Getting a Mortgage in Portugal:
What International Buyers Need to Know
Mortgage planning should begin before a serious property search. A lender assesses the borrower, the source and stability of income, existing debt, age, residency and the property itself. The result can be very different from an online calculator.
- Start at least four months before you expect to be ready for completion. This is our practical planning experience, not a legal or bank deadline.
- A pre-assessment is not final approval.
- Loan-to-Value (LTV) limits under Banco de Portugal’s framework are maximum limits, not guaranteed offers.
- From 1 August 2026, the general recommended Debt Service-to-Income (DSTI) limit is 45%; the assessment includes existing debts as well as the proposed mortgage.
- Ask what income the lender will actually recognise, especially for self-employment, dividends, investments, bonuses and buy-to-let rent.
What the rules say, and what lenders do
Loan-to-Value
Banco de Portugal’s framework allows an LTV of up to 90% for a borrower’s own permanent home and generally up to 80% for other purposes. LTV is measured against the lower of purchase price and valuation. A lender can offer less, and international or non-resident borrowers often encounter more conservative practice.
For early planning, many international buyers are safer modelling around 60% to 70% finance until a lender or broker confirms otherwise. This is an experience-based planning range, not a promise or universal market rule.
Income recognition
Banks do not treat every euro of income in the same way. Salary is usually easier to evidence. Self-employed earnings may require a longer history. Bonuses, dividends, company income, investments and rent can be averaged, discounted, capped or excluded, depending on the lender and the evidence.
Buy-to-let income needs particular care. A bank may recognise only part of existing rental income, may want leases and tax returns, and may not include projected rent from the property being bought. Ask for the lender’s treatment in writing before building the budget around it.
Affordability
The Debt Service-to-Income ratio (DSTI) compares the total monthly payments on all of the applicant’s loans, including the proposed mortgage, with their net monthly income.
For affordability assessments carried out from 1 August 2026, Banco de Portugal’s general recommended DSTI limit is 45%. The calculation also considers the effect of potential interest-rate increases and, where applicable, changes in income. Limited exceptions exist at lender-portfolio level, but buyers should not assume that borrowing above 45% will be available.
This is a maximum recommended limit under Banco de Portugal’s framework, not an indication of what a particular bank will approve. Lenders can apply lower limits and will also consider living costs, dependants, existing debts, income stability, age, residency, currency exposure and their own internal risk policies.
Mortgage term
For affordability assessments carried out from 1 August 2026, Banco de Portugal’s maximum recommended mortgage term depends on the age of the oldest applicant:
- Applicants aged 35 or under, up to 40 years.
- Applicants over 35, up to 35 years.
These are maximum terms under Banco de Portugal’s recommendation, not guaranteed offers. Banks can impose shorter terms according to the applicant’s age at final repayment, income, residency, property use and internal lending policy.
Non-resident mortgages are commonly limited to 25 or 30 years, depending on the lender. A 30-year term is therefore a common market maximum for non-residents, rather than a separate universal Banco de Portugal rule.
A shorter term increases the monthly repayment and may reduce the amount a buyer can borrow. Confirm the term a lender will actually offer before relying on an affordability calculation or making a finance-dependent commitment.
The valuation and final approval
The bank approves both the borrower and the security. If the valuation is below the purchase price, the buyer will need to cover the difference. Final approval normally remains subject to full documentation, valuation and property checks even after an encouraging early assessment.
What to compare
Do not compare the spread alone. Review the interest-rate basis, total instalment, insurance, fees, early-repayment conditions and the Taxa Anual de Encargos Efetiva Global (TAEG), the effective annual cost measure shown in Portuguese lending documents.
Allow at least four months.
Four months from starting the mortgage process to being ready for completion is our practical minimum for an efficient international case. It assumes documents are complete and there are no complications. Start earlier if income is unusual, documents cross several countries or timing is important.
Risks and things to remember
- A pre-assessment can change after full underwriting or valuation.
- Do not sign an unconditional CPCV because the first response from a bank was positive.
- Confirm which income is recognised, not only your gross annual income.
- Test the cash requirement if the valuation is lower than the agreed price.
- Ask how long the offer remains valid and what must still happen before funds can be released.
