WASHINGTON (AP) — Mortgage rates were mixed last week. The key 30-year home loan remained below 3% for the fifth straight week amid continued concern over the surging delta coronavirus variant and the progress of economic recovery.

Mortgage buyer Freddie Mac reported Thursday that the average for the 30-year mortgage edged up to 2.80% from 2.78% last week. The benchmark rate, which reached a peak this year of 3.18% in April, stood at 2.99% a year ago.

The rate for a 15-year loan, a popular option among homeowners refinancing their mortgages, fell to 2.10% from 2.12% last week.

In a fresh sign that the U.S. has enjoyed a sustained recovery from the pandemic recession, the government reported Thursday that the economy grew at a solid 6.5% annual rate last quarter. The total size of the economy has now surpassed its pre-pandemic level.

Another positive government report showed that the number of Americans seeking unemployment benefits slid last week, with jobless claims dropping by 24,000, to 400,000.
