Comparison for Florida listing agents
Market Leader vs Sourtio: predictive data or verified seller leads?
Market Leader is one of the best known seller lead products in real estate. It sells predictive data: an algorithm ranking which households in your farm may list in the next 6 to 18 months, usually on a 12-month agreement. Sourtio does something different. The Exclusive Listing Engine delivers Florida homeowners who requested a valuation this week, phone-verified, 100% exclusive to one agent, with no contract.
Side-by-side comparison
| What matters | Market Leader | Sourtio |
|---|---|---|
| Lead type | Predictive data: algorithms guessing who might sell in 6-18 months | Homeowners who requested a valuation this week, in their own words |
| Exclusivity | Leads commonly shared with several agents in the same area | 100% exclusive: one lead, one agent, never resold |
| Verification | Delivered as-is; dead numbers and renters are your problem | Phone-verified and owner-confirmed before delivery |
| Bad lead policy | Credits vary by plan and dispute process | Verified-or-free: it fails our criteria, you don't pay for it |
| Contract | Typically 12 months with early termination fees | No contract, no auto-renewal. Buy a block, reorder if it works |
| Speed | Batch lists and nurture campaigns | Real-time push, so you call inside the 5-minute window |
| Coverage | Nationwide | Florida only, one agent per county while a county stays open |
Verification: verified-or-free vs as-is
The single biggest cost in any seller lead program is not the lead price, it is the hours you burn on numbers that never connect. Predictive lists are scored, not verified: nobody picks up the phone before it reaches you.
Every Sourtio lead clears five mandatory checks before delivery: the homeowner requested a valuation on their own property this week, answered timeframe and motivation questions in their own words, had their phone number verified, was confirmed as the property owner, and is delivered to you alone. Fail one, and it never reaches you. If a delivered lead fails anyway, it is credited back, no dispute process.
Exclusivity: one lead, one agent
MIT's lead-response research found the same inquiry is commonly worked by 4 to 7 agents, and that calling within 5 minutes instead of 30 makes you 21x more likely to qualify the lead. NAR reports 78% of sellers list with the first agent who responds. Shared leads turn that into a race you often lose before you dial.
Sourtio never resells a lead. That is also the constraint: each Florida county only supports a limited number of agents before it closes.
When Market Leader is the better fit
If you farm a neighborhood for years, mail consistently, and want a nationwide CRM with predictive scoring baked in, a predictive product can fit. If you want the phone to ring with someone who asked about their home value this week, in Florida, exclusively, that is what the Engine does.
Frequently asked questions
Is Market Leader the same company as SmartZip and Offrs?
Market Leader, SmartZip, and Offrs sit under the same parent group, Constellation Real Estate Group. Different logos, broadly the same predictive-data product.
What is wrong with predictive seller data?
Nothing, if you have time. A predictive score says a household may sell within 6 to 18 months. It is a farming tool, not a listing appointment. Sourtio only delivers homeowners who already raised their hand and asked what their property is worth.
Are Market Leader leads exclusive?
Exclusivity depends on the product and the ZIP you buy. Shared distribution is common across the big providers, and MIT's lead-response research shows the same inquiry often reaches 4 to 7 agents. Every Sourtio lead goes to exactly one agent.
What does Sourtio cost compared to Market Leader?
Sourtio is priced per lead and depends on your county and volume, with no contract and no early termination fee. You get plain numbers on a two-minute qualifying call.
