In the Oct 2025 registry snapshot for apartment transactions, the highest recorded foreign-buyer share in this cut is concentrated in Costa Blanca municipalities. Torrevieja, Orihuela, Pilar de la Horadada, Guardamar del Segura and a wider cluster of Alicante-area markets all show a foreign-buyer share of 46.91%, underscoring how international demand is concentrated in a specific coastal corridor rather than spread evenly across Spain.

This is registry-based evidence rather than anecdote: the underlying series comes from MIVAU’s sold-transactions dataset using buyer-residency methodology. For cross-border investors, agents and policy researchers, that makes the pattern useful as a map of where international participation is already deeply embedded in the apartment market.

Costa Blanca dominates the foreign-buyer map

In the Oct 2025 snapshot, the standout feature is not a single city but a dense coastal cluster. That matters because foreign demand in housing markets often concentrates where relocation infrastructure, second-home stock and international brokerage networks are already established.

The cities in this cut all post the same foreign-buyer share of 46.91%. The list includes Torrevieja, Orihuela, Pilar de la Horadada, Guardamar del Segura, Rojales, San Miguel de Salinas, Algorfa, Benijófar, San Fulgencio, Dolores, Finestrat, Benidorm, Villajoyosa / La Vila Joiosa, Altea and Polop.

The common thread is geographic concentration rather than dispersion across multiple Spanish regions. For readers tracking foreign capital flows, this suggests the strongest international footprint in this snapshot sits in Alicante-province apartment markets rather than in a broad national spread.

Foreign demand shows up across both large resorts and small municipalities

In the Oct 2025 snapshot, international participation is clearly not limited to major brand-name resort cities. That is a familiar market pattern in coastal Spain, where foreign-buyer ecosystems often extend from anchor destinations into smaller nearby municipalities.

At the larger end of this list, Torrevieja has a population of 98,533, Orihuela 84,560 and Benidorm 77,327. But the same 46.91% foreign-buyer share also appears in much smaller places such as Benijófar with 3,679 residents, Algorfa with 3,788, Polop with 5,828 and San Miguel de Salinas with 7,177.

That spread matters operationally. For brokers and investors, it indicates that foreign demand is not just a city-centre or skyline phenomenon; it reaches into lower-population municipalities that sit within the same coastal living and holiday-home orbit. For policy analysts, it also means international demand pressure can be highly localised even where absolute population is small.

Prices vary widely even where the foreign-buyer share is identical

In the Jul 2026 asking-price snapshot, the price ladder across these cities is broad despite the same foreign-buyer share in the sold-transactions cut. That is a useful reminder that international demand can attach to very different product mixes, from lower-ticket resale stock to higher-priced coastal apartments.

At the lower end of the median sale-price range in this cut, San Fulgencio stands at €158,691 and Torrevieja at €224,609. Mid-market examples include Orihuela at €231,933, Dolores at €246,581, San Miguel de Salinas at €256,347 and Guardamar del Segura at €268,554.

At the higher end, Pilar de la Horadada reaches €300,292, Rojales €310,058, Benijófar €319,823, Benidorm €332,031, Finestrat €351,561, Villajoyosa / La Vila Joiosa €358,885 and Altea €378,417.

For readers comparing entry points, that means the same foreign-demand intensity does not map to a single price band. Some markets in this cluster remain relatively accessible by coastal standards, while others sit firmly in a premium bracket.

The registry count shows this is a meaningful transaction base, not a niche signal

In the Oct 2025 registry snapshot, the series reports 13,958 sold transactions alongside an average price of €195,888. That matters because foreign-buyer analysis is more useful when it comes from recorded market activity rather than isolated luxury deals or promotional narratives.

The count reinforces that this is a substantial transaction dataset tied to buyer residency in the official registry framework used by MIVAU. For market participants, that gives the foreign-buyer share a firmer footing than anecdotal claims about who is buying on the coast.

The methodological point is also important: this is a residency-based registry measure of buyers in sold transactions. That makes it a strong indicator of where international participation is visible in official records, even if some non-resident activity may be routed through local corporate structures and therefore not always appear in the most intuitive way to end users.

For cross-border buyers, the key takeaway is concentration rather than universality

In the Oct 2025 snapshot, the practical takeaway is that foreign demand is heavily concentrated in a recognisable coastal corridor. In housing markets, that kind of clustering often creates self-reinforcing visibility because buyers, agents, services and resale comparables are easiest to find where an international market already exists.

Torrevieja and Orihuela combine the 46.91% foreign-buyer share with relatively large populations of 98,533 and 84,560, making them stand-out reference points for scale. At the same time, Altea at €378,417, Villajoyosa / La Vila Joiosa at €358,885 and Finestrat at €351,561 show that premium pricing also sits inside the same foreign-demand geography.

The result is a two-speed picture within one corridor: broad international participation across many municipalities, but with very different price positioning from one local market to the next. For anyone screening Spanish apartment markets through the lens of foreign demand, this snapshot points decisively to the Alicante coast as the main concentration zone in the data provided.
