Buying a villa on Koh Samui
Koh Samui attracts foreigners seeking island villas, but direct land freehold is prohibited for most foreign buyers. Practical ownership runs through registered leasehold, superficies, or condominium stock, not nominee companies.
At Thai Visa Centre in Bangkok, we help expats align immigration, banking, and property plans. This guide covers ownership structures, resale versus off-plan risks, and the full purchase workflow for June 2026. Start with our house buying guide and property hub.

Building rights via leasehold or superficies on Thai-owned land.

Ownership structures on Samui
Island villa marketing often blurs legal categories. The table below maps what you actually hold under Thai law. Always verify registered documents at the Department of Lands, not sales brochures alone.
| Structure | What you hold |
|---|---|
| Leasehold villa | 30-year registered lease plus structure rights on Thai-owned land |
| Freehold villa with land lease | Building registered in your name while land is leased separately |
| Superficies | Right to own structure on another person land for agreed term |
| Thai company | Only with legitimate business activity. Nominee shareholders are illegal. |
Existing, new, or off-plan?
Each purchase type carries different risk profiles on Koh Samui. Resale offers immediate occupancy. New completion adds developer warranty. Off-plan demands the strongest contract review and milestone-based payments.
| Purchase type | Key considerations |
|---|---|
| Resale villa | Immediate use but verify remaining lease term, maintenance, and encumbrances |
| New completion | Developer warranty but premium pricing and limited negotiation room |
| Off-plan project | Staged payments. EIA approval and developer track record are critical. |
| Condo alternative | Foreign freehold within 49% quota if island condo stock suits your needs |

Purchase workflow
Follow this sequence from first viewing to registered lease or superficies. Transfers complete at the Surat Thani provincial Land Office branch serving Koh Samui.
Agent shortlist and viewing
Tour multiple areas and compare lease terms, not only finishes. Ask for registered lease copies before emotional commitment.
Lawyer title and lease review
Independent counsel reviews title deed, lease registration, renewal clauses, and seller identity before any deposit.
FET remittance if applicable
Condo freehold requires foreign currency inward remittance. Leasehold villa purchases may still need clear funding documentation.
SPA signing and payment schedule
Execute sale and purchase agreement after contract review. Tie payments to registration milestones, not marketing promises.
Land Office registration
Register lease or superficies at Surat Thani Land Office. Unregistered agreements do not protect your long-term interest.
Utilities and house book transfer
Transfer electricity, water, and local registrations. Confirm juristic or management company handover for estate villas.
Areas to research on Koh Samui
Location affects lease value, rental demand, and daily lifestyle. Compare multiple zones before committing to a single developer or agent shortlist.
- Chaweng: central, busy, strong rental demand but higher noise levels
- Lamai: family-friendly beaches with mixed resale and new villa stock
- Bophut and Fisherman Village: boutique feel with restaurant and marina access
- Nathon: local commercial hub with ferry links to mainland Surat Thani
- Choeng Mon and Plai Laem: upscale residential zones popular with long-stay expats
- Verify planned infrastructure. New roads and airport expansion affect noise and access.
Transfer taxes and fees
Lease registration and building transfer trigger specific fees and taxes. Budget beyond the headline price. See our transfer tax guide for allocation between buyer and seller.
Common mistakes foreigners make
These errors appear repeatedly in Koh Samui property disputes involving foreign buyers. Most are preventable with early lawyer engagement and independent title search before any deposit.
- Assuming villa marketing equals land ownership. Most island villas are leasehold, not freehold land.
- Trusting verbal 90-year lease promises without registered renewal clauses reviewed by counsel.
- Using nominee Thai company structures to hold land. This is illegal and agreements are unenforceable.
- Paying large off-plan deposits without EIA confirmation and developer licence verification.
- Skipping independent lawyer review because the agent also offers in-house legal services.
Frequently asked questions
General answers for expats buying island property in Thailand. This is orientation, not legal advice for your specific transaction.
Q:Can foreigners own land on Koh Samui?
A:Not directly. Land Code restrictions prohibit most foreign land freehold. Compliant paths are registered leasehold, superficies, or condominium freehold within the 49% foreign quota.
Q:Do I need a lawyer for a Samui villa purchase?
A:Yes. Lease renewal clauses, company structures, and title encumbrances are where island disputes start. Hire independent counsel before paying any deposit.
Q:What is the difference between leasehold and freehold villa marketing?
A:Freehold villa with land lease means you may own the building but lease the land. True land freehold for foreigners is generally unavailable. Read registered documents, not brochures.
Q:Is off-plan villa purchase safe on Samui?
A:Only with strong contract protections. Verify environmental impact assessment, building permits, and developer completion history. Tie payments to measurable milestones.
Q:Can I finance a Koh Samui villa locally?
A:Thai bank mortgages for foreigners on leasehold villas are extremely rare. Expect cash purchase or offshore financing arranged before signing.
Q:Which Land Office handles Samui registration?
A:Koh Samui falls under Surat Thani provincial Land Office jurisdiction. Your lawyer confirms the correct branch and registration category for lease or superficies.
Q:Does buying a villa help my Thai visa?
A:No. Property ownership and immigration status are separate. Plan retirement, Elite, or other long-stay visa tracks independently from villa purchase.
Q:Should I consider a condo instead of a villa?
A:If foreign freehold title in your own name is the priority, registered condominiums under the Condominium Act may suit better than leasehold villas. Compare both paths on our property hub.
