The average rate on a 30-year mortgage in Nevada rose to 6.12 percent, marking the first increase in seven weeks, according to data released by mortgage buyer Freddie Mac.

The rate rose from 6.08 percent the previous week but remains significantly lower than the 7.49 percent average from a year ago. The increase follows a period in which rates had reached their lowest level in two years, providing a temporary boost to home buyers’ purchasing power as they navigated a housing market where prices are still near record highs.

In addition to the rise in 30-year mortgage rates, borrowing costs for 15-year fixed-rate mortgages, popular with homeowners seeking to refinance, also saw an uptick. The average rate increased to 5.25 percent from 5.16 percent two weeks ago. A year ago, the 15-year rate averaged 6.78 percent, offering some relief to homeowners hoping to lower their payments, though the recent rise may curb that advantage.

Mortgage rates are influenced by movements in the bond market, particularly the Federal Reserve decision on interest rates, which can impact the 10-year Treasury yield. Lenders use the yield as a guide to setting home loan prices, and this week, the ten-year Treasury yield rose to 3.82 percent, up from 3.78 percent last week.
