Buying Property in Cascais as a Foreigner

Portugal is one of the most foreign-friendly property markets in Europe. In Cascais, international buyers face no restrictions on property ownership. However, there are key steps in the process:

1. Get a NIF (Portuguese Tax Number): Essential for any property transaction.
2. Open a Portuguese bank account: Required for payment and taxes.
3. Secure financing (if needed): Foreigners can apply for a Portuguese mortgage, usually up to 70% of the property value.
4. Promissory Contract (CPCV): Binding contract between buyer and seller, typically with a 10% deposit.
5. Deed (Escritura): Final signature at the notary, transferring ownership.

Obtaining a Portuguese Tax Number (NIF) is a critical first step. Foreigners can apply in person at local tax offices, through a lawyer, or even online with a fiscal representative. This number is required for any property purchase, opening a bank account, and paying taxes.

For those relocating, visas such as the D7 Passive Income Visa or the Digital Nomad Visa provide residency options. These programs are particularly attractive for retirees and remote workers, offering the right to live, work, and travel within the EU. Learn more about how to get a NIF in Portugal.
