Market.
Market type is set by months of supply — how long it would take to sell every home for sale at the current pace. Under ~4 months favors sellers (low inventory, faster sales, homes near or above asking); over ~6 favors buyers (more choice, more negotiating room). 4–6 is balanced.
Months supply.
How many months it would take to sell every home now for sale at the pace of the last 90 days: homes for sale ÷ (closings in the last 90 days ÷ 3).
Median list.
The middle asking price among the homes for sale right now. Half are listed above it, half below.
Days to contract.
The middle number of days between a home being listed and going under contract, over the last 90 days of closings. It is not days-to-close, and it is not how long today's listings have been sitting. Newly built homes are excluded, because a build finishing is not a market moving.
