Average mortgage rates unchanged at 4.37 pct.

NEW YORK (AP) — Rates on 30-year mortgages this week were unchanged from the previous week, staying slightly above the lowest level in decades.

Mortgage buyer Freddie Mac says the average rate for 30-year fixed loans this week was 4.37 percent. Earlier this month, the rate dipped to 4.32 percent, which was the lowest level on records dating back to 1971.

The average rate on 15-year fixed loans also was unchanged at 3.82 percent. That is the lowest on records dating back to 1991.

Rates have fallen since spring as investors poured money into the safety of Treasury bonds, lowering their yield. Mortgage rates tend to track those yields.
