Sell Rehab Before Completion

[Ryan R.]

A lady walked inside my rehab yesterday while I was installing some window casing. She was interested so I gave her the tour. She told me that, " you might have just sold this house". I've heard this throughout my career, being in Marketing & Sales, and didn't take it too seriously. She came back today with her realtor and made an offer.

She wants to structure the deal so that she gives me $100,000 on Friday and close that day. The remainder of the sales price will be in an escrow account until completion. My concern here, are problems creeping up that are not in our soon to be scope of work.

Should I instead ask for a non-refundable deposit, much less than $100,000 and then sign a contract that doesn't close until completion? What's the best way to structure this deal?
