How to rent a flat in Portugal: a step-by-step guide for foreigners

Finding a place to live is one of the biggest challenges of moving to Portugal. Rents in Lisbon and Porto have risen sharply, good flats go quickly, and landlords often ask foreigners for more money upfront.

But it's absolutely doable with the right preparation. This guide walks you through how to rent an apartment in Portugal: where to search, what documents you need, how much to budget, how the contract works, your rights as a tenant, and the scams to avoid.

Quick summary:

• You'll need a NIF, ID, and proof of income.
• Budget for first month's rent + deposit + advance rent – often 3–5 months' rent upfront.
• Always sign a written contract and make sure it's registered with Finanças.
• Never pay before seeing the flat (or having someone you trust see it).
• Best months to search: February–June and October–November.

Step 1: Get Your NIF

You can't sign a rental contract in Portugal without a NIF (tax number). Get it first – at a Finanças office, online through a representative, or via gov.pt services for migrants. Non-EU residents without a Portuguese address may need a fiscal representativeA tax representative who deals with the Tax Authority on behalf of a non-resident. Whether you need one depends on your situation — check the Portal das Finanças..

Step 2: Set Your Budget

Typical monthly rents (2026, long-term)

Portuguese flat names: T0 = studio, T1 = one bedroom, T2 = two bedrooms, and so on. "T1+1" means one bedroom plus a small extra room.

Other monthly costs

• Electricity, water, gas: €80–€150
• Internet and mobile: €30–€60
• Condominium fees (condomínio): usually paid by the landlord, but check

Step 3: Where to Search

• Idealista – the biggest property portal in Portugal
• Imovirtual and Casa Sapo – other major portals
• OLX – private landlords (be extra careful of scams)
• Uniplaces, Spotahome, HousingAnywhere – medium-term rentals, often furnished, bookable online
• Facebook groups for expats and city-specific rentals
• Real estate agencies (imobiliárias) – Remax, ERA, Century 21, and local agencies
• Relocation agents – they search, attend viewings and check contracts for a fee

Tip: set up instant alerts on Idealista. Good flats can be rented within hours.

Best time to search

February to June (except around Easter) and October to November. Avoid August (holidays) and December. In summer, many landlords prefer tourist rentals, so long-term options dry up.

Step 4: Prepare Your Documents

Have these ready before viewing – landlords often choose the first tenant who can sign:

• Passport or residence permit
• NIF
• Proof of income: employment contract, recent payslips, or bank statements
• IRS tax declaration (if you've filed in Portugal)
• For remote workers or retirees: proof of foreign income and savings
• Guarantor (FiadorA guarantor who agrees to pay your rent if you cannot. Landlords may ask for one, or for extra months paid in advance instead.) – a Portuguese resident who guarantees the rent, if asked

No guarantor?

Many foreigners don't have a Portuguese guarantor. Alternatives:

• Paying more rent in advance
• A bank guarantee (garantia bancária)
• Rental guarantee insurance

Step 5: Deposits and Upfront Costs

At signing, you'll usually pay:

• First month's rent
• Security deposit (CauçãoThe security deposit for a rental, returned at the end of the lease minus any agreed deductions.)
• Advance rent (rendas antecipadas)

Under current law, landlords can ask for up to two months' deposit and up to two months' rent in advance. In practice, some still ask for more.

Law under review: in 2026, the government approved changes to the main rental law (NRAU), and in September 2026 parliament approved a reform bill in principle. It could remove the deposit cap, allow up to three months' rent in advance and change renewal rules. It isn't law yet – check the latest rules before signing. Check

Legal limits, fair deductions and how to get the money back are covered in our guide to rental deposits in Portugal.

Agency fees: in Portugal, the agency fee is normally paid by the landlord, not the tenant.

Step 6: View the Flat

Check carefully for:

• Humidity and mould – very common in Portuguese homes, especially in winter
• Heating – many flats have none; ask about heaters, heat pumps or insulation
• Windows – double glazing makes a big difference
• Water pressure and hot water (gas boiler, electric water heater or heat pump)
• Appliances included
• Noise – street, neighbours, nightlife
• Mobile signal and fibre internet availability
• Energy certificate (certificado energético) – landlords must provide it

Step 7: Sign the Rental Contract (Contrato de Arrendamento)

Always sign a written contract. Never accept an informal arrangement "to save on taxes" – you'll have no protection and no proof of address for residency, bank or health service registration.

The contract should state:

• Names and NIFs of both parties
• Address and description of the property
• Duration and renewal terms
• Monthly rent and payment date
• Deposit and advance rent
• Who pays utilities and condominium fees
• Notice periods
• Inventory of furniture and appliances

Contract types

• Fixed-term (prazo certo) – the most common, often 1–3 years. Fixed-term housing contracts generally renew automatically unless one party gives notice.
• Temporary contracts for students or work assignments – must clearly state the temporary purpose.

Registration with Finanças

The landlord must register the contract with Finanças and issue electronic rent receipts. Since 2025, tenants can register the contract themselves if the landlord doesn't. A registered contract is important for:

• Residency applications (AIMA)
• IRS deductions on rent
• Rent support programmes

Step 8: Move In

• Do a check-in inventory with photos and video of every room.
• Transfer utilities to your name or confirm they stay with the landlord.
• Set up internet (MEO, NOS, Vodafone, Digi).
• Get an Atestado de residênciaA proof-of-residence certificate issued by your parish council (Junta de Freguesia). Some registrations accept it as proof of address. from your Junta de FreguesiaThe parish council — the most local level of government. It issues certificates such as the atestado de residência. if needed.
• Update your address with Finanças, Segurança Social and your bank.
• Consider contents and liability cover – it's cheap, and a leak from your flat can make you liable for the neighbour's damage.

Tenant Rights in Portugal

• Rent increases during a contract are limited by law to an annual coefficient published by the government.
• Terminating early: tenants can usually end a fixed-term contract after one-third of the term has passed, with written notice (typically 120 days for contracts of a year or more, 60 days for shorter ones).
• Repairs: the landlord is responsible for structural repairs and keeping the property habitable.
• Deposit: must be returned at the end of the contract, minus justified deductions for damage beyond normal wear and tear.
• Privacy: the landlord can't enter without your permission.
• IRS deduction: you can deduct a percentage of your rent from your income tax if the contract is registered.

Scams to Avoid

• "I'm abroad, send the deposit and I'll mail the keys." Classic scam.
• Prices far below market for central flats.
• Pressure to pay by Western Union or crypto.
• Fake listings using photos copied from other sites (reverse image search them).
• No contract offered or refusal to register it.

Never transfer money before seeing the flat in person (or by video call with a trusted contact on site) and confirming the landlord is the owner. You can request the property's land registry certificate (certidão permanente) to check ownership.

Renting Before You Arrive

If you need an address for a visa application, options include:

• Medium-term furnished rentals through Uniplaces or Spotahome
• Relocation agents who view flats for you
• Short contracts for a few months, then searching locally once you arrive

Final Thoughts

Renting in Portugal rewards preparation. Get your NIF, have your documents ready, set alerts on Idealista, and be ready to act quickly. Always insist on a written, registered contract, inspect for humidity and heating before you sign, and never send money for a flat you haven't seen. Do that, and finding your new home in Portugal will be far less stressful.
