Why this guide matters

Buying property in Thailand differs from buying in Europe — land-ownership rules, legal structures and procedures are different. We have prepared a clear guide that walks through the whole process, so you know exactly what you are buying and on what terms.

Freehold vs Leasehold

The two core structures in Thailand — and what we use at Harmony Life.

Feature	Freehold	Leasehold	At Harmony Life
What it is	Full ownership	Long-term right to use	Leasehold — right to use
For foreigners	Condominium units only (49% quota)	Widely available	Standard for our villas & apartments
Land	Share via condominium	Land leased	Land on a registered lease
Duration	Indefinite	Typically 30 years + renewals	30 years + 2×30 (per contract)
Typical use	Apartments (condominium)	Villas & houses on land	Primary structure for international investors

Ownership structure at Harmony Life

For international investors the core structure is leasehold — a long-term right to use the property under a registered lease agreement. Depending on the project, you receive a full set of documents covering your right to the property, the rules of use and your participation in the rental programme.

The document set you receive:

✓Reservation agreement
✓Main / developer agreement
✓Leasehold agreement (registered first term)
✓Rental management agreement
✓Common-area and cost regulations
✓Clear owner-use terms

In selected cases a Thai-company structure can be analysed — always with an independent lawyer. We recommend transparent solutions, compliant with Thai law and matched to the specific property type.

The buying process, step by step

A transparent path — from choosing the property to handover into rental management.

1
Choosing the property
You choose a villa or apartment and receive the full information set: location, layout, price, payment schedule, completion date and the legal model.
2
Reservation
You sign a simple reservation agreement and pay a reservation fee that takes the property off the market and locks the price.
3
Due diligence
You verify the documents — on your own or with an independent lawyer. We share land documents, permits, agreements and the schedule.
4
Main agreement
After verification you sign the main agreement: developer, leasehold and rental-management.
5
Staged payments
You pay in stages according to an individual schedule linked to construction progress.
6
Construction & updates
You receive construction-progress updates — photos and milestone reports, with a dedicated investor contact.
7
Handover
You check the finish standard, note any snags, sign the handover protocol and receive the keys and documents.
8
Rental management
If you choose the investment model, the property is taken under the team’s care and prepared for rental.

Before signing, you receive an estimated breakdown of the additional costs for the specific property. Annual local taxes are usually relatively low compared with Europe, but they depend on the property and current regulations.

Rental management

We don’t just sell property — we build an ecosystem in which your property can work for you while remaining part of a well-kept space. Rentals are handled by the local Harmony Life team on Koh Samui.

What we handle:

✓Listing preparation & presentation
✓Booking and guest handling
✓Check-in / check-out, cleaning, servicing
✓Oversight of the property’s condition
✓Reporting and settlements

Your quarterly report includes:

✓Nights booked and occupancy
✓Gross revenue and costs
✓Platform commissions
✓Net revenue and the owner’s amount

The recommended model is quarterly net settlement — after agreed operating costs and commissions are deducted, you receive a report and the amount due to the owner.

You can also use the property yourself — the terms and availability (including high season) are set out in the agreement.

Exiting the investment

An investment should have a clear entry point and a possible exit path. You can resell your rights to the property in line with the agreement — for leasehold, usually by transferring the rights under the contract.

Harmony Life can support your resale: preparing the listing and photos, presenting to buyers from our investor base, and coordinating with the lawyer and documents.

What most affects resale value:

✓Good condition & upkeep
✓Transparent legal structure
✓A rental track record
✓A recognisable project and location
✓Access to shared infrastructure

Frequently asked questions

Yes, but the structure depends on the property type. A foreigner can own a condominium unit within the foreign-quota limit. For villas and houses on land, leasehold — a long-term right to use — is most common.

As a rule, a foreigner cannot own land in Thailand directly. That is why villa projects use leasehold or other structures that require individual legal analysis.

Typically 30 years. The contract can provide for renewals of further terms, e.g. 2 × 30 years, where the project structure and documents allow. Every contract is worth checking with a lawyer.

The recommended model is quarterly net settlement. You receive a report with revenue, costs, occupancy and the amount due to the owner after agreed operating costs are deducted.

Yes. Owner-use terms are set out in the agreement — you can book stays for yourself subject to availability and any seasonal limits.

We do not communicate guaranteed income. The property can generate rental revenue, and the amount depends on occupancy, season, pricing, operating costs and market conditions.

Primarily location, finish standard, the tourist season, the view, property size, photo quality, guest reviews, market pricing, marketing, service level and access to project infrastructure.
