No: Wisconsin's data here carries no homestead flag, so nothing in it says whether an owner lives in the property. What Tracer can filter is where the owner's mail goes: Out-of-state (a mailing address outside Wisconsin), plus company owners and owners of 3+ parcels.

There's no single-family count for Wisconsin: Wisconsin's property class 1 is every residential parcel (houses, duplexes and condos alike), so its roll can't single out single-family homes. The Single family filter finds almost nothing there, so count with the other filters.

Request Data offers the 70 Wisconsin counties whose rows in the state's data carry enough complete records; the other 2 don't yet. Tell us the county you need and we'll say what we hold.
