What Is Rental Cash Flow?
Rental cash flow is the net income generated from a rental property after subtracting all operating expenses and mortgage payments from rental income. It helps real estate investors determine whether a property is profitable or not.

Cash flow is calculated by taking total monthly rental income and subtracting expenses such as maintenance, property taxes, insurance, and mortgage payments.
Formula Used
Net Cash Flow = Rental Income − (Expenses + Mortgage Payment)
Annual Cash Flow = Monthly Cash Flow × 12
