Historically, low mortgage rates still in the low 6 percent range. At 6.4 percent, the average 30-year fixed rate mortgage rate remains near 40-year lows. This is more than an entire percentage point below 2000 levels. For example, a $250,000 loan, a drop from 7.5 percent to 6.5 percent means an annual savings of $2,000. Buying now can save you money.
