What are the Costs of Buying a House in Portugal? (International Buyers Guide)

Buying a property in Portugal involves much more than the advertised price tag. Between taxes, fees, and bank commissions, the additional costs can range from 5% to 10% of the property's total price.

These charges include IMT (Transfer Tax), Stamp Duty, notary fees, land registration, insurance, and bank commissions. If you are purchasing with a mortgage, you will also face appraisal and documentation fees.

In this comprehensive guide, we explain all the costs associated with buying a house in Portugal, complete with practical examples, real values, and essential tips for international buyers.

At RE/MAX Cidadela, with over 20 years of experience, 4,800 families assisted, and the best-rated agency on the Cascais Line on Google, we help buyers every day to plan their budget with accuracy and transparency.

Buyer Summary — Buying Costs in Portugal

• Total acquisition costs: typically 5%–10% of the purchase price
• With mortgage: budget 8%–10% (excluding down payment)
• Non-residents: usually 30%–40% down payment + closing costs
• IMT: the largest cost, paid before the deed and never financed
• Stamp Duty: 0.8% on the purchase + 0.6% on the mortgage
• Location matters: Cascais, Lisbon, Oeiras and Sintra have higher absolute costs due to price levels

Main Costs When Buying a House in Portugal

1. IMT (Municipal Property Transfer Tax) — the heaviest cost (and can be €0 for eligible young buyers)
2. Stamp Duty — 0.8% on the purchase and 0.6% on the mortgage amount
3. Deed (Escritura) + Registration — €400 to €1,000
4. Bank Fees (if mortgaged) — ± €1,500 to €3,000
5. Complementary Costs — renovations, condominium fees, insurance, moving

Rules that impact the budget the most:

• Property Location: Zones like Cascais, Oeiras, Lisbon, and Sintra often have higher costs and prices.
• Purpose: HPP (Primary Residence) vs. Investment (higher tax rate).
• Use of Mortgage: Increases initial costs due to bank fees and Stamp Duty on the loan.

Practical Tip: Set aside 8% to 10% of the property value to avoid surprises.

 Which Costs Should I Consider Beyond the Purchase Price?

Beyond the purchase price, there are fiscal, legal, and banking costs. Ignoring them is the most common mistake among buyers.

Main Categories:

• IMT – Municipal Property Transfer Tax
• Stamp Duty
• Deed and Registration
• Bank Commissions and Mortgage Costs
• Complementary Costs (insurance, renovations, services)

How Do Buying Costs in Portugal Compare to Other Countries?

One of the most common questions among international buyers is whether Portugal is an expensive country in terms of acquisition costs. The short answer: Portugal sits in the middle range compared to other European and Anglo-Saxon markets.

Key Insight:
Portugal’s main cost driver is the IMT, which is paid upfront before the deed. Unlike Spain or France, Portugal does not charge notarial fees based on a percentage of the price, and real estate agent commissions are typically paid by the seller — a significant advantage for buyers.

IMT – The "Heavy Weight" Tax (and the Big News for Young Buyers)

The IMT (Municipal Property Transfer Tax) is, historically, the largest single portion of the closing costs. It is paid to the State before the deed and is levied on the greater of two values: the purchase price or the VPT (Taxable Asset Value).

(Note: For international buyers purchasing a secondary home or investment, the standard tables below apply.)

1. IMT Rate Table (General Application: Investment / Second Home)

If you are over 35 or buying for investment, general rates apply. The calculation follows a system of progressive tax brackets. (Note: Bracket values are updated annually in the State Budget. Always consult the table in force for 2025).

General Formula: (Deed Value × Marginal Rate) – Abatement Parcel = IMT Payable

• Primary Residence (HPP): Exempt from IMT if the value is very low (generally below €101,000), increasing progressively thereafter.
• Second Home / Investment: Pays IMT from the very first euro, usually with slightly higher rates.

Expert Tip: IMT must be paid (and the payment slip issued) before the deed. If you are using a mortgage, be aware: banks do not finance the IMT value. This amount must come from your own capital.

The Impact of Location and VPT on Your Wallet

The rule is clear: IMT is levied on the highest value between:

1. The transaction value (Purchase Price).
2. The Taxable Asset Value (VPT).

Stay Alert: Before making an offer, request the Caderneta Predial (Property Tax Booklet) to check the current VPT. At RE/MAX Cidadela, we perform this preliminary analysis to ensure there are no fiscal surprises on the day of closing.

Stamp Duty (Imposto do Selo - IS)

The "little brother" of the IMT, but it also adds to the bill. There are two types of Stamp Duty in a home purchase:

1. Stamp Duty on the Acquisition (0.8%):
   • Levied on the purchase value (or the VPT, whichever is higher).
2. Stamp Duty on the Mortgage (0.6%):
   • Levied on the total amount of the contracted loan.
   • Paid when the money is made available by the bank.

Stay Alert: Stamp Duty is paid at the closing and is not financed by the bank.

Deed, Registration, and Notary Fees

The deed officially finalizes the purchase, and registration inscribes the property in your name.

The final value depends on factors such as the property's price, the number of participants, and the transaction's complexity (e.g., if a mortgage, inheritance, or powers of attorney are involved).

Expert Tip: For transactions involving non-residents, international loans, or Powers of Attorney, oversight by an experienced notary and a specialized lawyer makes a critical difference for legal security.

Banking Commissions and Mortgage Costs

If you use a mortgage, the bank charges specific fees.

Your Rights: Evaluation Deadline and Binding Offer (ESIS)

Before signing, the bank must provide the ESIS (European Standardised Information Sheet), which explains all the conditions and costs of the loan. The client is entitled to a reflection period before accepting.

Expert Tip: The ESIS allows you to compare proposals from different banks. Never accept a rate without seeing this document.

Complementary Costs (The "Hidden" Ones)

After the deed, additional expenses arise that many forget:

Tip: Set aside an extra 2%–3% of the house value for post-purchase adjustments.

What is the Additional Municipal Property Tax (AIMI)?

AIMI (Adicional ao Imposto Municipal sobre Imóveis) is an additional annual tax introduced in 2017.

It applies to owners whose total Taxable Asset Value (VPT)—summing all urban properties—exceeds €600,000. This is an essential consideration for international investors and those buying multiple properties.

How AIMI Works

• It is calculated based on the sum of the VPTs of the owner's urban properties as of January 1st each year.
• Exclusions: Properties classified for commercial, industrial, or service activities are excluded.
• The tax is collected annually in September by the Tax Authority.

AIMI Rates in Force (2025)

Expert Tip (Joint Taxation): For couples with high-value assets, opting for joint taxation (tributação conjunta) can double the exemption limit (to €1.2 million) and significantly reduce the amount payable.

How Location (Municipality) Influences the Annual IMI Rate

The IMI (Imposto Municipal sobre Imóveis) is an annual charge levied on the property's VPT. Although it is not a direct purchase cost, it is a recurring ownership cost and must be factored into financial planning.

Rates are set by each municipality within legal limits (0.3% to 0.45%).

See the common averages in the Lisbon Metropolitan Area, according to the most recent municipal deliberations:

Expert Tip: The IMI is calculated on the VPT, which does not always match the market price. In newly built or rehabilitated properties, the VPT tends to rise after reevaluation, slightly increasing the tax in subsequent years.
