Koh Samui’s real estate market in 2026

General trends in the Koh Samui real estate market

Koh Samui’s real estate market continues to grow moderately but steadily in 2026, with strong demand for villas and an increasing supply of condominiums. Luxury real estate still dominates the market, especially beachfront properties with panoramic views over the Gulf of Thailand, while modern condos and apartments are gaining in popularity.

Several factors explain this dynamic:

• A resurgence in international tourism, which keeps up demand for short-term rentals.
• Growing demand for comfortable living spaces for digital nomads, retirees and expatriate families.
• Consolidated infrastructure, particularly around the international airport and the island’s main roads.

Koh Samui real estate prices in 2026

Villas

Villas remain the dominant market segment, accounting for a majority of sales, mainly of detached villas or family homes.

Average villa prices vary significantly according to location, quality of construction and proximity to the sea. For example:

• Investors can turn to new villas, off-plan, in subdivisions around Lamai, between 5M THB and 7M THB for two- to three-bedroom units
• You will find completed villas in attractive areas at around 10 – 15M THB for villas with swimming pools and views of the hills.
• Top-of-the-range villas and beachfront properties command significantly higher prices.

Condos and apartments

Condominiums on Koh Samui are fewer in number than villas, but are an attractive entry option for foreign investors thanks to more affordable prices and the possibility of buying freehold.

Examples of prices observed in 2026 :

• One-bedroom apartments with sea view: ~5.9M THB (~$177,000)
• Two-bedroom condos: often between ~10M THB and ~13M THB depending on location and quality

Rental yield and return on investment

One of the strengths of the Koh Samui real estate market is its attractive rental yields. Yields can vary between 4% and 10% per year, depending on the type of property and rental management.

Well-located luxury villas, often operated on tourist rental platforms, can generate significantly higher revenues than standard properties, especially during the peak tourist season.

2026 outlook: opportunities and risks

Opportunities

• Stable price growth of around 5% to 7% per year expected in the most attractive areas, driven by international demand.
• Diversification of the offering, with eco-responsible projects and modern villas.
• Increased demand for high-end properties managed by a professional local management company.

Risks

• Competitive pressure on rental income, particularly due to increased supply.
• Be careful to choose a villa and a professional manager who can generate an income that is both attractive and realistic. Differentiate between gross and net income.

Conclusion

In 2026, Koh Samui’s real estate market remains attractive and dynamic, combining a strong tourism recovery, a diversified offer of properties and competitive rental yields. Prestigious villas and freehold condominiums are the focus of international investors’ attention, while the island continues to offer a sought-after tropical living environment.
