Mortgage rates kept slipping today, with slight drops almost across the board. The average rates for most varieties of home loans dipped by 1 or 2 basis points (a basis point equals 1/100 of a percent) -- a nice change after last week, which featured multiple small increases.

Though fixed rates inched down across the board, adjustable rate mortgages (ARMs) bucked the downward trend, rising by 1 basis point.

The slow but steady increases in rates for most of last week were seen by some as a precursor of what was to come following February's 0.25% increase in the Federal Reserve's benchmark fed funds rate. But today's declines make it two in a row, so Fed-related concerns can be put to bed -- for now.

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

For homeowners considering tapping into their home's equity, there was not much change today in home equity lines of credit (HELOC) or home equity loans. Both rates remain above last month's 5.16% and 5.28%, but at 5.30% and 5.29% are still relatively attractive.
