Assuming an agreement with the listing broker as regards cooperation and compensation, you may represent the buyer as an exclusive agent. You cannot be appointed by the intermediary because you are not an associate of the listing broker, and from the facts as you describe them, no intermediary status is going to arise. Confidential information obtained from the seller when you were acting as the seller’s agent, of course, could not be disclosed to your new client, the buyer.
