A broker is showing a home to a buyer and recommends that the buyer not make an offer on the property because it is not a good fit for the buyer's stated needs. The buyer later discovers a much better property and purchases it from another agent. Under what agency duty has the broker failed?

Obedience refers to the broker's duty to follow the lawful instructions of their client. In this scenario, the broker did not disobey any instructions given by the buyer, as the buyer did not direct the broker to pursue a specific property. Therefore, the issue here is not a failure of obedience but rather a failure to provide suitable advice.

The duty of accounting involves the broker's responsibility to keep accurate records of all funds and transactions related to the client. This duty is not relevant to the situation described, as there was no financial transaction or mismanagement of funds involved in the broker's recommendation against making an offer.

Disclosure pertains to the broker's obligation to inform the client of all material facts affecting the property or the transaction. While important, this duty does not apply in this case, as the broker's failure was not about withholding information but rather about the lack of appropriate advice regarding the buyer's needs.
