How much do I need to invest to get the Greek Golden Visa?

“The minimum investment is €250,000 for commercial-to-residential conversion projects or the restoration of legally listed buildings, available anywhere in Greece. Standard residential properties require €400,000 in regions outside high-demand zones, or €800,000 in Attica, Thessaloniki, Mykonos, Santorini, and islands with populations above 3,100.”
