Wholesale deal listed on the MLS

[William Klawitter]

I have a property under an assignable contract with the owner at 15k. I've listed the property on the MLS, and someone's ready to write an offer at 25k. I'd like the owner NOT to see the price that I'm selling at (no need to rub the 10k assignment fee in his face) - is there a way to do this? How should the CAR purchase agreement & escrow instructions be written to accomplish this?
