Koh Samui Property Investment in 2026: What the Market Data Actually Shows

Most people looking at Thai island property start with Phuket. The airport connections are good, the agent network is well-established, and the brand sells itself. But there’s a growing group of international buyers who look at Phuket and feel like they’ve already missed the window. They want something earlier in the cycle, less crowded, less built-up, and built around a different kind of lifestyle.

That’s the conversation Koh Samui is increasingly having with international buyers. And the numbers are starting to back it up. According to Colliers Thailand, the island’s residential market comprised 113 projects, 2,422 units, and a total investment value of approximately THB 53.2 billion as of Q1 2026. This isn’t a niche island retreat anymore. It’s a maturing market, one that’s growing on its own terms.

📌  Key Takeaways

• Koh Samui’s residential market reached approximately THB 53.2 billion in total investment value as of Q1 2026 (Colliers Thailand)

• Villas are the dominant segment — 65 projects, 749 units — driven by holiday-home demand and the short-term rental market

• Condos are scarce: just 9 projects on the island, priced from THB 60,000–80,000 per sqm, up to ~THB 200,000 per sqm for luxury — limited supply could benefit early buyers

• Foreigners can own condos freehold (49% foreign quota applies) or villas via a 30-year registered leasehold

• Bophut and Mae Nam suit long-stay buyers and families; Chaweng and Lamai lead for short-term rental yield

Koh Samui Real Estate Market at a Glance (Q1 2026)

Colliers Thailand’s Q1 2026 data gives the clearest institutional snapshot of where the market stands: 113 active residential projects, 2,422 units, and a combined investment value of approximately THB 53.2 billion.

What that headline figure doesn’t show is the composition. Unlike Phuket, where high-rise condo supply has expanded rapidly in recent years. Samui remains villa-led, a result of the island’s strict building regulations that cap height and limit development near the shore. This keeps density low, protects sightlines, and constrains supply in ways that historically support long-term land values.

Foreign buyers accounted for approximately 65% of all purchases in recent years, making Koh Samui one of the most internationally oriented property markets in Thailand. Most arrive as tourists first, return several times, and eventually buy. The decision is typically driven as much by lifestyle as by investment logic.

💡 Tip: Koh Samui’s building controls that restrict height and shoreline proximity are one of the strongest structural arguments for long-term land value. Limited supply in a market with growing international demand is a useful combination for property holders.

Three Markets in One: Villas, Condos, and Housing Estates

Koh Samui’s residential market divides into three distinct segments, each with a different buyer profile, price range, and investment logic.

Villas are Samui’s heartland. With 65 projects and nearly THB 30 billion in investment value, this is the segment driving international demand — holiday homes, private retreats, and properties running in the short-term rental market.

Condominiums are the segment to watch for buyers wanting a cleaner ownership structure. There are just nine condo projects across the entire island. Prices typically sit between THB 60,000 and THB 80,000 per sqm, with luxury developments reaching approximately THB 200,000 per sqm. That scarcity creates a very different supply-demand picture from Phuket, where condo units are far more abundant. See condos for sale in Koh Samui for current listings.

Housing estates serve a less-discussed but genuinely significant buyer group: families, retirees, and long-stay residents who want a proper home rather than a resort-style property. At 39 projects and THB 17.3 billion in combined value, this is a larger segment of the market than most investors realise.

Where to Buy: Koh Samui’s Key Areas

The island splits naturally into two main corridors with different characters, prices, and buyer profiles. Our guide to the best areas to buy property in Koh Samui covers this in depth, but here’s the short version:

Chaweng Beach is the island’s main commercial and tourism strip, the obvious anchor for anyone whose investment thesis relies on tourist occupancy. It’s busier, pricier, and more competitive for bookings, but the rental demand is real and well-established.

Bophut and its Fisherman’s Village area have become the destination of choice for buyers who want a lifestyle without the noise: boutique restaurants, a weekly walking market, and a calmer beach attract remote workers and long-stay residents. Mae Nam, further west, is quieter. Great for families, with calmer seas and the Santiburi golf course nearby.

Choeng Mon and Plai Laem in the northeast sit closest to Samui Airport and deliver some of the island’s best beaches and views. New boutique developments and rising prices here are among the clearest appreciation signals on the island right now.

⚠️ Note: Thai law guarantees public access to all beaches. Beachfront property gives you direct, convenient access to the sea, not a private beach. This applies throughout Thailand, including Koh Samui.

Foreign Ownership: What You Can (and Can’t) Buy

Foreigners cannot own land in Thailand. But there are clear, well-established routes to owning property here legally and securely.

Freehold Condo

Foreigners can own condo units outright under Thai law, provided total foreign ownership in the building stays below 49% of total units. You’ll need a Foreign Exchange Transaction (FET) certificate proving the purchase funds were transferred from overseas. Keep this document carefully, as you’ll need it if you sell and want to repatriate your money.

Leasehold Villa

Since foreigners can’t own land, most villa purchases in Koh Samui use a 30-year registered leasehold, often structured with renewal options for an effective combined term of up to 90 years. When set up correctly — on a Chanote title, with an independent lawyer reviewing the lease terms — this gives buyers strong long-term security.

Thai Company Structure

Some buyers use a Thai limited company to hold land and property titles. This gives more control over the asset but requires proper legal setup and ongoing compliance obligations. It’s a legitimate route but not a DIY arrangement.

Transfer costs to budget for:

• Transfer fee: 2% of the appraised value

• Specific Business Tax: 3.3% (applies if the seller has owned the property for under five years)

• Stamp duty: 0.5% (applies instead of SBT if held five years or more)

• Withholding tax: varies; individuals pay progressive rates based on appraised value and ownership duration

⚠️ Note: Always appoint your own independent Thai lawyer, not the seller’s. For title and registration guidance, see the Land Department of Thailand. For tax details, see the Revenue Department of Thailand.
