Short Sell Counter Offer?

I'm not really sure of all the abbreviations you have used here but let me tell you this. You are the buyer, therefore you are in complete control over the seller. The seller wants YOUR money so you tell him what he needs to do to get it. Don't compromise, the seller knows that at any second you can walk away from the deal and he doesn't want that to happen. Understand? Go get yourself the deal of a lifetime.
