Coldwell Banker Commercial S.A. owned by Charles W. Kelly, MAI was originally franchised in 1998 by Steve Stringer. Mr. Kelly started in commercial real estate as an appraiser in Kansas City in 1973. He moved to Texas in 1984, to work at Merrill Lynch’s Commercial Real Estate Advisory Group and later with the Institutional Investment Banking Division. Charlie operated his own appraisal and advisory company for 10 year and then joined Coldwell Banker Commercial in 1998. Mr. Stringer sold Coldwell Banker Paula Stringer Residential in 2000 and in 2003 he agreed to sell Charlie the Coldwell Banker Commercial S.A. entity.

For most of its 100-year history, Coldwell Banker Commercial offered both commercial and residential real estate services. But in 1981, Sears, Roebuck & Co. purchased Coldwell Banker Commercial and, eight years later, sold the commercial side to a group of employees and investors now known as CB Richard Ellis. At that point, the residential group entered into a "non-compete" agreement that prohibited Coldwell Banker from providing commercial real estate services for a period of five years, ending in 1996. Coldwell Banker Commercial, as part of the Parsippany, N.J.-based Cendant Corp (now REALOGY), re-entered the market in 1997, and has since grown to over 450 offices with nearly 5,000 agents.
