Koh Samui and Koh Phangan: Thailand’s Next Property Investment Story

For years, Koh Samui and Koh Phangan have been known first as lifestyle destinations: tropical islands, beach villas, boutique resorts, wellness retreats, and a slower rhythm of life that attracts visitors from all over the world. But that image is changing fast.

According to Colliers Thailand, both islands are now entering a new stage of growth, moving beyond tourism and increasingly being viewed as serious property investment destinations.

The numbers tell the story. In the first quarter of 2026, Koh Samui and Koh Phangan had 154 residential projects on the market, representing around 2,860 units and a combined investment value of more than 61.14 billion baht. That is no longer a small island market. It is a clear signal that demand, capital, and developer confidence are all moving in the same direction.

A major driver behind this growth is foreign demand. International buyers continue to look for holiday homes, long-term lifestyle investments, and income-generating assets in destinations that still feel less saturated than Phuket. Leasehold ownership structures have also become an important part of the market, giving foreign buyers more options and helping support continued activity in both the villa and condominium sectors.

Colliers compares the current growth pattern of Samui and Phangan to Phuket around five years ago. The difference, however, is that land prices on Samui and Phangan remain significantly lower than Phuket’s, which gives the islands room for further growth. Over the past one to two years, land prices have already risen sharply, but many investors still see the market as being in the early stages of its investment cycle.

The condominium sector is particularly interesting. Supply remains relatively limited compared with demand, which has resulted in strong absorption rates. This is attracting larger developers from Bangkok and other parts of Thailand, with names such as Supalai and Ornsirin Holding expected to continue expanding into the market in 2026.

But the opportunity is not without risk. As the market matures, success will depend on more than simply buying land or launching another project. Developers and investors will need to pay close attention to land title verification, infrastructure, access, location quality, pricing, target buyers, and whether the product genuinely matches market demand. In a fast-rising market, the difference between a strong investment and an overconfident one can be very thin.

What we are seeing now is the early formation of a more sophisticated island property market. Koh Samui and Koh Phangan are no longer just holiday destinations with occasional villa developments. They are becoming structured investment markets, shaped by foreign capital, rising land values, larger developers, and a growing appetite for luxury residential property.

If this momentum continues, Samui and Phangan could become Thailand’s next major international property hub — not as a copy of Phuket, but as a more boutique, lifestyle-driven alternative with its own character, constraints, and opportunities.
