No category of real estate is more mythologised or more misunderstood. Private islands are scarce, the transaction mechanics are unlike anything else in property, and the price spread is wider than in any other segment: a Finnish archipelago island can be had for the price of a car, while the most expensive listing in the Caribbean asks $125 million.
The distinction most coverage misses is between islands genuinely on the market and islands that appear on rankings because they once were. Trophy islands trade rarely and quietly, they are frequently withdrawn and relisted at revised prices, and a name appearing on ten "for sale" lists may have changed hands years ago.
What follows are ten assets genuinely available in the current market cycle, at the prices they were marketed. Availability changes constantly, and any island below may have transacted, been withdrawn or been repriced since publication. Verify with the named brokerage before you plan anything.

1. Blue Island, Exuma Cays, Bahamas: About $125 Million
The Caribbean's ceiling. Blue Island spans 700 acres across the Exuma Cays with more than three miles of coastline, elevations reaching around 100 feet and multiple internal lagoons.
What separates it from every other island in the region is infrastructure most sovereign territories would recognise: a 5,700-foot asphalt airstrip capable of receiving private jets directly from the United States or Europe, its own customs and immigration facilities, a main house, staff housing and roughly four miles of internal roads.
The immigration post is the detail that matters. On almost every private island on earth, arrival means clearing customs on the mainland first. Blue Island removes that step, which is a functional difference rather than a marketing one. It has been marketed between $75 million and $125 million across its listing history and its status has been reported inconsistently, so confirm current availability directly.
2. Tarpon Island, Palm Beach, Florida: Sold at $150 Million
The most instructive transaction in the private island market, and the most extreme price per acre ever recorded.
In May 2024 a 2.3-acre island in the Palm Beach Intracoastal Waterway sold for $150 million to a buyer using a Delaware LLC whose identity stayed undisclosed for days. The seller had paid $85 million for the same parcel three years earlier, then developed it.
That is roughly $65 million per acre, against Caribbean trophy islands trading closer to $150,000 to $200,000 per acre. What you buy in Palm Beach is not land. It is a fully built, fully serviced, fully connected private island four minutes from a mainland with hospitals, staff, provisioning and an international airport. That premium, roughly 300 times the Caribbean rate, is the price of removing every operational problem described later in this article.
3. Ronde Island, Grenada: Marketed Near $100 Million
One of the largest privately held island opportunities in the Caribbean, lying between Grenada and Carriacou across roughly 2,000 acres. Its value case rests on scale and development potential rather than existing infrastructure, and it has historically been positioned for resort or master-planned development rather than single-family use.
Grenada is also the only Caribbean nation combining citizenship by investment with both visa-free China access and United States E-2 treaty eligibility, which gives a purchase there a secondary strategic dimension. Our guide to residency and citizenship through property investment covers how that programme works.
4. Pumpkin Key, Florida Keys: $75 Million to $95 Million
A perennial fixture on trophy property lists and the most practically usable large island in North America. Pumpkin Key sits minutes by boat from the Ocean Reef Club, giving owners a full private club ecosystem including dining, golf, marina services and an airstrip without having to build any of it.
The 26-acre island carries a main residence, guest cottages, staff quarters, a helipad, a 20-slip marina and approved homesites. It has been marketed most prominently at $95 million and more recently around $75 million.
5. A 381-Acre Island, Turks and Caicos: About $75 Million
Turks and Caicos combines the strongest legal framework in the Caribbean for foreign ownership with genuine tourism demand and no direct taxation. A 381-acre offering at $75 million works out at roughly $197,000 per acre, close to the regional benchmark for large undeveloped trophy islands.
Islands at this scale in TCI are almost always acquired with a development thesis rather than a residential one, given the ratio of land to what any single family can meaningfully occupy.
6. A 376-Acre Island, St Vincent and the Grenadines: About $54 Million
The Grenadines are the Caribbean's yachting heartland, and this is where price per acre starts to look reasonable next to the Bahamas and Florida. At around $144,000 per acre across 376 acres, this is the value end of the serious trophy segment.
The trade-off is access. The Grenadines require more connections than the Exumas, which is precisely why the acreage is cheaper.
7. North Eleuthera Estate Island, Bahamas: $45 Million
A different proposition from the raw acreage plays above. This asset carries deep-water anchorage, direct airstrip access and existing resort development approvals, which is the combination that determines whether an island can be commercialised or only inhabited. It is listed through HG Christie.
At this level the relevant benchmark is not other islands. It is branded resort real estate, because that is what the buyer pool compares it against. Bahamian ownership is freehold, with government registration required for parcels above two acres.
8. Haines Cay, Bahamas: About $37.9 Million
Three hundred acres of undeveloped land with white powder beaches, creeks, mangroves and bluffs, marketed through Engel and Volkers Bahamas. The sale has included a developer's package on Great Harbour Cay, 600 feet across a creek, which effectively bundles a mainland service base with the island.
That structure solves the single largest operational problem in island ownership: where the staff live, where supplies land, and where the boats are maintained when the weather closes in.
9. Katafanga Island, Fiji: 225 Acres, Lau Group
Katafanga brings substantial groundwork already completed, which in the South Pacific is worth more than the land itself. It carries villa construction, an airstrip, a water reservoir and a road circling the island, and it sits within a 5,000-acre natural lagoon in the Lau Group, among the most coveted locations in the Fijian archipelago.
The critical due diligence point in Fiji is title. Freehold covers only around 8% of Fijian land. Most island transactions are leasehold, and a leasehold island with 50 years remaining is a fundamentally different asset from a freehold island with identical beaches.
10. Wavi Island, Fiji: From About $15 Million
The clearest entry point into genuine island ownership in the Pacific. Wavi sits near Savusavu Airport on Vanua Levu with 27 acres of freehold land, an operational guest pool, bar, tennis court and marina, plus nineteen vacant development plots. It went to international auction through Sotheby's International Realty in December 2025.
Freehold designation makes it genuinely rare. Combined with proximity to a functioning airport, it is arguably the most practical island here for a buyer who intends to use it rather than develop it.
What Islands Cost Outside the Trophy Tier
The category is not exclusively a billionaire's game, and the price floor is far lower than most people assume.
| Region | Entry point |
|---|---|
| Finland and Sweden | From around EUR 34,000 for archipelago islands with existing cabins |
| Canada (Nova Scotia) | Regularly under $100,000 for lake and coastal islands |
| Ireland | From around EUR 120,000 |
| Belize and Nicaragua | From roughly $225,000 for small undeveloped cays |
| Bahamas | From around $500,000 |
| Indonesia | From around $900,000 |
| Croatia and Italy | From around EUR 1.5 million |
| Fiji | From around $1.7 million |
| Greece and French Polynesia | From around EUR 2.2 million |
The Caribbean accounts for over 40% of all private island listings globally, with the Bahamas alone holding hundreds of islands and cays in private hands.
The Listing Price Is Roughly Half Your Actual Spend
This is the number that changes every buyer's arithmetic. Analysis across multiple jurisdictions consistently finds that buyers of undeveloped islands spend approximately 1.8 times the listing price before the island is habitable.
Power generation, desalination or water catchment, waste treatment, dock and seawall construction, staff accommodation, a boat fleet, communications, and construction logistics where every bag of cement arrives by barge. A $10 million island is an $18 million project, and the timeline is measured in years rather than months.
The islands commanding extreme premiums, Palm Beach at $65 million per acre or Blue Island with its own airstrip and customs post, are priced that way precisely because someone already absorbed this cost.
You are never buying an island. You are buying however much of the infrastructure problem the last owner already solved.
Ownership Structure Varies More Than Price
Jurisdiction determines what you own, and it is frequently not what a buyer assumes.
- Freehold available: the Bahamas (registration required above two acres), Italy, Turks and Caicos, Panama, Canada, Finland and most United States states.
- Freehold rare: Fiji, where freehold covers around 8% of land. Verify title before anything else.
- Foreign purchase restricted: French Polynesia restricts foreign residential island purchase, and Brazil requires government approval for coastal property.
- Leasehold only: Vanuatu and Tonga operate long-term leases. A 2026 clarification confirmed that foreign leases there do not include adjacent marine areas, meaning you may hold the land without holding the water around it.
- No foreign land ownership at all: the Philippines, Indonesia and Thailand. All foreign island holdings run through leases or corporate vehicles, and prices per acre are among the highest globally because of hotel developer demand.
Panama offers the most straightforward foreign ownership process in the Americas, with the same property rights as citizens and no coastal restrictions.
Islands Are Illiquid in a Way No Other Asset Is
Private islands do not perform well at auction. Innocence Island in the Bahamas, listed at $55 million in 2013, sold at auction for $17 million, a $38 million discount, with bidding opening at $8 million and stalling within minutes. The seller was terminally ill and wanted cash rather than the asset for his children. The buyer pool for a $20 million island is small, geographically scattered and physically difficult to bring to a viewing.
The counter-example is instructive. Richard Branson paid approximately $180,000 for Necker Island in 1979, and its estimated current value is around $100 million. But Branson did not simply hold land. He built a brand around it: a Balinese-style villa, a kitesurfing culture and a guest list of heads of state. The appreciation followed the story, not the acreage.
Buy an island as a use asset with a very long horizon. Do not buy one expecting to exit on your own timetable. The same discipline applies to the trophy end of conventional property, as our ranking of the most expensive villas ever sold shows.
Before You Buy
Island ownership sits at the intersection of property, marine access and immigration law, and each one can undo the others. Establish title and marine rights before price. Budget the development multiple, not the listing. Confirm the brokerage still holds the mandate. And treat the tender and support fleet as part of the asset rather than an afterthought, which is where our yacht listings and the wider Real Estate journal come in.

Frequently Asked Questions
Can you actually buy a private island?
Yes. There are typically hundreds of private islands on the open market worldwide at any moment, ranging from under EUR 40,000 in Finland to more than $125 million in the Bahamas. The main constraint is not availability but jurisdiction, since several countries restrict or prohibit foreign land ownership.
How much does a private island cost?
Entry-level islands in Nova Scotia and Finland start below $100,000. Small undeveloped cays in Belize and Nicaragua start around $225,000. Serious Caribbean trophy islands run from roughly $15 million to $125 million. Making an undeveloped island habitable typically costs around 1.8 times the purchase price on top.
What is the most expensive private island for sale?
Blue Island in the Bahamas has been the highest-priced listing in the Caribbean at approximately $125 million for 700 acres, complete with a 5,700-foot jet airstrip and its own customs and immigration facilities. Availability should be confirmed directly with the listing brokerage.
Which countries let foreigners buy islands outright?
The Bahamas, Turks and Caicos, Italy, Canada, Panama, Finland and most of the United States offer freehold to foreign buyers. Fiji offers freehold on only around 8% of its land. The Philippines, Indonesia and Thailand prohibit foreign land ownership entirely, requiring lease or corporate structures.
Do you own the water around a private island?
Generally no. Marine areas are almost always sovereign. A 2026 clarification confirmed that foreign leases in Vanuatu and Tonga specifically do not include adjacent marine areas. Anchorage, mooring and reef rights are separate questions to establish before purchase, not after.
Are private islands a good investment?
They are illiquid, expensive to hold and difficult to exit. They have performed exceptionally for owners who developed them and built demand around them, and poorly for owners who needed to sell quickly. Innocence Island, listed at $55 million, sold at auction for $17 million. Treat one as a long-horizon use asset rather than a portfolio position.
What is the cheapest private island you can buy?
Archipelago islands in Finland and Sweden start from around EUR 34,000, often with an existing cabin, and Canadian lake and coastal islands in Nova Scotia regularly trade under $100,000. These are genuine freehold purchases, though they carry the same access, power and water constraints as any island.
How much does it cost to develop a private island?
Budget roughly 1.8 times the purchase price before the island is habitable. That covers power generation, desalination or water catchment, waste treatment, dock and seawall construction, staff accommodation, boats, communications and barge logistics for every material delivered. The timeline runs to years rather than months.
Which Caribbean island nations are best for foreign buyers?
Turks and Caicos offers the strongest legal framework with no direct taxation, and the Bahamas offers freehold with government registration required above two acres. Grenada adds a strategic layer through its citizenship programme, which combines visa-free China access with United States E-2 treaty eligibility.
