Quick answer: the choice is decided by title and by exit, not by yield. Phuket is the one Thai island with a deep foreign-freehold condominium market under the Condominium Act B.E. 2522 (1979) and a resale pool to match; Koh Samui is predominantly a leasehold market, which is a materially different asset that decays with its term; Koh Phangan has very little formally accessible foreign stock at all. Start with buying property in Phuket if liquidity at exit matters to you.
Thailand’s islands are not equal as investment markets, and the differences matter more than most buyers realise before they start. The choice between Phuket, Koh Samui, Koh Phangan, and the smaller islands is not just a lifestyle preference, it determines your ownership options, your yield potential, your legal exposure, and your long-term liquidity.
This guide compares Thailand’s main islands for property investment in 2026 with specifics on ownership structures, market data, rental yields, and an honest verdict on each. Deep dive: Phuket vs Koh Samui comparison.
Why Island Property Appeals to Foreign Investors?
The case usually made is tourism: arrivals fill short-stay bookings, short-stay bookings pay more per night than a resident tenant does, and the islands take a disproportionate share of both. That much is structurally true and it is why island stock is sold on nightly income rather than on monthly rent.
What the case usually skips is that nightly income is only available where the building can legally take it. The Hotel Act B.E. 2547 (2004) makes a letting of under 30 days hotel business, licensable as such, and a condominium’s co-owner regulations can rule short lets out on their own account even where the licence exists. That test is applied building by building, not island by island, and it is the single most common reason a yield projection fails to arrive.
The second thing the case skips is that the islands do not offer the same ownership. Foreign freehold exists in Thailand only in condominiums, inside the 49% of a building’s floor area the Condominium Act reserves for non-Thai owners. Where an island has few condominiums, it has little foreign freehold, and everything else on offer there is a lease or a company. That is not a detail of the paperwork. It changes what you own, what it is worth in ten years, and who can buy it from you.
Phuket: The Market Leader
- An international airport with direct long-haul routes, rather than a regional one
- Foreign freehold available in condominiums, inside the Condominium Act’s 49% of each building’s floor area
- Real depth of supply: MORE Group’s own project records hold 14,322 priced units across 297 developments on this island alone
- An active resale market with established price history, and the deepest foreign buyer pool of any Thai island
- Banking, legal and professional management infrastructure that handles foreign transactions daily
That third point is the one that separates Phuket from every other island in this comparison, and it is worth putting a number on because “market depth” is otherwise a word. Across those records the market divides cleanly by budget: 3,221 priced units under 5,000,000 THB, 6,058 between 5 and 10 million, 2,441 between 10 and 20 million, 2,128 between 20 and 50 million and 474 above. Whatever a buyer’s budget, there is stock in it, and, crucially, there is comparable stock for the next buyer to price against when you sell.
Ownership options for foreigners: an apartment can be held freehold in your own name inside the building’s 49% foreign quota, which is the clean route and the one most foreign buyers take. Land cannot: the Land Code reserves it for Thai nationals, so a villa arrives as a registered lease of the plot with the house held separately, or through a Thai company that owns the land. Both routes work and both need care. A lease registers under the Civil and Commercial Code for a maximum of 30 years in one term, so anything marketed as 30 plus 30 plus 30 is one registered right followed by two contractual promises, and the value of those promises depends entirely on who is making them. A company route runs into Land Code Section 96, which prohibits holding land through a nominee, and that is why the shareholders have to be real and the counsel has to be yours rather than the seller’s.
Which zones cost what: on MORE Group’s price records, the rate per square metre for apartments runs from 234,004 THB in Patong down to 92,515 in Si Sunthon, with Choeng Thale at 158,000, Karon at 157,000, Kamala at 156,140 and Rawai at 140,208. Choeng Thale is also by far the deepest, holding 6,291 of the priced apartments in the records against Patong’s 202. Zone detail: best areas to buy in Phuket. Yield method: Phuket rental yield guide.
The case for Phuket: if what matters is a clean freehold title and being able to sell when you choose rather than when a buyer appears, this is the island. It is the most mature market of the three, the most professionally managed, and the only one where the next buyer has comparable transactions to price your unit against.
Which Phuket stock fits your budget and your exit?
We will send a shortlist from the current price lists with the quota position and the letting rules of each building stated, not assumed.
Koh Samui: The Leasehold-Heavy Alternative
The property investment picture on Koh Samui differs from Phuket in one critical structural way: freehold condominium development is far less common. The majority of foreign-accessible property on Samui is offered as leasehold, typically 30-year terms with options to renew, which affects the ownership profile significantly.
Ownership options: Leasehold is the norm. Well-structured leasehold agreements on Samui with renewal options and proper registration at the Land Department are legal and can work effectively, but they represent a fundamentally different asset than freehold. At the end of the lease term, the property reverts to the land owner unless renewal is exercised. Exit liquidity depends on the lease remaining term, units with 15-plus years remaining lease have a decent buyer pool; units with under 10 years remaining become significantly harder to sell.
What the leasehold discount is actually for: a lease is a wasting asset and a freehold is not, and the price gap between the two is the market pricing that fact rather than pricing the beach. A 30-year term bought at year one and sold at year twelve is an 18-year term to its next owner, and the pool of buyers willing to take an 18-year term is smaller than the pool that would take a freehold. That is the whole mechanism, and it operates whatever the island.
It has one practical consequence worth stating plainly: on a lease, the sale price and the remaining term move together, so the exit has a clock on it that a freehold purchase does not. The time to think about that is before the deposit, not in year twelve.
The 6-month monsoon consideration: Koh Samui’s monsoon season runs from approximately October to January, roughly the opposite of Phuket’s shoulder/low season. This means Samui has a different occupancy curve: its high season peaks around the European and Russian winter months when Phuket is also at peak, but its low season coincides with Phuket’s high season. For investors, this creates potential for a split-season portfolio strategy, but for single-island investors on Samui, the October-January low season occupancy can meaningfully drag annual yield numbers.
Verdict for Samui: a credible choice for a buyer who is buying to use rather than to trade, or who already has Phuket exposure and wants something different alongside it. As a standalone investment it is the second answer, because the leasehold structure puts a clock on the exit that Phuket freehold does not.
Koh Phangan: Niche Appeal, Legal Limits
The legal reality: Foreign ownership options on Koh Phangan are more restricted than on either Phuket or Samui. There is essentially no freehold condominium market, and the leasehold villa market is smaller and less professionally managed. Many transactions happen informally, which creates legal risk for foreign buyers who do not engage proper representation.
Pricing and the demand base: entry prices are lower than on either of the other two islands, which is most of the appeal. The demand that fills the properties, though, comes from a narrow band of wellness retreats, festivals and long-staying nomads, and a demand base that narrow is more exposed to a change in fashion than one built on a general tourist market. Where the income depends on a scene rather than on an airport, the risk is that the scene moves.
The case for Koh Phangan: The island is interesting as a niche play for buyers who are deeply embedded in the wellness and retreat market and can actively manage occupancy. As a passive investment with professional management, the infrastructure is not yet mature enough to be reliable. Buyers should approach with caution and thorough legal due diligence.
Other Islands: Koh Lanta, Koh Chang, and the Rest
Koh Lanta (Krabi Province) has a small property market with limited foreign investment infrastructure. Land title status can be complicated, some areas have strong chanote title, others have weaker documentation. The tourist market is smaller and more seasonal than Phuket.
Koh Chang (Trat Province) is close to the Cambodian border and has a domestic tourism market that is strong among Bangkok residents but relatively small international component. Foreign ownership options are limited, and the investment case is primarily for Thai nationals.
Koh Tao and Koh Nang Yuan are dive destinations with a strong niche tourism market and essentially no accessible foreign property market. What exists there is operated as business ventures rather than as individual investment property.
The common thread across all four is title. On the smaller islands a significant share of land is held on documents weaker than a Chanote, and the marketing line that a title will be “upgraded soon” is a request that you pay a Chanote price for something that is not one. Establish the title class before the price, not after.

How do the three compare, side by side?
| Phuket | Koh Samui | Koh Phangan | |
|---|---|---|---|
| Foreign freehold | Available in condominiums, inside the 49% quota | Very limited condominium supply | Effectively none |
| Usual route for a villa | Registered lease or Thai company | Registered lease | Registered lease, often informally arranged |
| Depth of priced stock | 14,322 units across 297 developments in MORE Group’s records | Thinner, and weighted to villas | Thin |
| Air access | International airport with direct long-haul routes | Regional airport, limited routes | No airport, reached by ferry |
| Who buys from you | The deepest foreign resale pool of the three | Smaller, and shrinks with the lease term | Narrow, and specific to the retreat market |
| The main risk to check | Quota position and the building’s letting rules | Lease term, renewal wording and succession | Title class and whether the transaction is properly documented |
Read the table down the last row rather than across the first. Every one of these islands can be bought well; what differs is what has to be verified before the deposit, and how long a mistake takes to unwind.
Red flags when comparing Thai islands
| Red flag | Why it matters | Island risk |
|---|---|---|
| Lease under 10 years remaining | Buyer pool shrinks; lenders walk | Samui, Phangan |
| No Land Department registration | Unenforceable lease | All non-Phuket villas |
| ”Upgrade to Chanote soon” marketing | Paying premium for NS3 land | Phangan, Lanta |
| Yield quoted on peak week only | The full-year figure is a different number entirely | All islands |
| No professional management track record | Passive income thesis fails | Phangan, Lanta |

Island decision framework by buyer profile
Scenario A: family buying for school-holiday use: a Phuket two-bedroom, or a Samui three-bedroom leasehold with 20 or more years still to run. Underwrite the Samui option on the assumption that October to January produces very little, because that is its low season, and check whether the school holidays you actually travel in fall inside it.
Scenario B: buyer pursuing a long-stay visa alongside the purchase: Phuket freehold, because the LTR routes that can count a Thai asset are income and investment tested and the thresholds are revised, so the property has to be a clean, valued, transferable title rather than a lease with a term on it. Pair with the Phuket complete guide 2026, and confirm the current thresholds with immigration counsel rather than with any guide. Property never grants residency by itself anywhere in Thailand; a qualifying investment can count toward a category threshold, which is a different thing.
Scenario C: Buyer who wants a villa and will hold for decades: The ownership question decides this before the island does. No foreigner holds freehold land in Thailand, so a villa anywhere is a registered lease or a company structure, and a lease decays as its term runs down. If that horizon exceeds the term, buy on the understanding that you are purchasing use rather than an asset to pass on.
Scenario D: Buyer who may need to sell within five years: Phuket, and not close. Liquidity is the single largest practical difference between these islands, and it only matters at the moment you need it, which is exactly when it cannot be arranged.
When Samui beats Phuket, honestly
Phuket wins the general comparison on liquidity, ownership options and management depth, and this page says so throughout. There are nonetheless cases where Samui is the better answer, and pretending otherwise would be a sales pitch rather than a guide.
Samui beats Phuket when the buyer wants a villa in a genuinely quieter setting and is buying to use rather than to trade. The island is smaller, less developed and less busy, and for someone who finds Phuket’s high season overwhelming that is the whole point. Leasehold is the normal route there for foreigners and it is a real constraint, but for a buyer with a long personal-use horizon and no plan to sell quickly, the constraint bites less than it would for an investor.
It also wins where the specific property simply does not exist in Phuket at the price. Samui’s villa stock at a given budget is often larger and better positioned than the Phuket equivalent, because the underlying land is cheaper. If what you want is space and seclusion rather than services and liquidity, that trade can be worth making with your eyes open.
Where it does not win is on exit. The foreign buyer pool is thinner, freehold condominium supply is very limited, and a sale takes longer. Anyone who may need liquidity should weight that heavily.
Timing: best time to buy Phuket property, Samui’s low season (Oct-Jan) can be a counter-cyclical viewing window while Phuket peaks.
Frequently Asked Questions
Yes, but with different structures on each island. Phuket offers freehold condominium ownership within the 49% foreign quota, the cleanest option. Koh Samui is primarily a leasehold market for foreign buyers, with very limited freehold condominium supply. Koh Phangan has the most restricted foreign ownership options, with a small leasehold market and limited professional infrastructure.
There is no island-wide figure worth quoting, because the number is set building by building: whether short lets are legally available there, who manages them, and what the unit actually achieved last year. Ask the manager for a full year of statements on a unit like it in the same building, take out commission, maintenance, utilities across the empty months, furnishing replacement and Thai tax, and divide what remains by the price plus the cost of buying. Any percentage offered before that exercise is an estimate.
A lease registered at the Land Department is a real legal right, and under the Civil and Commercial Code it registers for up to 30 years in one term. The risks are structural rather than exotic: renewals beyond that term are contractual promises rather than registered rights, so their worth depends on who gives them and whether a later owner of the land is bound; the resale price falls with the remaining term, because the next buyer is buying what is left of it; and financing is rarely available against a lease. Use independent counsel you appointed, and read the succession clause as carefully as the term.
Phuket, without comparison. It has an international airport with direct routes from over 30 countries, a full legal ecosystem for foreign property transactions, established professional property management companies, active banking relationships for rental income, and the deepest pool of foreign resale buyers. No other Thai island comes close on infrastructure for passive foreign investors.
No. Buying property in Thailand grants no right to live in it, and no Thai visa follows from ownership by itself. Some Long-Term Resident routes are qualified for partly on investment in Thai assets, which can include property, alongside income or pension tests. The thresholds and the qualifying asset classes have been revised more than once, so confirm the current terms with immigration counsel before planning a purchase around them, and settle the stay before the purchase rather than after.
Liquidity differs more than price
Comparing Thai islands on entry price alone hides the variable that decides your result, which is how easily you can sell. Phuket has an international airport with direct long-haul routes, a resident foreign community and a resale market with regular transactions. Smaller islands may offer a lower price per square metre and a better beach, but a buyer pool that thins to almost nothing outside the peak season. Before comparing prices, compare exits: ask how many foreign-quota resales completed on each island last year. Where that number is low, treat the purchase as a lifestyle decision and assume you may hold it for a long time.
