A private island, meaning privately owned island property rather than a separate nation, can cost under $100,000 at the cheapest broker-listed level, European CEO reports in European CEO's island market overview. At the luxury level, CEO Today estimates $10-$100 million to buy plus over $1 million yearly for upkeep. That range means required wealth runs from strong savings to billionaire resources.
The listing price alone misleads buyers. Building, staff, maintenance, and taxes decide long-term affordability. Match the island type to a yearly budget, not only the purchase price.

What can less than $350,000 buy?
Vladi Private Islands founder Farhad Vladi cites Round Island, Canada at about €53,000 as an entry example. The same broker range extends up to €84.7m for Pumpkin Key in the United States. Cheap therefore means small, remote, or undeveloped, not serviced.
Realtor.com reports a remote, water-access-only island in New Hampshire listed for less than $350,000. That price sat about $100,000 below the national median home price. Buyers still need boats, transport plans, and infrastructure funds.
When does an island signal billionaire wealth?
JamesEdition notes in its 2024 luxury island survey examples such as Bonefish Cay, Bahamas at $8.2 million and Gun Point, Bahamas at $23 million. It places the Bahamas and Florida among the highest-priced markets. Those prices buy location, access, and existing improvements.
CEO Today places billionaire-tier islands at $10-$100 million to buy plus over $1 million per year for upkeep. That upkeep sits separate from jets, staff, and security. Only ultra-high wealth absorbs that combination comfortably.
What does yearly upkeep demand?
Kepri Estates advises in its ongoing-costs guide budgeting 10-15% of island value yearly for maintenance and operations. It describes 5-10 full-time staff as typical. Staffing alone runs an estimated $50,000-$500,000+ yearly.
Use that math before making an offer. Caribbean property taxes run 1%-2.5% of value yearly, Kepri Estates reports. Buyer transaction, permit, insurance, and foreign-buyer fees add more. A $5 million island can therefore demand six figures yearly before improvements.
- Confirm year-round access, power, water, and waste systems.
- Price staff housing, transport, insurance, and turnover.
- Check property-tax rate, permits, and foreign-buyer fees.
What do building and legal limits add?
Mansion Global reports in its island development account that building a modest island from raw land often costs $1-5 million beyond purchase. It places a 50-foot dock around $250,000. Solar for a two-bedroom home runs $70,000-$80,000, with desalination at about $20,000.
Mansion Global also describes the Song Saa buyers spending 2.5 years resolving Cambodian land-law issues before securing a 99-year lease. Many Asian islands are leasehold, not freehold. Get local counsel to confirm lease length, transfer rights, and building approval before budgeting.
