Formulas, assumptions, and limits
- Vacancy allowance is gross monthly rent multiplied by the entered vacancy rate. Enter the rate as a percent from 0 to 100; no vacancy rate is assumed.
- Operating expenses are entered as one monthly total and should include recurring property operating costs such as taxes, insurance, maintenance, management, utilities, or HOA as applicable. They exclude debt service and vacancy allowance.
- NOI excludes debt service, income taxes, initial reserves, and one-time rehabilitation costs. Debt service is subtracted only for monthly pre-tax cash flow.
- Estimated cash required and the cash-on-cash denominator include only the entered down payment, purchase closing costs, rehabilitation costs, and initial reserves.
- Annual figures multiply one entered monthly estimate by 12; this is a simple annualization and does not model changing rents, costs, timing, financing, or taxes.
- Missing or invalid inputs are shown for each affected result. A zero denominator prevents a percentage from being calculated. Results do not verify documents, property condition, rent, expenses, financing, or local requirements.
