Wholesaling REO question

[Leonard Knight]

Hello everyone, I'm in need of some advice on wholesaling REO properties when using transactional funding. How do you get your cash buyer to fund the deal by putting their money in escrow before the transactional finder gives you the proof of funds letter? In order to make anything on the deal, you'd have to mark the price up, correct? What will stop the cash buyer independently looking up the property and seeing he actual price? And from there buying it directly from the seller...I'm snagged up on this. Any advice would be appreciated. Thank you, Leonard
