LOS ANGELES—The average long-term U.S. mortgage rate rose to its highest level in five weeks, a setback for prospective homebuyers during what’s traditionally the busiest time of the year for home sales.
The average rate on a 30-year mortgage rose to 6.88 percent from 6.82 percent last week, mortgage buyer Freddie Mac said Thursday. A year ago, the rate averaged 6.27 percent.
