The San Antonio Board of REALTORS® (SABOR) was organized in 1910, by twenty-two members of the city’s real estate community who felt San Antonio would benefit from a collective membership of REALTORS®. Shortly thereafter, SABOR became affiliated with the National Association of REALTORS® and in 1920; the Texas Association of REALTORS® was formed under the guidance of SABOR. Today, the San Antonio Board of REALTORS® is one of the largest boards in the state of Texas with close to 7,000 members.

Only members of these associations can use the term REALTORS®. The term REALTORS® is not a synonym for "real estate agent." It is a distinctive and exclusive designation for those within the membership of the National Association of REALTORS®. The term connotes business competence and high standards of business conduct. Each member pledges to observe a strict Code of Ethics written by the National Association of REALTORS®. The preamble calls for every REALTORS® to work for the preservation of the free enterprise system and the protection of private property ownership.

The San Antonio Board of REALTORS® provides its members with the education they need to achieve the highest degree of professionalism in their fields. It is one of the few Boards in Texas that is certified by the Texas Real Estate Commission to operate a real estate school. All the courses offered are accredited for broker or salesman licensure. In addition, SABOR’s various committees present seminars covering all areas of real estate from financing to equal opportunity in housing.
