Wholetail deal in Georgia - Contract Advice

[Stryker Brown]

My contractor brought me a deal that we are looking to wholetail (a first for me). We are putting under contract for $200,000 and will list for $250,000 to $260,000 with an agent. I'm assuming we are going to lock up with a typical psa/wholesaling contract and then complete a new purchase agreement with the end buyer and end with a double close. I have concerns on how smoothly this will go with a buyer that likely wont be paying cash. Have any of you had experience with this or have any advice on the most efficient way to structure this deal?
