What is Real Estate ROI?
Real estate ROI is the percentage return on cash you invest (usually equity at purchase) versus total profit from operations, loan paydown, and change in value at exit. It connects income, leverage, and appreciation in one decision frame.
Key metrics
- ROI — Total return on cash invested over your hold, including sale; use the rental calculator for a financed buy-and-hold path.
- Cap rate — NOI ÷ price, unlevered; best for comparing properties before financing.
- Cash-on-cash return — Annual pre-tax cash flow ÷ cash invested; best for year-one yield on equity.
- Flip ROI — Profit ÷ all-in cost for a short-cycle rehab and sale.
| Metric | Best For | Limitation |
|---|---|---|
| ROI | Total return over time | Ignores time value |
| Cap Rate | Quick property comparison | Ignores financing |
| Cash-on-Cash | Leveraged investments | Short-term focused |
When to use each metric
- Use cap rate to rank deals on an apples-to-apples yield before debt.
- Use cash-on-cash when you care about cash income on equity this year.
- Use total ROI when you want the full story through exit (rent, paydown, appreciation).
- Use flip ROI when the strategy is buy → renovate → sell, not long-term rent.
Common investor mistakes
- Ignoring vacancy and capex — underwriting gross rent without haircuts.
- Mixing cap rate with levered ROI — compare cap to cap, levered to levered.
- Overstating appreciation — stress-test 0% to see income-only viability.
- Ignoring closing and sale costs — this site’s rental model does not add them; adjust manually.
