A practical method for comparing mortgage offers on the same assumptions, identifying linked costs and stress-testing the payment.
Key takeaways
- Compare the same amount and term.
- Use APR and total cost, not only spread or payment.
- Stress-test the full household budget.
A lower initial payment does not necessarily mean a cheaper or more suitable loan. Ask every lender to simulate the same amount, term, purpose and borrower profile, then compare the personalised European Standardised Information Sheet, known in Portugal as the FINE.
The Bank of Portugal explains the pre-contractual information process. Record the nominal rate, APR/TAEG, total amount payable/MTIC, initial payment, fees, insurance, optional linked products and the conditions for retaining any discount.
Fixed, variable and mixed rates
The Bank of Portugal describes fixed, variable and mixed mortgage rates. A fixed period improves predictability; a variable rate normally combines an index such as Euribor with a spread; a mixed rate changes from a fixed phase to a variable phase. Note the length and rules of every phase.
A reliable comparison process
- Use the same loan amount and term in every offer.
- Compare TAEG/APR and MTIC, not only the payment or spread.
- List one-off costs, insurance and recurring product fees.
- Check what happens if a linked product is cancelled.
- Run a household stress test with a higher payment plus insurance, property tax, condominium costs, maintenance and an emergency reserve.
- Verify that the approved FINE still matches the scenario you selected before signing.

No rate type is universally best. The appropriate choice depends on income stability, monthly headroom, expected time in the property and tolerance for payment changes. This is general information, not personalised financial advice.
