Mortgage rates posted another all-time low this week, according to Freddie Mac’s Primary Mortgage Market Survey (PMMS).

The average 30-year fixed-rate mortgage has hit its lowest level in the nearly 50-year history of Freddie Mac’s market survey, down to 2.81% from 2.87% last week.

“Low mortgage rates have become a regular occurrence in the current environment,” said Freddie Mac Chief Economist Sam Khater. “As we hit yet another record low, the tenth record this year, many people are benefitting as refinance activity remains strong. However, it’s important to remember that not all people are able to take advantage of low rates given the effects of the pandemic.”

The 15-year FRM also fell this week, dropping to 2.35% from the average 2.37% the week before. Last year at this time, the 15-year FRM averaged 3.15%.

The 5-year Treasury-indexed hybrid adjustable-rate mortgage averaged 2.90%, slightly up from last week’s 2.89%. The 5-year ARM averaged 3.35% a year ago.
