I've just been renting it out to long term tenants, but I'm wondering if I can legally do short term rentals (AirBnb) even if it isn't owner-occupied since it's zoned for commercial use?

The roof, I’m not sure if it’s bad, but will payout of my own pocket for an independent inspection But the standard Minnesota c4d gives the seller soooooo..... many ways for the owner to “screw me” out of repairs and legal fees paid to him for repairs.

Is legal for an landlord to live in a finished attic or basement and rent the 1st and 2nd floor of a 2 family house in NJ?

No legal advice here. 

Whom ever filed it will be your first point of contact.The property is going to have to be probated in order to legally change ownership.

I tried over on the Legal and Contracts forum but didn't get any replies (https://www.biggerpockets.com/forums/51/topics/611...).So I'm trying here.Would love to know if you know any good people. 

It's best in this situation to stick to the legal script just in case it backfires.There was a podcast episode that covered something very similar, can't remember the number or guest but it was a few years back. 

Hi Clifton,I am not a lawyer and this is not legal advice.

Just concerned with the aftermath if I file a legal suit against them.

I don't care who the wholesaler is - if the deal has opportunity, the paper is clean, and the transaction is legal, then it might be a good deal for some of us - but not for all.
