CasaporteBuying Property in Portugal as a Foreigner: Proof, Paperwork and Pitfalls
Portugal is open to foreign buyers, and the purchase process itself is fairly straightforward. The friction is earlier: getting agents to take you seriously when your funds sit in a foreign bank and they can't tell you apart from someone browsing on a Sunday. Here's what to expect and how to get the attention — and the viewings.
First, the basics you'll need
A NIF (Portuguese tax number) — required to transact. Non-residents typically appoint a fiscal representative to obtain one.
A Portuguese bank account. Not strictly mandatory to buy, but it makes the deposit, taxes, and ongoing costs far smoother.
A lawyer (advogado) or solicitor. Independent legal representation is strongly advisable — they run the due diligence, check the property's registration and licences, and protect you at the promissory-contract stage.
The purchase steps, briefly
Reservation, then the promissory contract (contrato de promessa de compra e venda, or CPCV), at which point a deposit — often 10% — changes hands and both sides are committed. The deed (escritura) completes the sale before a notary. Budget for IMT (transfer tax), stamp duty, and notary/registration fees on top of the price.
The real problem: being taken seriously
If your money is abroad, agents have no easy way to know you're a genuine buyer, so serious enquiries and casual browsers look identical to them. The result is slow replies and viewings that don't materialise. What changes that is proof — of who you are, and that the funds are real and available — presented before the first viewing.
You do not need to reveal your exact balance to do this. Proving that funds sufficient for the purchase are present, as a band rather than a figure, is enough to move you from 'maybe' to 'show this person the property'.
A clear boundary: this isn't compliance
Proving you're a serious buyer is not the same as anti-money-laundering (AML) or know-your-customer (KYC) compliance. Those are obligations the agency and the notary carry, and they'll run their own checks on source of funds at the appropriate stage. Showing verified identity and available funds up front simply gets you taken seriously — it doesn't replace, and shouldn't be marketed as, regulatory compliance.
Casaporte turns your identity and available funds into a verified buyer profile — confirmed identity and a funds band (never your balance) — that you share with any agency to get taken seriously before the first viewing. It is not AML or KYC compliance. Free.
