Spain and Portugal have built one of Europe’s strongest arguments for owning prime property and, at the same time, one of its strongest arguments for regulating it.
The contradiction is now impossible to dismiss. According to analysis reported by the Financial Times in August 2026, Portugal accumulated a housing shortfall of roughly 300,000 homes between 2021 and 2025, equivalent to around 6.6% of households. Spain’s deficit is estimated at approximately 700,000 to 750,000 homes, depending on methodology, compared with a eurozone gap of roughly 0.5%.
Yet scarcity has hardly weakened pricing. Spain’s official House Price Index rose 12.9% year on year in Q1 2026, while Portugal recorded 17.8% growth, the strongest annual increase in the European Union.
That is the tension shaping the Spain and Portugal property market now. Housing is becoming harder to produce, harder to afford and politically harder to leave untouched. Meanwhile, the same shortage continues to strengthen the scarcity value of well-located existing homes.
If you are considering buying in either country, the consequence sits far beyond headline price growth. You now need to assess regulation with the same seriousness you would give location, construction quality, ownership cost and eventual resale. Transfer taxes, residence policy, tourist-rental restrictions, planning rules and future measures aimed at second homes or foreign ownership are becoming part of the acquisition case.
The fundamentals remain compelling. The rules surrounding those fundamentals are becoming less predictable.
That is the Iberian paradox.
The shortage in both countries comes from structural constraints that cannot be solved through one construction cycle.
In Spain, Banco de España identifies inadequate housing supply as the principal factor behind current affordability pressure. During the first half of 2025, the country formed roughly 190,000 net new households while completing around 100,000 homes. OECD analysis adds another layer: between 2022 and 2024, Spain issued approximately 345,000 construction permits against roughly 604,000 additional households.
Planning is part of the problem. Development-ready land is slow to create, administrative procedures can stretch for years and construction productivity remains weak. Rising costs, labour shortages, modest developer margins and fragmented project delivery add further pressure.
The result is geographic concentration. Spain’s shortage carries the greatest weight in economically successful cities, coastal regions and tourism-heavy markets where household formation, migration and international demand all compete for limited stock.
Portugal faces a similar constraint through a different housing structure.
Portugal completed around 25,000 new dwellings in 2024, while Banco de Portugal notes that construction between 2015 and 2024 amounted to roughly half the volume produced during the previous eight-year period.
At the same time, the existing housing stock creates a politically awkward headline. In the 2021 census, approximately 19% of homes were classified as secondary residences and another 12% as vacant. Together, around 31% of dwellings were outside permanent occupation.
Economically, that figure requires context. An empty rural home or seasonal property in a low-demand region does little to solve housing pressure in Lisbon, Cascais or the Algarve. Politically, however, the distinction becomes easier to compress into a simpler argument: households are struggling to find homes while large numbers of properties sit outside permanent residential use.
That gap between economic reality and political perception matters because policy increasingly responds to the latter.
Search behaviour around Spain and Portugal is full of one recurring assumption: surely prices have to fall.
Current evidence points in the opposite direction.
Spain recorded 12.9% annual house-price growth in Q1 2026, with Madrid and the Balearic Islands both rising 13.6% and Andalusia 13.3%. Portugal’s 17.8% increase during the same quarter was the highest in the EU, compared with an EU average of 5.1%.
The mechanism is straightforward. Demand remains strong, new supply arrives slowly and prime locations have even less capacity to absorb additional development. Existing property therefore becomes progressively harder to replace.
Banco de España has previously found that prices rise faster in regions where relative housing scarcity is greater, which helps explain why affordability pressure and appreciation can strengthen simultaneously.
That relationship offers support for existing prime property, although it also creates the political conditions that make intervention more likely. Scarcity can protect your asset while making the ownership environment around it progressively less comfortable.
Foreign purchasing is a useful example of how national statistics can hide local political pressure.
Across Spain, foreign purchasers represented 13.52% of home transactions in Q4 2025, accounting for more than 24,200 purchases during the quarter. At national level, that hardly suggests international capital controls the market.
Move closer to the coast and the picture changes sharply.
Foreign purchasers accounted for approximately 42.91% of transactions in Alicante, 31.47% in the Balearic Islands, 31.11% in Málaga, 26.44% in Santa Cruz de Tenerife and 24.80% in Girona. Spanish Land Registrars explicitly identify the relationship between tourism intensity and higher foreign-buyer participation.
That concentration matters because housing policy is increasingly shaped locally.
Portugal shows a similar dynamic. Foreign nationals accounted for approximately 28% of residential purchases in 2025, according to Banco de Portugal data reported in May 2026. That figure includes foreign nationals who already live in Portugal, so it should never be treated as evidence that 28% of homes were bought by overseas investors.
Still, the political consequence is clear. International participation becomes most visible in the markets already experiencing the strongest affordability pressure.
Portugal moved from debate into legislation in May 2026.
Decree-Law 97/2026 introduced a 7.5% IMT transfer-tax rate for many non-residents acquiring residential property, with exceptions covering certain previous residents, people who become Portuguese tax resident within two years and qualifying moderate-rental use.
The strategic significance is larger than the tax rate itself.
Residency status now changes the economics of buying Portuguese residential property. For an international owner purchasing a second home while remaining tax resident elsewhere, that creates a direct additional cost at acquisition.
Portugal has therefore chosen a relatively measured form of intervention. Foreign ownership remains available, while some categories of non-resident ownership have become more expensive.
That distinction matters because the underlying property market remains attractive. The political response is targeting the structure of ownership, not removing the market altogether.
Spain’s political signal has been louder and less settled.
Prime Minister Pedro Sánchez proposed a tax of up to 100% on residential purchases by certain non-EU buyers. By March 2026, the measure remained stalled in parliament because the government lacked sufficient support.
So the practical position is clear: Spain did not introduce a 100% foreign-buyer property tax.
The proposal still matters.
If your intended ownership horizon is ten or twenty years, current legislation gives you only part of the picture. Political direction matters because a proposal capable of reaching national debate tells you how housing affordability is being framed and which forms of ownership may become easier targets in future.
Spain’s policy environment has already changed once in a material way.
Spain formally abolished investor residence visas from 3 April 2025, including the former property-linked route.
The measure matters less as an immigration detail than as evidence of a broader political shift.
A decade ago, property-linked residence policy was designed to attract international capital. Housing affordability has since changed the political framing, and incentives once promoted as economically useful are now being reconsidered through their effect on domestic housing access.
For you, that means residency strategy should be separated from property strategy much earlier in the process. An excellent home can still make sense. The purchase simply carries fewer ancillary benefits than it once did.
Tourist rentals show the same shift at municipal level.
Short-term letting has become one of the clearest areas where regulatory exposure depends on postcode.
Barcelona plans to allow more than 10,000 existing tourist-let licences to expire, with those homes expected to return to conventional residential use by the end of 2028. Málaga has already restricted new holiday-rental permits in dozens of neighbourhoods where tourist accommodation has become highly concentrated.
Those policies affect different owners in very different ways.
A coastal residence purchased primarily for family use may experience little financial disruption from stricter tourist-rental rules. An apartment bought on the assumption that short-term income will cover a significant portion of the holding cost faces a materially different risk.
The intended use of the property therefore needs to enter your regulatory analysis from the outset. Rental permission can no longer be treated as an incidental extra attached to a desirable location.
The same principle applies to development.
This is where the contradiction becomes especially uncomfortable.
Portugal’s Q1 2026 Investment Property Survey recorded 84% pressure from construction costs, 83% from bureaucracy and licensing and approximately 70% from taxation.
APPII goes further, estimating that around 59,000 pre-certified homes failed to proceed during the previous three years because the projects were economically unviable. Its leadership argues that current cost structures make it extremely difficult in major urban markets to deliver homes for sale around €300,000, while higher-priced development can absorb the same fixed costs more easily.
Spain shows a similar pattern. OECD analysis points to expensive land, construction costs, labour shortages, financing constraints, slow approvals and policy uncertainty as pressures on project viability, especially in affordable and rental housing.
That creates a policy problem with direct property-market consequences. The housing segment under greatest social pressure can become the least attractive to build, while higher-value development remains economically viable.
Scarcity then persists, which supports existing values and invites further intervention.
National policy sets the framework, but your actual exposure increasingly depends on location.
Barcelona sits at the sharper end of the spectrum. High housing pressure, aggressive tourist-rental policy and strong municipal intervention create a high political exposure environment.
The Balearic Islands deserve a similar reading. Foreign-buyer penetration is exceptionally high, buildable land is constrained and tourism, second-home ownership and environmental limits remain politically sensitive.
Lisbon also sits in the high-exposure category because extreme affordability pressure combines with fast price growth, substantial foreign participation and Portugal’s new non-resident IMT structure.
The Algarve carries medium-to-high exposure. International demand and second-home use are significant, while direct urban affordability pressure is less intense than in Lisbon.
Madrid presents a different picture. The domestic economy is deep, prime supply remains constrained and tourism plays a smaller role in the broader housing story. Political exposure therefore sits closer to medium.
Marbella and the Costa del Sol combine heavy international demand with growing affordability concerns, yet regional policy remains less interventionist than Barcelona’s. That keeps exposure around medium for now.
Cascais and Estoril also warrant a medium assessment. Severe supply constraints and strong international demand support values, while national Portuguese tax policy reaches these markets directly.
The lesson is simple: political risk in property has become increasingly postcode specific.
This distinction is probably the most important one in the entire article.
A higher transfer tax changes your acquisition cost. It does not automatically weaken the scarcity of an exceptional coastal home.
A tourist-rental restriction can materially reduce income potential while leaving the value of a prime owner-occupied residence largely intact.
Stricter planning may make development harder and simultaneously increase the replacement value of existing completed property.
Political intervention therefore enters the ownership equation through several channels: acquisition cost, annual holding cost, rental income, property use, renovation rights, development potential, liquidity and eventual resale.
That means your due diligence now needs to ask a broader question.
How well does the property hold up once regulatory friction is priced in?
For a home intended for twenty years of family use, the answer may remain highly favourable. For a leveraged short-term rental strategy relying on stable municipal rules, the same market can look considerably less attractive.
Current fundamentals still support a strong case for well-selected property in both countries.
Demand remains robust, supply remains constrained and official data show double-digit annual price growth. Those conditions make a broad market correction difficult to assume from current evidence alone.
The risk profile has changed, however.
Non-resident ownership is becoming more expensive in parts of Portugal. Spain has already removed its property-linked investor residence route and continues to debate tougher measures around certain forms of foreign ownership. Tourist-rental rules are tightening in pressured municipalities, while planning and development regulation continue to affect future supply.
So the answer depends heavily on why you are buying.
If your priority is long-term personal use in a supply-constrained prime location, scarcity can still work strongly in your favour. If your purchase depends on short-term rental income, tax efficiency or regulatory privileges remaining unchanged, the margin for error has narrowed considerably.
That is where the political dimension belongs in your acquisition analysis: beside the property fundamentals, not in place of them.
Spain and Portugal have created a difficult equation.
Scarcity supports prices. Rising prices deepen affordability pressure. Affordability pressure increases political intervention. Intervention then changes the cost, use and structure of ownership.
For international owners, that does not make Spain or Portugal structurally unattractive. It makes regulatory durability part of property quality.
A home with protected views, constrained local supply and a deep future buyer pool can remain highly defensible even as acquisition taxes rise or rental rules tighten. Another property may lose much of its economic logic once regulatory assumptions change.
That is the distinction worth underwriting now.
The Spain and Portugal property market still offers some of Europe’s strongest residential fundamentals. The harder question is whether the ownership structure around your chosen property will remain equally attractive over the years you intend to hold it.
And that is where serious acquisition advice begins.

The stronger choice depends on your intended use, tax position and location. Spain offers deeper residential markets and broader prime inventory, while Portugal can provide a different ownership and tax framework. Recent policy changes in both countries make jurisdictional analysis increasingly important alongside property quality.
Current national data says no. Spain’s official House Price Index increased 12.9% year on year in Q1 2026, with several prime and coastal regions recording even stronger annual growth.
No at national level based on the latest available official data. Portugal recorded 17.8% annual house-price growth in Q1 2026, the highest rate in the European Union during that period.
Yes. Portugal introduced a 7.5% IMT transfer-tax rate for many non-resident residential acquisitions in 2026, subject to specific exceptions. Residency status can therefore materially affect the cost of purchasing Portuguese property.
No. Spain proposed a tax of up to 100% on certain residential purchases by non-EU buyers, but the measure remained stalled in parliament in 2026 and had not become law.
