this week. Last year, the 5-year adjustable rate mortgage averaged 3.72 percent. 
The below graphic was posted to the Christian Science Monitor just yesterday.
It shows the highest interest year as 2008. Since then, the average interest rate has dropped by from 5-6 percent to 4-3 percent.
Vice President and Chief Economist of Freddie Mac said, “Mortgage rates eased slightly this week to all-time record lows following mixed indicators in the labor market.”
