Cap Rate vs Cash-on-Cash: Which One Actually Matters

Calculator screenshot

The difference between a 5% cap rate and a 7% cap rate on a $200K property is $4,000 per year in NOI. That is $333/month. Real money.

But here is what nobody tells you about comparing: cap rate alone does not tell you if the deal works. A 7% cap rate with 9% vacancy and rising insurance can produce negative cash flow. A 5% cap rate in a tight market with 4% vacancy might actually cash flow better after financing.

The numbers I check on every deal:

  1. Cap rate — is the property earning enough relative to price?
  2. Cash flow — can I cover the mortgage and still eat?
  3. DSCR — will a lender actually fund this?
  4. Total ROI — what do I make over 5-10 years including equity?

Four numbers. Two minutes each. That is the entire analysis.
