More good news on mortgage rates today: Except for the 30-year fixed jumbo, which jumped to 4.83% from Tuesday's 4.63%, most loan alternatives continued their slow but steady downward trend. Even adjustable-rate mortgages (ARMs) remained stable, which is a bit surprising, given the recent bumps in prime rates -- what lenders charge their most creditworthy customers -- that many banks instituted following the recent hike in the federal funds rate.

For home shoppers, here are today's average mortgage rates across the U.S., along with where they stood a month ago:

Rates may not be as attractive as they were a couple of years back, but relatively speaking, mortgages are still priced at a steep discount. For some perspective, here are a few of the rates some of us more "experienced" home shoppers were faced with 15 years ago:

For current homeowners considering taking out a home equity line of credit (HELOC) or equity loan, there was a slight change today. The strong housing market has kept average HELOC and equity loan rates fairly stable at 5.14% and 5.22%, respectively. Though the average rates for a HELOC inched up a bit, both equity loan rates remain below last month's rate of 5.26% each.
