If doesn’t successfully close, how much does escrow charge. And who gonna pay for it? Thank you very much.

The sales contract should specify who pays escrow charges.  

My understanding is if a deal falls through and does not get completed...escrow does not get paid. Im currently in escrow and within 2 weeks we were going to cancel. At that point they already had my earnest money. I talked to my reator and they said that no one pays anything to escrow if it falls through. I don't see a difference whether its 2 weeks or 3 days before closing in that sense.
