For Buyers
12 rules for buying an island
Prove your funds and identity
Before private viewings or information packs on high-value islands, buyers provide proof of funds (bank or private-bank letter) and pass KYC/AML checks. Islands are rarely mortgaged in the usual way — most are bought with cash, private-bank lending or a corporate structure.
Know exactly what title you are buying
Confirm whether the island is freehold, leasehold (and the remaining term), a concession, or only a right of possession. Obtain a certified extract from the land or public registry and an independent title opinion.
Check foreign-ownership law first
Many countries bar or limit foreign land ownership. Some allow it only with a permit, through a local company, or on a long lease. Confirm the route available to you before making an offer.
Budget for approvals and timing
Ministerial consents, investment-board permits or border-area approvals can add 2–6 months. Make your offer conditional on obtaining them.
Respect the foreshore
In most jurisdictions the beach below the high-water mark (and sometimes a setback strip above it) remains public or state land. "Private island" rarely means you can exclude people from the shoreline.
Commission full due diligence
Order a boundary/topographic survey, environmental and coastal-erosion assessment, hydrographic survey for docks and moorings, and structural surveys of any buildings. Check for protected species, marine parks and archaeological designations.
Confirm what you can build
Zoning, building density, height limits and environmental-impact requirements vary hugely. Get planning advice in writing; never rely on a seller's "approved plans" without seeing the permits.
Plan water, power and access
Islands need their own utilities: desalination or rain catchment, solar/diesel generation, waste treatment, and reliable boat, seaplane or helicopter access. Allow 5–10% of the island's value per year for running costs.
Use escrow — always
Deposits and purchase funds must be held by a licensed escrow agent or the notary/lawyer client account, released only on registration of title or lease. Never wire money directly to a seller or intermediary.
Understand taxes on purchase and ownership
Expect stamp duty, transfer tax or VAT on purchase (often higher for foreigners), plus annual property or land taxes, and possibly capital-gains tax when you sell. Take international tax advice on the holding structure.
Insure against nature
Hurricane, cyclone, storm-surge and liability cover can be expensive or limited. Get quotes during due diligence — not after completion.
Check sanctions and compliance
We cannot facilitate transactions involving sanctioned persons, entities or jurisdictions. All parties are screened.

For Sellers
Rules for selling your island
Proof of ownership and authority
Sellers must provide a current registry extract (or lease/concession document) and evidence that every legal owner — or the company board — has authorised the sale.
Full and honest disclosure
Disclose mortgages, liens, easements, existing leases or tenancies, disputes, unpermitted structures, environmental orders and any known erosion or contamination. Non-disclosure can void a sale.
Accurate listing information
Land area, tenure, permitted use and access details must be verifiable. Photos must be of the actual island and not digitally altered to misrepresent it.
Clear listing mandate
Choose an exclusive or non-exclusive mandate. The asking price, commission and marketing plan are agreed in writing before the listing goes live.
Confidential & off-market options
Sellers may list publicly, privately (verified buyers only), or fully off-market. NDAs are signed before sensitive information is released.
Cooperate with approvals
Sellers must support the buyer's foreign-ownership permit, lease assignment or government consent — e.g., lessor consent to assign a Maldives resort lease.
Tax clearance
Many jurisdictions require the seller to settle capital-gains or withholding tax, and provide tax-clearance certificates, before title transfers.
Islands we will not list
Islands with disputed title, unresolved indigenous/customary land claims, inside fully protected reserves where sale is prohibited, or in sanctioned jurisdictions.

FAQ
Frequently asked questions
Can anyone buy a private island?
Usually, yes — but how you can hold it depends on the country. Some allow foreign freehold ownership, others only long-term leases, and many require a government permit. See the country table above.
How much does a private island cost?
Islands start below $500,000 for small, undeveloped islands in lakes or northern waters, while developed tropical islands commonly range from $3 million to $50 million or more.
What are the running costs of owning an island?
As a rule of thumb, budget 5–10% of the purchase price per year for staff, maintenance, utilities, insurance, transport and taxes. Developed islands with resorts can be higher.
Can I get a mortgage to buy an island?
Conventional mortgages are rare. Most buyers pay cash or use private-bank lending secured on other assets. Some sellers offer vendor financing.
Does owning an island make me sovereign or exempt from local law?
No. Private islands remain part of the country where they are located and are subject to its laws, taxes and planning rules.
Can I keep people off my island beaches?
Often not entirely. In most countries the foreshore below the high-water mark is public, although you can control access to the land above it.
How long does it take to buy an island?
Typically 2–6 months from accepted offer to completion, depending on due diligence and any foreign-buyer approvals or lease assignments.
What does it cost to sell my island with you?
There is no upfront listing fee. A success fee, typically 3–6% depending on value, is payable only on completion and is agreed in writing beforehand.
