The Origin Story of the
Underworld Deal System™ Negotiator
Every mafia documentary has the scene where the boss stops playing by the world’s rules
and builds his own system.
This is that moment — for real estate deals.
The Problem That Started It All
Every empire rises after one moment of betrayal… in real estate, that betrayal is bad information. Deals collapsing because the math was wrong.
- ARVs pulled from fantasy.
- Repair costs guessed.
- Offers made blind.
The Don watched the chaos for years — and decided enough was enough.
Deals weren’t dying because they were bad — they were dying because the *numbers* were bad.

Who Built It
The Underworld Deal System™ Negotiator was created by CJJV Real Estate Investing, LLC, founded by Clyde N. Cook III — the industry knows him as The Real Estate Don®.
A strategist. A negotiator. A builder of systems that protect the downside and expose the truth. After analyzing hundreds of deals and mentoring new investors, he realized the market was flooded with weak calculators pretending to be underwriting tools.
So he built something better — a true decision engine that thinks like a wholesaler, a flipper, a creative finance expert, a landlord, and a closer.
