worth noting: clarksville is a very high income area. i have family in Columbia (nearby). probably just some rich ahole.
Some of the most expensive homes on the East Coast are located in or around the town, whose property values are among the highest in the country. According to the U.S. Census Bureau, Clarksville District 5 has a population of 56,239, with an estimated average income of $195,124, with median income of $160,606.
Honestly that doesn't look too different from the house my grandparents lived in. The kitchen, living room, one bathroom, and one bedroom were in good condition and the rest was crumbling plaster exposed beams and lath. The place was huge probably 6000+ sq ft and they just didn't give a shit. It was a fun place to explore as a kid. It smelled like old magazines.
That would make for one nice house with another 500,000 put into it. Our house was not that bad but not far from reaching that state when we bought it as it was raining through the roof which they tried to fix with trap on the floor in the ceiling but that was our luck so we could afford the place as there were nobody who wanted to buy.
MIL's place... Oh boy. The shit they've found since they opened the walls up. Damage to a drain line, likely back to the earthquake in '89. All the mold? Yeah, that goes back to MIL not having someone out to actually inspect it because she was too embarrassed to see her place. It should have been fixed and paid for by HOA insurance 30+ years ago. She should have gotten $425k+ for that place, because the majority of the depreciation losses were related to the water damage and mold.
