REBAC founded in 1988 focuses on buyer representation. While it is now a broadly-accepted, mainstream business model in real estate circles, it’s sometimes easy to forget that it wasn’t always so -and how quickly the shift occurred. Within the National Association of REALTORS® (NAR), buyer representation officially took hold in November 1996, when NAR acquired the then-independent Real Estate Buyer’s Agent Council (REBAC), giving full support to a trend that had been gaining momentum throughout the 1980s. REBAC has enjoyed exponential growth and is the largest of NAR’s Institutes, Societies, and Councils, with active REBAC members spanning the globe, with nearly three quarters holding their Accredited Buyer’s Representative (ABR®) designation. REBAC’s course provider network - the many real estate associations and schools that offer REBAC courses - is equally or even more impressive, encompassing and extending well beyond the U.S. More than 136,000 real estate professionals have participated in REBAC-sponsored education.
