More good news to share today: Mortgage rates are on the decline again, though they're only modestly lower than they were yesterday. One of the biggest declines was in the average 30-year fixed-rate mortgage rate, which dropped from 3.87% to 3.83%. Adjustable-rate mortgage (ARMs) rates also headed south today.

The 5/1 ARM, which jumped 0.04% yesterday to 3.16%, gave up that gain and is back to where it started the week. The 5/1 ARM offers a fixed rate for five years, then adjusts based on the prevailing rates.

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