Final answer:
John Jamison breached his duty to his clients by disclosing their minimum acceptable price to a buyer without express permission, thus violating his fiduciary relationship.
Step-by-step explanation:
John Jamison, a salesperson with Taylor Realty, lists the property of Charles and Loretta Simpson for sale at $52,000. However, taking into account that the Simpsons are pressed to sell and would accept $49,000, Jamison informs a prospective buyer, Rand Evans, of this lower price. In this scenario, Jamison has violated his relationship with his client by not seeking to obtain the best possible price for the property, which breaches his duty of loyalty to the clients. As a professional salesperson and fiduciary, Jamison should keep his client's financial interests paramount and not disclose the minimum price they would accept unless expressly authorized to do so.
