The Anderson Associates Private Client Group: Traditionally, all Realtors, whether listing or selling, represented the seller. Realtors were the seller’s agent or sub-agent. However, the rules of Agency (who the Realtor represents and what their duties are) have been changing rapidly over the last few years. It is vital that you understand this change and that you know whether you are a customer or a client. The obligations the Realtor owes you will be significantly different depending on which you are. Our Private Client Group represents buyers exclusively as their agent.
