A Secure Purchasing Process

All properties we offer come from fully vetted developers. We partner exclusively with experienced companies that have a proven construction track record on the market and maintain full legal compliance regarding ownership structures within their Thai companies. We verify the land lease history, ensure there are no building restrictions on the plot, check project approvals at the Land Office, confirm compliance with the island's zoning regulations, and review the contracts between the developer and the landowner. We do not list any projects for sale unless their contracts have been strictly audited by us to ensure they include clauses that protect our clients.

    Consultation & Property Matching

    We select a project perfectly tailored to your budget and investment goals.

  3. Step 03

    Land Due Diligence

    A lawyer verifies the legal status of the land and its lease history.

  4. Step 04

    Signing the Principal Agreements

Frequently Asked Questions (FAQ)

Do I have to be in Thailand personally to buy a property?

No, the entire property purchasing process on Koh Samui can be conducted 100% remotely from your country. The vast majority of our clients complete their transactions without ever needing to travel to the island. As part of our service, we provide detailed video recordings of the plot, construction updates from the developer, and comprehensive neighborhood overviews. All key contracts are sent securely via courier, and land verification is conducted with the participation of legal experts. The final handover of the completed building can also be done via a video conference with our team.

Can I legally buy property in Thailand as a foreigner?

Yes, a foreigner can fully and legally own property in Thailand using secure, proven legal structures. The purchase of a detached villa is based on two key documents: a construction contract, which grants you 100% ownership of the building, and a land lease agreement with a Thai landowner. The properties we offer are sold exclusively with mandatory lease registration at the government Land Office. This guarantees 30 years of ironclad, unchangeable lease conditions backed by an official government deed, which remains valid even in the event of the landowner's death.

What exactly is a 30-year land lease, and is it a safe solution?

A land lease (leasehold) registered at the government Land Office is the safest form of legal investment protection for a foreigner in Thailand. This system separates the ownership of the building (which the investor owns 100% based on the construction contract) from the right to use the land. The lease agreement, registered at the Land Office, guarantees strict terms for 30 years that remain binding and unchangeable, regardless of a change in land ownership or the owner's death. Legally, a foreigner can renew the land lease twice, totaling 90 years of usage. Furthermore, we strongly advise against the illegal practice of setting up proxy Thai companies, relying exclusively on transparent, official, and secure legal frameworks. Upon resale to a new owner, the 30-year lease period resets. In the case of donation or inheritance, the existing lease term continues.

How does resale and inheritance of property work in Thailand?

The sale of a property and its transfer to loved ones are fully secured, and we introduce the appropriate clauses protecting the investor's interests into the contracts at the very beginning of our cooperation. A villa can be resold at any time without the landowner's consent, and the new buyer receives a full reset of the lease period for another 90 years (3x 30 years). In the case of inheritance, all property rights pass to the designated heirs. Note, however, that during inheritance or donation, the lease years do not reset; the current agreement's timeline simply continues. In the contracts our clients sign, we proactively ensure that clauses regarding sale, donation, and inheritance are structured to protect the client, which is not a common practice in standard developer contracts and requires close attention.

What is the process for signing contracts and making bank transfers?

The entire administrative and financial process of buying a property is organized so that the investor can handle it efficiently from its country. The transaction requires signing three agreements: the reservation agreement (handled via scans), and the construction and lease agreements, the originals of which are sent via courier for signature and subsequent registration at the Thai Land Office (usually at the end of construction). Payments and international transfers are most commonly made in US Dollars (USD). Alternatively, you can use international payment platforms such as Revolut or Wise.

Do you offer completed villas on the secondary market?

The secondary market on Koh Samui is extremely small because the island's dynamic construction boom occurred mostly after the COVID-19 pandemic. Therefore, new projects make up the vast majority of available properties. We strongly advise against buying older properties from uncertain sources due to the high risk of hidden structural defects, as well as the unpredictable costs and time required for renovations. We focus primarily on the primary market from fully vetted developers. The only exceptions on the secondary market are freshly built, newly completed villas being resold by the developers we have already verified, which guarantees high quality and immediate handover.

Show all questions (+6) Collapse questions
How do you verify the developers you work with?

We select developers based on uncompromising security standards and a rigorous legal and structural analysis. We verify the developer's track record, the build quality of their previous projects, and their reputation on the local market. We thoroughly examine the legal structure (the composition of the Thai company, including physically meeting the Thai investors and partners) and land ownership. We also confirm that the project is approved by the Land Office before sales begin, ensuring building permits are obtained without issue (including zoning compliance on the island). Furthermore, we inspect the building materials used to ensure the structures are solid and durable. We approach every single project with the same meticulous scrutiny as if we were buying the property with our own money.

How is rental income tax settled in Thailand?

The tax settlement for rental income depends on the legal entity used for the purchase, though buying as a private individual is the most popular and optimal choice. Thailand has two main taxes for this: a Withholding Tax collected monthly, and an annual Personal Income Tax. The monthly advance payments are deducted from the final annual tax, which is progressive and accounts for the investor's individual deductions. For example, the estimated effective tax rate for a one-bedroom villa could be around 12%, and for a three-bedroom villa, it could be approximately 15%. However, this heavily depends on the investor's individual situation, applicable deductions, and villa maintenance costs.

Is an estimated ROI of 10-15+% realistic?

An estimated ROI of 10-15+% is based on current market realities, the results achieved by our clients, and our own investment experience. When calculating the projected ROI, we factor in all operational costs, including property management (20%), cleaning, pool and garden maintenance, pest control, insurance, and utilities. The high return rates on Koh Samui stem from the fact that property purchase prices are even up to twice as low as in Phuket, while short-term rental rates remain comparable, driven by high demand from affluent tourists.

What exactly determines the final ROI on Koh Samui?

The ROI is the result of several key factors, and the most expensive property does not always yield the highest percentage return. Location is fundamental: properties within walking distance to the beach or offering sea views command significantly higher daily rental rates. The standard of finishing and furnishings is also crucial, though excessive spending on ultra-luxury details can drive up the initial cost and lower the overall yield percentage. Another important variable in the calculation is the cost of the land lease, which varies depending on the prestige of that specific part of the island.

Can I live in Thailand permanently or spend entire winters there?

Yes, you can live in Thailand year-round or spend several months there during the winter by utilizing the appropriate visa options. For short stays, you enter using an online form (ETA/TDAC). You should always check current regulations on how long you can stay and extend, as this changes dynamically. For longer or permanent stays, long-term visas are available. The most popular is the 5-year DTV (Destination Thailand Visa) designed for digital nomads, entrepreneurs, and remote workers, which is obtained based on income documentation. For those over 50, the Retirement Visa is an ideal solution, allowing for a comfortable and legal life in a country where the cost of living is significantly lower than in Europe or USA. There are many more visa options available, so it is always worth analyzing your specific situation with a specialized visa agency.

How does property management work?

We recommend a hand-picked property management agency owned by a European professional with over 11 years of experience in the hospitality industry. This agency provides comprehensive, end-to-end service: from listing your property on booking platforms and acquiring guests, to managing check-ins and check-outs, cleaning, pool and garden maintenance, pest control, insurance coordination, internet, handling minor and major repairs, paying local bills, delivering tax documents to the accounting office, and providing you with monthly P&L (Profit & Loss) reports.
