It should be made clear that while there are many courses and training programs that specifically address REO Foreclosure issues, only the National Association of Realtors offers an official foreclosure certification. Companies like foreclosures.com offer a 'Certified Foreclosure Agent Program' however designations such as these aren't nationally recognized or a part of NAR.
NAR's Short Sales and Foreclosure Certification Program (SFR) was just introduced this year in response to the changing market and is currently the only recognized foreclosure agent certification. If your agent has a designation other than the SFR from NAR make sure to closely check their credentials. While some programs outside of NAR do an excellent job at educating and preparing agents to handle foreclosures, others hardly teach agents anything of value.
