Not much change again on the mortgage front Tuesday: After a Monday when most rates either fell by a basis point (i.e., 1/100 of a percent) or held steady, today, most home loan interest rates on average either inched up by a single basis point or remained unchanged. The lone exception was the 5/1 adjustable rate mortgage (ARM), which dropped 2 basis points to 3.22%, erasing most of Monday's 3 basis point increase.

The 5/1 ARM offers home buyers a fixed interest rate for five years, after which it adjusts annually based on the prevailing rates. The benchmark used to determine an ARM's interest rate after the fixed period is generally either the prime rate or London Interbank Offer Rate (LIBOR).

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