So I was recently told of this house.
It appears that it was bought in 1987 or 1988 by 142 Q St NW Inc... might have been before LLCs were a thing, for what looks to be $80,000. And it looks, because I'm scanning, not really reading the documents, like it was bought at auction. So it has been owned by the owners for a very long time. The owners, are located in Plymouth, NC.
Looking at the tax database, this property is not charged at the Class 3 - Vacant rate. Another quick scan of the documents and maybe there is some legal problem as there are trustees attached to it.... I dunno. Going back to 2005 it looks like they've been charged the normal rate for this multi unit (2 units as far as I can tell) semi-detached townhouse.
From the street it just looks like a duplex that is a tad shabby.
There is another house on the block that looks more vacant than this one. I may do it next.
