How have property prices in Koh Samui changed over the past three years?
Property prices in Koh Samui have experienced substantial appreciation since 2022, with the market recovering strongly from pandemic lows.
Average property values increased from approximately 45,000-50,000 THB per square meter in 2021 to 59,250 THB per square meter as of mid-2025, representing an 18-30% overall increase. This growth reflects the return of international tourism, limited new supply, and sustained foreign buyer interest.
Luxury beachfront villas have seen the most dramatic appreciation, with properties that sold for 40-50 million THB in 2020 now commanding 55-70 million THB—a 35-40% price surge. The annual growth rate has consistently remained between 5-10%, and market analysts expect this trend to continue at 5-7% annually through 2030.
It's something we develop in our Thailand property pack.
What are the current average prices per square meter for condos, villas, and land?
As of September 2025, property prices vary significantly by type and location within Koh Samui.
Villas average 59,250 THB per square meter, with typical listing prices ranging from 17.2 million to 30.5 million THB. However, this range extends from budget properties around 5 million THB to ultra-luxury beachfront estates exceeding 80 million THB.

How is the rental market performing in terms of occupancy rates and rental yields?
The Koh Samui rental market demonstrates strong fundamentals with improving occupancy and competitive yields for well-positioned properties.
Villa occupancy rates reached 71.5% in early 2025, reflecting robust tourism recovery and increased short-term rental demand. However, rental supply has surged by 34% year-on-year, creating more competition among property owners.
Rental yields for quality villas typically range between 6-12%, with premium locations and luxury properties during peak tourism seasons achieving the higher end of this range. Properties with professional management and modern amenities consistently outperform the market average.
Despite higher occupancy, average nightly rates decreased by 11% year-on-year in 2025 due to increased competition, highlighting the importance of proper positioning and marketing for rental properties.
Are there any major infrastructure or tourism projects planned that could impact demand?
Significant infrastructure improvements are underway that will enhance Koh Samui's accessibility and appeal to property investors.
The airport expansion project is currently in progress, designed to handle increased visitor capacity and improve connectivity to international destinations. This development is expected to boost tourism numbers and, consequently, rental property demand.
Ferry terminal upgrades are also being implemented to streamline transportation between the mainland and the island, reducing travel times and improving the overall visitor experience.
These infrastructure projects are anticipated to positively impact property values, particularly in areas with improved accessibility and those positioned to benefit from increased tourist traffic.
What government policies or regulations should investors be aware of in 2025?
Several important regulatory changes in 2025 have created new opportunities while maintaining market stability in Koh Samui.
| Policy Change | Previous Rule | Current Rule (2025) |
|---|---|---|
| Foreign Condo Ownership | 49% maximum foreign quota | 75% maximum foreign quota |
| Leasehold Terms | 30-year renewable leases | 99-year leasehold terms available |
| Development Focus | Standard building requirements | Eco-friendly development prioritized |
| Zoning Laws | Strict development limits | Maintained strict limits |
| Land Ownership | No direct foreign ownership | No change - Thai company structures required |
How easy is it for foreigners to buy and own property in Koh Samui?
Foreign property ownership in Koh Samui follows Thailand's national regulations with some specific local considerations.
Foreigners can directly purchase condominiums in their own name, benefiting from the new 75% foreign ownership quota in condo buildings. This represents a significant improvement from the previous 49% limit and opens more opportunities for international buyers.
Land and villa purchases require either long-term leasehold structures (now available for up to 99 years) or Thai company ownership structures. Professional legal advice is essential for navigating these arrangements properly.
The purchase process requires strict due diligence, proper legal representation, and careful verification of ownership documents and development permits. Working with established local real estate agents and legal professionals familiar with foreign ownership requirements is critical for successful transactions.

What are the financing and mortgage options currently available for investors?
Financing options for foreign property buyers in Koh Samui remain limited through traditional Thai banking channels.
Thai banks offer very restricted financing to foreign nationals, with strict conditions including substantial down payments (typically 50-70%), proof of local income, and extensive documentation requirements. Most international buyers find this route challenging and time-consuming.
The majority of foreign investors use cash purchases or arrange offshore financing through international banks in their home countries. Some established developers offer in-house financing or extended payment plans for off-plan projects, which can provide more flexible terms.
Developer payment plans typically allow 10-30% down payment with staged payments during construction, making luxury properties more accessible to international buyers who prefer not to tie up large amounts of capital immediately.
How do property management and maintenance costs typically compare across different property types?
Property management and maintenance costs vary significantly between different property types in Koh Samui, with luxury villas requiring substantially higher ongoing investment.
| Property Type | Annual Maintenance Cost | Management Fees |
|---|---|---|
| Luxury Beachfront Villa | 200,000-500,000+ THB | 20-30% of rental income |
| Standard Villa | 100,000-250,000 THB | 15-25% of rental income |
| High-end Condo | 50,000-120,000 THB | 10-15% of rental income |
| Standard Condo | 30,000-80,000 THB | 10-12% of rental income |
| Land (undeveloped) | 20,000-50,000 THB | Minimal management required |
What are the main risks investors should consider in the Koh Samui property market right now?
Several key risks require careful consideration when investing in Koh Samui's property market as of September 2025.
Currency fluctuation risk affects profit repatriation for foreign investors, as THB volatility can impact returns when converted back to home currencies. Legal uncertainty remains a concern, particularly for complex ownership structures and long-term lease arrangements.
The market's heavy dependence on tourism creates vulnerability to global economic downturns, travel restrictions, or shifts in tourist preferences. Potential rental oversupply in certain segments could pressure yields if new developments outpace demand growth.
Regulatory changes affecting foreign ownership, taxation, or development restrictions pose ongoing risks. Additionally, buying into poorly managed developments or working with non-compliant developers can result in significant financial losses.

Based on current data, what are the short-term and long-term outlooks for property values here?
The outlook for Koh Samui property values remains positive across both short-term and long-term horizons, supported by fundamental supply-demand dynamics.
Short-term projections for 1-2 years indicate continued price growth of 5-7% annually, driven by sustained international demand, limited new luxury supply, and infrastructure improvements. The luxury villa segment and professionally managed properties are expected to outperform the broader market.
Long-term outlook for 5-10 years shows strong potential for continued appreciation, supported by upgraded infrastructure, growing global lifestyle migration trends, and Koh Samui's limited land supply. However, this positive trajectory remains subject to macroeconomic conditions, regulatory stability, and tourism industry health.
Investment success will increasingly depend on property selection, location choice, and professional management, as market sophistication grows and competition intensifies among rental properties.
