The quick check: What you should know in advance

Before you go deeper, you should definitely clarify these points:

👉 Tip: If you clarify these points early on, you often save several weeks in the purchase process.

Preparation & Documents: The Foundation

Before emotions come into play, a clean foundation is needed.

Important documents:

• Valid passport or ID card
• NIF (Número de Identificação Fiscal)
  In the case of bank financing and in some cases in KYC processes:
• Proof of income (last 2 years)
• Proof of equity
• Credit report
• Proof of residence (if not present on identity document)

Timeframe: 1 - 3 weeks

⚠️ Common mistake: Some buyers start with viewings without having conclusively clarified the financing framework and then lose their dream property to better-prepared interested parties.

2. Clarify financing: How much budget is realistic?

Financing is one of the most crucial steps.

Residents: approx. 10 - 20 % equity
Non-residents: approx. 20 - 30 % equity
Additional purchase costs: additional 8 - 10 %

👉 Example: With a purchase price of €500,000, non-residents often need around €125,000 of equity and an additional €40,000 - €50,000 for ancillary purchase costs

⚠️ Common mistake: Many underestimate ancillary costs or calculate too optimistically, which later leads to financing gaps.

3. The viewing: A look behind the scenes

A property in the Algarve quickly convinces with its location and views. However, the details are decisive. Plan enough time per object.

You should pay attention to the following:

• Traces of moisture and mold odor
• Condition of windows, air conditioning and electrics
• Water pressure and hot water system
• Drainage around the house, if relevant

Special case Algarve: The proximity to the sea leads more quickly to moisture effects and also to faster corrosion, especially in metal parts and air conditioning systems.

⚠️ Common mistake: The sea view is convincing, the building fabric is overlooked.

Negotiation, Due Diligence & Preliminary Contract (CPCV): The Crucial Step

a) Once you have found your dream property, the negotiation phase follows. In Portugal, this is controlled by the real estate agents.

b) Legal review by the buyer's lawyer:

• Land Registry Extract (Registo Predial)
• Caderneta Predial (property tax document)
• Building permits

And optional: Technical inspection:

• Expert opinion (approx. 500 - 1,000 €)
• Electrics, statics, water pipes, humidity

⚠️ Common mistake: Extensions without a permit are often overlooked, which can be expensive later.

c) Preliminary Purchase Agreement (CPCV)

The Contrato de Promessa de Compra e Venda (CPCV) is legally binding and should urgently contain all agreements or negotiation results.

Key Points:

Down payment ("Sinal"): usually 10 - 20 %
Withdrawal Buyer → Deposit Lost
Withdrawal from the seller → double repayment

⚠️ Common mistake: Verbal commitments without written fixation. In Portugal, what counts is what is written in the contract.

Be sure to include:

• All financial and non-financial conditions
• Clear deadlines
• Inventory list (if furnished)

Timeframe: 1 - 4 weeks after agreement

5. Notary deed (Escritura): Transfer of ownership

The notary appointment is the official conclusion of the transaction, including final payment, handing over the keys to the buyer and pre-registration for the land register entry.

During the escritura: Payment of real estate transfer tax (IMT) & payment of stamp duty (IS)

Time frame: usually 4 - 12 weeks after CPCV

6. After the purchase: What is often forgotten

After the purchase, the practical phase begins:

• Re-registration of electricity and water
• Registration with the municipality
• Applying for an Internet connection
• Purchase of buildings insurance

⚠️ Common mistake: Failure to re-register with utility providers in good time → unnecessary interruptions
