The average entry price for a leasehold villa on Koh Samui in 2026 sits in the range of 8.5-22 million THB (approximately USD 235,000-610,000 at Q1 2026 rates). That is 25-40% below comparable properties in Phuket districts such as Bang Tao or Layan. The headline discount is real, but the investment calculation requires a careful look at factors that carry sharper edges on Samui than on the larger island.
Our analysts have tracked the Koh Samui market district by district since 2019. In our 2025 data sets we recorded an approximately 18% year-on-year increase in new villa project launches in Maenam and Bophut, while activity in Chaweng slowed as developers shifted toward the condominium format.
For foreign buyers, leasehold is the dominant legal structure for villa acquisition on Koh Samui. Thai law prohibits foreigners from owning land outright - freehold land title is reserved for Thai nationals. The standard arrangement is a 30-year land lease with two renewal options (up to 90 years in total), though the renewals are not guaranteed by statute and depend on the landowner's willingness to extend.
Quick answer
- Leasehold 30+30+30 years is the prevailing acquisition model for foreign villa buyers on Koh Samui - based on our estimates, it covers over 85% of villa transactions involving non-Thai purchasers
- Entry price for a 2-3 bedroom pool villa: from 8.5 million THB in Lamai and Maenam, from 14 million THB in Bophut (Fisherman's Village area)
- Net rental yield for Samui villas is estimated by our team at 4.5-6.5% per year (before income tax), varying by district and specification
- Alternative - freehold condo: entry from 3.5 million THB, simpler resale, but lower short-term rental revenue per square metre
- Samui Airport (USM), privately operated by Bangkok Airways, limits capacity to roughly 40-50 flight movements per day and keeps ticket prices 30-50% higher than equivalent routes to Phuket (HKT)
- Operating costs for a Samui villa (pool maintenance, security, garden, rental management) absorb on average 30-40% of gross rental income
Options and scenarios
How leasehold works on Koh Samui
The leasehold structure rests on a land lease agreement registered at the local Land Office. A building erected on leased land can be owned by a foreigner as a separate registered asset, but in practice the building's value is inseparable from the right to occupy the ground beneath it.
We observe two variants in the market:
- Pure leasehold - a 30-year lease registered at the Land Office, with supplementary private agreements covering the two renewal periods (30+30). Each renewal typically costs 5-15% of the land value for that period
- Thai company structure - the foreigner controls a Thai Co., Ltd. that holds freehold land title. This model carries meaningful legal risk: the Land Department has conducted active audits of nominee shareholding arrangements since 2023. We do not recommend this structure without thorough independent legal analysis
Based on our analytical work, a pure leasehold with a well-drafted agreement offers the most favourable balance of legal security and cost. The clauses that matter most are: the right to sublet, the right to transfer the lease to a third party, and a defined mechanism for adjusting the annual land rent.
Bophut and Fisherman's Village
This is the upper segment. Three-to-four bedroom sea-view villas run from 14-22 million THB in leasehold. Proximity to the international restaurant and boutique strip at Fisherman's Village supports premium nightly rates. Short-term rental occupancy reaches 65-75% in peak season (December-April), falling to 30-40% in the low season (June-October). Average nightly rates: 8,000-15,000 THB at peak.
Maenam
A quieter, family-oriented district. Two-to-three bedroom leasehold villas are priced at 8.5-14 million THB. Maenam's beach is long and flat, which appeals to families. Guest turnover is lower than Chaweng, but occupancy in the medium-term rental segment (one to three months) is more stable. Our on-the-ground monitoring confirms that Maenam is attracting a growing number of digital nomads on 30-90 day stays.
Lamai
Mid-range pricing. Two-to-three bedroom villas from 9-16 million THB. Lamai strikes a workable balance between tourist infrastructure and relative quiet. The quality of access roads to hillside villas is a recurring issue - during the rainy season (November-January) some routes become difficult to navigate. Rental yields are broadly in line with Maenam.
Chaweng
The island's highest short-term rental turnover, but the villa segment is contracting. Developers in 2025-2026 are shifting to condominiums - selling a freehold unit at 4-7 million THB is a more straightforward proposition than a villa at 12 million THB or above. New villa launches in Chaweng are rare. The existing villa stock is older (mostly built 2008-2015) and typically requires higher renovation expenditure.
Scenario 1: Leasehold villa in Maenam - holiday rental
Acquisition of a 2-bedroom pool villa for 10 million THB. Leasehold 30 years. Projected calculation:
- Gross rental income: 200 nights x 5,500 THB/night = 1,100,000 THB/year
- Operating costs (rental management at 20%, pool and garden upkeep 80,000 THB, utilities 50,000 THB, insurance 25,000 THB, minor repairs 40,000 THB) = 415,000 THB/year
- Annual land rent (typical range in Maenam: 100,000-200,000 THB) = 150,000 THB/year
- Net result before tax: 1,100,000 - 415,000 - 150,000 = 535,000 THB/year
- Net yield: 535,000 / 10,000,000 = 5.35% per year
Investors resident for tax purposes in other jurisdictions should account for their home country's treatment of foreign-source rental income, including any applicable double taxation relief under the treaty between their country of residence and Thailand.
Scenario 2: Freehold condo in Chaweng - short-term rental
Acquisition of a 35 sq m studio for 4 million THB. Full freehold ownership within the foreign ownership quota of the building. Projected calculation:
- Gross rental income: 220 nights x 2,200 THB/night = 484,000 THB/year
- Costs (common area fee 30,000 THB, management at 20%, electricity 24,000 THB, sinking fund allocation 8,000 THB) = 158,800 THB/year
- Net result: 484,000 - 158,800 = 325,200 THB/year
- Net yield: 325,200 / 4,000,000 = 8.13% per year
The percentage yield is higher, but the absolute THB return is lower. Resale is also more straightforward - freehold condos are more liquid on the secondary market than leasehold villas.
Scenario 3: Premium villa in Bophut - seasonal rental with personal use
Acquisition for 18 million THB. Personal use 60 days/year, rental for the remaining 140 nights in season.
- Gross rental income: 140 nights x 12,000 THB = 1,680,000 THB/year
- Operating costs (management, maintenance, land rent, insurance): approximately 720,000 THB/year
- Net result: 960,000 THB/year
- Net yield: 960,000 / 18,000,000 = 5.33% per year
The investor retains two months of personal use annually - the lifestyle value of that access is not captured in the financial return calculation.

Risks and mistakes
- Lease renewal risk - the 30+30 renewal options written into a private agreement do not have the force of a real property right. If the landowner dies, heirs may contest the commitment. We recommend verifying the land title (Chanote is the strongest grade) and the financial standing of the lessor before signing
- Nominee shareholding - a Thai company structure built around nominee shareholders is unlawful. The Land Department on Samui audited dozens of companies during 2024, with penalties including cancellation of land title
- Occupancy overestimation - many project brochures project 250-280 rental nights per year. In our data sets, realistic occupancy for Samui villas runs at 180-220 nights depending on district and marketing quality
- Hidden transaction costs - transfer fee (2% of registered value), stamp duty (0.5%), withholding tax, and Land Office registration fee for the lease. Total transaction costs amount to 3-6% of the purchase price
- Currency risk - over the past five years the THB has moved within a meaningful range against major currencies. Over a 10-year investment horizon a 10% shift in the exchange rate materially affects the real return measured in the investor's home currency
- Absence of professional management - a villa without a professional property manager generates costs, not returns. Management fees (15-25% of gross rental income) are a necessity, not an optional expense
- Infrastructure constraints - as detailed below, Samui's airport capacity and road network are structural limiters on rental demand that do not apply to the same degree in Phuket
Infrastructure constraints on Koh Samui
Samui Airport (USM) is privately owned by Bangkok Airways. The absence of competition on domestic routes keeps one-way fares to Bangkok at 3,500-6,500 THB, versus 1,200-2,500 THB on low-cost carriers to Phuket. Runway capacity limits total operations to roughly 40-50 movements per day. There are no direct international long-haul connections - travellers from Europe require a minimum of two connections or a stop in Bangkok.
Roads on Samui consist mainly of the two-lane ring road (Routes 4169/4170) plus a network of narrow lanes serving hillside villas. During the rainy season, washouts and minor landslips are not uncommon, affecting access to certain properties and raising private road maintenance costs.
Water and power - during the dry season (February-April) localised water supply interruptions occur. Villas with private storage tanks and filtration have an operational advantage. Power stability varies across the grid; backup UPS systems and generators are standard specification for premium villas.
Contractor availability - the island has a limited pool of construction firms with premium-segment experience. Per 2025 market estimates, build costs on Samui run 15-25% above Phuket levels, driven primarily by the cost of transporting materials by ferry from the mainland (Donsak to Nathon). Project timelines tend to run 2-4 months longer than comparable Phuket projects.
These constraints feed directly into secondary market liquidity. Lower airlift capacity translates to lower tourist volumes, which narrows the pool of potential renters and resale buyers.
FAQ
Can a foreigner own a villa outright on Koh Samui?
Foreigners cannot own land in Thailand. Since a villa is attached to land, the standard structure is a leasehold (30-year lease with renewal options). The only route to full freehold ownership available to foreigners is purchasing a condominium unit within the foreign ownership quota of a registered building.
What does a 2-3 bedroom leasehold villa on Koh Samui cost in 2026?
Based on our current data sets, prices start from approximately 8.5 million THB (roughly USD 235,000) in Maenam and Lamai for a pool villa. In Bophut, entry-level pricing begins around 14 million THB.
What is the realistic net rental yield for a Samui villa?
Based on our estimates, net yield after operating costs and before income tax runs at 4.5-6.5% per year. The key variables are occupancy rate, nightly rate achieved, and the quality of property management.
How does a pure leasehold differ from a Thai company structure?
A pure leasehold is a land lease agreement registered at the Land Office - transparent and legally compliant. A Thai company structure that relies on nominee shareholders is unlawful and subject to active scrutiny by the Land Department. We do not recommend nominee arrangements without comprehensive independent legal review.
Does Samui Airport limit the island's investment potential?
Yes, materially. The privately operated USM airport (Bangkok Airways) sustains higher fares and lower seat capacity than Phuket International Airport. This structurally limits tourist volumes and, by extension, rental occupancy rates relative to Phuket.
What are the typical annual operating costs for a Samui villa?
For a 2-3 bedroom pool villa, our team estimates annual operating costs at 400,000-600,000 THB, covering rental management, pool and garden maintenance, utilities, insurance, and minor repairs. Annual land rent is an additional line item on top of these figures.
Which Koh Samui district performs best for short-term rental?
Chaweng generates the highest guest turnover, but new villa supply there is contracting. Bophut (Fisherman's Village) commands the highest nightly rates. Maenam performs well in the medium-term rental segment (one to three months). The optimal district depends on the investor's rental strategy and personal use requirements.
How liquid is the resale market for leasehold villas on Koh Samui?
Liquidity is lower than for freehold condominiums. A buyer of a leasehold villa acquires the remaining lease term - the shorter that remaining term, the harder the resale and the lower the achievable price. Lease transfers also require the landowner's consent.
How is rental income from a Thai villa taxed for foreign investors?
Thailand levies withholding tax on rental income earned locally. Investors should verify the treatment of that income under any double taxation agreement between Thailand and their country of tax residence, and take independent tax advice before committing to an investment.
