Thinking about purchasing a property in Portugal?

Discover which documents you’ll need to apply for a mortgage as a foreign buyer and how to prepare for a smooth process.

Purchasing property abroad can be complex, especially navigating different legal and financial systems.

This guide will help you understand key steps like obtaining a Portuguese Tax Identification Number (Número de Identificação Fiscal), gathering proof of income, bank statements, and credit history documents. Knowing what lenders expect and how to organize your paperwork will save time and increase your chances of approval. With the right preparation, you can confidently move forward in securing your dream home in Portugal.

Foreign buyers planning to purchase property in Portugal must be equipped with the right documents at each stage of the mortgage process. Knowing precisely and being well-prepared with all required paperwork ensures a smoother journey, avoiding unnecessary delays for successful application.

Step 1: Find Lenders and Get Advice

Start by comparing mortgage options from banks, brokers, or international lenders. Portuguese banks commonly offer tailored solutions for non-residents, and working with a mortgage specialist can help clarify document requirements and provide local advice. There are many banks in Portugal with English-speaking staff who specialize in assisting foreign buyers.

Step 2: Obtain Your Portuguese Tax Identification Number (NIF)

All foreign buyers must obtain a NIF (Número de Identificação Fiscal) is mandatory for any property transaction. Foreigners must apply at a local Tax Authority office with proof of residence and valid ID. If not resident, appoint a Portuguese tax representative to assist the process. The NIF will be required for all legal and financial activities in Portugal

Step 3: Gather Identification and Financial Documents

Banks require a variety of documents to assess eligibility:

- Valid passport or citizen card

- NIF certificate (Portuguese Tax Identification Number)

- Employment contract or income proof (latest pay slips, tax returns)

- Recent bank statements (usually last 3-6 months)

- Credit report from your home country

- Responsibility map (official summary of outstanding debts from the Bank of Portugal)*

- Statement of outstanding debts and central repository of financial responsibilities (if applicable)

OBS: Additional requirements for business owners include company registration, recent tax returns (2-3 years), and financial statements

* The responsibility map (“Mapa de Responsabilidades de Crédito”) is an official summary of all credit obligations in Portugal, required by banks to assess a mortgage application; it can be requested free of charge online at the Bank of Portugal website or at any Bank of Portugal service desk with valid ID and NIF

Step 4: Application Stages and Further Documents

- Pre-approval Stage: Submit all the above personal, financial, and employment documents for the bank’s assessment.

- Property Valuation: The bank arranges an official valuation of your chosen property—you’ll need to provide the property’s preliminary details at this stage.​

- Guarantors: If the bank requires a guarantor (common for some non-resident applicants), they must provide the same set of financial documents as above

Step 5: Essential Property Documents

Before the deed signing, obtain from the seller:

- Property technical sheet (when applicable)

- Land Registry Certificate (Certidão de Teor or Registo Predial)—proof of legal ownership and outstanding debts or encumbrances, dated within 30 days

- Urban property record (Caderneta Predial)

- Occupancy license (or documented exemption)

- Energy certificate

- Property plan (if applicable)

- Statement of no outstanding condominium fees

- Identification documents for all buyers and sellers​

Additionally, if the property is in a zona de pressão urbanística (urban pressure zone) or subject to special legal conditions, the seller must place an "anúncio de Direitos de preferência", a legal notice giving certain parties—like existing tenants or public entities—the right of first refusal on the property purchase. This announcement is submitted online through the Casa Pronta platform with a small fee (€15) and allows a 10-working-day period for these parties to express their interest before the sale proceeds

Step 6: Signing the Deed and Final Steps

Double-check all documentation before signing the deed with the notary, as missing anything can delay the transfer. Funds should be in place and their source clearly documented for anti-money-laundering compliance.​
