A seller talks with three different agents to establish a probable selling price for a home. The first agent's market analysis suggests a price around $79,900. The second agent's market analysis suggests approximately $81,500. The third agent doesn't research any comparables but simply lists the home at $91,500. Three months later the property sells for $76,900. What duty to the principal has the third agent breached?

Loyalty refers to an agent's obligation to act in the best interests of their client, avoiding conflicts of interest. While loyalty is crucial, the third agent's breach in this scenario is more directly related to their lack of reasonable care in assessing the property's value rather than a failure in loyalty.

Disclosure involves informing the client about important information that could affect their decision-making process. While the third agent may have failed to disclose relevant market data, the primary issue here is their failure to conduct proper research, which falls under the duty of reasonable care, not disclosure.

Accounting refers to the agent's responsibility to accurately account for and manage a client's funds and transactions. In this case, the third agent's breach does not pertain to financial management or record-keeping, but rather to the quality of their market analysis and advice, which relates to reasonable care.
