Where the parcel data comes from
The link goes to a statewide map (Tennessee Property Viewer (TN Comptroller)). It shows parcels for Obion County along with the rest of Tennessee. A statewide layer can trail the county's own books by weeks or months, so treat it as a fast first look rather than the final word. As of our October 2026 test, anyone could open it without signing in or paying.
How to use the Obion County viewer
- Open Tennessee Property Viewer (TN Comptroller) in a new tab and zoom to Obion County (around Union City).
- Type a street address into the search box, or click directly on a parcel.
- Review the parcel attributes; field names vary by state.

Maps vs. surveys
Treat the map as a guide, not a boundary survey: parcel outlines are often shifted a bit from the real corners. A licensed surveyor settles exact lines.
