Gross income = rent + other income. Effective income = gross × (1 − vacancy). NOI = effective income − operating expenses; mortgage payments are not part of NOI. Cash flow = NOI − mortgage payment. Cash invested = down payment + closing costs + repairs. Cash-on-cash = annual cash flow ÷ cash invested. Gross yield = annual gross income ÷ price. Break-even occupancy = (operating expenses + mortgage) ÷ gross income; above 100% means the property would not cover costs even when fully rented. Mortgage payments come from a standard amortization formula and may differ from your lender’s quote. Property taxes, income tax, capital costs and appreciation are not modelled. Verify financing, insurance, tax and legal obligations with qualified professionals.
