Mortgage rates continued this week's trend of inching up, led by a fairly substantial 0.05% jump in 30-year fixed jumbo rates. Most other loan varieties rose, on average, by a more modest 0.02% or 0.03%.

About the only good interest rate news for borrowers came from home equity lines of credit (HELOC) and home equity loans, which held steady at 5.30% and 5.28%, respectively.

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

For a little perspective, here are where rates sat as of last Friday. Not surprisingly, adjustable-rate mortgages (ARMs) have shown little movement. Since lenders are able to adjust those loans based on the prevailing rates after the initial five-year "fixed" period ends, they assume less interest-rate risk. A similar line of reasoning applies to the shorter-term 15-year fixed rate loan.
