Once it's out of your hands, you have no say, sadly. When we sold our previous house, my wife told the people not to rent it, like that is even any of her, or our, business. Funnily enough, that's just what they did! And it was a facility for kids with Mongolism. The neighbor husband on the west side of us was a complete essobee, always on drugs and causing us problems. I hope that those kids gave him a giant bleeding hemorrhoid for all the crap he pulled on us!
Karma, baby!
