MIAMI REALTORS has completed its second merger in two months, absorbing Martin County REALTORS of the Treasure Coast and extending a newly unified association across a nearly 120-mile real estate corridor from Miami-Dade County to St. Lucie County. The combined organization counts roughly 94,000 members, making it the largest local REALTOR association in the country — bigger than most state associations.
The merger, announced July 23, follows the May combination of MIAMI REALTORS and Broward, Palm Beaches & St. Lucie REALTORS, known as RWorld — a pairing of what were then the first- and third-largest local REALTOR associations in the United States, according to the National Association of REALTORS. With Martin County now folded in, the association’s footprint spans Miami-Dade, Broward, Palm Beach, Martin and St. Lucie counties.
One membership, one MLS ecosystem
For agents, the practical stakes are in the listing data. The merged organization operates what NAR describes as the third-largest multiple listing service in the country, giving members access to both the Flexmls and Matrix platforms, free IDX feeds from the MIAMI MLS and BeachesMLS, free Supra lockbox access, and 11 data-sharing partnerships that expand listing exposure across markets. Members also gain access to more than 2,800 annual education programs, over 300 products and services, and a network of more than 300 global partnerships.
“From Miami-Dade to St. Lucie, a nearly 120-mile real estate corridor, we are one,” said Teresa King Kinney, the association’s co-CEO. “Every merger is about creating more opportunities for our members and together we are providing even greater access to data, technology, education and advocacy.”
Janet O’Brien, CEO of Martin County REALTORS of the Treasure Coast, said members backed the deal decisively. “Our members have spoken with overwhelming support for a future built on greater opportunity,” O’Brien said. “This merger honors the proud legacy of Martin County REALTORS of the Treasure Coast while providing our members with expanded resources, enhanced services and a stronger regional presence.”
Leadership transition ahead
The merged association is currently led by co-CEOs Kinney and Dionna Hall. Kinney plans to retire at the end of 2026, leaving Hall as sole CEO in the new year — a consolidation of leadership to match the consolidation of territory. Hall said the combination creates “greater opportunities than any one association could provide alone.” Martin County’s leadership, including president Michael Ponte, joins the combined organization, and Jonathan Dolphus serves as chair-elect.
One notable holdout remains: the town of Palm Beach, whose independent Palm Beach Board of REALTORS did not participate in the merger and continues to operate its own MLS — a small but symbolically significant island of independence in an otherwise unified Southeast Florida market. The merger still requires formal approval from NAR, with application and documentation to be submitted.
What it means
The verified facts: two mergers in two months have unified five counties of Southeast Florida under one association of roughly 94,000 members with consolidated MLS access, and NAR’s formal sign-off is pending.
The analysis: association and MLS consolidation is accelerating nationally as technology costs rise and the industry adjusts to the post-settlement commission landscape — pressures that favor scale. A five-county association with a top-three MLS gives Southeast Florida agents a single membership covering one of the nation’s most active markets, where Miami continues to lead Sun Belt home-price growth. It also concentrates influence over listing-data policy at a moment when MLS rules and private listing networks are under active debate — and, in Washington, congressional scrutiny. What to watch next: NAR’s approval timeline, and whether other large metro associations follow Southeast Florida’s playbook.
