Steps to Buy a Condo in Thailand as a Foreigner (2026)
By THAI.ESTATE Editorial Team14 min read
Buying a condo in Thailand as a foreigner is legally possible, fully documented, and repeatable - but only if you follow the correct sequence. The Condominium Act (B.E. 2522, as amended) allows foreign nationals to own up to 49 percent of the total unit area in any registered condominium building, in freehold, in their own name. That ownership is real and transferable. The process has seven main steps, each with its own documents, costs, and risks.
This guide walks you through every step in order: reservation, due diligence, sale and purchase agreement, international funds transfer with the FET form, Land Office registration, and handover. Where a step can be done remotely using a power of attorney, that is noted. Costs below are indicative figures as of 2026 and marked as such.
Quick answer
- Foreign freehold condo ownership is legal under the Condominium Act: you can own up to 49% of total sellable area in a project, in your name
- The FET form (Foreign Exchange Transaction form, issued by a Thai bank) is mandatory for registration and for resale - a wrong transfer reference on your inward remittance is one of the most common and expensive errors
- Total transaction costs at the Land Office are typically 2-6% of the registered price, split between buyer and seller by negotiation
- Timeline: off-plan purchase from reservation to key handover: 18-36 months typical; resale condo: 30-90 days from offer to title transfer
- A power of attorney allows a trusted Thai representative to attend the Land Office on your behalf - useful for remote buyers
- Due diligence documents you must demand: chanote title deed copy, developer company affidavit (current, not older than 3 months), EIA approval letter, and building permit for off-plan projects
Options and scenarios
Your buying path depends on two main variables: whether the unit is off-plan (under construction) or resale (completed), and whether you are physically present in Thailand or buying remotely.
Off-plan condo purchase
You sign a reservation agreement and pay a booking fee (typically THB 50,000-200,000, indicative). The developer then issues a sale and purchase agreement (SPA) within 30 days. Payments follow a construction-linked schedule: for example, 20% on contract, 20% at foundation completion, 20% at structural completion, 10% at fit-out, and 30% at transfer. These percentages vary by developer.
Construction-linked payment schedules are the main financial protection mechanism in Thailand - they replace the concept of holding funds in a neutral account. You release each tranche only when a defined construction milestone is reached and documented. You should verify each milestone yourself or through a local representative before paying.
Off-plan buyers must demand: a copy of the land title deed (chanote) for the project plot, the EIA (Environmental Impact Assessment) approval letter from the Ministry of Natural Resources and Environment, the building permit issued by the relevant local authority, and a current company affidavit of the developer (obtained from the Department of Business Development, not older than 3 months at the time of signing). Without these four documents, do not sign.
Resale condo purchase
A resale unit is completed and physically inspectable. After agreeing on a price, you sign a reservation form and pay a deposit (typically 1-3% of the price, indicative). Due diligence runs concurrently. The SPA follows within 14-30 days. Transfer at the Land Office typically happens 30-60 days after the SPA.
For resale, additional checks include: confirming the unit is within the 49% foreign quota at the condominium juristic person office (the juristic person is the legally registered management entity for the building), verifying no outstanding common area fees or sinking fund debts (a sinking fund is a one-time capital reserve paid at purchase, typically THB 400-700 per sqm, indicative), and checking for any registered mortgages on the title.
Remote purchase with a power of attorney
If you cannot travel to Thailand, you can grant a power of attorney (POA) to a local representative - a lawyer, for example - to sign documents at the Land Office on your behalf. The POA must be notarized in your home country and authenticated by the Thai embassy or consulate there (or apostilled if your country is a Hague Convention member). Allow 2-4 weeks for this process. The actual Land Office transfer can then proceed without your physical presence.

Step-by-step walkthrough
Step 1: Reservation - what do you sign and what does it cost?
The reservation agreement is a short document (2-4 pages) that records the unit, agreed price, and booking fee. The fee is typically THB 50,000-200,000 for off-plan and 1-3% of price for resale (indicative). It is deducted from the final price at transfer.
Before signing, confirm: the unit number, floor, area in square meters, parking allocation, and the refund conditions if the SPA is not issued in time. Some reservations are non-refundable. Read this clause carefully.
Step 2: Due diligence - what documents must you demand?
Due diligence for a condo purchase covers four areas:
Title: Demand the original chanote (Nor Sor 4 Jor - the highest-grade Thai title deed, confirming precise GPS-surveyed boundaries). Confirm the chanote is in the developer's or seller's name with no encumbrances. Ask the Land Office to issue a title search report (available in person or via a Thai lawyer for a small fee).
Developer or seller integrity: For off-plan, obtain a current company affidavit from the Department of Business Development. Check authorized signatories, registered capital, and that there are no dissolution proceedings. For resale, confirm the seller's ID matches the name on the chanote.
Regulatory approvals: For off-plan, verify the EIA approval (projects above a defined size threshold require it) and the building permit. A project that started construction without these approvals carries legal risk for all buyers.
Condo-specific checks: Confirm the unit is within the 49% foreign freehold quota. Get a debt clearance letter from the juristic person confirming no outstanding common area fees or sinking fund arrears against the unit. Check the building's maintenance fund balance if records are available.
Budget THB 15,000-40,000 for a Thai property lawyer to conduct and document this review (indicative).
Step 3: Sale and purchase agreement - what must the SPA contain?
The SPA (also called the purchase agreement or transfer agreement) is the binding contract. It must specify:
- Full legal description of the unit and its area
- Total price and payment schedule with milestone definitions (for off-plan)
- Transfer date
- Penalties for late completion by the developer (typically 0.01-0.1% of price per day, indicative)
- Warranties on construction quality and the defect liability period (typically 1-2 years)
- Conditions for cancellation and refund
Have a Thai lawyer review the SPA before signing. Standard developer contracts favor the developer. Key points to negotiate: the penalty rate for delays, the conditions defining 'force majeure' (which developers sometimes use to avoid penalties), and the defect warranty scope.
Step 4: International money transfer and the FET form - how do you get this right?
This step is where many foreign buyers make a costly error.
To register foreign freehold condo ownership at the Land Office, Thai law requires proof that the purchase funds came from abroad in foreign currency. This proof is the FET form (Foreign Exchange Transaction form), issued by the receiving Thai bank after each qualifying inward transfer.
How the FET form works:
- You transfer funds from your overseas bank account in a foreign currency (USD, EUR, GBP, SGD, etc.) to the developer's or seller's Thai bank account, or to your own Thai bank account
- When the funds arrive in Thailand, the receiving Thai bank converts them to Thai baht and issues an FET form for each transaction above USD 50,000 equivalent (for smaller amounts, a credit advice letter from the bank serves the same purpose)
- The FET form records: your name, the amount in foreign currency, the amount in baht, and critically, the purpose of the transfer
The purpose code is critical. The transfer purpose must clearly reference the property purchase - for example, 'purchase of condominium unit at'. If the purpose is left blank, coded as a personal transfer, or misworded, the FET form may not be accepted at the Land Office. Correcting a wrong FET form after the fact is difficult and sometimes impossible without re-routing the funds.
Practical instructions:
- Before transferring, call or email the receiving Thai bank and confirm the correct purpose wording they will record
- Transfer the exact amount shown on your payment schedule, not a round number that differs
- Keep every FET form. You will need them at transfer and again when you eventually sell the unit and want to repatriate proceeds
- For off-plan projects with multiple payment tranches, you need a separate FET form (or credit advice letter) for each inward transfer
Step 5: Land Office registration - what happens on transfer day?
The Land Office (Samnak Ngan Thi Din) is the government authority that registers property ownership in Thailand. Transfer of a condo unit requires a physical visit to the Land Office in the district where the project is located.
Documents you bring:
- Original passport (and copies)
- All original FET forms and credit advice letters covering the full purchase price
- Original SPA
- Reservation agreement
- If using a POA: the authenticated original POA and the attorney's ID
Documents the seller or developer brings:
- Original chanote title deed
- Tax clearance documents
- Company documents (for developer sellers)
Costs at transfer (indicative, as of 2026):
- Transfer fee: 2% of the registered value, split by negotiation (often 50/50 or 100% buyer or seller)
- Specific Business Tax (SBT): 3.3% of the registered value or appraised value, whichever is higher, paid by the seller if they have held the unit for fewer than 5 years
- Stamp duty: 0.5%, only applies if SBT does not apply
- Withholding tax: paid by the seller, calculated on a sliding scale based on the seller's ownership period and the appraised value
- Sinking fund: one-time payment, typically THB 400-700 per sqm (indicative, set by the juristic person)
- Common area fee: often 1-3 months pre-paid at transfer
The Land Office officer will review all documents, verify the foreign quota availability in the building's official records, and register the transfer in the land registry system. You leave with a new chanote issued in your name. The process takes 2-4 hours on transfer day.
Step 6: Handover - what do you inspect before accepting the keys?
For off-plan units, handover follows construction completion and usually precedes or coincides with the Land Office transfer. Before accepting the keys:
- Conduct a snagging inspection: check all finishes, fittings, electrical sockets, water pressure, air conditioning units, and windows. Bring a snagging checklist or hire a professional inspector (fees: THB 3,000-8,000, indicative)
- Confirm that the unit's actual area matches the SPA. Minor variances are common; the SPA should state the adjustment formula
- Confirm that included furniture or fittings specified in the contract are present and functional
- Do not sign the handover acceptance form until all snagging items are listed and the developer has committed to a repair timeline in writing
For resale units, the same inspection logic applies before the Land Office transfer.
Risks and mistakes
Wrong FET form purpose code. As explained above, a misworded transfer reference can block your ownership registration. Verify the exact wording with the receiving Thai bank before you send the funds.
Off-plan without verified permits. Buying into a project that lacks a valid EIA or building permit exposes you to forced demolition risk, permit withdrawal, or inability to register ownership. Verify these documents independently through a lawyer.
Assuming the 49% quota is available. Some popular buildings in Bangkok and Phuket have fully allocated their foreign quota. Confirm availability at the juristic person office before signing anything.
Outstanding fees on a resale unit. Common area fees and sinking fund arrears attach to the unit, not just to the previous owner. A debt clearance letter from the juristic person is essential.
Buying through a Thai company to get around restrictions. Foreign buyers sometimes consider buying land or a villa through a Thai-registered company. This is a separate and much more complex topic. It carries legal risks, ongoing compliance costs, and is the subject of active regulatory scrutiny. It is outside the scope of this condo-specific guide.
Power of attorney errors. A POA that is correctly notarized but not properly authenticated for Thai use will be rejected at the Land Office. Confirm the exact requirements with your Thai lawyer before having the document executed abroad.
Relying on the developer's contract without review. Standard off-plan contracts are written for the developer's benefit. Have a Thai lawyer review and, where possible, amend the contract before signing.
FAQ
Can a foreigner own a condo in Thailand freehold?
Yes. Under the Condominium Act (B.E. 2522, as amended), foreign nationals can own condo units in their personal name in freehold, as long as the building's foreign ownership does not exceed 49% of total unit area.
What is the FET form and why does it matter?
The FET (Foreign Exchange Transaction) form is issued by a Thai bank when foreign currency arrives from abroad and is converted to baht. It proves that purchase funds came from overseas in foreign currency. The Land Office requires it to register foreign condo ownership. You also need it to repatriate sale proceeds when you sell.
How long does it take to buy a resale condo in Thailand?
From accepted offer to Land Office title transfer, a straightforward resale purchase typically takes 30-90 days. The main variables are due diligence duration, mortgage timelines if any, and Land Office appointment availability.
Can I buy a Thai condo without visiting Thailand?
Yes. You can grant a notarized and authenticated power of attorney to a Thai representative - typically a lawyer - who attends the Land Office on your behalf. Allow 2-4 additional weeks for POA preparation and authentication in your home country.
What documents must I demand for an off-plan condo purchase?
You must demand: the chanote (title deed) for the project land, the EIA approval letter, the building permit, and a current company affidavit of the developer (not older than 3 months). Do not sign the SPA without all four.
What are the total buying costs at the Land Office in 2026?
The main fees are: a 2% transfer fee, 3.3% Specific Business Tax paid by the seller if they have owned for under 5 years, and 0.5% stamp duty when SBT does not apply. As a buyer, your direct Land Office cost is typically 1% (half of the 2% transfer fee, by common negotiation). Add the sinking fund (indicative: THB 400-700 per sqm) and prepaid common area fees.
What is a chanote title deed?
A chanote (Nor Sor 4 Jor) is the highest-grade Thai property title deed. It confirms GPS-surveyed boundaries and is the required title type for freehold condo ownership registration. Insist on a chanote. Lower-grade documents do not offer the same legal certainty.
Is there any buyer protection if an off-plan developer defaults?
There is no government-backed guarantee scheme for off-plan buyers in Thailand. Protection comes from three sources: construction-linked payment schedules (you do not pay the next tranche until the milestone is reached), contractual penalties in the SPA for developer default, and thorough pre-purchase developer verification. Conducting company affidavit checks and reviewing the developer's track record before signing is the most important step you can take.
What is the sinking fund?
The sinking fund is a one-time capital reserve payment made at the time of condo unit purchase or transfer. It funds major future building repairs (roof, lifts, facade). The amount is set by the juristic person and is typically THB 400-700 per sqm (indicative). For resale, confirm there are no arrears on the unit before transfer.
Can I repatriate my money when I sell the condo?
Yes, provided you have the original FET forms for your inward transfers. The Thai bank will allow you to remit the lower of the registered transfer price and the original foreign currency amount documented in your FET forms. Keeping all FET forms is essential from day one.
