The average rate on a 30-year mortgage in the U.S. climbed this week to its highest level since mid-February, a setback for home shoppers that threatens to slow sales further this spring homebuying season.

Mortgage rates are up today, but still under 7%. Today’s national average on a 30-year fixed-rate mortgage is 6.94%, according to Bankrate. If you choose a 15-year fixed-rate mortgage, the average rate is 6.

Average mortgage refinance rates have been volleying between 6.5% and 7% as fears of both higher inflation and an economic slowdown play tug-of-war with financial markets. Overall, rates are too high for most homeowners to save money from refinancing.
