Can I search Washington County by lot size or acreage?
Yes. Acreage is on 81 percent of Washington County parcels, mapped from the parcel boundary, and the advanced search filters on it directly - set a minimum and maximum to pull every tract in that range, then stack vacancy or absentee ownership on top.
