Average interest rates on 15-year fixed-rate loans dropped from 3.4 percent to 3.33 percent with 0.7 point. A year ago, these loans averaged 2.77 percent.
Rates on five-year adjustable loans averaged 3.08 percent, down from 3.12 percent in the previous week and up from 2.63 percent in the same week a year ago.
For one-year, adjustable rate loans, rates averaged 2.51 percent, down from 2.55 percent. One year prior rates for adjustable one-year loans averaged 2.53 percent.
