(copyed from website)It looks like this is for a production facility,  I am no legal analyst. but if I thought the house was used in production, I would  just pass on to the next buy,  Now with that said. how do you know the history of any house I buy?

I did not know that .. again got tagged for that 1k fine  get the license now all legal.. but 90% of the folks who may take a guru how to flip homes courses this wont be covered in this state.. and they are actively fining folks. 

Your legal options are based on your lease...If they were good tenants and the place is in good shape, I would do everything possible to start marketing it right away before the current tenant moves out.

Now, if you could get him to sell you the house, after which you could sell as a principal—that is legal.

If you invest everything in purchasing note, how will you pay legal fees, taxes, etc if you have to foreclose?

Worst case is you get nothing.I'm not a lawyer and this is not legal advice, but here are some reactions to what you stated in your post:If you can prove you actually paid the yard guy, and the landlord can't prove he did, you have a good argument on that line item. 

or assigns" wording may make it legal, but for a seller who doesn't understand, does that make it right?

Idk about the legalities there so I'm going to suggest an attorney.

"A Trust name is not party to a contract, it is not a legal person as a corporation is.

Even making a rock-bottom offer doesn't sit well with me sight unseen.This is in Iowa, but I am wondering if anyone knows the legal rights I would have if an offer were accepted with these tenants already in place?
