Sphere of Influence: The Highest Net Margin Leads.
Many agents mistake high transaction counts for financial success. But buying leads from paid portals (like Zillow or Realtor.com) can eat up 35% of your commission in referral fees. Your organic Sphere of Influence (SOI) yields the highest margins in real estate. Let's compare the metrics.

The Cost of Portal Leads vs. Sphere Leads
When evaluating lead generation models, real estate agents must separate gross commission from net margins. Here is how paid lead portals compare to your database:
- Paid Portals (Zillow/Realtor.com): Often charge a 30% to 35% broker-to-broker referral fee at closing on successfully closed deals, or demand high monthly upfront subscription fees with low conversion rates (1% to 3%).
- Your Sphere of Influence (SOI): Costs almost nothing to source. A client appreciation event, coffee chats, and regular email newsletters are the only expenses. The referral fee is **0%**.
Why Tracking Lead Sources in Your Ledger Matters
By tagging every transaction in your ledger with its `leadSource` (e.g. *Sphere*, *Zillow*, *Open House*, *Cold Calling*), you can see exactly which marketing channels yield the highest margins.
Closing 5 deals from your sphere can net you **more take-home cash** than closing 8 deals from a paid portal once you subtract paid referral splits and ad spend.
