Most novice investors evaluate rentals by intuition — 'the rent looks high enough to cover the mortgage.' That mental shortcut ignores roughly half of a property's true cost structure.
Real ROI analysis is a disciplined seven-step process: model the financing, project gross rent, deduct vacancy, deduct operating expenses (taxes, insurance, maintenance, management, capex reserves), compute NOI, deduct debt service to get cash flow, and finally express the result as both cash-on-cash and total annual return.
Skipping any step produces a deal that looks better on paper than it performs in reality. Use our rental ROI calculator to enforce the full seven-step framework on every deal you screen.
