Ask for letters of reference, brochures and videos from previous sales. Select a real estate auction marketing organization, not just a general auctioneer. Avoid learners, amateurs & auctioneers who ask for large "up front" fees. Be sure your auction professionals are members of the National Auctioneer Association & the National Association of REALTORS. Look for professional designations from both the real estate and auction marketing professions, such as GRI (Graduate, REALTORS Institute), CRB (Certified Real Estate Brokerage Manager), CAI (Certified Auctioneers Education Institute), and AARE (Accredited Auctioneer of Real Estate). Ask for financial references and investigate real estate brokerage/development experience and background.
