You might want to look at Greece, where a whole private island is being auctioned off for less than the cost of a standard family home - though there is a catch. Makri is an uninhabited, largely untouched, 243-acre island in the Echinades archipelago, lying about 4km off the coast of mainland Greece. It also sits around 30km east of Kefalonia, the largest island in the Ionian Sea.Virtually untouched by tourism, Makri Island boasts rugged hills, dense woodlands, and more than 7km of pristine coastline - a secluded paradise that you could potentially call your own.There have been multiple attempts to sell Makri over the past five years. High-end real estate agencies originally listed the island in 2022 with an asking price of €8million (£6.9million), aiming to transform it into a five-star luxury resort with villas.Makri was then given a starting price of €1.5 million (£1.19m) at an unsuccessful auction.This is because a closer look at Greece's strict environmental laws revealed it is legally a 'ghost asset' that cannot be developed on.
