What best describes the role of a broker?

The role of a broker is fundamentally about representing clients in real estate transactions. This involves guiding buyers and sellers through the complex process of purchasing or selling property, which can encompass various tasks such as market analysis, negotiations, and facilitating communication between parties. Brokers also have a fiduciary duty to their clients, ensuring that the clients' best interests are prioritized throughout the transaction.

In contrast, while property management, commercial transactions, and acting as a third party in rental agreements are aspects of the real estate industry, they do not encompass the broader responsibilities and duties of a broker. A broker's role is not limited to any particular type of transaction but rather encompasses all types of real estate dealings, making representation in transactions the most comprehensive description of their function.
