Wholesaling to a financed buyer

[Michael Campbell]

I have a house under contract. I was going to wholesale it to a cash buyer. Instead I found a guy that wants it but needs to finance it. His lender does not want to have any other party involved... i.e. an assignment contract. I was thinking that the buyer can just pay me to cancel the contract with seller and then get a new contract with the seller. Has anyone ever done this and would anyone have an agreement that could be used to do this?

Thanks 

Mike
