What Is ROI in Real Estate?
Return on investment measures the profit or loss a property generates relative to the capital actually committed to it — purchase price, taxes, works and all.
What ROI means
ROI is the percentage return an investment produces, measured against the total capital invested in it.
In property, ROI can combine rental income, resale profit and any other proceeds. A calculation worth trusting also counts every euro that left your account: acquisition taxes and fees, refurbishment, furnishing, financing costs, operating expenses and the costs of selling.
Its usefulness is comparability — it turns any outcome into a percentage, so a €400,000 apartment and a €3M villa can be judged side by side. Its danger is the same thing: two ROI figures are only comparable if the assumptions and the time period behind them are identical, which in practice they rarely are.
How to calculate ROI
The standard formula compares net gain against total investment cost.
ROI = (Net gain ÷ Total investment cost) × 100 Net gain is everything the investment returned, minus everything it consumed.
Total investment cost is the purchase price plus acquisition taxes and fees, legal costs, renovation, furnishing and any further capital committed. In Spain that top layer is not small: a resale in Andalucía carries 7% transfer tax and typically 9–11% in total costs; a new build runs to roughly 12–14% with VAT and stamp duty.
A worked Marbella example
A simplified, hypothetical apartment held for three years:
Total returned: €72,000 + €625,000 = €697,000
Net gain: €697,000 − €580,000 = €117,000
ROI: (€117,000 ÷ €580,000) × 100 = 20.2% over three years — roughly 6.3% annualised.

Enter a real price, rent and holding period — and see how much of the return comes from income rather than from an assumption about growth.
Note what the headline figure hides. This is a total return across the full holding period, not a yearly one; and the sale proceeds are already net of selling costs, which is why a nominally larger resale price produced a modest gain. Where the timing of cash flows matters, IRR is the more honest instrument.
How ROI varies across Marbella and the Costa del Sol
The same percentage can describe entirely different investments. A villa in La Zagaleta, Sierra Blanca or Cascada de Camoján tends to earn its return through long-term appreciation and resale positioning; an apartment in Puerto Banús, Nueva Andalucía or on the Golden Mile more often blends appreciation with rental income across a longer letting season.
In Benahavís, La Quinta and the established golf districts, results turn on details that never appear in a headline figure: development stage, community fees, management quality, financing terms and how deep the buyer pool is when you eventually sell. Two properties can print the same ROI and carry completely different risk and liquidity.
This is why SOBE Invest models each property against its own district rather than against a coast-wide average — and why the first question we ask an investor is not the target return but the holding period.
Gross ROI vs net ROI
Gross ROI
Uses proceeds before some or all expenses. Fine as a first screen across many listings; unreliable as a basis for a decision, because it flatters exactly the properties with the highest hidden costs.
Net ROI
Deducts the real costs — transaction, financing, community fees, IBI, maintenance, management, selling. On the Costa del Sol the gap between gross and net is widest precisely in the amenity-rich communities that market best.
ROI vs rental yield vs IRR
| Metric | What it measures | Best used for |
|---|---|---|
| ROI | Total gain or loss against total cost. | Judging an overall investment outcome. |
| Rental yield | Rental income against price or acquisition cost. | Assessing income-producing potential. |
| IRR | An annualised return reflecting when cash flows occur. | Comparing deals with different holding periods. |
No single metric is sufficient. Risk, liquidity, financing terms, taxation and — above all — the reliability of the assumptions decide whether a number means anything.
How mortgage leverage changes the picture
When a purchase is part-financed, investors usually measure the return on their own cash rather than on the full property value — cash-on-cash return.
Leverage amplifies in both directions. It lifts the percentage return on your capital when the property performs and the loan rate sits below the asset's yield; it magnifies losses just as efficiently, and adds interest cost, refinancing risk and a repayment obligation that does not pause for a soft market. Spanish banks lend up to 80% to residents and 60–70% to non-residents — the equity you must bring is the first constraint on any leveraged plan.
Five ways an ROI figure lies
- Purchase taxes, legal fees, renovation and furnishing quietly left out of the denominator.
- Gross rental income used where income after operating expenses belongs.
- A one-year ROI set beside a five-year ROI as though time were free.
- Projected appreciation presented as though it had already happened.
- A leveraged return compared with an unleveraged one, with the method left unstated.
Every one of these makes a property look better than it is — which is why the method deserves as much scrutiny as the number.
Frequently asked questions
What is a good ROI in real estate?
There is no universal target. An acceptable return depends on the property's risk, location, financing, holding period, liquidity and what else the investor could do with the same capital. A 6% return on a liquid prime asset can beat 9% on an illiquid one.
Is ROI the same as rental yield?
No. Rental yield looks only at rental income against price; ROI includes both income and capital gain or loss over the whole holding period.
Is ROI the same as IRR?
No. ROI gives a total percentage result. IRR accounts for when each cash flow occurs and expresses the outcome as an annualised rate — the fairer comparison across different holding periods.
Should taxes and fees be included?
Yes, for any calculation meant to inform a decision. In Spain, acquisition costs of 9–14% and selling costs are large enough that excluding them changes the answer, not just the decimal.
Can ROI be negative?
Yes — whenever total money returned falls short of total money invested. Short holding periods in Spain are the common cause: transaction costs alone can consume the first years of appreciation.
