Sorry, it looks like the real estate option in Portugal is no longer available. :( Now it would take a €500K investment in a local business or €250K in a nonprofit. If you’re that stinkin’ rich, you probably have better options already.

According to globalcitizensolutions.com/real-estate-citizenshi… , Cyprus offers a citizenship path with real estate purchase of €300K. Greece and some other countries do, as well.
