Reaching out to owner of potential BRRRR property

[Leonard Leon]

So i've been searching on here to figure out how to find the owner of what looks like a super run down property or even a potentially vacant property. But after that i've come to a stand still as I don't quite know how to reach out to them. Since that residence looks vacant it would make no sense sending out letter stating I would like to purchase the property. So i'm looking for some help if anyone else knows a way of maybe finding their phone number or another way of reaching out them. 

Thanks!
