The Costa del Sol has long been one of Europe’s favourite places to own a second home, and increasingly a place to invest for rental income.
If you’re weighing up buy-to-let on the Costa del Sol, the fundamentals are attractive — strong tourism, a long season and steady demand — but the returns depend on buying the right property, in the right area, and running it well.
This guide walks through how buy-to-let works here, the costs, the taxes, the rules and how to make the numbers stack up.
The appeal rests on a few durable strengths.
The Costa del Sol enjoys one of the longest tourist seasons in Europe, helped by mild winters, golf, events and a growing digital-nomad and remote-work crowd that extends demand beyond summer.
Málaga airport offers excellent connectivity to northern Europe, feeding a constant stream of guests.
Property prices, while rising, remain accessible compared with many European coastal markets, and short-term rental yields in prime towns are healthy.
For an investor seeking a blend of rental income, lifestyle and long-term capital appreciation, few European destinations combine all three as well.
Your first strategic decision is the rental model. Short-term (holiday) letting usually generates higher gross income in high-demand coastal towns, but carries more cost, effort, regulation and a different tax treatment. Long-term letting is simpler and steadier but lower-yielding in prime areas.
Many buy-to-let investors on the coast favour short-term letting precisely because the tourism demand is what makes the numbers work — but the right answer depends on the property, the area’s rules and how hands-on you want to be.
Model both before you commit.
Location drives returns.
Marbella and the Golden Mile command premium rates but high entry prices; Estepona offers quality with more upside; Fuengirola, Benalmadena and Torremolinos deliver dependable, year-round occupancy at accessible prices; Mijas and La Cala draw golf and family demand; and Málaga city wins on year-round, city-break resilience.
The best area for buy-to-let depends on your budget and target yield rather than prestige.
As a rule, the mid-priced, high-demand towns often produce the strongest rental yields, while Marbella leads on capital value and nightly rate.
Budget for more than the asking price.
On a resale property you’ll typically pay transfer tax (ITP) — in Andalusia around 7% — plus notary, land registry and legal fees, usually adding up to roughly 10–12% of the purchase price in total.
New-build purchases carry VAT (IVA) plus stamp duty instead of ITP. Then factor in furnishing, any renovation, and setup costs to make the property rentable.
A realistic buy-to-let calculation starts from this all-in figure, not the headline price, because those costs are real money you’ve invested.
Non-residents can get Spanish mortgages, but typically on tighter terms than residents — often financing up to around 60–70% of the property’s value, meaning a larger deposit.
Rates, conditions and the paperwork vary by bank, and lenders assess your income and existing commitments.
Mortgage interest is a deductible cost for EU-resident landlords but not for non-EU owners such as UK investors post-Brexit, which affects the after-tax maths.
If you’re financing the purchase, factor the repayments into your yield calculation and stress-test them against the quieter months, not just peak season.
Rental income from a Spanish property is taxed in Spain.
Non-residents pay non-resident income tax on form Modelo 210 — 19% on net income for EU/EEA residents (with deductible expenses) and 24% on gross for non-EU residents, including UK owners since Brexit, with no deductions.
You’ll also pay annual property tax (IBI) and, as a non-resident, a small imputed-income tax for periods the property isn’t let. Tax materially affects net yield, so build it into the model from the start.
We cover it in our guide to non-resident rental tax in Spain.
To let short-term legally you must register the property as a tourist rental (a VFT in Andalusia) and obtain the national NRUA number, meet the property requirements, and report guests to the authorities.
Crucially, your building’s community of owners can restrict or block tourist letting, so this must be checked before you buy with rental income in mind.
A property that can’t be legally let short-term is a very different investment. See our guides to the tourist licence in Andalucia and the rules before committing.
To estimate returns, project realistic annual income — average nightly rate times expected occupancy — then subtract all running costs and tax, and divide by your total investment.
Be conservative: use achievable occupancy (often 65–85% for well-managed coastal properties, lower in weaker spots) and include every cost. The net yield, not the gross, is what tells you whether a property is a good buy-to-let.
A slightly lower-priced apartment with strong, steady demand frequently out-yields a prestigious but expensive one, so let the numbers, not the postcode, lead.
Beyond the purchase, ongoing costs shape your yield: management commission (if you use a company), cleaning and linen, utilities, community fees, IBI, insurance, maintenance, platform fees and consumables.
Together these commonly absorb 30–45% of gross income before tax. New investors routinely underestimate them and are then disappointed by the net figure.
Listing every cost honestly — and revisiting it annually — is what separates a buy-to-let that performs to plan from one that quietly disappoints.
The frequent missteps: buying on lifestyle appeal rather than rental numbers; ignoring the community’s stance on tourist letting; underestimating costs and tax; over-optimistic occupancy assumptions; choosing the wrong area for short-term demand; and planning to self-manage from abroad without realising the workload.
Each is avoidable with due diligence. The investors who do well treat a buy-to-let as a business decision backed by realistic figures, not an emotional purchase justified by a sea view.
Numbers make it concrete. Say you buy a two-bed apartment in Fuengirola for €230,000, plus around €25,000 in purchase costs, furnishing and setup — a total investment of €255,000.
Well managed as a short-term let, it grosses roughly €30,000 a year at €120 a night and 70% occupancy.
After running costs of around €13,000 (management, cleaning, utilities, community, IBI, insurance, maintenance), the net is about €17,000 before tax.
That’s a net yield of roughly 6.7% on your investment before tax — and before any capital appreciation.
Drop occupancy or buy in a weaker location and that figure falls, which is exactly why the area, the price you pay and the quality of management all matter so much to the final return.
Both routes work for buy-to-let, with trade-offs. Resale properties are often in established, central locations close to the beach and amenities — prime rental territory — and carry transfer tax rather than VAT. New-builds offer modern finishes, lower maintenance and features guests love (pools, gyms), but carry VAT plus stamp duty, may sit slightly further from the seafront, and can take time to complete.
For pure rental yield, a well-located resale near the beach often performs strongly; for a lower-maintenance, turnkey asset, a new-build can appeal. Weigh location against condition for your strategy.
For most overseas buy-to-let investors, professional management isn’t a luxury — it’s what makes the model viable.
A local company handles pricing, listings, guests, cleaning, maintenance, compliance and the guest reporting, turning a property hundreds of miles away into a genuinely passive income stream.
It also protects your yield: better pricing and occupancy typically more than cover the fee.
Before you buy, talking to a manager who works across the province can also give you a realistic income projection for the specific property you’re considering — invaluable due diligence.
For a well-chosen, well-run property, buy-to-let on the Costa del Sol remains one of the more attractive ways to combine rental income with lifestyle and long-term capital growth in Europe.
But it rewards diligence: the right area, honest numbers, full legal compliance and good management.
Go in with realistic projections, budget for all the costs and tax, confirm you can legally let the property short-term, and the coast can deliver a solid return.

For a well-located, well-managed property it can be, combining rental income, lifestyle and capital growth. Returns depend on buying in the right area, running realistic numbers, full legal compliance and good management.
On a resale, expect transfer tax (around 7% in Andalusia) plus notary, registry and legal fees — roughly 10–12% of the price in total — plus furnishing and any renovation. New-builds carry VAT and stamp duty instead.
Yes, though typically financing up to around 60–70% of value, requiring a larger deposit, with terms varying by bank. Factor the repayments into your yield and stress-test the quieter months.
