Final answer:
Charlie should forward the offer to his seller client immediately, as he is obliged to communicate all offers and the property is still under the seller's ownership until closing is complete.
Step-by-step explanation:
Charlie should forward the offer to the seller immediately. Real estate professionals are obliged to communicate all offers to their clients unless specifically instructed otherwise by the client. Even if the property is under contract, the seller might have provided explicit instructions to Charlie to pass along all offers, perhaps in anticipation of issues with the current pending sale or simply for their knowledge. Moreover, until the closing is complete and the property is legally transferred, the seller retains ownership and should be kept informed of all offers. Charlie should not wait until after the closing to disclose the offer, and he should not discuss the offer with the buyer first, as his duty is to his seller client.
