Interest in a neighboring home

[Cory St. Esprit]

We live in a small town outside Pittsburgh. We own our primary, own a STR internationally, 3 commercial buildings, and a 4-unit apartment building - so we are highly familiar with real estate but here's a new conundrum. Across the street from our primary residence, a company bought a house as a rental and it's been nothing by problems. They're basically slumlords and the police are often called there - resulting in tenants coming and going a lot (our town has a 3 strikes and you're out policy on renters). They don't care about the house.....how do I contact them saying I want to buy it? We have a nice group of us investing in our own homes and want to see the neighborhood do well. I just don't know how to contact them and basically say "You suck - I want to make our neighborhood nice so please sell me your home.'

Two tenants ago was so terrible and when the police showed up one night I got to talking to them. They said "Just so you know - call us for anything because of the three strikes and you're out policy." I said I didn't want to bother them with petty things and they said "We know the types of tenants this guy is putting in here, so if you feel even slightly inconvenienced, please call us." 

Call me petty - that's fine. But I'm raising my 4 kids in this home with my wife, grew up in the area, want to see it do well - so I will continue to call the police on things I see there...which most likely will result in the landlord having an ongoing slough of tenants in and out. So...having never met the landlord but I do know their primary address, how do I go about letting them know I want to buy it?
