Miami Realtors adds Martin County, reaching 94,000 members
Two mergers in ten weeks have turned the listing map from Miami-Dade to St. Lucie into one search.
MIAMI REALTORS + RWorld has merged with Martin County REALTORS of the Treasure Coast, bringing the association to roughly 94,000 members across Miami-Dade, Broward, Palm Beach, Martin and St. Lucie counties. It is the group’s second merger in a little over two months, following the May 11 combination that was the largest in National Association of Realtors history.
Why it matters
For agents, this is a data question dressed up as an association announcement. A single MLS now covers a 120-mile corridor, which means a Miami-Dade agent can search Stuart inventory natively and a Treasure Coast agent gets exposure to South Florida buyer traffic without a reciprocal agreement. Cross-county referral friction is where a lot of Florida commission dollars quietly leak, and consolidating the listing pool removes a chunk of it.
For developers and builders, the practical effect is comp coverage. Treasure Coast pricing has been the least legible part of the Southeast Florida market because it sat in a separate feed. Sales velocity and price-per-foot data from Martin and St. Lucie now sit alongside Palm Beach in the same system, which matters if you are underwriting the migration of priced-out buyers north.
The numbers
The merged association counts approximately 94,000 members across five counties and now ranks as the nation’s third-largest MLS. The Martin County merger completes the unification of the Treasure Coast within the organization. The prior RWorld merger closed May 11, 2026.
What’s next
Watch whether the association pushes further north into Indian River and Brevard, and watch how a unified five-county feed changes reported inventory. When two separate MLS systems become one, apparent supply in the combined market can jump without a single new listing hitting the street, and that is a number worth reading carefully this fall. More South Florida coverage.
