Today's mortgage rates - April 20, 2017. Mortgage rates barely moved this week, but did decline just enough for 30-year rates to reach new lows for 2017. According to Freddie Mac, the average conforming 30-year fixed-rate mortgage shed two basis points (0.02 percent) to slide to 4.08 percent. Fifteen-year fixed rate mortgages eased a similar amount, with that .02 decline good enough to tie a low for the year.
Mortgage rates vary depending upon the down payment of the consumer, their credit score, and the type of loan that will be acquired by the consumer. For instance, in February, 2010, the national average mortgage rate for a 30 year fixed rate loan was at 4.750 percent (5.016 APR). The 15 year fixed was at 4.125 percent (4.312 APR) and the 5/1 ARM was at 3.875 percent (3.122 APR). These prices are just a snapshot of the average and will change.
