Hi Dorothy, an Agent has certain Fiduciary duties to a client (A fiduciary duty is the highest standard of care possible). These can be boiled down to Loyalty, Obedience, Diligence, Disclosure, Accountability, and Confidentiality. The Listing Broker works for the Seller. He has no obligation to keep information you tell him as confidential, in fact, he has a duty to disclose information material to the transaction to the Seller.
This is a perfect example of where a Dual-Agency can introduce conflict. To avoid this conflict of duties, a Dual-Agent may not place either client into a beneficial position over the other. For example, a Dual-Agent can provide the price of a home but canâ€™t provide advice as to the appropriateness of the price. Another example might be where a Dual-Agent performs a Comprehensive Market Analysis. The findings can be shared, but not interpreted to either client.
