Forget the mega-yachts, private jets and Cartier jewels. The latest must-have accessory for the super-rich is a second passport or, at the very least, elite residency in a foreign country. A surprising number of nations worldwide offer residency and even citizenship in exchange for a minimum real estate investment. We reveal 30 countries where a property purchase will get you residency and even full citizenship.

Living in sun-kissed Fiji year-round may seem like the preserve of the mega-rich but you only need to invest a minimum of $125,000 (£94k) in a property there to qualify for permanent residency, plus you get full citizenship if you live in the country for five years or more.
