Average mortgage rates declined nearly across the board again today, led by drops of 8 basis point in both the 30-year fixed and 30-year fixed refinance rates. (A basis point equals 1/100 of a percent.) And once again, the 15-year fixed refinance rate changed for the better, easing by 5 basis points for the second straight day. It now sits at 3.04%.

The only exceptions to the many positive changes for would-be borrowers were the ever-so-slight 1 point increases in both the 5/1 adjustable rate mortgage (ARM) and the 5/1 ARM refinance loans.

Here are today's average mortgage rates across the U.S., along with where they stood a month ago.
