Securing a mortgage is often the single largest financial commitment in a lifetime, and in Portugal, it's a crucial step for most home purchases. With various banks offering diverse terms, understanding how to compare proposals effectively is paramount to making an informed decision. The Banco de Portugal (BdP) offers valuable guidance to help consumers navigate this complex landscape.
Simply put, not all mortgage proposals are created equal. Even a seemingly small difference in interest rates or associated costs can translate into thousands of euros saved or spent over the lifetime of a loan. The BdP emphasizes the importance of a thorough comparison to avoid financial surprises and ensure you choose the loan that best fits your needs and financial capacity.

Banco de Portugal's 4 Key Tips for Smart Mortgage Comparison:
The Banco de Portugal recommends a careful review of all documents provided by the bank, especially the European Standardized Information Sheet (ESIS) or Ficha de Informação Normalizada Europeia (FINE), which contains crucial information about each credit proposal. With these in hand, consider these four tips:
Don't Just Look at the Spread: Focus on TAEG and MTIC
While a lower spread might seem attractive, it doesn't necessarily mean the loan is cheaper overall. The BdP advises consumers to prioritize two key indicators that encompass all costs:
TAEG (Taxa Anual Efetiva Global - Annual Percentage Rate of Charge): This measures the total cost of the credit as an annual percentage of the loan amount, including interest, commissions, taxes, mandatory insurances, and other charges. A lower TAEG indicates a less costly proposal for the client, assuming the same loan amount and term.
MTIC (Montante Total Imputado ao Consumidor - Total Amount Charged to the Consumer): This represents the total amount the client will pay back to the bank throughout the entire loan term, combining the loan amount with all associated costs. Again, for proposals with the same amount and term, the one with the lowest MTIC is the most advantageous.
These two indicators provide a more realistic view of the true cost of your mortgage than the spread alone.
Be Wary of Low Spreads Tied to Other Products
Banks may offer reduced spreads if clients agree to purchase other financial products, such as debit or credit cards, or specific insurance. While seemingly beneficial, these associated products can come with their costs. It is crucial to inquire about the impact of these products on the total cost of the loan, both with and without cross-selling. Be aware that if you decide to cancel these products later, the bank may increase the spread as per the contract terms.
Consider the Loan Term Carefully
Longer loan terms often result in lower monthly installments, which can be appealing for managing immediate cash flow. However, the Banco de Portugal cautions that longer terms generally lead to a higher total cost of the credit over time, as more interest accrues. It's important to analyze simulations with different terms to understand the impact on both your monthly payment and the overall amount you'll pay back.
Understand Your Interest Rate Options: Fixed, Variable, or Mixed
The choice of interest rate type significantly impacts your monthly installment.
Fixed Rate: Offers stability with a consistent installment throughout the loan term, shielding you from interest rate fluctuations.
Variable Rate: Tied to an index like Euribor, meaning installments can change periodically, offering potential savings when rates fall but higher payments when they rise.
Mixed Rate: Provides a balance, typically starting with a fixed rate for an initial period (e.g., 5-10 years) followed by a variable rate for the remainder of the term. This can be a popular option for those seeking initial stability.
It's advisable to obtain simulations for each type to choose the one that best aligns with your financial goals and risk tolerance.
