Banco de Portugal mortgage guide

TAN is the annual nominal interest rate, excluding fees and insurance. LTV is the loan divided by the property price. This model uses a 90% financing limit for a main home and 80% for other use. DSTI compares stressed loan payments with net income; the model ceiling is 45%.

The loan payment consists of principal repayment and interest; insurance is separate. A fixed rate stays the same for the whole term. The variable-rate estimate holds the entered rate constant. A mixed rate starts fixed; after that period the remaining balance is repaid at an assumed 3.5%. Future rates are unknown.

The deposit is the part of the price you pay yourself. Cash needed also includes IMT, purchase stamp duty at 0.8%, loan stamp duty at 0.6%, and a fixed €1,500 allowance for bank, valuation and legal fees. These expenses are additional to the deposit.

The model uses standard mainland Portugal 2026 IMT rates and a 7.5% nonresident assumption, without youth or other exemptions. Purchase price, taxable value and valuation are assumed equal. Life and home insurance are rough age, loan and price estimates; their cost stays constant in the projection. Confirm actual costs and tax treatment separately.

Income mode fits the highest ordinary payment plus insurance within 35% of income and the stressed loan payment within 45%. Other debts are fixed at zero. Payment mode uses the loan payment alone and budgets for the higher payment across both mixed-rate periods. Taxes and deposit are extra.

The model adds 0.5 percentage points for terms up to 5 years, 1 point up to 10 years and 1.5 points beyond that. A full-term fixed rate has no shock. The model accepts ages 18–70, terms 5–40 years, a 40-year cap up to age 35 and 35 years above that, and a conservative repayment-by-75 assumption.

This is a qualitative planning scale, not a bank approval probability. Exceeding the financing limit or 45% stressed debt burden gives a low outlook. A burden up to 35% and financing up to 80% gives a high outlook; other valid cases are medium. Credit history, documents and bank policies are excluded.

The monthly total is principal and interest plus estimated life and home insurance. The cash needed at purchase is the down payment, IMT, stamp duties and a fixed €1,500 allowance. This allowance and the insurance estimate are planning assumptions; they do not include ongoing costs such as IMI, condominium fees or maintenance.
