Wholesaling Closing Questions

[Chris Graf]

Hello

I am about to put in a offer to a home that is currently going on 2 months mortgage past due, I got off a direct mail campaign. I want to put it under contract and then sell the contract to a cash buyer rehabber for a profit. Before I Sent a offer I wanted to clarify the process. After I send the offer and if It gets accepted, how do I determine the down payment? One other question how do I get the profit off the sell of contract?
