20What this does and does not say
- Coverage is the areas EuKreate tracks, so this is not the whole of St. Clair County.
- Active asking prices only, not sold prices and not an appraisal. Check official sources before acting.
- Whether a home is under contract is not in the data we receive, so no pending count is shown.
- An area needs at least 8 active listings before a median is shown, because a median of four is a number rather than a market.
- Measured September 21, 2026 and recalculated daily.
