There was very little change in mortgage rates today, though most loans inched up a meager 1 basis point -- a basis point equals 1/100 of a percent -- except for the 5/1 adjustable-rate mortgage (ARM), which creeped up all of 2 basis points.

The 5/1 ARM offers borrowers a fixed rate for five years, then it will adjust based on the prevailing rates following the fixed period.

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