I know he'll lose his $44K deposit and probably owe the listing agent her commission of $34K, correct?
I can't imagine how any Contract would have been drafted that has the Buyer owing the Listing Agent anything ?
The P&S is a Contract between the Buyer and the Seller.
The Listing Agreement is a Contract between the Seller and the Listing Broker.
The Buyer Representation Agreement (if there is one) is a Contract between the Buyer and the Buyer's Broker.
Under which Contract would the Buyer be paying the Listing Agent anything? . . . The Buyer typically receives NO SERVICES from the Listing Agent; therefore he owes that Party no Compensation.
Of course, the Buyer loses his/her Earnest Money Deposit to the Seller (he may also be liable for a breach of Contract Suit); and he may owe the Buyer Broker something (depends on the wording of the EBA) . . . . but he never signed any Contract where the Listing Agent and the Buyer are both Parties to the same Contract.
