Most mortgage rates decreased to start the week by about 3 to 4 basis points (a basis point equals 1/100 of a percent), with two fairly drastic exceptions. The 30-year fixed jumbo loan skyrocketed 17 basis points to 4.63%. A jumbo mortgage is a loan for a minimum of $417,000, though that amount can increase in higher-cost areas.

The other rate exception was a whopping 15-basis-point drop in the 15-year fixed refinance loan, which more than erased the 0.14% increase borrowers endured on Friday.

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