World’s largest local Realtor association expands, building on South Florida’s incredible momentum

by Teresa King Kinney and Dionna Hall

It’s Miami and South Florida’s time, and it’s only just beginning.  

New York, Chicago, Los Angeles. They’re all much older U.S. cities that had their time in the sun. Miami, incorporated 243 years after New York, is now just stepping into the batter’s box in the early innings of a golden era.  

Just how hot is Miami and South Florida real estate? Two of the world’s richest men with South Florida headquarters, Citadel CEO Ken Griffin and Related Ross CEO Stephen Ross, are investing $10 million of their own money to recruit more CEOs to the region. That’s just one example of South Florida’s massive ongoing wealth transfer.  

To build on this incredible momentum, Miami and South Florida’s real estate associations have merged to bring our Realtors more data, more innovation, stronger advocacy and greater opportunities so they can launch more global business. MIAMI REALTORS® + RWorld completed two mergers in just over two months in 2026, strengthening the world’s largest local Realtor association and the nation’s third-largest Multiple Listing Service.  

MIAMI REALTORS®, the largest U.S. local Realtor association with 56,000 members at the time, and RWorld, the third largest with 37,000 members, merged in May. Then MIAMI REALTORS® + RWorld merged with Martin County REALTORS® (MCRTC) of the Treasure Coast in July.  

The mergers unified the South Florida marketplace, created the most complete South Florida MLS dataset and expanded the association to approximately 94,000 members. Meet your new association and our five-county region of Miami-Dade, Broward, Palm Beach, Martin and St. Lucie counties. MIAMI REALTORS® + RWorld now serves a region of nearly  seven million residents  throughout 14 South Florida offices. 

Building for the future 

The mergers that created MIAMI REALTORS® + RWorld are about building the strongest possible organization for our members and our future.  

An outstanding organization is critical for our member’s success — we are committed to remaining at the forefront of a rapidly evolving real estate industry to ensure that both our association and our MLSs are best able to serve our members, their businesses and, in turn, their clients. 

MIAMI + RWorld + MCRTC members now benefit from: 

  • The most complete South Florida MLS dataset 
  • The nation’s third-largest MLS 
  • Access to both Flexmls and Matrix platforms 
  • Free IDX feeds from both MIAMI MLS and BeachesMLS 
  • More than 2,800 education programs annually 
  • More than 300 products and services 
  • More than 300 global partnerships 
  • Free Supra access for all Realtors 
  • More than 11 data-sharing partnerships to expand listing exposure 
  • The collective advocacy of about 94,000 Realtors protecting homeownership and private property rights 

Business doesn’t stop at the county line 

Our 94,000 Realtors do business for their clients throughout our five-county and 120-mile real estate corridor. They don’t stop because a buyer is in a different county. They make the deal happen. 

By merging our three associations together we are creating a world-class organization that will deliver more data, more innovation, stronger advocacy and greater opportunities to our members than any one association could provide alone. 

By merging we are finally providing our members a complete dataset to power their products and services. No more fragmented data stalling deals. By merging, we are in the process of creating one set of MLS rules and regulations in South Florida. No more confusion or doubt. 

This is all about our members. Let’s give them the world’s best resources and services so they can be more profitable and successful in the global marketplace.  

Uniting together unlocks a new era of unlimited possibilities and global business for our members, their clients, our communities and our market.  

South Florida real estate: The global powerhouse

Ken Griffin knows it. Stephen Ross knows. The world knows it. 

The world is in love with South Florida. It’s not just because of our weather. South Florida is where global business happens. Where global CEOs scale their business. Where companies connect and expand with our neighbor and partner, Latin America, and the world.  

South Florida is pro-business, pro-development and pro-wealth accumulation. South Florida is a perennial leader in home price appreciation. We are a top FinTech hub. We are the No. 1 U.S. destination for global home buyers. South Florida leads in its continued influx of billionaires, executives and new businesses. 

Global wealth, business migration, lifestyle migration and the most in-demand prime land in the U.S. have all met at the right time and the right place: Miami and South Florida.  

For 106 years, MIAMI REALTORS® + RWorld has provided world-class resources and services to our members and protected property rights. Now, we have expanded into the world’s largest local Realtor association, but the mission is the same.  

We will continue providing our members with the most data, tools and education so they serve their clients at the highest level. Let’s keep building South Florida into the best place in the world to live, work and invest. 

Teresa King Kinney and Dionna Hall are co-CEOs of MIAMI REALTORS® + RWorld
