Reasonable price on a 30-year loan within the U.S. ticks as much as 6.12%, first build up in 7 weeks

The average rate on a 30-year mortgage in the U.S. rose to 6.12% this week, the first increase in seven weeks.

The rate ticked up from 6.08% last week, mortgage buyer Freddie Mac said Thursday. A year ago, the rate averaged 7.49%.

Last week, the average rate slipped to its lowest level in two years, boosting home shoppers’ purchasing power as they navigate a housing market with prices near all-time highs.

Borrowing costs on 15-year fixed-rate mortgages, popular with homeowners seeking to refinance their home loan to a lower rate, increased again this week. The average rate rose to 5.25% from 5.16% last week. A year ago, it averaged 6.78%, Freddie Mac said.

Mortgage rates are influenced by several factors, including how the bond market reacts to the Federal Reserve’s interest rate policy decisions. That can move the trajectory of the 10-year Treasury yield, which lenders use as a guide to pricing home loans. The yield on the 10-year Treasury was at 3.82% Thursday, up from 3.78% last week.
