After yesterday's relatively substantial jump in average mortgage rates across the U.S., including a 0.09% hike in 30-year fixed refinance loans, today's across-the-board declines were a welcome surprise. For existing homeowners pondering an equity loan, there's little change on that front.

Not only did mortgage rates drop today, virtually all loan types eased more than yesterday's spike led by a 0.11% decline in 30-year fixed rates. It appears Tuesday's uptick was more of a hiccup than a precursor of what's to come.

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