Many Spanish property buyers plan to rent when they're not using it. The rental income helps offset carrying costs, and a well-located Costa del Sol property can generate €25,000-€40,000 annually in holiday lets. But between intention and income lies a maze of regulations, practicalities, and decisions. Here's how to navigate it.
The License Question
Spain regulates short-term rentals through the autonomous communities, with further rules at municipal level. The Costa del Sol falls under Andalucía's regulations, which require a property to be registered and licensed for tourist rental (vivienda turística).
Requirements for Andalucía registration:
- The property must meet basic habitability standards (hot water, heating/cooling, equipped kitchen)
- Bedrooms must have adequate natural light and ventilation
- First-aid kit and emergency information required
- Declaration to the Junta de Andalucía tourist registry
The process is relatively straightforward—submit an application (responsable declaration) and, assuming your property meets requirements, you receive a registration number within days. You must display this number in all advertising.
The complications:
- Some communities (comunidades de propietarios) prohibit or restrict holiday rentals. Check your community's rules before purchasing if rental is important.
- Municipalities can impose additional restrictions. Marbella has discussed limiting licenses in certain areas. Regulations evolve.
- Unregistered rental is illegal and can result in fines of €2,000-€18,000 or more for repeat offences.
Understanding Realistic Returns
Holiday rental income depends enormously on location, property quality, and management approach.
Prime locations (beachfront Marbella, Puerto Banús, central Málaga):
- Peak summer: €200-€400/night for a quality 2-bedroom
- Shoulder season: €120-€200/night
- Winter: €80-€120/night (occupancy drops)
- Annual potential: €30,000-€45,000 gross at 65-75% occupancy
Good but not prime locations:
- Peak summer: €120-€200/night
- Shoulder season: €80-€120/night
- Winter: €50-€80/night
- Annual potential: €18,000-€28,000 gross at 55-65% occupancy
Costs to subtract:
- Management (if used): 15-25% of gross rental
- Cleaning between guests: €50-€100 per turnover
- Utilities (higher with frequent turnovers): €200-€400/month in season
- Platform fees (Airbnb, Booking.com): 3-15% depending on structure
- Maintenance and wear: budget 10% of gross
- Insurance (higher for rentals): €400-€800/year
- Taxes (see below)
Net returns typically run 50-60% of gross rental income after all costs.

Managing Your Rental
Three approaches, each with trade-offs:
Self-management:
- Highest returns (no management fee)
- Requires constant availability for guest communication
- Need local contacts for cleaning, maintenance, emergencies
- Practical only if you're nearby or have excellent systems
Local property management company:
- Typically 15-25% of gross rental
- Handle everything: listings, bookings, cleaning, guest support, maintenance
- Quality varies enormously—get references
- Some charge extra for check-ins, laundry, etc.—clarify fee structure
Hybrid approach:
- Handle listings and bookings yourself (Airbnb, Booking.com, direct)
- Use local services for cleaning and key exchange
- Have a maintenance contact for emergencies
- Works if you're organised and available for communication
Tax Obligations
Spanish rental income is taxable, with significant differences based on residency status.
For non-residents (most UK owners):
- Tax rate: 24% on gross rental income (no expense deductions for non-EU)
- For EU citizens: 19% on net income (expenses deductible)
- Must file quarterly declarations (Form 210) for each rental period
- Tax also due on "deemed income" for periods of personal use
Example: €25,000 gross rental, UK non-resident = €6,000 Spanish tax due
For Spanish residents:
- Rental income joins general taxable income (19-47% marginal rates)
- Expenses fully deductible: mortgage interest, insurance, repairs, management fees, community fees, IBI, depreciation
- Long-term rental (not holiday lets) qualifies for 50-90% income reduction depending on circumstances
The tax difference between resident and non-resident status can be substantial. If you're generating significant rental income and spending considerable time in Spain, residency may make financial sense.
Making Your Property Rental-Ready
Properties that rent well share common features:
- Air conditioning: Essential, not optional. Spanish summers are hot.
- WiFi: Fast and reliable. Guests expect it.
- Outdoor space: A terrace or garden dramatically improves appeal.
- Pool access: Shared or private, pools drive summer bookings.
- Modern kitchen: Doesn't need to be huge but should be equipped and clean.
- Quality beds: Comfortable mattresses get mentioned in reviews. Poor ones do too.
- Professional photos: The difference in booking rates is significant.
- Thoughtful extras: Welcome pack, local recommendations, beach equipment.
Platform Strategy
Most owners list on multiple platforms:
- Airbnb: Largest market share for holiday rentals. 3% host fee (more if guests pay no service fee). Strong in UK/US markets.
- Booking.com: Stronger in European markets, particularly German and Dutch. 15% commission but often delivers bookings Airbnb doesn't.
- VRBO/HomeAway: Stronger for family groups and longer stays. Owned by Expedia.
- Direct bookings: No fees, but requires your own marketing. Worth developing for repeat guests.
Calendar synchronisation across platforms prevents double bookings—most property management software handles this automatically.

The Bigger Picture
Rental income is appealing, but enter with realistic expectations. After all costs and taxes, net returns of 3-5% on property value are typical—attractive compared to some investments, but not transformative wealth.
More importantly, rental changes how you use your property. Peak season (when rental income is highest) is also when you might most want to visit. Managing bookings, guest communications, and maintenance issues takes time and attention. Some owners find the income worth these trade-offs; others decide they'd rather enjoy their property without the hassle.
Consider your priorities honestly. If the numbers only work with maximum rental occupancy, you might not own a holiday home—you might own a small hospitality business. That's fine if it's what you want, but know what you're choosing.
