Student housing in Portugal: Shared housing as a shield against the housing crisis in 2026

The Portuguese property market is navigating unprecedented turbulence in 2026. Finding affordable accommodation has become a real obstacle course, particularly for students and young professionals. At Roomlala, we see the difficulties our community faces every day when trying to find a home in Portugal's major cities. Faced with rampant inflation and a structural shortage of housing, shared housing and homestays are no longer just economic alternatives: they have become a true anti-crisis shield. In this article, we break down the dynamics of this property crisis for you and explain how to take advantage of shared housing, whether you are a tenant looking for a room or a host keen to rent out safely.

Understanding the property crisis in Portugal in 2026

To fully grasp the scale of the phenomenon, we must face the figures. Portugal, a victim of its own success as a tourist destination and its appeal to digital nomads, has seen its property landscape change radically. Affordable entire homes have all but disappeared from the centres of Lisbon and Porto, pushing local tenants towards the outskirts or towards new accommodation solutions. At Roomlala, we observe that the demand for private rooms has literally exploded, turning the shared rental market into an ultra-competitive sector.

The shocking figures of rental inflation

The end of 2025 was marked by a record rise in property prices, reaching 18.9%. This surge has inevitably had an impact on the shared housing market. In the first quarter of 2026, the price of rooms in shared housing in Portugal increased by a further 8% year-on-year. Today, the median rent for a room is reaching new heights: expect to pay around 550 euros per month in Lisbon, 450 euros in Porto, and 335 euros in Coimbra, the university city par excellence. These figures, which were unthinkable just five years ago, weigh heavily on the budgets of households and students, whose grants and income have not followed the same upward curve.

The delay in public infrastructure: a market under pressure

Faced with this emergency, the Portuguese government launched the National Plan for Accommodation in Higher Education (PNAES), with the promise of delivering thousands of new student beds by 2026. Unfortunately, administrative delays and difficulties in the construction sector have significantly slowed down the delivery of these public residences. As a direct consequence, public supply is unable to absorb the demand, and students are turning en masse to the private rental sector. This imbalance maintains extreme tension in the market, making the private supply of shared housing and homestays absolutely essential in the long term. Concrete example: A student arriving from the Algarve to study at the University of Lisbon in September 2026 statistically has only a 15% chance of getting a place in a university residence. They will have to turn to a platform like Roomlala to find a room with a host.

Shared housing: much more than just a student matter

Historically associated with student life, shared housing has changed. It has become mainstream to provide a global societal response to the housing crisis. At Roomlala, we are noticing an unprecedented diversification in the profiles of our users. Rising interest rates and the tightening of conditions for access to mortgage credit are preventing an entire generation from becoming homeowners, while rents for individual apartments (one- or two-bedroom) have become inaccessible for an average Portuguese salary.

A sociological transformation of the market

Today, shared housing is no longer reserved for 20-year-olds. Faced with record property inflation, young professionals, precarious workers, and even some single-parent families are turning to this lifestyle in droves to mitigate the crisis. Sharing a large apartment not only allows for splitting the rent but also for sharing utility bills (water, electricity, internet), which have also increased significantly. This diversity of profiles creates new cohabitation dynamics, often very enriching, where students and young professionals share the same roof, exchanging tips and networks. Use case: Sofia, 32, a nurse in Porto, has chosen to rent a room in a large four-bedroom apartment with two other young professionals. This allows her to save 300 euros per month compared to renting a studio, a sum she is saving for a future property purchase.

The growing importance of homestays

Alongside traditional shared housing, the homestay model is seeing rapid growth. Many hosts, often elderly people or couples whose children have left the family nest, have empty rooms. Renting out these spaces allows these hosts to generate essential additional income in the face of inflation, while fighting against isolation. For the tenant, it is the guarantee of accommodation that is often better maintained, quieter, and provides an authentic immersion in Portuguese culture. We strongly encourage this practice, which recreates intergenerational social bonds while optimising existing urban space.

Hosts: secure your rental with the student tenancy agreement

While demand is high, renting out your property requires following a precise legal framework to avoid nasty surprises. Portuguese legislation has evolved to adapt to the specific needs of the student market. At Roomlala, we support our hosts so that they make the best contractual choices, thereby guaranteeing the profitability and flexibility of their property investment.

The advantages of the 9-month contract

Hosts should be particularly aware of the need to use the specific student tenancy agreement rather than a standard residential lease. This contract, the duration of which is aligned with the academic year (usually 9 months, from September to June), helps to protect hosts. It avoids complex disputes related to recovering the property during the summer period. By opting for this format, the host retains flexibility over their property: they can rent it to students during the school year, then offer it for short-term rental to tourists during the summer, thus maximising their income. Use case: João owns an apartment near the University of Coimbra. By using a 9-month student tenancy agreement, he ensures that his tenants will leave at the end of June. He can then carry out maintenance work in July and rent to holidaymakers in August, without the risk of being stuck with a standard long-term residential lease.

Fighting against informal rentals

A major point of vigilance in 2026 concerns the proliferation of informal rentals, i.e., without a declared contract. Although this may seem advantageous from a tax perspective in the short term, it is an extremely risky practice that is penalised by Portuguese law. Furthermore, a legal tenancy agreement registered with the tax authorities (Finanças) is mandatory for obtaining a visa for foreign students (particularly Brazilian or Lusophone African students, who are very numerous in Portugal). By refusing to draw up a legal contract, the host cuts themselves off from a huge portion of solvent and serious demand. At Roomlala, we make it a point of honour to promote transparent and secure rentals, protecting both the host and the tenant.

Tenants: how to avoid traps and find your ideal room

In a market as tight as Portugal's in 2026, rushing is the tenant's worst enemy. The scarcity of properties and the urgency of finding a roof over one's head before the start of the academic year create fertile ground for malicious individuals. It is crucial to adopt a rigorous methodology for your search for shared housing or a homestay.

Avoid online scams

Administrative delays in the construction of public residences are keeping extreme pressure on the private market, unfortunately favouring online scams. Fake listings, offering luxurious rooms at unbeatable prices in popular Lisbon neighbourhoods (such as Baixa or Alfama), are rife on social networks. Here are the red flags to never ignore:

• The host claims to be abroad and asks for a money transfer (via Western Union or cash order) even before the viewing.
• The price is abnormally low compared to the 2026 medians (550€ in Lisbon, 450€ in Porto).
• The lessor refuses to provide you with an official tenancy agreement.

At Roomlala, we secure your transactions. Payment is made online on our secure platform, and the money is only transferred to the host after you have moved in, which completely eliminates the risk of paying for a ghost property. Concrete example: Maria, a Brazilian student, almost lost 1000 euros in security deposit on a Facebook group. By using Roomlala, she was able to book her room from São Paulo with complete peace of mind, knowing that her money was protected until the keys were handed over in Porto.

Our advice for a solid application

To stand out in this hyper-competitive market, your profile and your application must be impeccable. Hosts receive dozens of requests per day. To maximise your chances:

• Complete your profile 100%: Add a smiling photo, a detailed description of your lifestyle (smoker/non-smoker, pets, hours) and your financial guarantees.
• Be responsive: Activate alerts and reply to messages from hosts as soon as possible.
• Prepare your documents: Always have a copy of your ID, proof of university enrolment, and proof of income for your guarantors ready.

In conclusion, the property crisis in Portugal in 2026 is a complex reality, but it is not inevitable. By prioritising shared housing and homestays via trusted platforms, and by scrupulously respecting legal frameworks (such as the 9-month student tenancy agreement), tenants and hosts can find a lasting and mutually beneficial common ground. We are here to support you at every stage of this life project.
