I would have each party pull there own LLC and become investors using there own. 

All "related parties" are counted together. 

Then you have some kind of 3rd party documentation to prove it needed to go and you were removing it for safety reasons.If you move a mobile to it, chances are you need to install septic.....so that's $10,000 probably.   

The people renting wouldn't be here to party. 

Is there a cancellation clause in the contract for either party?

You are licensed and need to disclose that to the other parties in the transaction as well as run the deal through your brokerage, unless your employing broker says otherwise.

My understanding is that both parties who are entering into the lease agreement need to be clearly stated...lessee and lessor, without that it is not a valid contract.

Of course you then run into the issue that the remaining party wants to either break the lease and leave as well or bring in a new roommate so they can afford the place.

The most complicated part is the sale and purchase through a third party called a QI, qualified Intermediary.   

But the tough part is that we don't know where to look online to verify that the county/ city would permit us to conduct business.
