There were few changes in mortgage rates to kick off the week. What little changes there were included a swing of a mere 1 basis point (a basis point equals 1/100 of a percent) in the 30-year fixed rate, which edged down a notch, along with a slight bump in the 15-year fixed refinance loan, which inched up 2 points.

Most of today's rates continue to compare favorably with last month's, other than adjustable-rate mortgages (ARMs), which are slightly higher but are still awfully attractive.

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