How to Calculate Rental Property Cash Flow
Cash flow is the lifeblood of rental property investing. To calculate monthly cash flow, subtract all expenses from rental income: Cash Flow = Rental Income - (Mortgage + Taxes + Insurance + Maintenance + Management + Vacancy + Reserves).
Positive cash flow means the property generates income after all expenses. Aim for at least $200-300 per door for single-family rentals, more for multi-family properties.
Understanding Cash-on-Cash Return
Cash-on-cash return measures the annual return on your actual cash invested. It's calculated as: Annual Cash Flow ÷ Total Cash Invested × 100. This metric helps compare different investment opportunities and assess whether a property meets your return requirements.
A good cash-on-cash return varies by market but generally, investors target 8-12% or higher for buy and hold properties.
