Which of these is NOT typically a duty of a real estate broker?

The correct response indicates that creating new real estate laws is not typically a duty of a real estate broker. Brokers operate within an established legal framework and are primarily focused on facilitating transactions, managing properties, and representing clients in negotiations. While they might advocate for changes in legislation or regulations that impact the real estate market, they do not have the authority or responsibility to create laws themselves.

In contrast, the duties of negotiating contracts, providing property management services, and selling properties are all standard responsibilities for a broker. Negotiating contracts is a fundamental part of a broker's role, as they work to secure agreements that best serve their clients’ interests. Similarly, brokers often engage in property management, offering services that ensure properties are well maintained and meet legal and market requirements. Selling properties is, of course, the primary function of most real estate brokers, making it a core aspect of the profession.
