Villas for sale in Koh Samui

Small estates, one builder at a time

Of the 145 projects that state a unit count, 135 hold twenty-five houses or fewer and 98 hold ten or fewer; the median project has 8. Our island comparison describes Samui as predominantly a boutique and single-project market, where the selling company is often formed for one estate and has no earlier handover you can go and look at.

The Koh Samui market page explains why so many are already built: these estates are mostly financed as the builder goes and sold on completion or during a short build. That is why 137 of the 145 projects here are finished houses rather than plans. It also explains the gaps on the cards. Only 65 name a developer, and a firm with eight houses to sell rarely publishes much more than a price and a brochure.

The price gap with Phuket is real but needs reading carefully. The median entry price here is 12,900,000 THB, against 27,076,000 THB across 129 Phuket villa projects on this site. Both figures are starting prices for whatever the cheapest house in each project is, so compare plot size, bedrooms and the lease term before treating the difference as a saving.

Bo Phut, Maenam, Lamai or the quiet south and west

Bo Phut is the north-east corner: Fisherman’s Village, the Bang Rak and Plai Laem headlands facing the airport, Choeng Mon and the Chaweng Noi hillside. The airport, Bangkok Hospital Samui and Central Festival are a short drive away, which is why the island’s premium villas cluster here and why its entry prices are the highest. Our premium-buyer guide adds that Bo Phut and Choeng Mon carry the strongest resale stories on the island, while resale liquidity stays thinner than in Phuket’s Bang Tao.

Maenam, along the north coast toward Nathon, has a long calm beach, few large hotels and a growing number of villa estates in the sois behind the ring road. A comparable villa costs less than in Bo Phut, and the airport is twenty to twenty-five minutes by road.

Maret is the Lamai side, the island’s second beach town on the south-east coast. The hills behind Lamai hold a large share of the sea-view villa projects, about thirty minutes from the airport. Further round, Na Mueang has cheaper land and bigger plots with Lamai as its nearest town, Taling Ngam is roughly forty-five minutes from the airport and the quietest district we list, Lipa Noi on the west coast has few projects, and Ang Thong sells on price and on being near the ferries.

Read the district table together with the project table. The cheapest district does not always hold the cheapest house, and a single low entry price can belong to one small plot in an otherwise dear area.

Who holds the plot under a Samui villa

You can own the house; you cannot own the ground under it as a foreign individual. The plot is held either on a lease of no more than 30 years registered at the Koh Samui branch of the Surat Thani Land Office, or by a Thai limited company with real Thai shareholders. When a Samui listing says freehold, it is describing what a Thai buyer or a company would receive.

Read the lease term literally. What is marketed as 30+30+30 is one registered term plus two contractual promises to grant further terms, enforceable against whoever made them rather than registered against the land, as the premium-buyer guide sets out. Our island comparison advises getting the remaining lease years in writing before you set a Samui villa price against a Phuket freehold comparable.

Then look behind the plot. It should carry its own deed, a Chanote or a Nor Sor 3 Gor, and an estate that has not yet subdivided its land cannot register your lease against an individual plot. Only 33 of the 145 cards state any title structure, because most source listings leave it out; for the rest, the title is a question for the seller before you pay anything.

Before a deposit on an off-plan Samui villa

8 projects on this page are still being built. With single-project companies, the checking falls almost entirely on the buyer: there may be no previous estate to inspect and no comparable sale to price against. The premium-buyer guide is direct about why it matters, noting that project defaults have occurred on the island.

Four terms belong in the contract before money moves: instalments tied to construction stages, a penalty and a refund right if delivery slips, a building permit that names your plot, and the developer’s record on its earlier estates. Two checks are particular to Samui. Planning rules close hillsides above a set elevation and gradient to construction, and a house built outside them can be ordered demolished. A plot reached across a neighbour’s land needs a registered servitude for the access road, not a verbal promise.

Renting out a Samui villa

Nightly letting is hotel business under the Hotel Act, unless the house is registered with the district office as a small establishment of no more than four rooms and twenty guests. Rent paid to an owner who is not tax resident carries 15 percent withholding. Thailand keeps no letting register and Samui’s small estates publish no occupancy, so this page quotes no yield; ask the seller or a manager for a year of actual statements on a comparable house.
