Purchasing a new-build property in the premium segment of the Costa del Sol as an investment stands out as one of the most solid financial decisions in today's real estate landscape. Owning a villa in Marbella or a beachfront apartment in Estepona allows you to consider a key question: should you monetise the asset through holiday rentals, or secure a steady cash flow with a long-term let?
The market has changed, and superficial analyses no longer suffice. In the current climate, shaped by the new Housing Law, stricter rental registries, and an increasingly demanding luxury tourist profile, we break down the latest data to reveal which model truly maximises your net returns.
Holiday rentals: A paradigm shift in short-stay models
The appeal of holiday rentals on the Costa del Sol is undeniable. With more than 300 days of sunshine a year and an international client profile boasting extraordinarily high purchasing power, luxury properties command record nightly rates. A luxury villa or an exclusive penthouse allows owners to apply aggressive dynamic pricing during the high season (June to September) and during key periods such as Easter week or autumn golf championships.
Unlike traditional rentals, holiday lets fall outside the scope of the national Housing Law (LAU); instead, regional rules set by the Junta de Andalucía and local councils govern them. Even so, the wider legal ecosystem still shapes the sector despite this regional and municipal framework. Indeed, INE figures from June 2026 confirm a paradigm shift: tourist properties in Spain have suffered a historic year-on-year drop of 10.7%.
Central government's new regulations drive this shift, particularly through the Single Digital Window and the reform of the Horizontal Property Law, which now allows residents' associations to veto this activity . Against this backdrop, buying a second-hand property purely to let it out to holidaymakers has become a financial game of Russian roulette.
New-build luxury developments, however, such as those Prime Invest markets, sidestep this risk: their statutes permit holiday lettings from the outset and comply with Single Digital Window requirements, safeguarding the investment.
Despite this adjustment in tourist housing, Andalusia still stands as the country's undisputed hub for residential tourism, leading Spain with over 90,600 active licences, with Málaga topping the list at provincial level. What might look like a market contraction at first glance is, in fact, excellent news for investors in new-build luxury property. The Costa del Sol market is seeing a reduction in mass-market accommodation in urban centres. As overall supply shrinks, prime-location luxury properties gain value, allowing owners to capture the most exclusive international demand and sustain considerably more competitive nightly rates.
Long-stay rentals: greater stability
Far from the uncertainty other regulations create, the recent Andalusian Housing Law (Law 5/2025) has shaped an extremely favourable playing field for investors on the Costa del Sol, particularly in the premium long-stay or mid-term segment.
First, the Andalusian law has introduced a landmark administrative simplification: it scraps the requirement to deposit rental contract deposits with the regional administration . This removes red tape and speeds up contract signing, restoring financial agility to both parties.
The new rules also give legal certainty to interesting new operating models such as luxury Coliving and Flexliving (temporary residences run by a professional operator), ideal for capturing the steady stream of international executives and digital nomads who choose the Costa del Sol to live and work for extended periods.
Holiday lets or long-stay rentals on the Costa del Sol: which is more profitable?
Both models offer extraordinary opportunities for monetisation, but the real factor behind success no longer lies in the rental type (holiday or long-stay); it lies in the nature and origin of the property itself.
Málaga leads the holiday rental market, where the 10.7% drop in mass urban supply has sent nightly rates for exclusive properties soaring. At the same time, the Andalusian Housing Law (5/2025) shields long-stay rentals by removing deposit-related bureaucracy and opening the door to profitable luxury Flexliving. Both options maximise returns by operating in a premium market that readily absorbs short and mid-term stays alike.
Ultimately, investors achieve maximum profitability by eliminating regulatory uncertainty. In the current context, buying a second-hand property to generate returns carries real financial risk. New-build properties, by contrast, stand out as the only fully protected and versatile investment.
