It takes more than a motivated seller to get a good deal or even a decent deal.No law enforcement agent or other agency is going to believe that you attempted to enter into any business transaction to help the owner, regardless of how you "feel" so don't even go there, making claims your proposed or closed deal was/is a win-win, falls on deaf ears and is an indication that something in the mix is predatory.

They usually never enforce it but if interest rates go up, it's always a possibility.

Enforce the 3 day pay or quit. 

You can however end up with special assessments, water and sewer, code enforcement and any other state or county or city lien, and not to mention IRS liens. 

You will need a strict lease and you will need to enforce rules: are you ready for that?  

., not a single parent or someone just struggling to survive then by enforcing the lease you are doing them a favor.  

I agreed to it once but added so many "out" clauses I felt safe as the contractor that it would not be enforceable.

If they are VERY professional, they will have their processes in writing as verification that it is enforced equally and fairly by their entire staff.6.

You have to enforce your lease. 

Should you fail to enforce the lease and ensure this right, your tenant can break the lease.
