Mortgage rates were almost perfectly flat today, and have been largely unchanged since last Friday. If you were forced to predict such a thing at the end of last week, the odds would have been in your favor. In other words, when rates are on the move, Thanksgiving week tends to see a temporary pause in that movement.
Bond markets and mortgage lenders will naturally be closed for the holiday tomorrow. They will technically be open on Friday but participation will vary widely. Many lenders won't update their rate sheets. Others will only make token changes unless financial markets are unexpectedly wild. The following week should see market and mortgage rate activity pick up again. Happy Thanksgiving!
