How to Rent a Flat in Portugal as an Immigrant: Contracts, Deposits and Your Rights

Last updated: 28 September 2026 · By Haider Shah, accounting technician in Portugal

Housing is one of the hardest parts of moving to Portugal, especially in Lisbon, Porto and the Algarve. Knowing the rules protects you from paying too much, or paying for something that doesn’t exist.

Where to search

• Big portals: Idealista, Imovirtual, Casa Sapo, OLX
• Real estate agencies (imobiliárias). In Portugal, the landlord normally pays the agent
• Community groups, but be extra careful with scams there

What landlords usually ask for

Deposit and advance rent: the limits

• Deposit (caução): by law it cannot be more than 2 months of rent. It must be returned at the end, minus justified damages or debts
• Advance rent: also limited (currently up to 2 months)

The contract

• Always sign a written contract with the landlord’s name and NIF, the rent, duration and deposit
• The landlord must register the contract at Finanças and issue electronic rent receipts (unless legally exempt)
• A registered contract and receipts let you deduct part of the rent in your IRS and prove your address to AIMA and banks

Scams to avoid

• Never pay a deposit for a flat you haven’t seen (in person or on a live video call with someone you can verify)
• Be suspicious of prices far below the market, and of landlords who are “abroad”
• Check who owns the property. A land registry certificate (certidão permanente) shows the owner
• Don’t send copies of your passport to unverified people

Proving your address

Once you live there, update your address at Finanças (for your NIF), with Social Security and at AIMA. If you don’t have a contract in your name, an atestado de residência from the Junta de Freguesia can help.
