Mortgage rates are a smidge lower compared to last week, but it's likely not enough to spur homebuyers off the sidelines.

Mortgage rates are having a dramatic month—falling, surging, and falling again. Rates have now changed direction yet again, with most loan averages moving higher.

Mortgage rates decreased marginally this week, said the latest Freddie Mac Primary Mortgage Survey. 30-year fixed-rate mortgages averaged 6.81% as of April 24, down from 6.83% last week and 7.17% in the year-ago week.
