How to Buy a Private Island? The Ultimate High-End International Real Estate Investment
From childhood dream to reality, sometimes there is only one step. Buying a private island represents one of the most exclusive investments in high-end international real estate. This ultra-confidential market, reserved for a select group of high-net-worth individuals, sees island acquisitions reaching hundreds of millions of euros for the most prestigious properties.
Far removed from traditional Paris luxury real estate, purchasing a private island requires tailor-made support and in-depth expertise in the legal, tax and administrative constraints specific to each country.
Where can you find your dream private island? At what price? And above all, how can you secure such a unique acquisition?
Private Islands for Sale: A Booming Luxury Real Estate Market
Surprisingly, the market for private islands for sale is one of the segments of international luxury real estate that has benefited from the Covid-19 crisis.
According to the specialized agency Private Islands, inquiries related to buying a private island increased by 40% during the first lockdown, reflecting a growing appetite for secluded, self-sufficient locations offering freedom, privacy and security.
The price of a private island depends on several key factors:
-
Geographical location
-
Surface area
-
Accessibility (boat, seaplane, private airstrip)
-
Presence of existing infrastructure (fresh water, electricity, heating, buildings)
European islands are among the most expensive on the market. Entry-level luxury islands typically range between €1 million and €5 million.
Prestigious Private Islands: Investments Worth Tens of Millions of Euros
When a private island already features a fully equipped residence, budgets rise rapidly to several tens of millions of euros.
Among notable examples:
-
Emerald Cay, located in the Caribbean, is listed at €39 million. The property includes a luxury residence with a 6,000-bottle wine cellar, tennis court, volleyball court and two infinity pools.
