Portugal Is Failing to Build Enough Homes

Portugal has accumulated a housing shortfall of more than 300,000 homes since 2014 as household formation repeatedly exceeded residential completions. Prices have nearly doubled since 2019, while the recent recovery in permits has yet to produce enough finished properties to restore balance.

Portugal’s housing deficit exceeds 300,000 homes

Portugal’s main property-market risk is no longer a possible future fall in prices but the continuation of chronically weak construction. Paulo Lopes, chief executive of Casaiberia, made that argument in a column published by The Portugal News, drawing on Morningstar DBRS research comparing new household formation with completed homes. The accumulated gap since 2014 is estimated at more than 300,000 properties.

The figure does not represent an exact count of homeless households. It measures the cumulative difference between estimated additional housing needs and new supply. Some demand is absorbed by existing properties, shared family homes, rented rooms and migration to lower-cost regions. The prolonged imbalance nevertheless helps explain why higher mortgage rates did not trigger a broad price correction.

Demand may moderate over the next few years. Immigration could slow, banks may maintain stricter affordability tests, and high prices are already excluding households from the purchasing market. Supply, however, is constrained by labour shortages, costly materials, limited serviced land and slow municipal planning procedures.

Prices have risen faster than construction

Portugal’s House Price Index increased by 19% in 2025. Existing homes gained 18.9%, compared with 14.2% for newly built properties. A total of 169,812 homes changed hands for €41.2 billion. Transaction numbers increased by 8.6%, while their total value rose by 21.7%, indicating a sharp increase in the average amount spent.

The median transaction price reached €2,076 per square metre, 16.8% above the 2024 level. The difference between median-price growth and the national index reflects methodology: the index adjusts for the characteristics of properties, while the median is affected by location, floor space and the composition of annual sales.

During the fourth quarter, the median reached €2,198 per square metre, an annual increase of 17.5%. Prices rose in 24 of Portugal’s 26 statistical subregions, demonstrating that the escalation was not confined to Lisbon, Porto or the Algarve.

The increase continued into 2026. Prices gained 17.8% year on year in the first quarter, even as transaction numbers fell by 8.7%. Fewer sales have not yet forced sellers to make significant reductions because active buyers are still competing for a limited stock of available homes.

Portugal completed only 30,000 homes

Construction indicators improved in 2025, but delivery remained small relative to the accumulated shortfall. Portugal completed an estimated 30,425 dwellings, 8.7% more than in the previous year. The number of completed buildings declined by 3% to 16,964, suggesting that a greater proportion of delivery may be coming from larger multi-unit developments.

Authorities issued permits for 48,844 dwellings, a 14.6% increase and the highest figure since 2011. The number of permitted buildings rose by only 1.4% to 26,227. The gap between almost 49,000 authorised homes and just over 30,000 completions points to a potential construction pipeline, but permits do not guarantee financing, a start date or final delivery.

At a completion rate of about 30,000 homes per year, it would take a decade to produce an additional 300,000 properties even if current household needs were already being met. The real period would be longer because household formation and the replacement needs of the existing stock continue to evolve.

Portugal completed 6,931 new family dwellings during the first quarter of 2026. Permitting activity weakened over the same period, indicating that the recovery may remain uneven after the stronger full-year figures recorded in 2025.

Planning remains a central obstacle

Portugal’s formal building rules broadly incorporate international good practice, but implementation remains slow and unpredictable. Municipal authorities often lack administrative capacity and digital systems, while secondary local rules can make procedures difficult to navigate. Delays weigh most heavily on small and young developers unable to finance land for years before construction starts.

The Organisation for Economic Co-operation and Development also identifies persistently weak housing investment, limited construction productivity and shortages of skilled workers. Changes to spatial planning have reduced the volume of developable land and may have contributed to higher land values. The organisation recommends more flexible planning, simpler permitting and stronger taxation of underused properties.

New housing construction costs increased by 6.9% year on year in May 2026. Rising labour and material costs reduce the number of commercially viable developments and encourage builders to focus on higher-priced properties where expenses can more easily be passed to buyers.

Portugal may therefore continue to lack affordable homes even when visible building activity rises. A development aimed at wealthy residents or international buyers increases the total housing stock but does little for households unable to meet market prices.

Foreign buyers are not the only driver

International purchasers have a visible influence in Lisbon, the Algarve, Porto and Madeira, but nationwide data show that the market cannot be explained by foreign demand alone.

Buyers with tax residence outside Portugal purchased 8,471 homes worth €3.4 billion in 2025. The number of acquisitions fell by 13.3%, while their total value declined by 2.1%. Non-residents accounted for about 5% of properties sold, although their share of transaction value was higher because they tended to purchase more expensive homes.

Restrictions on foreign buyers could reduce competition in selected premium districts but would not create new family housing. Policymakers also face the challenge of distinguishing purchases of scarce existing properties from foreign capital financing new construction or the rehabilitation of derelict buildings.

Household debt differs from the previous crisis

Rapid price appreciation has prompted concerns about a housing bubble, but Portugal’s financial position differs from the years preceding its debt crisis. Household debt has fallen from approximately 100% of disposable income in 2008–2012 to about 50% in 2025. Morningstar DBRS considers it premature to describe the current market as a traditional debt-driven bubble.

Risk has not disappeared. Valuations are elevated relative to household income, and affordability continues to deteriorate. The strain may appear through lower worker mobility, delayed household formation and emigration rather than a wave of mortgage defaults.

Buyers entering at the limits of affordability, including some using public mortgage guarantees, would be vulnerable to an economic slowdown or a reduction in income. Banks may remain resilient even while individual borrowers experience significant pressure.

The average interest rate on outstanding housing loans declined to 3.065% in May 2026, while bank housing valuations increased by 17.1% year on year. Lower financing costs support demand, but rising valuations can also allow larger loans and reinforce price pressure when supply remains fixed.

Rental costs are following property prices

Households unable to buy are remaining in rented accommodation for longer. The median rent under new contracts reached €9.29 per square metre in 2025. It increased to €9.46 in the first quarter of 2026, 9.1% above the same period a year earlier. Lisbon, Porto and tourism-heavy municipalities remain substantially more expensive than the national median.

Portugal’s formal rental sector is relatively small and fragmented. Only about 12% of households rented their homes in 2022, one of the lowest shares among developed economies. Frequent regulatory changes, differences between old and new contracts and a large informal market reduce predictability for both landlords and tenants.

Rent caps can protect existing tenants in the short term, but without additional supply they may reduce the number of properties available to new renters. A longer-term response requires private and municipal rental construction, stable regulation and targeted support for low-income households.

Buyer assistance is supporting demand

The Construir Portugal programme includes tax relief for first-time buyers aged 35 or younger and a public mortgage guarantee. Eligible young buyers can receive a full exemption from property transfer tax and stamp duty for a permanent home costing up to €324,058, with partial relief up to €648,022. The state guarantee can cover 15% of a mortgage for a property valued at up to €450,000.

These measures lower initial purchasing costs and help selected households enter the market. In a supply-constrained system, however, part of the benefit can be capitalised into higher prices. Demand assistance must therefore be matched by faster construction if it is to improve affordability rather than redistribute scarcity.

Portugal also needs a larger social and affordable rental stock. Decades of limited public investment have left social housing provision among the smallest in the OECD. Expanding it requires land, funding, contractors and sufficient municipal capacity to manage completed properties.

The shortage is becoming an economic risk

Housing is increasingly affecting Portugal’s competitiveness. Employers struggle to recruit workers in Lisbon, Porto and tourism centres when rent absorbs a large share of wages. Universities face accommodation shortages, while younger professionals may choose emigration over unaffordable housing at home.

A 2023 survey found that 44% of respondents had considered leaving Portugal because of difficulties finding affordable housing. The result does not predict actual departures but illustrates the role of housing costs in decisions about employment, education and family formation.

For investors, chronic undersupply supports the value of existing assets but raises political and regulatory exposure. As the gap between prices and local incomes widens, governments face greater pressure to tax vacant properties, restrict short-term rentals and strengthen tenant protections.

As International Investment experts report, Portugal is facing an accumulated structural shortage rather than a temporary reduction in listings. Higher permit numbers and government programmes will matter only when authorised projects become completed, affordable homes faster than new households are created. Mortgage support without a comparable supply response risks lifting prices further, making sustained residential completions—not the number of announced initiatives—the essential measure of housing-policy success.
