For a growing number of Polish investors, purchasing a premium property in Portugal is no longer simply a decision to relocate. It is becoming part of a broader wealth strategy — an apartment in Lisbon, a villa in Cascais, a residence in the Algarve or a second home in Comporta can combine private use with investment potential and capital protection within a stable European market.
Polish citizenship or foreign tax residency does not prevent a buyer from obtaining financing from a Portuguese bank. It does, however, require careful preparation. Local institutions assess not only the value of the property itself, but the client’s entire financial profile: the sources and currency of income, liquidity, the borrower’s age, existing liabilities and the way their wealth is managed. For nearly three decades, Partners International has supported its clients precisely at this stage — where the decision to purchase meets the realities of the Portuguese banking sector.
For affluent clients, the broader relationship with the bank may be just as important as creditworthiness itself. This may include transferring part of their assets, providing additional collateral or using private banking services. The final financing terms, however, always remain subject to an individual assessment.
How much equity is required when purchasing a property in Portugal
When purchasing a property intended as the buyer’s own permanent residence, Portuguese regulations allow financing of up to 90% of the property value. In the case of a second home, holiday property, rental property or investment purchase, the maximum financing level is generally 80%.
This does not mean, however, that every foreign client will receive financing equal to the maximum permitted limit. In practice, banks tend to take a more conservative approach towards non-residents, typically offering financing of approximately 60–75% of the property value. The final LTV, or loan-to-value ratio, depends on the strength of the client’s profile, the type of property, the source of income and the policy of the particular bank.
The method used to determine the financing base is crucial. The bank adopts the lower of the following two values:
- the purchase price stated in the agreement,
- the property value determined by an independent valuer.
If a property is purchased for EUR 2 million but the bank valuation amounts to EUR 1.8 million, the financing will be calculated on the basis of EUR 1.8 million. At an LTV of 70%, this means a maximum loan amount of EUR 1.26 million. A well-prepared investor therefore secures not only the required equity contribution, but also a reserve to cover any difference between the transaction price and the bank valuation.
Costs not covered by the mortgage
Purchasing a property in Portugal requires capital beyond the equity contribution itself. As a rule, Portuguese banks do not finance taxes or most of the costs associated with completing the transaction.
The buyer may be required to cover, among other things:
- IMT property transfer tax. The new tax change introduced in 2026 should also be taken into account, imposing a 7.5% property transfer tax on foreign buyers,
- stamp duty on the purchase,
- stamp duty related to the mortgage,
- the cost of the bank valuation,
- fees for the assessment and arrangement of financing,
- legal fees,
- notarial and registration costs,
- property insurance,
- life insurance required by the bank.
For premium properties, the budget should include a safety margin significantly greater than the equity contribution alone would suggest — as the equity contribution represents only part of the total capital commitment.
Financing of up to 100% for buyers under the age of 35
Under certain circumstances, the Portuguese public guarantee scheme may make it possible to obtain financing of up to 100% of the purchase value. However, this solution is not intended for the typical foreign investor or for most transactions in the premium property market.
The scheme applies to individuals aged between 18 and 35 who are Portuguese tax residents, are purchasing their first residential property and intend to use it as their own permanent home. Additional conditions include, among others, not owning any other residential property, meeting specified income criteria and purchasing a property valued at no more than EUR 450,000.
From the perspective of a Polish client seeking a second home, an investment apartment or a luxury villa, the scheme therefore has limited relevance.
How a Portuguese bank assesses creditworthiness
The fundamental element of the assessment is the relationship between all of the client’s monthly financial obligations and their net income — the DSTI, or debt service-to-income ratio. The bank takes into account the instalment of the proposed Portuguese mortgage, as well as the client’s other financial commitments, including:
- mortgages in Poland,
- lease agreements,
- consumer loans,
- credit card limits,
- guarantees,
- maintenance payments,
- other regular liabilities.
As a rule, the total amount of monthly repayments should not exceed 50% of the client’s monthly net income. For clients earning income outside Portugal, the bank may apply more conservative assumptions. In the case of variable or mixed interest rates, the bank will also assess a scenario involving an increase in interest rates. Creditworthiness may therefore be calculated using a repayment amount higher than the one applicable at the time the application is submitted.
The importance of the buyer’s income currency
Most mortgages in Portugal are granted in euros. For a client earning income in Polish zloty, this creates exposure to currency risk arising from fluctuations in the EUR/PLN exchange rate. The bank may therefore apply an additional buffer, reduce the amount of income accepted for assessment purposes or offer a lower financing level.
The situation is usually more straightforward for clients whose salary, dividends or business income are denominated in euros. The type of income is also important — an employed client is assessed differently from an entrepreneur, company shareholder, management board member or investor whose income derives from dividends and rental revenue. In the case of business owners, the bank may require not only personal tax returns, but also company financial statements, information on the ownership structure and confirmation of salaries or dividends paid.
The borrower’s age and the maximum financing term
The duration of the mortgage is directly linked to the client’s age and the bank’s internal policy. The maximum financing term may be:
- up to 40 years for clients under the age of 30,
- up to 37 years for clients aged between 30 and 35,
- up to 35 years for clients over the age of 35.
In practice, foreign buyers are most commonly offered mortgage terms of between 25 and 30 years. Many banks also apply a rule requiring the mortgage to be repaid in full before the oldest borrower reaches the age of 75. In the case of a joint application, it is therefore the age of the older applicant that may determine the maximum repayment schedule.
Fixed, variable and mixed interest rates
The Portuguese market offers three main interest-rate models.
Fixed interest rate. The interest rate remains unchanged for the period specified in the agreement, providing predictable repayments and limiting the risk associated with rising interest rates. For an investor who values cost stability and intends to hold the property over the long term, this may be a particularly comfortable model.
Variable interest rate. This usually consists of the Euribor rate plus the bank’s margin and is revised according to the cycle specified in the agreement — typically every 3, 6 or 12 months. A fall in Euribor reduces the repayment amount, while an increase translates into higher debt-servicing costs.
Mixed interest rate. This combines both solutions: a fixed rate applies during the first few years, after which the mortgage switches to a variable rate. It provides initial stability while retaining the possibility of benefiting from future market changes.
How to compare bank offers
When selecting financing, the assessment should not focus solely on the bank’s margin or the monthly repayment amount. The most important parameters include:
- TAN, the nominal annual interest rate,
- TAEG, the annual percentage rate of charge,
- MTIC, the total amount payable over the entire mortgage term,
- bank fees,
- insurance costs,
- early repayment terms,
These figures can be found in the FINE document, the European Standardised Information Sheet for mortgage loans. It is the comparison of FINE documents, rather than advertised headline terms alone, that makes it possible to assess the true cost of financing properly.
Early repayment of a mortgage
An investor who plans to sell the property after several years or repay the mortgage ahead of schedule should pay particular attention to the fees associated with partial or full early repayment. The standard maximum limits are up to 0.5% of the repaid principal for variable-rate mortgages and up to 2% for fixed-rate mortgages. These terms may be highly relevant in the case of a shorter investment horizon and should be analysed just as carefully as the interest rate or monthly repayment amount.
Documents required for a mortgage in Portugal
The scope of documentation depends on the bank, the client’s profile and the source of income. A Polish buyer should, however, be prepared to provide primarily:
- a national identity card or passport,
- a Portuguese NIF tax identification number,
- proof of residential address,
- information on tax residency,
- documents confirming employment or business activity,
- bank statements covering the previous three to six months,
- confirmation of salary payments or regular income,
- tax returns for the previous one or two years,
- a statement of current loans and liabilities,
- a BIK credit report, if requested by the bank,
- confirmation of the source of the equity contribution,
- proof of sufficient funds to cover taxes and transaction costs.
Business owners and company shareholders may additionally be asked to provide financial statements, corporate registration documents, information on the ownership structure, company tax returns and confirmation of dividend payments. Documents issued in Poland may require translation into Portuguese or English. In some cases, the bank may require a sworn translation or additional certification.
How the mortgage process works
Initial financial assessment. Before beginning the property search, it is advisable to determine the realistic level of financing, the required equity contribution and the total amount of capital needed to complete the transaction.
Preliminary decision. Based on information concerning income, liabilities and assets, the bank presents indicative financing terms. This decision does not yet constitute a final commitment on the part of the bank.
Property selection and legal due diligence. Once a suitable property has been identified, its legal status, registry entries, permits, consistency of the stated floor area with the documentation and any existing mortgage encumbrances should be verified. In the premium segment, the legality of extensions, swimming pools, ancillary buildings, terraces or alterations made by previous owners can be the source of the most serious complications.
CPCV preliminary purchase agreement. The Portuguese preliminary agreement, the Contrato-Promessa de Compra e Venda, sets out the principal terms of the transaction and usually involves the payment of a deposit. If the purchase is conditional upon obtaining financing, the document should include an appropriate financing clause. Without such a clause, the buyer may risk losing the deposit if the mortgage application is declined.
Bank valuation. The bank commissions an independent valuation of the property, the outcome of which directly affects the maximum mortgage amount.
Final decision. Once the assessment has been completed, the client receives the final financing terms together with the FINE document. At this stage, the costs, insurance requirements, repayment amount and early repayment conditions should be reviewed in detail.
Completion of the purchase. The final stage involves signing the deed of transfer, establishing the mortgage, settling the applicable taxes and registering the ownership in the Portuguese property register.
How long does the financing process take
With complete documentation and a transparent income structure, the process may be completed within several weeks. More complex cases may require two or three months. The timeline is influenced by, among other things, the completeness of the documentation, the need for translations, the form of employment, the number of companies and income sources, the currency of income, the value and nature of the property, the valuation result, any legal irregularities and the pace of work of both the bank and the valuer.
When purchasing a premium property, an excessively short completion period specified in the preliminary agreement can turn a calm process into a race against time. A properly planned timetable allows sufficient room for thorough analysis and protects the buyer against decisions made under pressure.
A mortgage as a wealth-management tool
For affluent clients, financing a purchase is often not driven by a lack of capital. It may be a deliberate choice that allows them to preserve liquidity, avoid closing other investments and spread the commitment of funds over time.
A mortgage can therefore form part of a broader wealth strategy. This does not, however, mean that the highest available financing level will always be the most rational solution. A proper assessment usually takes into account:
- the total interest cost,
- the risk of changes in Euribor,
- currency risk,
- insurance costs,
- property maintenance costs,
- the intended holding period,
- potential rental income,
- taxes associated with the purchase, ownership and sale,
- succession planning,
- the future investment exit strategy.
In the premium segment, financing should be aligned with the entire strategy for purchasing, using, renting, transferring and ultimately selling the property.
How to prepare properly for the purchase
Will the property serve as a second home, a permanent residence or an investment? This determines the maximum LTV — up to 90% for a permanent residence and up to 80% for a second home or investment purchase — and consequently shapes the entire transaction budget.
What proportion of the purchase price should be financed with a mortgage? This should be established before the property search begins, as it determines both the required equity contribution and the reserve needed to cover any difference between the purchase price and the bank valuation.
In which currency is the income earned? Income in euros simplifies the bank’s assessment. Income in Polish zloty creates the need for an additional currency buffer and usually results in a lower financing level.
Which liabilities will the bank include in its assessment? In addition to the repayment of the Portuguese mortgage, the bank adds together all of the client’s other liabilities — including those incurred in Poland — as part of the DSTI calculation.
How much capital can be allocated to the equity contribution, taxes and additional costs? Transaction costs — including taxes, notarial fees, commissions and insurance — may amount to more than ten percent of the purchase price and are not covered by the mortgage.
Should the purchase be made privately or through a company? The ownership structure affects the required documentation, the way income is assessed and, indirectly, the future tax and succession strategy.
How long is the property expected to remain in the portfolio? A shorter investment horizon makes early repayment conditions particularly important, while a longer horizon places greater emphasis on the choice between fixed, variable and mixed interest rates.
Should the preliminary agreement include a clause making the purchase conditional upon obtaining financing? For a mortgage-financed purchase, such a clause protects the deposit if the bank declines the application. Omitting it can be one of the most costly oversights in the entire process.
The better the transaction structure is prepared, the lower the risk of delays, unforeseen costs and decisions made under time pressure.
