Need Help with possible sub 2

Hello all:

I need some help with what would be my first sub 2 if it works out. The owner who I am dealing with has a house in Florida he wants to sell but he lives in Georgia. I have already verbally explained how a sub 2 deal would work to the best of my ability but I would like to ask to all who could help me on this board what exact paperwork would I need to get the deed for a sub 2 deal. I live in Florida as well. He asked me the following questions via email and I would like to be able to get back to him as soon as I can:

Can you give me any other details of what contracts you will need signed? Would we need to come down there or can I have my lawyer handle everything from here? Can you send me a copy of a contract to review?

Thanks very much in advance
