How much does property size affect the price per square meter?
Property size has an inverse relationship with price per square meter in Koh Samui - smaller units typically command higher per-square-meter rates.
Smaller units like 1-bedroom condos, boutique land plots, and compact villas command higher per-square-meter prices due to premium locations and efficient design. Luxury beachfront condos of 50-80 square meters can reach THB 125,000-128,000 per square meter.
Larger properties including multi-bedroom villas and extensive land plots see lower per-square-meter rates but much higher total prices. A typical 250-350 square meter 3-bedroom villa averages THB 14.9 million, working out to THB 42,500-59,600 per square meter.
The sweet spot for balancing per-square-meter value with total investment often falls in the 150-250 square meter range for villas and 80-120 square meter range for condos. These sizes offer reasonable per-square-meter rates while maintaining strong rental and resale potential.
What are the total costs including fees, taxes, and legal expenses?
Total purchase costs in Koh Samui typically add 4-6% to the property's purchase price when including all fees, taxes, and legal expenses.
The transfer fee amounts to 2% of the appraised value, typically split between buyer and seller. Business tax of 3.3% applies if the seller has held the property for less than 5 years, while stamp duty of 0.5% applies for properties held over 5 years - both paid by the seller.
Legal fees vary significantly but typically range from THB 75,000-150,000 for comprehensive due diligence and registration services. These fees are essential for foreign buyers to ensure proper ownership structures and compliance with Thai property laws.
Additional costs include mortgage registration fees (1% of loan amount if financing), annual land and building taxes (relatively low), and potential agent fees (usually paid by seller). Buyers should budget an additional THB 200,000-500,000 beyond the legal minimum requirements for a smooth transaction.
Withholding and income taxes are paid by the seller and vary based on ownership history, but buyers should be aware these costs may affect negotiation dynamics.
What financing and mortgage options exist for buying property?
Several financing options are available for property purchases in Koh Samui, though requirements vary significantly for foreign buyers.
International mortgages are available through Singapore banks like UOB and Chinese banks like ICBC, offering up to 70% loan-to-value ratios with terms up to 30 years. These loans are typically denominated in SGD or USD and require either a work permit or qualifying nationality for eligibility.
Thai local lenders including MBK Guarantee and certain Thai banks offer more restrictive terms - typically 50% loan-to-value with 10-year terms - mainly available to Thai spouses or long-term residents with proper documentation.
Developer financing has become increasingly popular for off-plan and new condominium purchases, offering installment plans up to 15 years with 40-50% loan-to-value ratios. This option often provides the most accessible financing for foreign buyers.
Cash purchases remain popular, especially among expats and retirees, due to the complexity of foreign financing requirements and the negotiating power that cash offers in the Koh Samui market.
How do current prices compare to one year ago and five years ago?
Property prices in Koh Samui have shown steady appreciation over recent years, with different trajectories for various property types.
Year-on-year changes from 2024 to 2025 show villa and condo prices up 5-10% across most market segments. Interestingly, rental rates for villas dropped approximately 11% in Q1 2025, but occupancy rates increased, suggesting improved market efficiency.
Looking back five years, the market experienced significant disruption during COVID-19 with prices falling in 2020-2021, but has shown strong recovery since 2023. Overall, prices are up 10-18% compared to 2020 levels, representing substantial recovery and growth.
Apartments and condominiums have recovered fastest from the pandemic downturn, with prime beachfront areas seeing the greatest appreciation. Premium sea-view properties have significantly outperformed inland and budget segments over this period.
The recovery pattern shows that location and property quality were the key differentiators - luxury properties in prime locations recovered quickly while budget properties took longer to regain pre-pandemic values.

What are the price forecasts for the next 1, 5, and 10 years?
Property price forecasts for Koh Samui show continued appreciation across all time horizons, driven by limited supply and strong tourism fundamentals.
For the next year, industry experts expect price increases of 5-10% for popular villa and condo markets, particularly in key neighborhoods like Chaweng, Bophut, and Lamai. This growth is supported by recovering tourism and increased international interest.
The 5-year outlook projects steady appreciation tied to tourism growth, infrastructure improvements, and constrained land supply. Forecasts suggest 6-8% annual appreciation in hot spots including Lamai, Choeng Mon, and Bophut sea-view areas, outpacing Thailand's general inflation rate.
Over the next 10 years, high-quality sea-view and beach-adjacent properties are expected to significantly outpace inland and budget segments. Limited developable beachfront land and potential new zoning regulations could create supply constraints that drive premium property values higher.
Long-term investors should note that infrastructure improvements, including potential airport expansions and improved connectivity to mainland Thailand, could accelerate appreciation in currently undervalued areas.
How does Koh Samui compare to other popular resort property markets?
| Location | Avg Price/sqm | Market Characteristics |
|---|---|---|
| Koh Samui | THB 60,600 (villas) | Lower supply, premium land prices, strong luxury segment |
| Phuket | THB 62,000 (villas) | More property choices, better schools/medical facilities |
| Bali, Indonesia | USD 1,500-2,500/sqm | Lower prices, less reliable infrastructure |
| Langkawi, Malaysia | MYR 800-1,500/sqm | Tax incentives, smaller luxury market |
| Koh Phangan | THB 45,000-65,000 | Lower prices, less developed infrastructure |
What are the smartest property choices for different goals?
Your property choice in Koh Samui should align closely with your primary objectives, whether for personal use, rental income, or capital appreciation.
For full-time living, sea-view villas close to amenities in Maenam, Lamai, or Bophut offer the best combination of lifestyle quality and resale potential. These areas provide good infrastructure, dining options, and healthcare access while maintaining strong property values.
Short-term rental investors should focus on high-ROI condos or modern villas near Chaweng, Bophut, and Choeng Mon. These locations attract premium tourists and command higher nightly rates, though they require more active management and marketing.
Long-term rental properties perform best in family-oriented areas like Maenam, Bang Por, and Lamai, where lower costs, good schools, and quieter living attract expatriate families and digital nomads seeking extended stays.
For buy-and-resell strategies, beachfront or sea-view units in upcoming hot spots like Lamai or Choeng Mon offer the highest appreciation potential due to limited supply and increasing demand from both residents and investors.

What are the overall best options right now for different investment goals?
The current Koh Samui market offers distinct opportunities depending on your budget, timeline, and investment strategy.
For pure investment returns, condos or villas in Chaweng, Lamai, Bophut hills, and Choeng Mon provide the best combination of high-demand rental markets and strong appreciation potential. These areas consistently outperform other locations in both rental yields and capital growth.
Budget-conscious buyers should consider inland villas in Maenam or affordable condos in Lamai and Maenam areas. These properties offer good entry points with solid rental potential, though appreciation may be slower than premium locations.
Family buyers looking for permanent or semi-permanent residence should focus on larger villas near international schools and healthcare facilities, primarily in Maenam and Lamai areas, which offer the best quality of life for children and families.
Retirement and expat buyers benefit most from low-maintenance condos or serviced villas in easily accessible areas with good medical facilities and shopping options, avoiding the isolation of some premium hilltop locations.
For resale and flipping strategies, target hotspot developments including ocean-view condos and branded villa estates in areas with limited future supply, particularly beachfront and near-beachfront properties where development restrictions limit competition.
