What are the essential steps to follow to buy a house in Chiang Mai as a foreigner?
Under Thai law, and in particular the Land Code Act B.E. 2497 (1954), foreign nationals cannot own land in Thailand, including in Chiang Mai. For this reason, anyone seeking to buy a house in Chiang Mai as a foreigner must understand that Thai law prohibits both direct and indirect land ownership. A foreigner cannot hold land title in their own name. Any residential investment must therefore rely on legally compliant alternatives.
Despite these restrictions, Thai law offers several lawful mechanisms for foreign nationals to invest in residential property. These include long-term lease arrangements governed by the Thai Civil and Commercial Code. Foreigners may also acquire condominium units under the Condominium Act B.E. 2522 (1979). In addition, they may lawfully construct residential buildings on leased land, provided that contracts clearly separate land rights from building ownership.
This article serves as a comprehensive legal guide for individuals who wish to buy a house in Chiang Mai as a foreigner. It explains each legally compliant option. It also outlines the procedural steps involved and highlights the due diligence required to secure a transaction that remains enforceable and compliant with Thai law.

Step 1: Choosing the right property in Chiang Mai is key when you decide to buy a house in Chiang Mai as a foreigner
The 30-year leasehold agreement
Foreigners cannot own land in Thailand. However, they may legally enter into a lease agreement for up to 30 years, non-renewable, as provided under the Thai Civil and Commercial Code. This lease must be formalized in writing and registered with the Land Department to be enforceable against third parties. The lease grants the foreign lessee the right to occupy and use the land for residential purposes during the lease term.
Lease contracts can require full payment at the outset or regular installments over the lease term. If you plan to buy a house in Chiang Mai as a foreigner, review whether the lessee has rights to transfer or sublease the property. These rights should be clearly stated in the agreement.
Acquiring a condominium unit in full ownership
One of the most secure and straightforward ways to buy a house in Chiang Mai as a foreigner is by purchasing a condominium unit. Under the Condominium Act B.E. 2522 (1979), foreign nationals can acquire freehold ownership of condominium units, provided the total foreign ownership does not exceed 49% of the condominium project’s floor area.
The ownership of the condominium unit must be registered at the Land Department, and the title deed will be issued in the foreign buyer’s name.
This method remains the most common legal route for foreign nationals seeking property rights in Thailand. It offers full ownership, ease of transfer, and clear protection under Thai law.
Constructing a house on leased land
Another legal alternative for foreigners is constructing a residential building on land leased for 30 years. If you decide to buy a house in Chiang Mai as a foreigner, you do not own the land but can retain ownership of the building, provided the lease agreement explicitly grants you this right.
Before construction begins, the foreign lessee must obtain a building permit in their name. The permit and any construction contracts must align with the lease terms. It is advisable for the construction agreement to clearly outline the foreigner’s rights over the building and its fate at the end of the lease term. In practice, the building may be transferred, removed, or renegotiated for continued use, depending on the lease terms.
This arrangement provides greater flexibility for foreigners who want a standalone house while complying with Thai property laws.

Step 2: Due diligence when you buy a house in Chiang Mai as a foreigner
Once you identify a suitable property or lease option, conducting due diligence is crucial to avoid legal risks. The due diligence process includes verifying land title and ownership, ensuring the property is free from encumbrances, and confirming compliance with zoning and construction regulations.
The most secure land title in Thailand is the Chanote (Nor Sor 4 Jor). It provides full ownership rights and clear land boundaries. Other titles, such as Nor Sor 3 or Nor Sor 3 Gor, offer only possessory rights and may pose legal complications. A lawyer should confirm that the seller has legitimate ownership or leasing rights over the property.
If the property is held by a company, the buyer should verify the company’s registration documents, including the Company Affidavit, shareholder list, and board resolutions authorizing the sale.
A lawyer must also investigate whether the property is free of encumbrances such as mortgages, servitudes, or litigation. If you plan to buy a house in Chiang Mai as a foreigner, verify zoning regulations, road access, and building permits if construction is involved. If the house is built on leased land, the lease must be registered and clearly outline the rights to construct, use, and transfer the building.
Step 3: Signing the reservation agreement when you buy a house in Chiang Mai as a foreigner
Once the property passes legal checks, the buyer signs a Reservation Agreement. This agreement outlines the buyer’s intent to purchase the property and reserves it for a limited time. It typically involves a reservation deposit and defines the agreed price, timeframe for signing the final contract, and penalties for withdrawal or breach. While this contract does not transfer ownership, it secures the buyer’s rights pending the final Sale and Purchase Agreement when you buy a house in Chiang Mai as a foreigner.
Step 4: Executing the Sale and Purchase Agreement (SPA) when you buy a house in Chiang Mai as a foreigner
The SPA is the principal legal document that formalizes the transaction. This contract must be written in Thai and is often accompanied by an English translation for foreign parties. It includes the identity of the parties, the purchase price, payment schedule, legal description of the property, and the allocation of tax liabilities and registration costs.
For leasehold arrangements, the SPA may also include terms regarding the construction of a house and the obligations of the lessor. Signing the SPA legally binds both parties to the transaction when you buy a house in Chiang Mai as a foreigner.
Step 5: Transferring funds from abroad
When buying a house in Chiang Mai as a foreigner, Thai law requires that all funds used in the transaction originate from outside Thailand. These funds must be converted into Thai Baht by a local bank. A Foreign Exchange Transaction Form (FET Form) is required for amounts exceeding USD 50,000.
The buyer must ensure that the name on the transfer matches the name on the SPA and land documents. This helps avoid delays or legal disputes. The form is necessary to complete the property registration and essential for repatriating funds later.
Step 6: Transfer of ownership when you buy a house in Chiang Mai as a foreigner
To complete the process of buying a house in Chiang Mai, the transfer of ownership rights must be officially registered at the Land Department. This step is essential to make the transaction legally binding when you buy a house in Chiang Mai. Both parties, or their legal representatives, must be present on the scheduled day. The Land Officer will review the documentation and record the new ownership or lease in the land registry.
The transaction becomes legally effective only after the payment of government duties. These include a transfer fee based on the appraised value, as well as other applicable taxes such as stamp duty, Specific Business Tax, or Withholding Tax, depending on the seller’s profile. The Sale and Purchase Agreement should clearly set out these amounts and their allocation. Once registration is completed and fees are paid, the legal transfer is final.
Yellow Book and Pink Card: Proof of Residence
After buying a house in Chiang Mai as a foreigner, you should apply for a Yellow Book (Tabien Baan). This household registration document proves residency and facilitates interaction with Thai authorities. However, it does not confer ownership when you buy a house in Chiang Mai.
Additionally, foreigners with a Yellow Book can obtain a Pink ID Card. This national ID simplifies interactions with local banks, hospitals, and government institutions.

While foreigners cannot legally own land in Thailand, the legal system provides safe and effective alternatives for buying a house in Chiang Mai. Through registered leases, condominium purchases, or house construction on leased land, foreigners can secure long-term residential rights.
The legal journey to buy a house in Chiang Mai as a foreigner requires diligence, legal oversight, and strict compliance with Thai laws. Every step—from property selection and due diligence to fund transfers and registration—demands professional support. With proper legal structuring, foreigners can acquire and enjoy residential property in Chiang Mai safely and legally.
