The Costa del Sol’s ‘Golden Triangle’ has become one of the biggest hotspots for ultra-luxury homes in Spain.

The three towns of Marbella, Benahavis and Estepona now account for 95% of Malaga’s high-value properties, according to data from valuation firm Tecnitasa.

Marbella alone represents almost 60% of the province’s luxury housing supply, highlighting its continued dominance among wealthy international buyers.

The findings were presented during a property industry conference held in Marbella this week, where experts examined the changing demands of high-net-worth buyers and the increasingly distinct nature of the luxury housing market.

According to Tecnitasa, the benchmark price for luxury residential property across Malaga province now stands at approximately €8,000 per square metre.

However, in the Golden Triangle, prices typically range between €14,000 and €16,000 per square metre.

Some exclusive beachfront developments have even surpassed €40,000 per square metre, meaning a 200-square-metre apartment could theoretically command a price exceeding €8million at that rate.

The region is also playing an outsized role in Spain’s wider luxury property market.

Tecnitasa’s research found that Malaga province accounts for 32% of all Spanish properties listed for more than €3million.

Together, Malaga and the Balearic Islands represent almost 70% of the country’s supply in this ultra-luxury price bracket.

Meanwhile, luxury property prices across Spain increased by an average of 10.87% during 2025, according to the company’s study.

Industry experts say the market is being transformed by international demand, limited housing supply and changing expectations among affluent buyers.

Pedro Soria, director of Tecnitasa’s consultancy division, explained that luxury property can no longer be assessed using the same criteria as conventional housing.

While location remains crucial, buyers are increasingly prioritising privacy, wellbeing, personalised services and the overall lifestyle associated with a property.

The company believes the traditional idea of luxury, once closely associated with extravagance and ostentatious displays of wealth, is gradually giving way to more discreet forms of exclusivity.

Buyers are placing greater value on the quality of living spaces, their surroundings and the experience of owning a home.

The Costa del Sol is particularly well positioned to benefit from these changing preferences.

Its climate, international transport connections and established luxury infrastructure allow wealthy buyers to spend longer periods in southern Spain, often combining residential living with professional commitments.

Marbella, Benahavis and Estepona

Although the three municipalities dominate the province’s luxury market, Tecnitasa says they appeal to different types of purchasers.

Marbella remains the internationally recognised flagship destination, benefiting from its reputation, prestigious residential developments and established high-end lifestyle.

Benahavis, meanwhile, is particularly attractive to buyers seeking privacy, tranquillity and proximity to nature.

Estepona has emerged as an increasingly important destination thanks to its growing supply of newly developed luxury properties.

Together, the three locations offer a range of options for wealthy purchasers, from beachfront apartments and exclusive villas to secluded hillside estates.

Younger buyers and longer stays

The profile of the typical luxury property buyer is also changing.

Tecnitasa says affluent purchasers are increasingly younger, better informed and more willing to compare destinations across different countries before making a decision.

International buyers are also spending longer periods in their Spanish properties, rather than using them exclusively for short holidays.

This shift is increasing demand for services such as property maintenance, management and personalised assistance when owners are away.

Such considerations can now influence purchasing decisions almost as much as the property itself.

Financing also continues to play a role, despite the substantial wealth of many buyers.

According to Tecnitasa, some high-net-worth purchasers use mortgages as part of broader wealth management strategies, allowing them to preserve liquidity or spread investments across different assets.
