Non-resident mortgage requirements in Spain

NIE: the mandatory first step

The Numero de Identidad de Extranjero (NIE) is essential for any financial, tax or property transaction in Spain. Without it, you cannot open a bank account, sign a mortgage or buy a property.

You can apply at the Spanish consulate in your country of residence (recommended, faster) or in person at an immigration office in Spain. In both cases you will need: a valid passport, proof of purpose (letter of intent to purchase or arras contract) and form EX-15.

The timeline varies depending on demand: between 2 and 6 weeks. It is best to start as early as possible, as nothing else can progress without the NIE.

Financial documentation: what the bank needs to see

The bank wants to answer three questions: how much do you earn? Is your employment stable? Where does the deposit money come from? Your documentation must answer all three clearly.

Sworn translations and apostille

All documents not in Spanish must be submitted with a sworn translation (an official translation by a translator authorised by the Spanish Ministry of Foreign Affairs).

Additionally, if your country is a signatory to the Hague Convention (most are), public documents need the Hague Apostille to be valid in Spain.

Indicative cost: between 50 and 200 EUR per translated document. Budget 400-800 EUR for the full set. Timeline: 1-2 weeks per document.

Opening a bank account in Spain

You will need an account at a Spanish bank to set up the mortgage direct debit, receive transfers, and pay purchase costs. To open one you need: NIE, passport and a certificate of non-fiscal-residence.

Not all banks allow remote account opening. Those with the most experience with non-residents (Santander, CaixaBank, Sabadell) tend to have smoother processes. It is advisable to open the account at the bank where you will apply for the mortgage.

After opening, you will need to transfer the deposit and cost funds. The bank will verify the origin of these transfers as part of anti-money-laundering compliance.
