Buying in Koh Samui
How foreigners buy a pool villa on Koh Samui: how villas are held, resale versus new-build, estates and standalone homes, the checks that matter, costs and what makes a villa a good long-term buy.
In short
- Foreign buyers usually own the villa itself and hold the land on a registered 30-year lease, with a superficies so the house is legally theirs.
- Resale villas show you real condition, bills and rental history; new-builds offer a fresh lease, a warranty and payment plans.
- On an estate, check the shared roads, fees, rules and who owns the common areas.
- Have a building survey as well as legal due diligence. Tropical climate defects are common and costly.
- Price a villa on its location, view, build quality and remaining lease, not just its size.
A private pool villa is what most people picture when they think of owning on Koh Samui, and it’s the island’s most popular purchase for international buyers. Villas range from compact one-bedroom garden villas in new projects to large sea-view estates in Choeng Mon. Buying one well comes down to three things: the right structure, careful checks, and a clear view of what makes a villa hold its value. This guide covers all three.

How a foreigner holds a villa
Because foreigners can’t own land in Thailand, a villa purchase is usually structured as:
- A registered lease of the land, normally 30 years, recorded on the title deed.
- A superficies over the land, so the house and anything you build are legally yours.
- The house transferred to you, or registered in your name if it’s being built.
- A registered servitude for road access and utilities, where the access crosses other land.
See freehold vs leasehold, usufruct, superficies and servitudes and foreign property ownership.
Watch out
“Freehold villa” adverts aimed at foreigners usually mean the house is freehold and the land is leased, or the land is held by a Thai company. Ask exactly what will be registered in your name. Avoid any structure relying on Thai nominee shareholders.
Resale or new-build?
| Resale villa | New-build or off-plan villa | |
|---|---|---|
| What you see | The real villa, its condition and its bills | Plans, a show villa, the developer’s record |
| Lease | The remaining term on the existing lease | Usually a fresh 30-year lease |
| Warranty | None, unless agreed | A defects warranty period |
| Price | Market price, often negotiable | List prices; launch offers and payment plans |
| Rental | Real booking history | Projections |
| Risk | Hidden defects, lease terms | Delay, specification changes, developer risk |
See buying off-plan property and current developments.
Estate villa or standalone villa?
- Estate villas sit within a managed development with shared roads, security, landscaping and sometimes a shared pool or clubhouse. They’re easier to manage from abroad and often come with a rental programme. Check the estate fees, the rules (on renovations, letting and pets), who owns the roads, and how decisions are made.
- Standalone villas offer more privacy and control, often larger plots and no estate fees. You’ll handle maintenance, security and access yourself, and resale depends more on the individual property.
What to check on any villa
- The land title (ideally Chanote) and every right registered on it.
- The lease: remaining term, renewal wording, assignment rights and succession on death.
- A superficies covering the house, and the house being transferred into your name.
- Legal access: road frontage or a registered servitude.
- Building permit, and the villa matching the approved plans.
- Water supply, power capacity and drainage.
- A building survey: roof, waterproofing, structure, pool, electrics and retaining walls.
- Estate fees and rules, if on an estate.
- Licensing, if you plan to let it to holiday guests.
See the full list in property due diligence in Thailand.
The building survey: what tropical villas suffer from
Legal checks don’t tell you about the building. On Samui, an independent inspection often finds:
- Roof and waterproofing failures, especially on flat roofs and around skylights.
- Damp and mould from poor ventilation or drainage.
- Pool leaks and worn pumps or filters.
- Electrical work that doesn’t meet standards.
- Cracks in retaining walls on hillside plots.
- Termite damage to timber.
Use the findings to negotiate, or to plan repairs before you let the villa.
What a villa costs to buy
- The price, split between the lease and the building where relevant.
- Lease registration: 1% of the total rent plus 0.1% stamp duty.
- House transfer: 2% of the building’s appraised value, plus seller taxes.
- Superficies and servitude registration.
- Legal fees, survey and inspection.
See worked examples in property taxes and transfer fees.
What a villa costs to run
Electricity, pool and garden care, maintenance, insurance, estate fees and tax, plus management if you let it. See villa ownership and running costs.
What makes a villa a good long-term buy
| Factor | Why it matters |
|---|---|
| Location | Proximity to beaches, amenities and the airport drives both rental and resale |
| A protected view | Sea views add value only if they can’t be built out |
| Build quality | Good waterproofing, materials and design age well in the tropics |
| Practical layout | Bedrooms with their own bathrooms, good flow to the pool and outdoor living |
| Access | A safe, paved, registered road |
| Remaining lease | A long registered term supports resale |
| Rental record | Real income and reviews add value for investors |
