A real estate brokerage representing a buyer must do what is best for the buyer.
A written contract called a buyer representation agreement, creates an agency relationship between the buyer and the brokerage, and establishes buyer representation. It also explains services the brokerage will provide, establishes a fee arrangement for the REALTOR®'s services and specifies what obligations a buyer may have.
Typically-buyers will be obliged to work exclusively with that brokerage for a period of time. Confidences a buyer shares with the buyer's agent must be kept confidential.
Although confidential information about the buyer cannot be disclosed, a seller working with a buyer's agent can expect to be treated fairly and honestly.
