Aventura-area real estate agents now have a single search tool covering five counties and nearly 120 miles of Florida's Atlantic coast, after Miami Realtors completed its merger with Martin County Realtors on Friday, July 31.

The deal creates the nation's third-largest multiple listing service, connecting roughly 94,000 agents across Miami-Dade, Broward, Palm Beach, Martin and St. Lucie counties into one shared property database. Members of the combined organization sold $73.7 billion in real estate in 2025, according to The Real Deal.

For buyers shopping the Sunny Isles Beach luxury condo corridor or Golden Beach waterfront, the practical change is immediate: An agent can now pull listings from Miami Beach to Jupiter Island in a single search, rather than toggling between separate regional systems. For sellers marketing an Aventura condo, the listing now reaches a far larger pool of agents and prospective buyers across the region.

"From Miami-Dade to St. Lucie, a nearly 120-mile real estate corridor, we are one," Miami Realtors Co-CEO Teresa King Kinney said in the Miami Herald on July 31.

The July 31 merger followed an even larger consolidation in April, when Miami Realtors absorbed RWorld (formerly Broward, Palm Beaches & St. Lucie Realtors) in what the National Association of Realtors called the biggest merger in its history. Adding Martin County's century-old association completed the five-county footprint.

What changes for agents using the new MLS

The combined MLS will operate under the BeachesMLS brand. A unified IDX data feed went live approximately one week after the merger, and a task force is working to merge the two organizations' rule sets by late August, according to HousingWire.

Agents in the merged system get access to both the Flexmls and Matrix listing platforms, free Supra lockbox access and more than 2,800 education programs per year, Keys News reported.

Consumers still cannot search the MLS directly. But their agents can now view non-public data across all five counties, including showing instructions, price-change histories and internal market analytics, through one login.

How the merger fits the local luxury market

The merger arrives as Aventura-area luxury prices surge. Miami-Dade luxury single-family homes averaged $3.61 million in the second quarter of 2026, up nearly 22%, as we reported July 23. The Sunny Isles corridor saw a $21.6 million Acqualina condo flip in the first half of the year.

Dionna Hall, co-CEO of Miami Realtors + RWorld who is set to become sole CEO in 2027, told HousingWire the unified database gives competitive brokers "that full, complete picture of information" buyers and investors need.

The organization now serves nearly 7 million residents through 15 offices. The BeachesMLS rules unification is expected to wrap by late August 2026.
