That’s about right. Plop a house in the smackdab middle and let the undergrowth expand. Put in a pack of wild boars to patrol the property, grab some trained rotties to protect you from the boars, get the gun emplacements settled, barbed wire, electric perimeter fencing… sounds like a good place from which to watch the world burn. :)
Unfortunately, this is probably easily explainable there’s a choice of “acres” or “square feet” on the data-entry form, and someone typed 10,018, which is a believable number of square feet, into the “acres” block, and the database duly spit out that number, subject to rounding.
Update: County Assessor lists this tract as 0.2300 acre, which is a hair over 10,018 square feet.
