What cash on cash return measures

Cash on cash return is the yearly pre-tax cash flow a rental puts in your pocket divided by the cash you actually put in. It's the return on your money after the mortgage, which is why investors using leverage watch it more closely than the cap rate.

Cash on cash return = (NOI − annual debt service) ÷ (down payment + closing costs + upfront repairs)

Worked example

A $300,000 rental bought with 25% down, $9,000 of closing costs and $6,000 of repairs ties up $90,000. At $2,600 rent with 5% vacancy and $900 a month of costs, NOI is $18,840. A $225,000 loan at 7% for 30 years costs $17,963 a year, leaving $877 of cash flow: a cash on cash return of 0.97%. The cap rate on the same deal is 6.28%; when the mortgage rate is above the cap rate, leverage lowers your cash return.

After tax

Rental income is taxed after deducting mortgage interest, operating costs and depreciation of the building over 27.5 years (IRS Publication 527), so many rentals with positive cash flow show little taxable income. Run the rental property depreciation calculator for the deduction, and check lender limits with the DSCR loan calculator.
