Real estate brokers and sales agents help clients buy, sell, or rent properties. Brokers and agents do the same type of work, but brokers are licensed to manage their own real estate businesses. Sales agents must work with a broker. Due to the complexity of buying or selling a home or commercial property, people often seek help from real estate brokers and sales agents. Although most real estate brokers and sales agents sell residential property, some sell commercial property, and a small number sell industrial, agricultural, or other types of real estate.
