Average fixed mortgage rates in the U.S. fell in the latest week, according to mortgage-finance company Freddie Mac (FMCC), as investors watch for signals about how the spring homebuying season will play out this year.

"Mortgage rates eased a bit following the decline in 10-year Treasury yields," Freddie Mac Chief Economist Frank Nothaft noted in a statement Thursday. The U.S. economy also added fewer than expected jobs during March, though February figures were revised higher. Meanwhile, the unemployment rate held steady, Mr. Nothaft said.

Rates have wavered recently as markets watch for further signals on the Federal Reserve's bond-buying program and the U.S. economy.

For the week ended Thursday, the 30-year fixed-rate mortgage averaged 4.34%, compared with 4.41% a week earlier and 3.43% a year earlier. Rates on 15-year fixed-rate mortgages averaged 3.38%, compared with 3.47% the previous week and 2.65% a year earlier.

Five-year Treasury-indexed hybrid adjustable-rate mortgages, or ARMs, on average, were 3.09%, compared with 3.12% the previous week and 2.62% a year earlier. One-year Treasury-indexed ARM rates on average were 2.41%, compared with 2.45% the previous week and 2.62% a year earlier.
