How do I find vacant land or absentee owners in Westchester County?

Can I search Westchester County by lot size or acreage?
Yes. Acreage is on 100 percent of Westchester 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.
