@Timmy Fritz, if you're looking at owner financing, that can be whatever you agree to with your mother (within reason and the law).

The terms of your lease contract and the landlord-tenant law for your jurisdiction will determine what you can do to settle the tenant's account.

If a wrap is being used, and the existing underlying note is not assumable, then the note holder can accelerate the note at any time, demanding a payoff in full in a time period compliant with the laws of the state the property is located in.Many states, like Texas have state forms in which the blanks can be filled in to be used for an offer on residential property.

What does the local laws say about trespassing..... but on a side note how you are going to enforce this?

Attorneys spend an entire semester in law school for the class. 

I need to start looking in AZ since its in my own backyard. don't confuse garden variety rentals and those tenant landlord laws.. with MHP tenant laws they are not the same. 

Just looking to bounce ideas with some experienced folks on here.My law firm has been expanding and has outgrown our current space.

You also need to understand landlord-tenant law better than your tenants.Understand tenant mentality.  

Typically, you would assign the contract to the buyer, the Buyer pays your assignment fee but your fee won’t be factored into the sales price for his financing.....possible issue with licensing laws depending on your state laws on how you market it.   

The law suit option came with the possibility of a counter-suit.
