Suggestions on dealing with crazy neighbor

[Derek Daun]

We have a crazy neighbor next to one of our rental properties. And when I say crazy, I mean the term literally. Last night she was yelling and screaming at our tenants from outside.

I bought the house in 2015. At that time the house next door was boarded up, and I saw that as a good thing. (We get our house cheaper, and based on the neighborhood, a boarded house is likely going to get snapped up to flip. I thought I might even by it) Eventually I meet the owner and it turns out no dice. She inherited the house which is almost paid off, and her kids were raised in the house as well, leading to high psychological attachment to the property. In talking to her, it didn't sound like she had the mental capacity to deal with a house though, hence it was boarded up.

Fast forward to six months ago, when the owner converts the house into an assisted living rental for the mentally disabled. That's a common scam slum lords pull around here, as it's a good way to milk the city for money. This soon becomes an issue, as the owner can't handle being that type of landlord. When ever she'd come over, she start screaming at the residents, causing them to come next door asking for help. The police have been called multiple times by other neighbors (not my tenants). The owner is now upset at people living on the block now, since the police were called leading to last nights confrontation, which lead to my tenants actually calling the police.

Any thoughts?
