If you're deciding between investing in property in Koh Samui or Phuket, this quick comparison breaks down the key differences. We’ll look at pricing, investment potential, and the types of properties available to help you make an informed decision based on your goals.

Property Prices and Value for Money

At the lower end of both markets, pricing is quite similar. Entry-level apartments can be found from around 1.8 million THB, while smaller villas typically start at 5 million THB. Garden villas with private pools often start from about $250,000 USD, and sea-view properties from roughly $550,000 USD. However, Phuket tends to be priced slightly higher overall. That’s due to its more developed infrastructure, mature real estate market, and higher land costs. In the luxury space, Koh Samui villas can reach up to $8-10 million USD, while in Phuket, oceanfront estates have been known to sell for $25 million or more, particularly on the west coast.
Phuket also offers a broader range of freehold condominiums, including high-end, branded units tied to international hotels. Koh Samui, by contrast, has fewer freehold options, particularly at the high end, with most condos aimed at the entry-to-mid market.

Real Estate Investment Potential

Phuket’s property market is well established, with experienced developers and a solid infrastructure in place. It’s often seen as a safer bet for buyers seeking long-term stability and rental income potential, especially in high-demand tourist areas. Koh Samui property for sale offers a more speculative upside, especially in early-stage projects. The island is still developing, and land prices are generally lower, which means there’s more room for growth. However, this also brings risk: some developers are newer or underfunded, and many projects rely on off-plan sales. Buyers need to do their homework.
Both islands can offer good rental returns, but Phuket has the advantage of stronger tourism volume and a more mature short-term rental ecosystem.

Choice of Properties

Phuket has many luxury branded property options, from projects like Laguna Lakeside to newer launches like The Gardens of Eden. These are often managed by hotel brands and include resort-style services. Koh Samui has just one true branded residence: The Estates by Four Seasons, which is ultra high-end and has been established for years.
Phuket offers a wide variety of foreigner-friendly condos, thanks to Thailand’s condo ownership laws. These freehold units appeal to overseas buyers who want full legal ownership. In Koh Samui, there are only a few freehold projects available - like the newer Anava development in Bang Rak. Most condos in Samui are leasehold or use company holding structures

Lifestyle Considerations

When it comes to lifestyle, the two islands offer very different experiences. Phuket is generally better suited to families and professionals, with international schools, major hospitals, shopping centres, golf courses, and direct flights to Europe and Asia. It feels more connected and convenient for long-term living. Koh Samui, on the other hand, offers a slower pace and more laid-back feel. With no bridge to the mainland, it has a more genuine island atmosphere, which appeals to retirees and buyers seeking peace and tropical charm over urban amenities.

Final Thoughts

Phuket offers broader choice, stronger infrastructure, and a lower-risk profile for investors, especially those looking for freehold ownership or high-end branded villas. Koh Samui is more boutique and potentially more rewarding for those willing to take a calculated risk.
