ENTIRE AGREEMENT AND MANNER OF MODIFICATIONS.

It conveys an ownership interest as much as conveyance of title by contract terms for the use of the property, encumbrances, modifications of improvements, taxes and insurance as made by contractual agreement.

If it truly is an ESA, then make sure you do your research on it before you respond.Since your tenant is asking for a modification to the the existing lease (adding an occupant), I think you'd be able to deny that modification if you'd like and they would be bound by your current agreement until expiration. 

If you purchase for 805k how is an appraiser going to justify it is valued at 950k without some serious modifications?

You cannot make any modifications without the tenant agreeing to it.
