Once a Portuguese bank approves your finance, what you receive is a formal document: the proposta de crédito habitação, accompanied by the European Standardised Information Sheet known locally as the FINE. For most non-resident buyers in Lagos, this is the first sight of the actual loan terms in writing, and it tends to be longer and more conditional than expected.
Below is a practical walk through what the offer contains in 2026 and the conditions that most often cause problems between issue and signing. Figures reflect general market practice rather than any single product, and a broker will confirm the numbers on your file. For wider context, see our mortgage guide for buying property in Portugal.
Quick Answer
- Non-resident LTV in 2026: typically 60 to 70 per cent, EU-resident euro earners at the upper end
- Stamp duty on the loan: 0.6 per cent for terms of five years or more
- Banco de Portugal DSTI ceiling: 50 per cent of net income
- FINE delivered at least ten days before signing, binding on the bank during that window
1. Loan Amount and Loan-to-Value
The offer opens with the headline numbers: the loan in euros, the property value as accepted by the bank, and the resulting LTV. Most lenders, including Caixa Geral de Depósitos, Millennium BCP, Santander Totta, BPI and Novobanco, are working at 60 to 70 per cent for non-residents in 2026, with EU residents earning in euros at the upper end and buyers from the UK, US, Canada or Australia closer to the lower end.
The figure the bank uses is its own valuation, not the agreed sale price. If the two diverge, the loan is calculated on whichever is lower, which is why the asking price and bank valuation gap matters at this stage.
2. Interest Rate Structure
Variable loans price as a spread above the six-month Euribor, which was running around 2.59 per cent at the start of June 2026. Spreads for non-resident borrowers in 2026 sit roughly in the 0.85 to 1.5 per cent range, with the most competitive lenders quoting from around 0.6 per cent for the strongest profiles.
- Variable rate: six-month Euribor plus a fixed spread, resetting every six months
- Fixed rate: a single rate for an agreed term, often five, ten or up to thirty years
- Mixed rate: fixed for three to five years, then reverting to variable
The offer also quotes a Taxa Anual de Encargos Efectiva Global (TAEG), which folds in spread, mandatory insurances and fees. This is the figure to use when comparing offers from different lenders.
3. Term and the Age Cap
Banks will write mortgages up to thirty years, but the term is also capped by Banco de Portugal macroprudential limits on borrower age at the end of the loan: forty years for borrowers aged thirty or under, thirty-seven for those aged thirty-one to thirty-five, and thirty-five for those over thirty-five. For a non-resident buyer in their mid fifties, that brings the maximum term down to around twenty to twenty-five years.
4. The DSTI Ratio and Income Test
Behind the offer is the debt service to income calculation. Banco de Portugal sets a ceiling of 50 per cent of net monthly income across all credit commitments, and Portuguese banks prefer to see non-resident files closer to 30 to 35 per cent. The offer does not usually publish the DSTI figure, but it lists the income and existing commitments the bank has accepted, and that is the line to check first.
Common reasons the income line ends up lower than expected include foreign rental income only being partially recognised, bonus or commission income being averaged across three years, and self-employed income being taken net of the most recent year’s tax.
5. Required Documentation
By the time the offer is in your hands, the bank already holds a documentation file. If anything in that file is out of date by the time you sign, the offer can be withdrawn. The typical non-resident pack is:
- Passport, NIF and proof of residential address in your home country
- The last three years of tax returns or local equivalent
- Six months of personal bank statements, often more for self-employed applicants
- Recent payslips or audited accounts and a credit report from your home country
- Property documentation: caderneta predial, certidão permanente and the bank’s valuation report
6. Stamp Duty and Costs on the Offer
Imposto do Selo on the mortgage is 0.6 per cent of the loan amount for terms of five years or more, and 0.5 per cent for terms between one and five years; this sits separate from the stamp duty on the property deed. The offer also lists valuation, dossier and registration fees, typically in the 600 to 1,200 euro range, plus the life and buildings insurances the bank requires.
7. Conditions That Make the Offer Binding
The FINE is binding on the bank for the period stated, with at least ten days before signing as a regulatory minimum. The lender is committed to the conditions in writing during that window; you are not, and you remain free to walk away. What can release the bank from its commitment is a change on your side.
- A material change in income, employment or debt position
- New credit applications appearing on your central credit file
- Failure to take out the life or buildings insurance the offer requires
- The valuation report being revised after a further inspection
An offer in principle, sometimes called pré-aprovação, is not the same document. It is a soft indication based on borrower profile alone, before the property valuation and full underwriting. Sellers in Lagos now often ask to see the actual FINE rather than a pre-approval letter.
8. Why Offers Are Pulled Late
Late withdrawals usually come back to one of three causes. The first is a documentation gap that the bank only spots on the final compliance check, such as a missing certified translation or an expired payslip. The second is a fresh credit enquiry between offer and signing, which moves the DSTI ratio. The third is a property issue from the valuation revisit, often a discrepancy between the marketed area and the caderneta predial. None are insurmountable, but they tend to surface in the last fortnight before the escritura.
Summary
A Portuguese mortgage offer for a non-resident in 2026 is a detailed document setting LTV, rate structure and the conditions under which the lender stays committed. Reading it carefully before you countersign avoids most of the late-stage problems we see in the Lagos market. The Banco de Portugal macroprudential limits and specialist commentary from non-resident brokers such as Inspired Mortgages are good places to cross-check anything unusual, and the Portuguese Tax Authority Stamp Duty schedule confirms the rates.
At B&P Real Estate we do not advise on lending terms ourselves, but our sister company Inspired Mortgages specialises in non-resident mortgage files for buyers in the western Algarve and works through this exact document and its conditions every week. If you are planning a purchase in Lagos and want an introduction, we are happy to make one.
