My wife and I are looking at a property in her home town back in NC. Can't move there yet, but doesn't mean we can't buy the right property now.    It's being advertised as a 30 acre property, and when I look it up on the county's GIS, it does say 30 aces. However, it also has a calculated acreage that says 26 acres. If you draw on the property using the tools on the site, it does say 26 acres.   Anyone know the reason for this discrepancy? Would I be getting 26 or 30 acres?
