Realtor Mega-Merger Absorbs St. Lucie, Parts of Martin into Nation's Largest Group

A real estate power play centered in South Florida is about to reshape how thousands of agents buy and sell homes across St. Lucie County and parts of Martin County. Two of the nation's largest Realtor associations announced a full merger.

The Miami Association of REALTORS®, the largest local Realtor group in the United States with 56,000 members, and RWorld, the third largest at 37,000 members, confirmed their combination into a single entity to be known as Miami and South Florida REALTORS®. The merged organization will claim 93,000 members — a number larger than 47 individual state associations and more than double the next-largest local association in the country, public filings indicate.

For Treasure Coast agents and their clients, the practical consequence is membership in what will be the largest multiple listing service owned by a single U.S. Realtor association. That MLS footprint explicitly covers Miami-Dade, Broward, Palm Beach, St. Lucie and parts of Martin counties — meaning agents working deals from Stuart to Fort Pierce will operate under a significantly larger data and technology umbrella.

The two groups reported a combined $69 billion in total real estate volume in 2025. Members will gain access to two MLS platforms, Flexmls and Matrix, along with more than 2,830 annual educational seminars and over 300 marketing tools.

Teresa King Kinney and Dionna Hall will serve as co-CEOs of the new organization, continuing what officials describe as more than 60 years of consecutive women's leadership. Division structures for both legacy organizations will remain intact: Evian White De Leon will lead the Miami REALTORS® Division, and Kim Hansen will oversee BeachesMLS and the RWorld Division.

For buyers and sellers navigating an already-complex Treasure Coast market — where inventory constraints, elevated insurance costs and in-migration from South Florida have driven persistent price pressure — a larger shared MLS could mean broader listing exposure and faster deal velocity. Whether that translates to lower transaction costs for families in Port St. Lucie or Jensen Beach remains to be seen.

No completion date for the merger was disclosed in public documents, and terms of the agreement were not released. Agents in St. Lucie and Martin counties seeking specifics on how their current MLS access will transition should contact their local board directly, officials said.
