For commercial real estate, the “MLS” concept is a bit different—most platforms are data exchanges + marketing marketplaces rather than cooperative MLS systems like residential. That said, these are the top 3 dominant platforms used nationwide (including Florida):
What it is:
The industry’s most comprehensive commercial property database and analytics platform.
Why it dominates:
Massive proprietary database (researched, not just agent-submitted)
Deep comps, lease data, ownership records, tenant info
Strong for investment analysis and underwriting
Best use case:
Brokers doing serious deal analysis, BOVs, and institutional-level work
Downside:
Expensive (typically $500–$1,500+/month depending on package)
Not truly cooperative like an MLS
What it is:
The largest public-facing commercial listing marketplace (owned by CoStar).
Why it matters:
Massive exposure to investors and buyers
Most brokers syndicate listings here
Acts as the “Zillow of commercial real estate”
Best use case:
Marketing listings to buyers
Generating inbound leads
Downside:
Limited data depth compared to CoStar
Pay-to-play for premium exposure
What it is:
A fast-growing commercial listing + deal management platform
Why it’s gaining traction:
More modern UI than LoopNet
Built-in marketing tools, email blasts, deal rooms
Supports auction-style listings and offer management
Best use case:
Brokers who want marketing + CRM-style tools in one place
Syndication + lead tracking
Downside:
Data is not as deep as CoStar
Still building market dominance in some regions
| Platform | Primary Function | Strength |
|---|---|---|
| CoStar | Data + analytics | Best for comps, ownership, underwriting |
| LoopNet | Marketplace | Best for exposure to buyers |
| Crexi | Marketplace + tools | Best for marketing + workflow |
In Tampa / Manatee / Sarasota:
CoStar = must-have if you're doing serious commercial deals
LoopNet = baseline exposure (almost required for listings)
Crexi = growing fast, especially with smaller investors and syndicators
If you're looking for something closer to a true MLS cooperation model, you may also encounter:
Catylist (used by CCIM chapters/associations)
CCIM Institute networks
These are more “MLS-like” but far less dominant than the big three above.
