The good news just keeps on coming for homebuyers. The only increase in average mortgage rates today was for 30-year fixed jumbo loans, which inched up a mere 0.02%.

After the Federal Reserve recently raised its benchmark federal funds rate, and many banks subsequently bumped their prime rates -- that is, the rates they charge their most creditworthy customers -- experts expected mortgages would begin creeping up. Thankfully for folks shopping for homes, those increases have yet to materialize, and rates remain near historically low levels.

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