The short version
- 19.8M to 23.1M THB for three sea-view villas in Maret, above Chaweng and at Bang Por, all below the Koh Samui villa median of 28M THB.
- 46 of the 48 villas and houses we list on Koh Samui are recorded with a sea view, so land, age and paperwork do more to set the price than the view does.
- Aqua Samui Villas is the resale one: built 2013, cut from 22.5M to 20M THB, about 66,700 THB per sqm against an island median of 77,000.
- A company ownership label usually means buying a Thai company’s shares, and with them its history; a registered lease of up to 30 years, or a Sap-Ing-Sith granted by the owner of Chanote land, keeps your own name on the paperwork.
Three sea-view villas joined our Koh Samui list in September, and together they make an unusually clean comparison. They are priced within 3.3M THB of one another, from 19.8M to 23.1M THB, yet they sit on three different stretches of the island’s coast and represent two quite different purchases: a finished villa with thirteen years of history behind it, and two 2026 builds whose construction stage and paperwork deserve as much attention as the view. For anyone weighing a house for sale on Koh Samui, Thailand, at around 20M THB, the useful question is what each price actually buys, and, since the island’s nominee raids in August, how a foreigner can lawfully hold one and what a "company ownership" label on a listing means for the person who signs.
Where on Koh Samui are the sea-view villas?
Almost everywhere, which is the first thing worth knowing. Of the 48 villas and houses we list on Koh Samui, 46 are recorded with a sea view, so on this island the view is close to a given and seldom a reason to pay more. What separates one villa from another is the stretch of coast it looks over, how the house sits on its plot, how old it is and what the paperwork allows you to own. The September three cover three distinct parts of the island: Oasis Villas in Maret on the south-east coast, on the Lamai side; Aqua Samui Villas above Chaweng on the hillside in Bophut sub-district, in the north-east; and Coast Breeze Residences at Bang Por on the north-west coast, in the Maenam area.
None of the three is described here as beachfront, and the distinction deserves care. The Coast Breeze developer puts its project 550 m from the sea, the Aqua Samui estate is on a hillside, and for Oasis Villas the walk to the water is a question to put to us before a viewing. A villa that looks at the sea and a villa that stands on the sand are different assets at different prices, which is why our guide explains why beachfront, beach access and sea view are three different things before anyone pays for the word.
Oasis Villas, Maret: what does 23.1M buy?
The contemporary sea-view villa at Oasis Villas is the most expensive of the three at 23.1M THB, and most of the difference is in the land. It has three bedrooms and three bathrooms in 300 sqm, exactly the floor area of the Aqua Samui villa, but it stands on a 500 sqm plot against Aqua’s 220 sqm. For 3.1M THB more than the Chaweng villa, a buyer gets 280 sqm of extra ground and a house recorded as thirteen years younger. It has its own pool and garden, and the land is recorded on a Chanote title deed.
On price per square metre it is the island’s benchmark case. At about 77,000 THB per sqm it sits on the Koh Samui villa median itself, so the price looks neither stretched nor discounted for the space. The listing records a 2026 build year and offers the villa unfurnished, which changes the arithmetic in two ways. A furnishing budget has to be added on top of 23.1M THB, and the stage of construction, the handover date and what the price includes are the first things to settle in writing. We confirm where the building stands directly with the seller, so ask us before you plan a trip to see it.
Aqua Samui Villas above Chaweng: a finished villa at 20M
The Aqua Samui Villas listing is the resale villa of the three: a 2013 house with a record you can inspect. It has three bedrooms and three bathrooms in 300 sqm and is sold fully furnished. Its price has been cut from 22.5M to 20M THB, a reduction of 2.5M THB or about 11 per cent, and at roughly 66,700 THB per sqm it is the cheapest of the three by floor area and about 13 per cent below the island median. The estate itself is well documented: Aqua Samui is a development of 47 private pool villas with panoramic views over Chaweng Beach and the Gulf of Siam, designed by the architect Gary Fell of GFab.
The trade-off is land. The recorded 300 sqm sits on a 220 sqm plot, so the house rises over a small footprint and the garden is correspondingly modest. That suits a buyer who wants the view, the pool and a house that can be locked up between visits more than one who wants a lawn. A resale villa also brings a different checklist from a new one. There is no construction risk and the view can be checked from the terrace today, but thirteen years of tropical weather call for a proper survey of the roof, the waterproofing, the pool equipment and the air-conditioning, and the estate’s service charges and maintenance record are worth reading before an offer is made. The land is recorded on a Chanote.
Coast Breeze Residences, Bang Por: 19.8M
The Coast Breeze Residences villa at Bang Por is the least expensive of the three at 19.8M THB and the only one with four bedrooms, with five bathrooms, in 272 sqm on a 387 sqm plot. It is sold fully furnished, and our listing records a clubhouse, fitness centre and tennis court alongside the villa’s private pool. At about 72,800 THB per sqm it sits between the other two, about 5 per cent below the island median. According to one agency’s project page, Coast Breeze is a development of 29 pool villas on over 17,000 sqm by Wave Real Estate Group.
It is also the clearest lesson in how to read a new project’s claims. The developer’s own website, read on 27 September 2026, sets out payment as 35 per cent on booking, 30 per cent during construction and 35 per cent on handover, puts the project 550 m from the sea and gives completion as Q2 2026. The agency page puts it 400 m from Bang Por Beach and, on the same page, gives completion as both Q2 2026 and August 2026. Both dates have now passed. A distance depends on where you measure from, but a handover date that has already slipped in print is a reason to check everything else on site and on paper. Ask for the current construction stage, the handover date written into the contract, what happens if it slips and, since our record does not yet show one, the title deed, all before a booking payment. The same questions apply to the Maret villa, and our guide to what to check on a new villa before you pay was written for Hua Hin, but its questions about payment stages, specifications and handover travel well.
How do the three compare with the rest of the island?
Set side by side, the three look like this, with the medians for the 48 villas and houses we list on Koh Samui as the benchmark.
| Villa | Area | Price | Beds / baths | Size / plot | THB per sqm | Build year |
|---|---|---|---|---|---|---|
| SV349 Oasis Villas | Maret | 23.1M THB | 3 / 3 | 300 / 500 sqm | 77,000 | 2026 |
| SV350 Aqua Samui Villas | Above Chaweng | 20M THB | 3 / 3 | 300 / 220 sqm | 66,700 | 2013 |
| SV351 Coast Breeze Residences | Bang Por | 19.8M THB | 4 / 5 | 272 / 387 sqm | 72,800 | 2026 |
| Island median, 48 villas | Koh Samui | 28M THB | – | – | 77,000 | – |
Our Koh Samui villas run from 13.5M THB (SV319) to 110M THB (SV106), with a median of 28M THB, so all three September villas sit below the middle of the island’s list, and two of them are among the 13 priced at 20M THB or less. None is above the island median of 77,000 THB per sqm either. Each of the three buys something the other two do not: land in Maret, a 2013 house at a reduced price above Chaweng, an extra bedroom at Bang Por.
A fourth option near the same price is the Sense 8 Seaview Villas project on Koh Samui, a development of sea-view pool villas with prices from 22M THB. Because it is a project listing, the price is a starting figure and what it buys varies from one villa to the next, so ask us which villas remain and what each costs before setting it against the three above. For the island as a whole, our Koh Samui real estate outlook for 2025, with its market trends and key developments, and our piece on why lower land costs made Koh Samui an opportunity in 2025 give the wider context.
How can a foreigner hold a villa on Koh Samui in 2026?
The national crackdown on nominee companies reached Koh Samui in August, when The Nation reported that officials had opened 60 cases involving 88 suspects on the island, linked to property worth about 1.2bn THB. The Department of Business Development’s Director-General drew the line plainly, as The Nation reported on 18 August: a venture genuinely funded by Thai and foreign investors, with foreigners holding no more than 49 per cent, is lawful. The checks are aimed at the Thai shareholder who never invested, and our update on the 2026 nominee crackdown covers the Hua Hin enforcement and the national rule changes behind it.
That is the context in which to read a "company ownership" label on a Samui listing: the land is held by a Thai company, and buying the villa usually means buying that company’s shares and, with them, the company’s history, including who its Thai shareholders are and whether they genuinely paid for their stake. That history is the buyer’s concern, because if a Thai shareholder turns out to be a nominee, section 36 of the Foreign Business Act makes the foreigner who allowed the arrangement liable as well as the Thai who fronted it. None of this makes a company-held villa unlawful by definition, but it moves the checking from the title deed to the company’s shareholder register, its accounts and its bank records. Our guide to buying a villa as a foreigner in 2026 gives the full answer, written for Hua Hin on the same national law.
Two other lawful routes keep your own name on the paperwork. One is a registered lease of the land for up to 30 years with the house owned separately, and our explainer on whether a Thai lease can be renewed after 30 years covers what happens when the term runs out. The other is a Sap-Ing-Sith, a registered right over a property for up to 30 years, which only a genuine owner of Chanote land can grant; where a villa’s land is leased or held by a company, that owner may not be the seller. Which route each of the three villas actually offers is something we confirm with the seller, listing by listing, before you reserve, and it is better asked first than last.
This section is general information, not legal advice. Ownership turns on the specific title, lease or company documents in front of you, so have an independent Thai property lawyer read them before you commit to any of these villas, or to any other.
