- 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.
