01Greece or Portugal — they answer different questions
Greece is a property route: you buy, you hold, and there is no minimum stay at all, which suits an investor who wants Schengen access without moving. Portugal is a fund and business route — real estate purchase was removed from it in 2023 — and it asks for only a few days a year, but it is the one of the two that leads somewhere, because time on the permit counts towards naturalisation. Choose Greece for the asset and the freedom of movement; choose Portugal if a passport is the real goal.
02Thresholds, and what the money actually has to be
In Greece the entry point is tiered by location — the highest tier covers Attica, Thessaloniki, Mykonos and Santorini, a middle tier the rest of the country, and a reduced tier applies to specific conversion and listed-building projects, each with its own conditions on property size and use. Portugal's remaining routes run through qualifying investment funds, company formation with job creation, research and cultural heritage. We confirm the current figures and eligible categories against your filing date before you commit to anything, because both countries have moved them.
03Source of funds, the file, and local counsel
Both programmes stand or fall on proving where the capital came from. We build the paper trail with you — company accounts, sale contracts, dividends, inheritance, tax records — arrange the apostilles and certified translations, and coordinate with the licensed lawyer in Athens or Lisbon who files it. You keep one point of contact in Istanbul throughout, including the renewals.
