Answer

Monthly cash flow is the amount left over after income, operating expenses, and debt payments are accounted for.

Simple version: Cash Flow = Rent − Expenses − Mortgage

More complete version: Cash Flow = (Rent + Other Income − Vacancy) − Operating Expenses − Monthly Debt Service

Example: Rent = $2,000 Vacancy = $100 Operating expenses = $600 Mortgage = $1,100 Cash flow = $200/month
