It's a great time to lock in your home financing.  Average rates on U.S. fixed mortgages fell for the second straight week, a welcome sign for homebuyers as rates had spiked earlier this month.

Mortgage buyer Freddie Mac said Thursday that the average on the 30-year loan fell to 4.31 percent. That's down from 4.37 percent last week but nearly a full percentage point higher than in early May. The rate reached a two-year high of 4.51 percent two weeks ago.

The average on the 15-year fixed loan declined to 3.39 percent, down from 3.41 percent last week.
