Suppose an investor purchases a $1,200,000 apartment complex with a $300,000
down payment. Each month, the cash flow from rentals, less expenses, is $5,000. Over the course of a year, the before-tax income would be $5,000 × 12 = $60,000, so the NOI (Net Operating Income)-on-cash return would be : \frac{\$\ \mbox{60,000}}{\$\ \mbox{300,000}}=0.20=20\%. However, because the investor used debt to service a portion of the asset, they are required to make debt service payments and principal repayments in this scenario (I.E. mortgage payments). Because of this, the Cash-on-Cash return would be a lower figure which would be determined by dividing the NOI after all mortgage payment expenses were deducted from it, by the total cash invested. For example: If the investor made total mortgage payments (principal+interest) of $2,000 a month in this scenario, then the Cash-on-Cash return on the investment would be as follows: • $2,000 x 12 = $24,000 • $60,000 - $24,000 = $36,000 \frac{\$\ \mbox{36,000}}{\$\ \mbox{300,000}}=0.12=12\%. ==Limitations==
