Have you ever shaken a wrapped present to guess what's inside? Well, that's what happened to mortgage rates this week. They bounced around as markets wondered if the Federal Reserve will give us a rate cut at its next meeting.

The average rate on the 30-year fixed-rate mortgage fell eight basis points to 6% APR in the week ending Dec. 4, according to rates provided to NerdWallet by Zillow. A basis point is one one-hundredth of a percentage point.
