Step-by-Step Guide to Securing a Mortgage When Purchasing Algarve Real Estate

Navigating the mortgage process in Portugal is essential for anyone interested in houses for sale, particularly in popular regions like Lagos and the wider Algarve. With the increase in demand for homes, understanding each stage can help you secure the best financing and streamline your property purchase.

Recent data from Portugal’s National Statistics Institute (INE) shows that mortgage lending reached record highs in early 2025, reflecting the sustained interest in real estate. With this level of competition, being fully prepared is critical for buyers.

This guide outlines each step, helping you make expert, informed decisions when financing your Lagos or any Western Algarve property.

Step 1: Assess Your Financial Capacity

Before applying for a mortgage, carefully calculate how much you can realistically borrow and repay.

Key benchmarks in Portugal (2025):

- Residents: Eligible for up to 80–90% Loan-to-Value (LTV)
- Non-residents: Typically offered 60–70% LTV
- Mortgage terms: Range from 5 to 40 years
- Eligibility factors: Age, income, credit profile

Portuguese banks strictly monitor your Debt-to-Income (DTI) ratio. Monthly debt repayments should not exceed 30–35% of your net monthly income.

Given the competitive nature of the Algarve real estate market, having your finances in order before starting your search for homes ensures a more efficient buying process.

Step 2: Select the Right Lender

You can apply directly through Portuguese banks or work with a specialised mortgage advisor. If you are unfamiliar with local systems, engaging reputable real estate agents in Portugal, like B&P Real Estate, can connect you with reputable financial service providers.

It is recommended to compare:

- Lending conditions for residents and non-residents
- Fixed versus variable interest rate options
- Associated fees and charges

Step 3: Prepare the Necessary Documentation

To apply for a mortgage in Portugal, you will need the following:

- Valid passport or EU identification
- Portuguese tax identification number (NIF)
- Proof of income (recent payslips, employment contracts, pensions)
- Recent bank statements
- Credit report (especially relevant for non-residents)
- Details of existing assets and liabilities
- Signed promissory contract (Contrato de Promessa de Compra e Venda)

Tip: Official translations may be required for any documents not originally in Portuguese.

Step 4: Obtain Mortgage Pre-Approval

A mortgage pre-approval (pré-aprovação) offers several advantages:

- Focuses your search for property within a budget
- Demonstrates seriousness to sellers
- Enables faster closing once you find a home

Pre-approval typically involves a soft credit check and preliminary income assessment.

Step 5: Bank-Led Property Valuation

After choosing a property, the bank will conduct an official valuation (avaliação bancária) to determine its fair market value. The mortgage amount is based on this valuation, not necessarily the negotiated purchase price.

In Lagos, where property values have risen steadily year-on-year, valuations play a critical role in determining final mortgage conditions (Source).

Step 6: Receive Final Mortgage Approval and Offer

Upon successful document verification and property valuation, the lender will issue a final mortgage offer detailing:

- Type of interest rate (fixed or variable)
- Mortgage term
- Monthly repayment amount
- Associated terms, including early repayment penalties if applicable

Note: Most Portuguese mortgages remain variable-rate and are indexed to the 12-month Euribor.

Step 7: Sign the Property and Mortgage Deeds

The purchase process concludes by signing two official documents before a public notary:

- Escritura Pública de Compra e Venda (Deed of Purchase and Sale)
- Escritura de Hipoteca (Mortgage Deed)

Following this, both the property and mortgage are legally registered under your name.
