Mortgage rates drop to lowest level this year

Mortgage rates fell this week to the lowest level of the year, as rates fell on U.S. government securities. Fixed mortgage rates closely track interest rates paid on long-term Treasury bonds.

The average rate on a 30-year fixed rate mortgage dipped to 4.93 percent this week from 5 percent a week earlier, Freddie Mac said Thursday. It was the lowest level since mid-December, when rates averaged 4.81 percent.

The drop came as investors shifted money from risky European debt to safer U.S. securities. Bond yields fell as a result, and that lowered mortgage rates.
