Cash-on-Cash Return: The Personal Metric
While the **Cap Rate** tells you about the property's performance, **Cash-on-Cash Return** tells you about *your* performance. It measures strictly the cash coming back into your pocket relative to the cash you pulled out of your pocket to buy the asset.
Leverage: The Double-Edged Sword
If your interest rate is lower than the property's cap rate, you have "positive leverage." This will cause your Cash-on-Cash return to be *higher* than the cap rate. Conversely, if interest rates are high (above cap rates), your mortgage payments will eat so much income that your CoC return may fall below the cap rate.
Why CoC is better than ROI for Cash Flow
ROI (Return on Investment) often includes non-cash items like principal paydown and tax benefits. Cash-on-Cash is a "kitchen table" metric—it's the actual dollar amount you can spend today.
