How to Buy a Private Island: Prices, Ownership Rules and Due Diligence (2026)

Buying a private island starts with one question: can a foreigner hold full title there? In the Bahamas, Belize and the British Virgin Islands the answer is generally yes, with permits and transfer taxes, and in Florida it is yes for most buyers; in the Maldives and the Philippines foreigners cannot own land outright. After that come the costs nobody lists on the brochure: power, water, boats, staff and insurance. This guide covers prices, the rules in the most popular markets, what to check before you sign and the questions to ask, as of October 2026.

Ownership laws change, and every island is different. Work with a licensed local attorney and broker before you commit. Nothing here is legal or tax advice.

What Private Islands Cost

Galerie magazine reported in 2019 that islands range from under $100,000 to more than $100 million. On October 29, 2026, the featured listings on Private Islands Online, the listing site of Private Islands Inc., ran from about USD 2.1 million to USD 400 million, and the site also showed collections of islands under $500,000. Finder, a consumer finance site (guide updated June 2026), says a Caribbean island costs “at least $1 million.” Some listings are “price upon request.”

The purchase price is often the smaller number. Finder notes that water treatment, waste systems and solar power “can cost hundreds of thousands of dollars” before a house is built, and that banks typically don’t lend on islands, so buyers should expect to pay cash.

Freehold, Leasehold or Concession?

With freehold title you own the land outright. With a leasehold you rent it from the state or a landowner for a fixed term. In some countries, islands or the shoreline can only be held under a government concession. Know which one you are buying before anything else:

• Maldives: a constitutional amendment gazetted on April 23, 2019 prohibits transferring ownership of land to a foreign party. Foreigners can lease for up to 99 years.
• Philippines: the Constitution limits private land to those qualified to hold public land, which in practice means Filipino citizens and companies at least 60% Filipino-owned.
• Fiji: about 87% of the country is iTaukei (native) land, which foreigners can lease but not buy, according to OneRoof (October 2026).
• Panama: private ownership of islands is restricted, and possessory rights (“derecho posesorio”) do not give you title, according to the law firm Patton, Moreno & Asvat (2017). Confirm current rules with a Panamanian attorney.

The Rules in Popular Markets

Two points in the Bahamas are worth confirming with a local attorney: lawyers’ guides differ on the acreage of undeveloped land that triggers the stricter permit route, and on whether an annual tax applies to vacant land owned by non-Bahamians on the Family Islands.

Due Diligence: What to Check Before You Sign

• Title and survey: confirm who holds title, what kind of title it is, and that a registered survey matches the island you visited. In Panama, possessory rights are not title; in the Bahamas, a purchase without a required permit is void.
• Shoreline and seabed: in Panama, land within 22 metres of high tide on the Pacific and 10 metres on the Atlantic cannot be titled. In Florida, title to sovereignty submerged lands is held by the state, so ask what approvals any dock or seawall work would need.
• Power and water: Tim Rodland of Rodland Real Estate in Nassau told Mansion Global that power generation is one of the most expensive parts of developing a private island. Ask for the history and running costs of generators, solar systems and desalination.
• Access: how will you, your staff and your building materials get there? Rodland notes that you often need a barge.
• Building rules and deadlines: some countries require you to build within a set time. Fiji sets a building deadline for some non-resident buyers; the 2014 amendment’s text says 24 months, while the law firm Munro Leys and OneRoof report five years, so confirm the current rule.
• Climate and politics: check hurricane exposure, sea-level risk to shoreline homes and the country’s political history before you commit.
• Rent first: both Farhad Vladi of Vladi Private Islands and Chris Krolow of Private Islands Inc. have advised renting an island before buying one.

Running Costs

Few owners publish their budgets. In a 2012 Reuters article, Krolow suggested about $50,000 a year for a caretaker for owners who aren’t there year-round and said one client spent $300,000 on a barge; the article put reverse-osmosis water systems at $6,000 to $10,000. Costs have risen since, so treat these as a floor and get current quotes for staff, fuel, insurance and maintenance.

Who Sells Private Islands

Private islands are sold by specialist island brokers and by the international luxury brokerages, usually working with a licensed local agent:

• Private Islands Inc. runs the Private Islands Online listing site.
• Vladi Private Islands, based in Hamburg, made its first island sale in 1971, according to Yacht magazine.
• Knight Frank, founded in 1896 and headquartered in London.
• Savills, founded in 1855 and listed on the London Stock Exchange.
• Sotheby’s International Realty, one of the international luxury brokerages.
• Christie’s International Real Estate.

Listing sites show what is available; the local attorney and broker are who make the purchase work.

Questions to Ask Before You Buy

1. Is the title freehold, leasehold or a concession, and who holds it today?
2. What permit or licence do I need, how long does it take, and what happens if it is refused?
3. What are the total transfer taxes and fees, and who pays them?
4. Are there building deadlines or taxes on vacant land?
5. Where do power and water come from, and what do they cost to run each year?
6. How do people, supplies and building materials reach the island?
7. What can be built near the shoreline, and who controls the seabed?
8. Can I rent the island, or a similar one nearby, before I buy?

The Bottom Line

Choose the country before the island: whether you can hold title, what permits you need and what tax you will pay decide whether a listing is real for you. Then budget for infrastructure, access and staff, check the title and shoreline rules with a local attorney, and rent before you buy if you can.
