How do I calculate ROI on a rental property?

At a kitchen table at night, an investor uses a calculator beside a printed grid sheet, a stack of envelopes and a cup of tea
  1. Define the return measure
  2. Same period for every cost
  3. Count financing costs

The short answer

Define the return measure before calculating it. Cash-on-cash return, unlevered operating yield and total investment return answer different questions; state the period, costs and treatment of appreciation and financing.

Establish the inputs

Use documented income, vacancy, expenses, debt service, capital work and invested cash. Separate actual results from projections and avoid combining pre-tax cash with after-tax assumptions.

Test downside cases

Model lower occupancy, higher repairs and financing changes. A single attractive percentage can conceal a property that needs cash during vacancies or major replacements.

Worked example

Annual pre-tax cash flow of $6,000 on $100,000 cash invested is a 6% cash-on-cash return. It is not a complete total-return measure because it excludes items such as appreciation, sale costs and tax effects.
