buyers choose finishes?

[Jeffery Waicak]

has anyone ever tried this? basically do the rehab 100% on the outside,so it has nice curb appeal. do all work inside to the point where you have drywall up and primed white. then market as starting at your lowest price with builder's grade finishes or better depending on buyer's budget and taste. have them sign a contract and give a sizable deposit and finish to their liking?
