2 escrow accounts with a double close??

[Rob Shipley]

So here's my situation. I have an old house I have under contract I'm paying cash for and planning to flip and hold. I decided to put it on Craigslist prior to close and just see what would happen. Low and behold I have a cash buyer for my asking price. I didn't plan on it being a wholesale deal but it turned into one! So now to ensure this guy will close ... can I open up a separate escrow and put his earnest money in it even though I don't own the house yet?? Obviously he wont let me just keep his earnest money myself. Or do I just have to hope he shows up to the double close with the full funds? Thanks for any help!
