A real estate company must do what is best for the seller of a property. A written contract, called a Listing Agreement, establishes sellers agency. It also explains services the company will provide, establishes a fee arrangement for the REALTORs® services and specifies what obligations a seller must have.
Confidence a seller shares with their REALTOR® must be kept confidential from potential buyers and others. That REALTOR® must tell the seller anything known about the buyer. For instance, if the REALTOR® knows that a buyer is willing to offer more for a property, that information must be shared with the seller.
A seller must understand that a REALTOR® working with a buyer as a sub-agent is ultimately working with the sellers best interest in mind. A REALTOR® working with a buyer, as a Buyer Agent, is working for the buyers best interest mind, but may still be compensated by the seller through provisions made to the Listing Agent.
