A property dealer serves as a middleman between a buyer and a seller of real estate. In a person's lifetime, there are hardly any real estate transfers. So whether purchasing or selling real estate, a person might gain from the dealer's experience. A dealer is someone who buys a product for their business, stocks it up and then sells them off the rack. They act as a middle man between the distributor and the customer and act as authorised sellers of those commodities in a particular area.
