A broker's obligation to their client includes:

The role of a broker encompasses several ethical and legal obligations toward their client, one of the most crucial being the duty of confidentiality. This obligation means that a broker must protect sensitive information shared by the client, such as financial details, motivations for selling or buying, and personal circumstances. Maintaining confidentiality fosters a trusting relationship, ensuring that clients feel secure in sharing pertinent information that may affect their real estate transactions. This duty extends beyond the transaction itself; it usually lasts indefinitely, even after the professional relationship has ended.

The other aspects, while important, do not encapsulate this fundamental duty. Providing an opinion on property value can be part of the broker's role, but it does not carry the same level of obligation as maintaining confidentiality. Advising clients to make a fair offer is a professional courtesy that supports ethical practice, but again, it is not a core duty as confidentiality is. Competing with clients for better offers contradicts the broker's responsibility to advocate for their client’s best interests and would not be considered a valid obligation. Thus, the confidentiality duty stands out as a critical and defining element of a broker's responsibility toward their client.
