The 4-Step Real Estate Formula That Guarantees You Never Lose Money

Most people lose money in real estate because they trust the wrong numbers. The broker's proforma, the glossy brochure, the inflated rent projections — none of it tells you the truth. Grant Cardone breaks down the exact 4-step underwriting formula he has used for over 40 years to buy deals with confidence and never lose money. This is napkin math — no complicated spreadsheets, no finance degree required. Whether you're buying your first 10-unit or your tenth 200-unit property, these fundamentals will protect your investment and sharpen your instincts every single time you look at a deal. The goal isn't just to underwrite conservatively — it's to underwrite so well that you actually pull the trigger and buy. Because you can't make money on real estate you don't own.
📌 Key Concepts Covered:
✅ How to read a T12 rent roll like a pro
✅ The actual rent formula brokers don't want you to know
✅ How to use cap rates to determine what you can pay
✅ Why independent underwriting from multiple parties protects you

  3. I see DEP25K moving right along side all the Alt’s you mentioned! Plus I see all the Alt’s plus DEP25K moving in lock step in the charts! My point is DEP25K is cheap! Retail likes buying cheap! Especially when that cheap item is on the verge of becoming expensive

  4. Great Post Thanks.. Exciting times ahead. 2026 is going to be AMAZING! The DEP25K is certainly worth the buying .Started to use my pension AVC,S .Best move ever. Thanks for all your research.

  5. Just saw your videos and bought DEP25K yesterday…..its up 24% today talk about timing……Thanks

  6. I do have a question. For someone with less than $100,000 to invest, How would you recommend we enter the market! I’m looking to study some traders and copy their strategy rather than investing myself and losing money emotionally. What’s your take on this approach??
