Freddie Mac’s most recent Primary Mortgage Market Survey shows the 30-year fixed mortgage rate dropping to its lowest mark since November 10, 2016.

“The 10-year Treasury yield fell 6 basis points this week amid concerns over lagging inflation,” says Sean Becketti, Freddie Mac’s chief economist. “The 30-year mortgage rate also declined for the fourth consecutive week, dropping 3 basis points to a new year-to-date low of 3.86 percent.”
