Market Narrative
The market has been cooling off a bit in recent weeks, as more homes are available and demand is less. We’re already seeing prices move lower as a result. Expect this trend to continue especially if the index falls to the Buyer’s zone. Watch for a persistent up-turn in Market Action to signal prices rising again.
