Economy
Koh Samui is part of the Thai economy, but its real estate market has its own dynamics. For anyone considering buying property in Koh Samui, factors such as international tourism, foreign buyer demand, land availability, infrastructure development and the quality of new supply can be more relevant than any single national economic indicator.
The Bank of Thailand forecasts economic growth of 2.3% in 2026, while also noting that growth remains uneven. This means individual sectors and regions can perform very differently from the national economy as a whole.
For Koh Samui, tourism is particularly important. Thailand remains one of Asia’s leading tourism destinations, with the Tourism Authority of Thailand targeting around 33 million international arrivals in 2026. Samui also continues to hold a strong position as a premium lifestyle destination, attracting tourists as well as buyers looking for a second home or an investment property.
Colliers data shows that demand for Koh Samui villas is largely driven by international buyers. In 2025, villa supply increased by 34% year on year, while the take-up rate improved to 71.5%. Land prices in established areas such as Chaweng–Bophut, Lamai and Maenam also remain elevated due to the limited availability of well-located land.
For investors, this matters. A growing number of new developments confirms continued interest in the island, but it also creates more competition. Simply being located in Koh Samui is no longer enough to make a property a strong investment.
In practice, it is worth looking beyond Thailand’s headline GDP growth. Location, construction and project quality, pricing relative to the local market, surrounding infrastructure, rental potential and future competition in the area all matter.
The Koh Samui real estate market is becoming more mature and more selective. Well-positioned and thoughtfully designed properties can benefit from the island’s continued popularity, while overpriced projects or properties in weaker locations may face challenges both in the rental market and at resale.
This is why investing in Thailand real estate requires more than looking at the national economy. In Koh Samui, each project should be assessed against real local demand, supply, location and the way the island is developing as a place to live, travel and invest.
