The same villa costs $200,000 more on Phuket than on Samui

Thailand’s villa entry points are published plainly enough: from $300,000 on Koh Samui, from $350,000 in Pattaya, from $500,000 on Phuket. Three coastal markets, three starting figures, and a spread of $200,000 between the cheapest and the dearest. The houses at those price points are not wildly different in size or specification. The catalogue of Thailand houses for sale runs to 1,328 listings, and the gap between the islands says more about land, access and exit than about the buildings themselves.

For a buyer weighing the three markets as a business decision rather than a holiday preference, the question is what the extra $200,000 is purchasing. The answer breaks into four parts, and only one of them is the house.

Where the stock sits

Pattaya leads on volume with 487 houses, Phuket follows with 475 and Samui with 329. Bangkok has 18, which confirms that the villa market in Thailand is a coastal market. Those three resort totals are close enough that none of them can be called thin, but they behave differently because of how each place is reached and how each was built.

Pattaya is a road market. Two hours from Bangkok, it draws domestic weekend demand and expatriate residents who work in the capital or the eastern industrial corridor, and its land is flat and plentiful. Samui is an island served by a single airport with limited capacity and a ferry route. Phuket is an island with an international airport running 71 routes to 34 countries, 50 airlines and a record single day in February 2026 of 393 flights and 71,613 passengers.

What the extra money buys

Four factors carry the difference, in roughly this order of weight.

• Access. Phuket’s air connectivity means a house there can be reached directly from dozens of cities, which supports both personal use and any letting strategy. Samui’s connections run mostly through Bangkok, adding a transfer to almost every journey and narrowing the pool of buyers who will consider it.
• Land cost. On Phuket the developable coastal land was largely absorbed in the past two decades, and the island now splits roughly 83% condominiums to 17% landed homes. Scarcity prices land upward regardless of what is built on it.
• Depth of the buyer market. Pattaya’s province, Chonburi, took 36% of every foreign condominium purchase in the country in early 2026, some 1,167 registrations inside three months. That indicates an active, liquid market with continuous demand, and while the figure covers condominiums, the underlying flow of buyers supports the house market beside it.
• Services and staff. A managed villa needs pool maintenance, gardening, security and someone to check it when it is empty. Those services are established and competitively priced on Phuket, thinner on Samui, and inexpensive in Pattaya where the resident population is large.

The legal structure is identical everywhere

Whatever the price gap, the ownership question is the same in all three markets and it is the part that catches buyers out. A foreign national cannot own land in Thailand directly. Outright ownership exists for apartments alone, and even there it stops at a 49% share of each building, counted in floor space rather than in units.

A villa is therefore held either on a lease or through a Thai company. The lease route runs to 30 years as a matter of enforceable law. The stacked renewals advertised as ninety years lost their automatic force after the court decision of March 2025, and the 99-year term discussed since 2024 is still a proposal rather than law. The company route carries annual accounting, filing and governance obligations, and requires genuine substance rather than a nominal shell.

That means the $200,000 gap between Samui and Phuket is a gap between two leaseholds or two corporate structures, not between two freeholds. It changes how the exit should be modelled, because the buyer on the other side of that exit will be assessing the remaining lease term, not a title deed.

What to settle before choosing a market

• Decide how the property will be reached, honestly and repeatedly. A house that requires two flights will be used less than one that requires one, and use is the main return on a resort property.
• Model the exit before the entry. Ask how many comparable houses in the district sold in the past year and at what discount to asking, since a thin market on the way in is a thin market on the way out.
• Confirm the remaining lease term or the company structure, and have both reviewed by a Thai lawyer with no relationship to the seller or the agent.
• Put 2% of assessed value aside for registration and agree the split in writing before signing. The discounted rate that lapsed in June 2026 was a domestic measure and never covered foreign purchasers.
• Price the annual running costs of a coastal house, which in a tropical climate are higher than a European owner expects and do not pause when the house is empty.
• Check the seller’s holding period, since a seller who has owned for less than five years pays specific business tax of 3.3% and one who has owned longer pays stamp duty of 0.5%, and that difference sometimes shapes their willingness to negotiate.

Comparing the three markets side by side with plot sizes, project counts and completion dates in one view is the fastest way to see whether the premium is justified for a particular buyer. The Thailand house listings on Tranio sort by region and price band with the scheme size shown against each project.

The conclusion is that Phuket’s premium buys access and liquidity, Samui’s discount reflects the cost of getting there, and Pattaya prices a different market altogether, one driven by proximity to Bangkok rather than by tourism. None of those is a mistake. The mistake is paying the Phuket premium for a house that will be visited once a year, or taking the Samui discount and discovering that the next buyer wanted an easier journey.
