Markets
Search public parcel records on a map: owner and mailing address, market value, acreage, land use and assessment history. The data is each county's own appraisal roll, not an estimate. Free, no account, nothing to install.
A roll names an entity per parcel, which is not the same thing as an owner. One operator files as forty single purpose LLCs and reads as forty small holders. Prospector resolves those back into footprints, from the county's own records, so you can see the whole holding rather than the one lot you clicked.
