Which of the following is NOT a function of a real estate agent?

Setting tax rates falls outside the responsibilities of a real estate agent. Real estate agents primarily focus on facilitating transactions and serving the interests of their clients in buying, selling, or leasing properties. Their functions typically involve advising clients on mortgage options to help them navigate financing, marketing properties to attract buyers or tenants, and representing clients during negotiation processes to secure the best possible deals.

In contrast, tax rates are established by government authorities, and while real estate agents may offer some guidance on how taxes might affect property transactions or provide general information about property tax assessments, they do not have the authority or responsibility to set tax rates themselves. This delineation of authority is crucial in recognizing the true scope of a real estate agent's role.
