Greece has between 1,200 and 6,000 islands, according to a range of different estimates, and there is no definitive answer on how many the Greek government owns.
What we do know is that dozens of islands are up for sale and that for the country that is battling austerity measures and receiving a bailout from a number of international creditors — every cent counts.
On Private Islands Online, some islands are going for as little as €3 million (£2.1 million, $3.3 million). That's less than a house in an upmarket neighbourhood in London.
Over the last year, a number of islands have been sold via Private Islands Online but there are still a few up for grabs.
We checked out the islands that have visible price tags and ranked them by most expensive to the cheapest:
7. Dulichium Island — €40 million (£28.4 million, $44.1 million).
Location: Ionian Sea
Development: Non-developed
Size: 1,335.00 acres / 5.4 million square metres
This is the largest private island for sale in Greece right now. The highest point on the island is 250 metres above sea level. It has about 4,000 olive trees, shrubs, and dwarf bushes. It is undeveloped but presents an opportunity for someone to turn it into a luxury hotel resort.
6. Northern Aegean Island — €35 million (£25.9 million, $38.6 million).
Location: Chora
Development: Non-developed
Size: 86.00 acres / 348,029 square metres
This island is only half an hour away, by speedboat, from Athens. Numerous international developers are already showing an interest, according to Private Islands Online, because of the island's close proximity to the Greek capital.
5. St. Thomas — €15 million (£10.7 million, $16.5 million).
Location: Saronicos Gulf, near Corinth
Development: Non-developed
Size: 300.00 acres / 1.21 million square metres
St. Thomas Island is only 20 minutes away by water taxi from Corinth in Greece and only 45 minutes away from Athens. It is also part of the Diapori chain in the Saronicos Gulf, "an area of Greece mythologized for the lush emerald beauty of its picturesque islands."
