Most buyers arrive with a number in mind. The property they end up buying costs more than that number, and the difference is rarely explained clearly before the offer is made.
When buyers ask me what a property in Portugal actually costs, I do not start with the listing price. I start with what they will have to write a check for on the day the deal closes, because that number is meaningfully higher than what the seller is asking.
Portugal is not expensive to buy into compared to other Western European markets. But it does have a layer of acquisition costs that sits on top of the purchase price, and these costs are not optional, not negotiable with the seller, and not something that can be paid in installments. They are due on the day of the deed. Buyers who discover this after making an offer are in a worse negotiating position than buyers who understood it going in.
This is what that layer actually looks like.
The number most buyers start with is not the number that matters
A property listed at EUR 850,000 in Lisbon or Cascais will cost a foreign buyer closer to EUR 910,000 to EUR 930,000 to actually own by the time all legal obligations are fulfilled. The gap between those numbers is made up of taxes and professional fees that are fixed by law or by market practice and that apply regardless of how the negotiation went.
Understanding this before making an offer matters for one practical reason: the acquisition costs cannot be rolled into the property price or deferred. They are paid in addition to the agreed price, at the moment of completion. A buyer who has budgeted EUR 850,000 for a property and discovers the total cost is EUR 920,000 at the point of signing is either forced to renegotiate under pressure or to accept a situation they did not plan for.
In my experience working with buyers across both markets, the buyers who move most efficiently are the ones who arrive with this understanding already in place. The search, the offer, and the negotiation all proceed differently when the full picture is clear from the start.
What the acquisition costs in Portugal are made of
There are two categories of cost that sit above the purchase price: taxes owed to the Portuguese state, and fees paid to the professionals who execute the transaction. Both are real, both are unavoidable, and both are knowable in advance.
The property transfer tax
IMT is the Portuguese property transfer tax. It is calculated on the purchase price or the government’s assessed value of the property, whichever is higher, and it is paid before the deed is signed. For a foreign buyer purchasing an investment property or a second home, the applicable rate is 6% of the total value. For buyers purchasing a primary residence, a sliding scale applies with a partial exemption for values below a certain threshold.
On a property at EUR 850,000 purchased as an investment, the IMT alone comes to EUR 51,000. That figure is fixed. It does not change based on how the negotiation went, how long the property was on the market, or whether the buyer made a strong offer.
Stamp duty
On top of IMT, there is a stamp duty of 0.8% applied to the value of the deed. On the same EUR 850,000 property, that is EUR 6,800. If the purchase is financed with a mortgage, an additional stamp duty of 0.6% applies to the loan amount.
Notary and registration fees
The deed must be signed before a licensed notary, and the transfer must then be registered with the Land Registry. These two steps together typically cost between EUR 500 and EUR 1,500, depending on the complexity of the transaction and the notary chosen.
Legal fees
A buyer-side lawyer handles the verification of the property’s legal status, the review of the purchase contract, and the representation of the buyer’s interests throughout the process. Legal fees in Portugal for this scope of work typically fall between 0.5% and 1.5% of the purchase value, depending on the complexity of the transaction and the firm retained. On a property at EUR 850,000, this represents between EUR 4,250 and EUR 12,750.
Some buyers ask whether legal representation is strictly required. It is not, in the sense that no law mandates it. But the CPCV, the promissory contract that locks both parties into the transaction with a deposit at stake, is a legally binding document. Signing it without someone who has read it on the buyer’s behalf is a different kind of risk.
| Cost component | Rate | On EUR 850,000 purchase |
|---|---|---|
| IMT (investment or second home) | 6% flat | EUR 51,000 |
| Stamp duty on deed | 0.8% | EUR 6,800 |
| Stamp duty on mortgage (if applicable) | 0.6% of loan | Varies by loan amount |
| Notary and Land Registry | Fixed fees | EUR 500 to EUR 1,500 |
| Lawyer (buyer-side) | 0.5% to 1.5% | EUR 4,250 to EUR 12,750 |
| Total overhead (approx.) | 7% to 9% | EUR 62,000 to EUR 72,000 |
What changes if you are buying a primary residence
The 6% IMT rate applies to buyers purchasing a property that will not be their primary residence in Portugal. Buyers who are moving to Portugal and registering the property as their main address are subject to a different, progressive IMT scale that becomes more favorable at lower price points and includes a full exemption for properties below approximately EUR 97,000.
For most international buyers considering Lisbon or Cascais, the relevant scenario is the 6% rate, because the properties they are looking at are typically purchased as second residences or investment assets, and the price points involved place them well above the exemption threshold in any case.
The distinction matters, and it is worth confirming with a Portuguese tax adviser before the acquisition is structured, because declaring the property’s intended use incorrectly creates a compliance problem that is more expensive to resolve than it was to prevent.
What buying a new build from a developer costs differently
Properties purchased directly from developers on the primary market are treated differently for tax purposes. Instead of IMT, the buyer pays VAT (IVA) at a rate of 23% on the construction value, which is typically factored into the listed price. In practice, this means the sticker price already includes the tax, but the overall cost structure differs from a resale transaction.
New builds also carry reduced stamp duty on the deed. The tradeoff is that VAT at 23% on the construction component is a meaningful addition that does not disappear because it is embedded in the price. Buyers comparing a new build at EUR 800,000 to a resale at EUR 800,000 are not comparing equivalent situations, and understanding the difference before making that comparison matters.
Ongoing costs after the purchase
Acquisition costs are a one-time event. What comes after the purchase is a set of recurring obligations that informed buyers account for before they commit.
Annual property tax (IMI)
IMI is Portugal’s annual municipal property tax. The rate varies by municipality and is applied to the property’s fiscal value, which is typically lower than the market value. In Lisbon, the rate is currently 0.3%. In Cascais, it is also within that range. On a property with a fiscal value of EUR 500,000, the annual IMI would be around EUR 1,500.
Condominium fees
Properties in apartment buildings or gated developments carry monthly condominium fees that cover shared maintenance, building insurance, and common area management. These vary significantly depending on the building’s size, age, and amenities. In well-maintained buildings in Lisbon and Cascais, condominium fees for a mid-to-upper segment property typically run between EUR 200 and EUR 600 per month.
Rental income tax for non-residents
Buyers who intend to generate rental income from their Portuguese property are subject to Portuguese income tax on that income. For non-residents, rental income is currently taxed at a flat rate of 25%. This is a gross rate applied to declared rental income, before deductions. The specific deductions available depend on the type of rental agreement and the buyer’s tax situation. A Portuguese accountant is the right person to model this before the acquisition decision is made.
| Ongoing cost | Frequency | Indicative range |
|---|---|---|
| IMI (property tax) | Annual | 0.3% of fiscal value |
| Condominium fees | Monthly | EUR 200 to EUR 600 (mid-upper segment) |
| Building insurance | Annual | EUR 500 to EUR 2,000 depending on value |
| Rental income tax (if applicable) | Annual declaration | 25% flat for non-residents |
| Accountant / fiscal representative | Annual | EUR 500 to EUR 1,500 |
How buyers typically underestimate total cost
The pattern I see most consistently is not that buyers are unaware that acquisition costs exist. Most have heard that Portugal has taxes on property purchases. What they underestimate is the timing and the magnitude together.
The taxes are due on the day of the deed. Not within 30 days. Not in installments. On the day. A buyer who arrives at the notary expecting to pay EUR 850,000 and has not reserved EUR 60,000 to EUR 70,000 separately for taxes and fees is in a difficult position at the worst possible moment.
The second thing buyers underestimate is the cost of not having legal representation during due diligence. A problem discovered after the promissory contract is signed is a problem the buyer now owns financially, because withdrawing from the contract means forfeiting the deposit. Due diligence is not a bureaucratic step. It is the stage where the decision to proceed, or not to proceed, is made with full information.
What the right preparation looks like
Buyers who approach the Portuguese market with a clear cost picture in place from the beginning move differently. They make offers knowing their actual ceiling. They set their promissory deposit knowing they are not overcommitting. They engage their lawyer before identifying a property, not after.
The question I ask buyers before the search begins is not what property they are looking for. It is what their total available capital is, including acquisition costs, and what structure they intend to use for the purchase. Those two answers define the realistic search parameters. Everything after that is more efficient.
If you are at the stage of evaluating whether Portugal makes sense for your situation and want to work through the financial structure of an acquisition before committing to a direction, that conversation is exactly what a private consultation is designed for. The cost picture changes depending on the buyer’s profile, the property’s intended use, and the acquisition structure. Getting that clarity early avoids corrections later.
Frequently asked questions
Can acquisition costs be included in a mortgage in Portugal?
No. Portuguese banks finance the property value only. Taxes, legal fees, and notary costs must be paid separately by the buyer at the moment of the deed.
Do acquisition costs vary by region in Portugal?
IMT and stamp duty are national and apply uniformly. The annual IMI rate varies by municipality but Lisbon and Cascais are within the same range. The more significant variation in total cost comes from property type and intended use.
Is it possible to negotiate the legal fees?
Legal fees are not fixed by law, so there is room for discussion. That said, choosing representation primarily on cost carries real risk. The difference in fee between a thorough and a superficial due diligence is rarely significant relative to the property value.
What happens to the acquisition costs if the deal falls through?
IMT and stamp duty are only triggered at the deed. If the transaction does not close, those taxes are not paid. Legal fees for due diligence are charged for work completed regardless of outcome.
Are there any exemptions or reductions available for foreign buyers?
The IMT primary residence exemption applies to foreign buyers registering the property as their main address in Portugal, but the threshold is well below the price points relevant in Lisbon and Cascais. The prior NHR tax regime was closed in 2024. Current eligibility under the replacement programme should be confirmed with a Portuguese tax adviser.
