Portugal Real Estate Scams: What Foreign Buyers Need to Know in 2026

Portugal's property market has attracted record foreign investment in recent years, and where money flows, fraud follows. Portuguese authorities recorded over 1,500 cases of fake property ownership claims in 2024 alone, many targeting foreign buyers unfamiliar with local systems. Fake rental schemes increased 25% year-on-year, and Golden Visa scam operations continue to operate openly despite the 2023 reform.

Here is what you need to watch for, and how to protect yourself.

Renovation Scams in Lisbon and Porto

The renovation market in Lisbon's Alfama, Mouraria, and Graça neighborhoods, and Porto's Baixa and Cedofeita districts, is a minefield for foreign buyers. The typical scheme works like this:

A buyer purchases a run-down property for €150,000 to €250,000 and hires a contractor who quotes €80,000 for a full renovation. The contractor shows impressive before-and-after photos from previous projects. Work begins with a 30-50% upfront deposit. Then the timeline slips. The contractor disappears for weeks. Materials are substandard. Costs escalate with "unforeseen structural issues." The final result bears little resemblance to what was promised, if the project is completed at all.

Red flags to watch for:

The contractor has no alvará de construção (construction license) registered with IMPIC. The "before and after" photos cannot be verified with a site visit or independent reference. The quote lacks a detailed breakdown of materials, labor, and timeline. The contract has no penalty clauses for delays. The contractor demands more than 20% upfront before any work begins.

How to protect yourself:

Verify the contractor's license on the IMPIC portal (Instituto dos Mercados Públicos, do Imobiliário e da Construção). Any legitimate construction company operating in Portugal must be registered here. Insist on a fixed-price contract (contrato de empreitada) with milestone-based payments. Hire an independent fiscal (project supervisor) to inspect work at each stage. Budget 15-20% above the quoted price for genuine contingencies, but never accept open-ended cost increases without independent verification.

Off-Plan Deposit Fraud in the Algarve

The Algarve's development boom has attracted both legitimate developers and opportunistic fraudsters. The typical off-plan scam involves a company marketing luxury apartments or villas at pre-construction prices. Glossy renders show infinity pools and ocean views. The company collects reservation deposits of €10,000 to €50,000. Construction never starts, or stalls after foundations are laid. The company enters insolvency and buyers lose their deposits.

Portuguese law requires developers selling off-plan to provide a bank guarantee or insurance for deposits under Decree-Law 67/2003 and the consumer protection framework. In practice, enforcement is inconsistent and many buyers sign contracts that waive or obscure these protections.

Before paying any deposit on an off-plan property:

Check the developer's registration with IMPIC. Obtain and verify the project's building permit (licença de construção) from the local Câmara Municipal (city council). Search the developer's name in the Conservatória do Registo Comercial (Commercial Registry) to check for insolvency proceedings, liens, or lawsuits. Demand a bank guarantee (garantia bancária) for your deposit and refuse to proceed without one. Have your lawyer review the CPCV (promissory contract) before signing.

Golden Visa Scam Brokers

Even though Law 56/2023 killed the real estate route for Portugal's Golden Visa, a cottage industry of scam brokers continues to profit from confused investors. These operations take several forms:

"Restructured" real estate schemes: Brokers claim they can structure a property purchase through a special fund or holding company that qualifies for the Golden Visa. While some legitimate fund structures include commercial real estate, any broker promising a residential property purchase that qualifies for Golden Visa residency is lying. The law is explicit: residential real estate is excluded.

Unregulated investment funds: Some brokers push "Golden Visa funds" that are not registered with the CMVM (Comissão do Mercado de Valores Mobiliários). Only CMVM-regulated funds qualify for the Golden Visa investment fund route. If a fund is not listed on the CMVM's public registry, it does not qualify, period.

Inflated fee structures: Legitimate Golden Visa legal and processing fees typically run €15,000 to €30,000 total. Brokers charging €50,000 to €100,000+ in "advisory fees" on top of the fund investment are extracting value, not adding it.

How to verify:

Search the CMVM's public fund registry for any investment fund presented as Golden Visa eligible. Check the broker's AMI license on the IMPIC portal if they are acting as a real estate intermediary. Ask for references from other investors who have successfully received their Golden Visa through the same fund. Consult an independent immigration lawyer, not one recommended by the broker.

How to Verify a Developer or Agent

Every real estate agent and agency in Portugal must hold an AMI (Atividade de Mediação Imobiliária) license issued by IMPIC. Operating without one is illegal under Law 15/2013.

Step-by-step verification:

1. Ask the agent or developer for their AMI license number. Legitimate professionals will provide this immediately.

2. Visit the IMPIC company search portal and enter the AMI number.

3. Verify that the company name, address, and license status match what you have been told.

4. For property-specific checks, request a Certidão Permanente (permanent certificate) from the Conservatória do Registo Predial through the Predial Online portal. This document shows the property's legal owner, any mortgages, liens, or encumbrances, and the property's legal description.

5. Request the Caderneta Predial (property tax document) from the Portal das Finanças. This shows the property's tax registration and assessed value.

Bektu aggregates developer information, project histories, and buyer reviews to provide an additional verification layer for foreign buyers who want independent data beyond what official registries offer.

Common Warning Signs Across All Scam Types

Pressure to "act now" before prices increase or units sell out. Reluctance to provide official registration numbers or license details. Contracts only available in Portuguese with no provision for certified translation. Requests for payment to personal bank accounts rather than company or escrow accounts. Agents who discourage you from hiring your own independent lawyer. Properties marketed exclusively to foreign buyers with pricing significantly above local market rates.

What to Do If You Have Been Scammed

File a complaint with the IMPIC if the scam involves a real estate agent or developer. Report financial fraud to the Polícia Judiciária (Portuguese criminal police). Contact your country's embassy in Portugal for consular assistance. Hire a Portuguese litigation lawyer (advogado) to pursue civil recovery. If the scam involved a Golden Visa investment, also report it to the CMVM.
