GROSS OFFER Buyer to pay 'All' Closing costs even Xfer Tax! Okay?

[Jonn Vidal]

Is that ok at NY closing table or is Cash Buyer just fluffing?

I'm thinking hmmm what about say (besides commissions if any): Closing attorney, Property Tax Adjustment (usually $500?) and that thing where you 'have' to credit buyer 500 if was selling as-is where is etc ie not fully completing property condition disclosure document, etc? Not sure what to consider their offer, is there a term for that, ie 'Flat' offer, 'Gross' (or net?) offer, or what? 

And is it permissible? Know Net Listings aren't.. but what about Gross Offers like this?
