A developer or builder offers a prospective purchaser a financial incentive in exchange for agreeing to a future listing to sell the home through a real estate agent or broker with whom the developer or builder has a relationship. Upon making the agreement, the developer or builder provides the agreed upon discount and provides the referral to the real estate agent or broker that has been chosen by the prospective purchaser. The real estate agent or broker has agreed to pay a referral fee when the future listing results in sale of the home. When the purchaser decides to sell the home, the home is listed with the real estate agent or broker. When the sale of the home is completed, an agreed-upon referral fee is paid to a middleman who takes a commission and gives the rest to the developer or builder. The middleman has created a list of real estate agents or brokers from whom the prospective purchaser can choose a desired agent or broker. The middleman creates a data base that permits monitoring of any and all transactions that might occur vis.a.vis homes that are subject to the future referral agreements.
