Real Estate One began in 1929 when Staunton Elsea established Elsea Realty in Detroit. The company grew through family leadership, with Richard Elsea merging multiple firms in 1969 to form the current brand. Subsequent generations expanded operations through strategic acquisitions like Max Broock Realtors in 2002. Today the company maintains a strong presence in luxury markets while serving clients statewide. Their business spans residential sales, commercial brokerage, and property management across Michigan's diverse regions.
