The average leasehold villa price on Koh Samui in Q1 2026 sits in the range of 8.5-22 million THB, depending on district and finish quality. That is a meaningful discount relative to comparable stock on Phuket's west coast, where the equivalent segment starts at 15-18 million THB. Our analysts monitor both islands on the ground, and the breakdown below examines the leasehold villa model district by district.
A 30-year leasehold (with contractual renewal options structured as 30+30+30 years, but without statutory protection) remains the most common land-control mechanism available to foreign buyers on Koh Samui. The alternative - a Thai company structure - carries material risk related to nominee shareholding scrutiny. Per Thailand Land Department data as of 2025, such scrutiny on Samui intensified by more than 20% year-on-year. We recommend independent legal advice before considering that route.
Quick answer
- 30-year leasehold is the dominant acquisition model for foreign villa buyers on Koh Samui; registration is filed at the Land Office and attracts a registration fee of approximately 1.1% of the lease value
- Entry-level ticket for a 2-3 bedroom leasehold villa: 8.5-14 million THB in Maenam and Lamai; 14-22 million THB in Bophut and the Fisherman's Village corridor
- Premium short-term rental rates for a 3-bedroom villa with private pool during high season (December-March): 6,000-12,000 THB per night, depending on location
- Island-wide average annual villa occupancy: 55-65%, based on our estimates derived from booking platform data as of 2025
- Operating costs (property management, pool maintenance, security, insurance): 15-22% of gross rental income per year
- Samui Airport (USM) is served exclusively by Bangkok Airways, pushing domestic one-way fares to 3,500-6,500 THB and capping annual throughput at approximately 1 million passengers - a structural constraint relative to Phuket
Options and scenarios
Scenario A - Bophut and Fisherman's Village
Bophut represents the top of the villa market on the island. Based on our on-the-ground verification, new projects near Fisherman's Village are pricing 3-bedroom pool villas in the 16-22 million THB range on a 30-year leasehold. Land in this corridor transacted at 25,000-45,000 THB per talang wah in 2025. Premium tenants - couples and higher-budget remote workers - are paying 9,000-12,000 THB per night at peak season.
Illustrative calculation for a 3-bedroom villa in Bophut (leasehold, 18 million THB):
- Gross annual revenue: average rate 7,500 THB per night x 60% occupancy x 365 days = 1,642,500 THB
- Property management fee (20% of gross): 328,500 THB
- Maintenance - pool, garden, minor repairs, insurance: 120,000 THB per year
- Rental income tax (estimated; structure depends on legal form): approximately 80,000 THB
- Net result: approximately 1,114,000 THB per year, implying a net yield of approximately 6.2% on the leasehold purchase price
Scenario B - Maenam
Maenam draws families and longer-stay tenants. Leasehold villa prices for 2-3 bedroom units range from 8.5-13 million THB. Short-term rental rates are lower (4,500-7,000 THB per night), but so are operating costs - the location is less demanding in terms of guest-service standards.
For a villa purchased at 10 million THB, with gross annual revenue of approximately 1,050,000 THB (average rate 4,800 THB, 60% occupancy) and total costs of approximately 380,000 THB, the net result is around 670,000 THB, translating to a net yield of 6.7%. The higher yield relative to Bophut reflects the proportionally lower entry ticket.
Scenario C - Lamai
Lamai sits in the middle of the pricing range. Leasehold villas with 2-3 bedrooms are priced at 9-15 million THB. The tenant mix is varied - budget-to-mid-market visitors. Based on our estimates, 2025 occupancy in Lamai ran at approximately 55%, slightly below the island average. Modelled net yields: 5.5-6.0%.
Scenario D - Chaweng (villa or condominium)
Chaweng has the highest short-term rental turnover on the island, but also the most noise and the sharpest hotel competition on pricing. Leasehold villas are priced at 10-18 million THB. A structurally distinct alternative here is a freehold condominium - the only form of direct land-and-building ownership available to foreign nationals in Thailand - with studio and 1-bedroom units in the 3-6 million THB range, occupancy of 65-70%, and nightly rates of 2,000-4,000 THB. Resale of a freehold condo is legally simpler: the title deed is held directly by the foreign buyer, eliminating leasehold renewal risk.

Risks and mistakes
Leasehold renewal is not legally guaranteed. The 30+30+30 structure in a contract with the landowner is a contractual obligation only. If the landowner dies or becomes insolvent, heirs are not statutorily obligated to honour renewal terms. Our analysts have tracked at least a dozen situations on Samui between 2024 and 2025 in which a new landowner contested renewal conditions.
Samui Airport as a structural bottleneck. USM is a private airport operated by Bangkok Airways. The absence of competing carriers means a Bangkok-Samui one-way fare runs 3,500-6,500 THB, compared with 1,200-2,500 THB on Bangkok-Phuket via low-cost carriers. This measurably suppresses inbound tourist volumes relative to Phuket and feeds through into rental demand.
Water and power infrastructure. During the dry season (February-April), water supply interruptions occur on elevated terrain in Maenam and Lamai. Installing a retention tank and pump costs 150,000-300,000 THB. Power outages are more frequent than on Phuket; investors should budget for a generator or UPS system from the outset.
Construction costs. Fewer building contractors operate on Samui than on Phuket. Based on our estimates as of 2026, villa construction costs per square metre on Samui run 10-18% above comparable Phuket-standard builds, primarily because of ferry-freight costs for materials from the mainland and a smaller pool of skilled crews.
Common mistake - skipping the title deed audit. Some land parcels on Samui still carry ambiguous ownership chains. The critical distinction is Chanote (full land title, the only document that confers unambiguous ownership rights) versus Nor Sor 3 Gor (a lesser document). Our team verifies title at the Land Office before making any recommendation.
Common mistake - projecting returns on peak-season rates only. Low season (May-October) occupancy for villas drops to 30-40% and nightly rates fall 30-50% from peak. Financial planning must be anchored to the annual average occupancy of 55-65%, not high-season figures.
FAQ
Can a foreign national own a villa on Koh Samui outright?
Foreign nationals cannot own land in Thailand. They can hold the structure of a building on leased land via a 30-year leasehold registered at the Land Office. A Thai company structure is sometimes used as an alternative, but it carries nominee shareholding scrutiny risk and requires independent legal assessment.
What does a leasehold villa on Koh Samui cost in 2026?
Based on Q1 2026 transaction data in our tracking set, a 2-3 bedroom pool villa ranges from approximately 8.5 million THB in Maenam to 22 million THB in Bophut. Converted at the indicative rate of 0.113 PLN/THB, that is roughly 960,000 PLN to 2.5 million PLN.
What is the realistic net rental yield from a Koh Samui villa?
Based on our estimates, net yields (after management fees, maintenance and tax) run at 5.5-7.0% per year, depending on district and management quality. Maenam tends to produce the highest yields relative to entry price due to the lower acquisition cost.
What is the difference between leasehold and freehold on Koh Samui?
Leasehold is a land-use right for 30 years, with contractual (not statutory) renewal options. Freehold for foreign nationals applies exclusively to condominium units, where foreigners may own up to 49% of total building floor area. Freehold delivers a clean title deed and is simpler to resell.
Does Samui Airport constrain the property market?
It does. USM is a private airport with a single dominant carrier, which limits annual passenger throughput to approximately 1 million. Phuket International Airport (HKT) handled approximately 9.5 million passengers in 2025. The gap in connectivity translates directly into lower rental demand pressure on Samui - a factor investors should price into their return assumptions.
How does villa rental seasonality look on Koh Samui?
High season (December-March): villa occupancy reaches 75-90%. Shoulder season (April-May, November): 40-55%. Low season (June-October): 25-40%. Annual average sits at 55-65% and should be used as the base case in any financial model.
What are the recurring operating costs for a Samui villa?
Main line items: property management (15-20% of gross revenue), pool maintenance (4,000-8,000 THB per month), garden and pest control (3,000-6,000 THB per month), building insurance (15,000-30,000 THB per year), and ongoing repairs. In aggregate: 15-22% of gross rental revenue per year.
How does Koh Samui compare to Phuket as an investment destination?
Samui offers lower entry prices and less supply competition, but weaker air connectivity and older infrastructure. Phuket has an international airport, lower domestic airfares, a deeper rental market and higher resale liquidity. For investors working with budgets below 10 million THB, Samui can produce a higher net yield; above that threshold, Phuket generally offers better liquidity and exit optionality.
What is required to transfer purchase funds from abroad into Thailand?
An international SWIFT transfer to a Thai bank account typically clears in 2-4 business days. For freehold condominium purchases, the receiving Thai bank issues a Foreign Exchange Transaction Form (FETF), which is required for Land Office registration. For leasehold villa transactions, the FETF is not mandatory for registration, though individual banks may still request it.
What taxes apply to rental income from a Koh Samui villa?
In Thailand, rental income is subject to personal income tax at progressive rates of 0-35%. Tax residents of other countries are generally obligated to declare worldwide income in their country of residence, subject to the terms of any applicable double-taxation agreement with Thailand. We recommend consulting a tax adviser familiar with cross-border income before structuring the purchase.
