Paper work for rent to own in question

[Lubasha White]

I have fixed house that did not sell for price I expected. I took it off the market and looking for short term tenant or rent to own with high down payment and goal to sell it eventually by the spring time. Just met prospective tenant that asking 6 months lease, makes 5k monthly but no sufficient credit due to divorce he is going through right now. He has couple kids that will live with him. Could anyone help with hint how to set up agreement in that case and where can I find the sample of this kind of agreement?

Any help would be so appreciated!
