Housing is the biggest single spend of your whole move, and the easiest place to get caught out, whether you are renting your first flat or buying a home. The Portuguese system protects you well if you use it, and leaves you exposed if you do not. Here is what makes a rental safe, how to check the people you are dealing with, and what an independent lawyer does that nobody else will.

The lease that actually counts

A long-term lease in Portugal has to be registered with the tax authority. Your landlord must declare it to Finanças, and a registered lease is what AIMA, banks and utility companies accept as proof of address. An unregistered lease leaves your landlord non-compliant and you without the proof you need for residency and admin. Always insist the lease is registered, and get the confirmation.

On deposits, expect to put down the first month plus a deposit, often two to three months in total. Be wary of anyone demanding far more up front.

Check the agent before you trust them

Estate agents in Portugal must hold an AMI licence, issued by IMPIC, the public construction and property regulator. You can check any agent’s AMI number free on the IMPIC website before you hand over a cent or sign anything. An unlicensed agent gives you no consumer protection. This thirty-second check filters out a lot of trouble.

What an independent lawyer does when you buy

If you are buying, hire your own lawyer, not the seller’s and not the agent’s. Their job is to confirm you are buying what you think you are, free of nasty surprises. They check:

• The land registry certificate (certidão permanente), confirming ownership and revealing any mortgages, seizures or charges on the property.
• The tax register (caderneta predial), confirming the description and the registered owner.
• The habitation licence and the energy certificate.
• Any outstanding debts, such as condominium fees or property tax.

They do all of this before you sign the promissory contract and pay a deposit, which is the point of no easy return.

Mortgages for new and non-residents

If you are borrowing, expect non-residents to be offered a lower loan-to-value than residents, often around 70% of the price or valuation against up to 90% for residents on a main home. Portuguese lending rules also apply a stress test and a cap on how much of your income can go to debt. A mortgage broker who works with international buyers can save you time and find a lender that fits your profile. Budget for roughly 7 to 8% in purchase costs on top of the price.

If you let a property: F or B matters

If you end up letting a property out, how it is taxed depends on what you are doing. Long-term residential rent is taxed as property income (Category F), where longer leases attract meaningful rate reductions. Short-term and holiday letting (Alojamento Local) is taxed as business income (Category B), with its own registration and rules. Getting the category right, with an accountant, changes your tax bill.

Frequently asked questions

Why does my lease have to be registered?

Because a registered lease is your accepted proof of address for residency, banking and utilities, and it keeps your landlord compliant. Without it, you may struggle with AIMA and other admin.

How do I know an estate agent is legitimate?

Check their AMI licence number on the IMPIC website. Licensed agents are listed; unlicensed ones offer you no protection.

Can a non-resident get a Portuguese mortgage?

Yes, but usually at a lower loan-to-value than residents, around 70%, subject to affordability and stress-test rules. Budget around a 30% deposit plus costs.
