Where Deals Are Won or Lost

The meaty one. The math other people sell a $2,000 course on — taught here for nothing.

Deals are usually killed by tiny assumptions wearing nice clothes.

Optional progress lives on this browser. No account, no gate.

Who this is for

Investors who want to check the math sponsors hope nobody checks.

What it fixes

You stop nodding at projections and start interrogating them.

How to read it

Move from rent roll to NOI to cap rate to stress test. No romance. Just the math.

Assumption breaker

Find the number that makes the deal fall over.

The model is not a truth machine. It is a map of assumptions. Your job is to find which assumption is carrying too much weight.

  1. Trace rent to the rent roll
  2. Rebuild NOI
  3. Stress debt service
  4. Move the exit cap
Break the model

Find the assumption that breaks first.

Use these first when the spreadsheet looks like a priest wrote it.
