More good news on the mortgage rate landscape today: There were little, if any, changes in rates except for adjustable-rate mortgages (ARMs). Somewhat surprisingly, ARM mortgage were even less expensive again today.

After the recent increase in the Federal Reserve's benchmark rate and subsequent move by many banks to bump their prime rate -- what they charge their most creditworthy customers -- pundits expected an increase in the ARMs rate. But so far, so good.

Bottom line: It's still a great time to be shopping for a home.
