What this does and does not say

  • Coverage is the areas EuKreate tracks, so this is not the whole of Union 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 20, 2026 and recalculated daily.
