The hidden costs of buying a home in Portugal

The listing says €250,000. That’s the number you repeat to friends, family, your bank manager — it’s the sticker price on the house. But on the day you sign the escritura (deed), the money that leaves your account isn’t €250,000: it’s €286,672.04. The difference, €36,672.04, is the sum of seven line items that nobody usually shows you until you’re sitting at the notary’s table. Anyone who only saves for the deposit finds out the rest too late — usually the week before the deed, doing stressed-out arithmetic.

Deed day

Take the most common example: a €250,000 home, habitação própria e permanente/HPP (primary residence), on the mainland, with a mortgage financing 90% of the value (€225,000) over 30 years, and the deed signed at a Casa Pronta (one-stop deed service) desk. The deposit covers the remaining 10% — €25,000. After that, there are six more line items before you get the keys.

Item	Value
Deposit (10%)	€25,000.00
IMT	€7,042.04
Stamp duty on the purchase (0.8%)	€2,000.00
Stamp duty on the mortgage (0.6%)	€1,350.00
Casa Pronta (deed + registrations, with mortgage)	€700.00
Bank valuation	€280.00
Arrangement fee	€300.00
Total on deed day	€36,672.04

IMT (Imposto Municipal sobre as Transmissões Onerosas de Imóveis — the property transfer tax) at €7,042.04 comes from the official 2026 tables for primary residences — it isn’t a flat percentage, it’s a bracket calculation with a deductible portion (parcela a abater). Imposto do Selo (stamp duty) shows up twice, and it’s easy to mix the two up: €2,000 is 0.8% on the price of the house, and €1,350 is 0.6% on what you borrow from the bank — two different taxes, with different bases, that just happen to both be due before you get the keys.

Casa Pronta costs €700 when a mortgage is involved (€375 if you buy without financing, plus €50 for each extra property on the deed) and covers registering both the purchase and the mortgage at the same desk. The alternative — a traditional notary plus a separate land registry (conservatória) — usually runs between €800 and €1,500, with less predictability on timing. The bank valuation (€280 in this example, typically between €190 and €400) and the arrangement fee (€300, between €250 and €600 depending on the bank) are charged by the bank before it approves the mortgage, without exception.

The under-35 case: the bill drops, but doesn’t disappear

If you’re 35 or under, this is your first home, and you qualify for the regime jovem (under-35 scheme), the numbers change completely. On a €300,000 home financed at 100% — possible, for example, through the garantia pública (state guarantee) — the total on deed day drops to €2,380: €1,800 of stamp duty on the mortgage (0.6% on the €300,000 financed), €280 of valuation, and €300 of arrangement fee. No deposit, no IMT, no stamp duty on the purchase.

Notice what doesn’t change: stamp duty on the mortgage is still there, and in this example it’s €1,800 of the €2,380 — three quarters of the total. The under-35 scheme exempts IMT and stamp duty on the purchase up to €330,539 on the mainland, and it also exempts the emolumentos (registration fees), but it never exempts stamp duty on the financing. It’s the line item most people forget precisely because the others disappear.

The first month

The deed doesn’t close the list. In the first month come the mandatory mortgage insurances — life and multi-risk home insurance — that most banks require as a condition of the loan; the monthly cost varies with age, the outstanding capital and the insurer, and it’s worth comparing quotes instead of accepting the first one. This is where a credit intermediary, registered with the Banco de Portugal (Portugal’s central bank) and paid by the bank (not by you), can help you compare spread and insurance at the same time — without that meaning you should sign up with any particular one.

Then there’s the condominium fee, if the building has one, and the connections nobody thinks to budget for: activating the electricity, water and gas meters, and setting up internet — each supplier charges its own activation fees, which vary by provider and by area. Add to that the move itself, whose cost depends on the volume, the distance, and whether you hire a moving company or do it all yourself.

The first year

IMI (Imposto Municipal sobre Imóveis — the annual municipal property tax) is the cost that surprises first-time buyers most, because it doesn’t arrive with the deed — it arrives the following year, with the first bill landing after you’ve already forgotten to budget for it. It’s charged on the property’s taxable value (VPT), at a rate each municipality sets between 0.3% and 0.45% for urban properties (CIMI — the IMI Code — art. 112) — most municipalities apply the minimum. Since the VPT usually sits well below the market price, the bill is normally lower than intuition suggests — but it exists, and it repeats every year.

That same first year typically brings small adaptation works — a coat of paint, a new lock, an appliance that breaks down — and furniture, even if you reuse some of what you already had. None of these amounts is fixed enough to put a number on; they vary as much with the condition of the house as with the buyer’s taste.

The rule of thumb: add up what you don’t see

The two full examples above give you the extremes. On the €250,000 home without the under-35 scheme, the €36,672.04 on deed day equals 14.7% of the price. On the €300,000 home with the under-35 scheme and 100% financing, the €2,380 equals 0.8%. That’s a difference of almost twenty times — just because of age and the conditions at the time of purchase.

Even in the best-case scenario, that 0.8% only covers deed day; you still need to add insurance, connections, next year’s IMI and the rest of the first year. That’s why our rule of thumb rounds up to a more realistic range: always budget for an extra 4% to 15% of the price of the house, depending on the scheme you buy under and the conditions you negotiate. Anyone who saves only for the deposit usually lands somewhere in the middle of this range without knowing it — and finds out once there’s not much room left to adjust.

Your own numbers

The examples in this guide are fixed points — your house, your scheme and your bank will give you a different number. Before you sign anything, it’s worth adding up your own list line by line, from the deposit to your first IMI bill, instead of holding onto just the listing price.
