Spain’s luxury property market continues to reach new heights, with the Balearic Islands now accounting for 15 of the country’s 25 most expensive municipalities to purchase a home.
According to September 2026 data from property portal pisos.com, the islands dominate Spain’s premium residential market, with Formentera leading the national rankings at an average asking price of €10,332 per square metre.
The findings highlight the extraordinary price growth experienced across Mallorca, Ibiza, Formentera and Menorca, where limited housing supply and demand from high-purchasing-power buyers continue to shape the market.
Formentera Becomes Spain’s Most Expensive Property Market
Formentera has secured its position as Spain’s most expensive municipality for residential property.
With average asking prices reaching €10,332 per square metre, a 100-square-metre property would be advertised for approximately €1.03 million.
The island is the only municipality in Spain where average asking prices exceed €10,000 per square metre.
Santa Eulària des Riu in Ibiza follows at €9,027 per square metre, while Andratx in Mallorca ranks third at €8,543.
The Balearic Islands occupy all seven of the most expensive positions nationally, demonstrating the strength of their premium property markets.
Spain’s Most Expensive Property Locations in 2026
According to the September 2026 figures, the following municipalities are among Spain’s most expensive residential markets:
| Municipality | Average Asking Price per m² |
|---|---|
| Formentera | €10,332 |
| Santa Eulària des Riu | €9,027 |
| Andratx | €8,543 |
| Sant Josep de sa Talaia | €7,879 |

| Marbella | €6,024 |
| Santa Maria del Camí | €5,763 |
| Santanyí | €5,621 |
| Benahavís | €5,479 |
Marbella and Benahavís are the two Andalusian municipalities appearing among Spain’s 25 most expensive property markets.
Their inclusion highlights the Costa del Sol’s continued position alongside the Balearic Islands as one of Spain’s leading destinations for premium residential property.
Property Prices Have More Than Doubled in Parts of Mallorca
Perhaps the most striking finding is the pace of price growth recorded in several Mallorcan municipalities over the past five years.
Since 2021, three locations have experienced increases exceeding 100%.
Andratx: +122.1%
Santa Maria del Camí: +107.9%
Sóller: +106.1%
Other municipalities have also recorded substantial increases.
Bunyola has experienced price growth of 80.8%, while Sant Lluís in Menorca has risen by 72.5%.
Santa Eulària des Riu in Ibiza has recorded an increase of 68.9%.
These figures demonstrate how property values in some of Spain’s most desirable coastal and island locations have changed considerably within a relatively short period.
What’s Driving Property Prices Higher?
According to Ferran Font, director of research at pisos.com, the price increases reflect several structural characteristics of the Balearic property market.
One of the most significant factors is the limited availability of developable land.
As island destinations, the Balearics face geographical constraints that restrict opportunities for residential expansion.
Planning regulations further limit the development of new housing, contributing to a restricted supply of properties.
At the same time, buyers with substantial purchasing power compete for homes in desirable locations.
This combination of constrained supply and high-value demand has contributed to significant increases in asking prices.
However, the trend also raises concerns about housing affordability for local residents, particularly workers in essential services and the hospitality sector.
Marbella and Benahavís Remain Among Spain’s Premium Markets
Although the Balearic Islands dominate the rankings, the Costa del Sol continues to feature prominently.
Marbella ranks among Spain’s ten most expensive municipalities, with average asking prices reaching €6,024 per square metre.
Neighbouring Benahavís also appears in the national top 25, at €5,479 per square metre.
Both municipalities are established luxury residential destinations, offering premium villas, gated communities, golf properties and coastal developments.
Their presence in the rankings reinforces the Costa del Sol’s importance within Spain’s high-end property sector.
While the Balearic Islands face particular geographical limitations, Marbella and Benahavís operate within a broader mainland market, offering buyers access to a wider geographical area and a diverse range of residential developments.
What Does This Mean for Real Estate Professionals?
The latest figures highlight the increasing importance of understanding individual property markets rather than viewing Spain as a single residential destination.
Prices can vary substantially between municipalities, even within the same region.
For estate agents working with international buyers, accurate local market knowledge is becoming increasingly valuable.
Buyers considering properties in Mallorca, Ibiza or Marbella may be comparing several destinations before making a purchasing decision.
Understanding differences in pricing, property availability, lifestyle and long-term market conditions can help agents provide more informed advice.
The figures also demonstrate the importance of distinguishing between advertised property prices and completed transactions.
While asking-price data provides an indication of market expectations, final sale prices may differ.
The NLS Perspective: A More Connected Spanish Property Market
The concentration of Spain’s most expensive municipalities within the Balearic Islands highlights the diversity of the country’s residential market.
From Formentera and Ibiza to Marbella and Benahavís, individual destinations attract buyers with different requirements, budgets and lifestyle preferences.
For real estate professionals, this creates opportunities to collaborate across regional boundaries.
An international buyer initially considering Mallorca may also explore Marbella, while someone searching along the Costa del Sol may be interested in properties elsewhere in Spain.
The NLS is designed to support this interconnected market by bringing real estate agencies together, improving property visibility and encouraging collaboration between professionals across Spain.
As property markets become increasingly competitive, access to verified listings, reliable information and wider agency networks can help professionals connect buyers with suitable opportunities.
The latest rankings reinforce one important message: Spain’s luxury property market extends far beyond any single destination, and collaboration across regions is becoming an increasingly valuable advantage.
