Rental yield is the single most important metric for any buy-to-let investor. Before you commit to purchasing a property in Spain, you need to know not just the purchase price, but what return that capital will generate year after year. This guide breaks down how to calculate gross and net yield, what numbers to realistically expect across Spain’s major cities, and how to build a proper investment analysis.
What Is Rental Yield?
Rental yield expresses your annual rental income as a percentage of the property’s purchase price. It is the most direct measure of how efficiently your capital is being deployed in a property investment.
There are two key variants:
- Gross rental yield — a quick headline figure, before costs
- Net rental yield — the figure that actually matters, after all expenses
Gross Rental Yield: The Formula
Gross Yield (%) = (Annual Rental Income ÷ Property Purchase Price) × 100
Example
- Property price: €180,000
- Monthly rent: €900
- Annual rental income: €10,800
- Gross yield: 10,800 ÷ 180,000 × 100 = 6.0%
Gross yield is useful for quick comparisons between properties, but it is never the number you should base an investment decision on.
Net Rental Yield: What You Actually Earn
Net Yield (%) = ((Annual Rental Income − Annual Expenses) ÷ Total Investment) × 100
Your total investment should include the purchase price plus all acquisition costs (ITP or IVA, notary, registry, agency fees — typically 10–13% on top of the price).
Annual expenses to deduct:
- Community fees (comunidad de propietarios) — typically €600–€1,800/year
- IBI (local property tax) — typically €200–€800/year depending on Catastro value
- Home insurance — typically €200–€400/year
- Property management fee (if using an agent) — typically 8–12% of annual rent
- Maintenance and repairs — budget approximately 1% of property value per year
- Vacancy allowance — assume 1–2 months’ vacancy per year
- Income tax on rental income (IRPF for residents, IRNR for non-residents) — 19–24% on net income
Example Net Yield Calculation
- Purchase price: €180,000 + €20,000 acquisition costs = €200,000 total investment
- Annual rent: €10,800
- Annual expenses: €3,200 (management, IBI, community, insurance, maintenance)
- Net income: €7,600
- Net yield: 7,600 ÷ 200,000 × 100 = 3.8%
A significant drop from the 6% gross figure — and this is before income tax.
Rental Yields by City in Spain (2026)
Spain’s rental market varies dramatically by location. Here is a realistic picture of achievable gross yields in major cities:
| City | Typical Gross Yield | Notes |
|---|---|---|
| Murcia | 6.5–8%+ | Highest yields nationally; strong student demand |
| Valencia | 5–6.5% | Strong demand, rising prices still favourable |
| Alicante | 5–7% | Mix of long-let and seasonal; good gross yields |
| Seville | 5–6% | Growing demand; lower prices than coastal areas |
| Zaragoza | 5–6.5% | Underrated market with solid fundamentals |
| Bilbao | 4.5–5.5% | Stable, professional tenant base |
| Barcelona | 4–5% | High prices suppress yields; regulatory risk |
| Madrid | 3.5–5% | Strong demand but high purchase prices |
| Marbella/Costa del Sol | 3–5% | Premium prices; seasonal tourism model |
| Palma de Mallorca | 3–4.5% | Very high prices; seasonal dependency |
Key insight: The highest-yielding markets (Murcia, interior cities) often offer better rental returns but lower capital appreciation prospects. Madrid and Barcelona offer lower yields but stronger long-term price growth historically.
What Is a “Good” Rental Yield in Spain?
As a general benchmark:
- Below 4% net — difficult to justify vs other investments; margin for error is slim
- 4–5% net — acceptable for prime locations with strong appreciation potential
- 5–7% net — strong return; solid buy-to-let investment case
- Above 7% net — exceptional, but verify quality of location and tenant demand
Always underwrite conservatively: use a 10-month occupancy assumption (not 12) and include a proper maintenance reserve.
Key Factors That Affect Your Net Yield
Property type matters. Smaller apartments (one and two-bedroom) typically yield better than large family homes or luxury villas, which are harder to keep occupied year-round.
Furnished vs unfurnished. Furnished properties command higher monthly rents but incur higher maintenance costs. Long-let unfurnished is generally lower-risk.
Short-term vs long-term rental. Tourist licences (licencias turísticas) are increasingly restricted in major Spanish cities. Airbnb-style yields can be attractive, but regulatory risk is substantial. Always verify local regulations before banking on short-term rental income.
Leverage. If you use a Spanish mortgage (typically available to non-residents at 60–70% LTV), your cash-on-cash return will differ materially from the yield on total asset value. Model both.
Building Your Investment Analysis
A professional approach combines:
- Net yield on total investment (including acquisition costs)
- Cash-on-cash return if leveraged
- 5 and 10-year IRR assuming conservative capital growth (2–3% per annum)
- Stress test — what happens if rent falls 15% or vacancy doubles?
Run the Numbers on Your Investment
Before committing to any buy-to-let purchase in Spain, you need to know your exact acquisition costs — ITP or IVA, notary, registry, and agent fees — because they directly affect your net yield.
