The buyer agent may be compensated by the purchaser, the seller and with the informed consent of both parties, by both. Buyer agents enjoy the same access to properties for sale as do listing agents and sub agents. Listing agents represent the seller and are responsible for the successful marketing of the property. They may work with purchasers but still represent the interests of the seller in negotiations. Sub-agents may be associated with other firms and also work with purchasers but represent the interests of the seller.
Sellers compensate listing agents and sub-agents for their services.
When dealing with purchasers both the listing agents and sub-agents are required to treat all parties fairly. The prospective home buyer has a choice when purchasing a home. He may either enter into a written contractual agreement to be represented by a buyer agent or elect to accept the services provided by listing or sub-agents of the seller. In one case you have representation and in the other you have assistance but not representation. But in either case you can be assured you will be treated fairly.
