Rates on 30-year fixed-rate mortgages averaged 4.47 percent with an average point of 0.7 for the week ending Dec. 19, up from 4.42 percent last week and 3.37 percent a year ago, according to Freddie Mac’s latest Primary Mortgage Market Survey.

Rates on 15-year fixed-rate mortgages, five-year Treasury-indexed hybrid adjustable-rate mortgage (ARM) loans and one-year Treasury-indexed ARMs also all increased.

The Federal Reserve announced Wednesday that it will begin to taper a stimulus program in January that has helped keep mortgage rates low.
