This must be taking a toll to on yours and her relationship.This is why I never, ever do business with family or friends.When things go downhill, now you have to deal with seeing them at company holiday dinners, ugghhhh.I am not familiar with the NY landlord-tenant laws but know that, should this be processed as an eviction, what you are doing currently whether or not it shows up in court is not right and legally could work against you.Trust me, I really do empathize with you and your situation and it seems like this Brother in Law is really taking advantage of you, but don’t correct this wrong with another.Follow the legal process to get him out, talk to your wife to see if she can intervene at all, but it seems he may not listen to her either and just does not care.So my laughter is because I cannot for the life of me see how someone can think that this kind of behavior is right to do to anyone, leave alone your family.This man/boy should be ashamed of himself for putting you and your wife/his sister through this mess.After this, I suggest you be very careful about inviting family over for those extended stays that never seem to end.

I see way too many out of state investors get lied to and buy an over priced property and then fail to maintain it and it goes downhill fast.

It's sad, because they really seemed to love living there and were otherwise the ideal tenants.I've dug around on the city and county websites a bit, but I can't find his name in any of the booking records for the past week or so.I know that, by the books, I should serve a notice to start the eviction process to cover me if everything goes downhill.

That inspection is where things went downhill fast.

I'm tempted to see what their bottom dollar would be but I don't want my first deal to go downhill because of the oil tank.
