I have listed wholesale properties on the MLS with an agent/broker.
Once in a while, I find a a wholesale deal that I call a tweener. This is a property that is somewhere between a rehab and a turnkey property. My usual buyer's sometimes pass on deals and I will try to find other buyer's using the MLS. It works pretty well too.
As J Scott has already said, you will need to meet with broker's in your area to determine whether that association will allow this type of listing. Check with the smaller broker's first.
But, also very important, you should have a very good reason for listing the property as I agree with what Jon has said, your better off with a cash buyer becasse a lender will not generally finance a property being from someone other then the owner of record.
For instance, light rehabs with small margins may not be enticing to your usual buyer's, so you should still target investors or handymen with cash or hard money. There are a lot of buy and hold investors that like light rehabs.
Good Luck!
