Why you should use an Accredited Buyer's Representative (ABR) Why should you look for the ABR designation before looking for a home? These three letters after a REALTOR's name tell you that you will be working with buyer representative who is committed to your best interests. The ABR designation is awarded by REBAC to those REALTORS who have met the specific educational and experiential criteria needed to provide the high level quality service required by REBAC (Real Estate BUYER'S AGENT Council). A buyer's representative represents the consumer who is purchasing property, not the seller. A buyer's representative works for and owes fiduciary responsibilities to the real estate buyer. It is the buyer representative that has buyer's best interests in mind throughout the entire real estate transaction.
