A real estate broker, real estate agent or realtor is a person who acts as an intermediary between sellers and buyers of real estate/real property and attempts to find sellers who wish to sell and buyers who wish to buy. In the United States, the relationship was originally established by reference to the English common law of agency, with the broker having a fiduciary relationship with his clients. A real estate broker typically receives a payment called a commission for successfully matching a seller's real estate with a buyer such that a sale can be made. This commission can be divided up with other participating real estate brokers or agents when applicable.
