Buying an Apartment in Bangkok as a Foreigner: 2026 Guide

Foreigners can legally buy an apartment (condominium unit) in Bangkok under the Condominium Act B.E. 2522 (1979, as amended). You take direct freehold ownership - your name goes on the title deed. The process has six main stages: reservation, due diligence, sale and purchase agreement, international money transfer with an FET form, Land Office registration, and handover. Each stage has a defined cost, a defined timeline, and specific documents you must either sign or demand.

The single most important rule: funds must arrive in Thailand from abroad, in foreign currency, with a clear transfer purpose. That triggers the Foreign Exchange Transaction form (FET form) - a bank-issued record that proves the money came from outside Thailand. Without a valid FET form for each payment, you cannot register condo ownership as a foreigner at the Land Office, and you cannot legally repatriate the money when you sell.

Quick answer

  • Foreigners can own up to 49% of the total floor area of any condominium building as foreign quota units
  • The full buying process takes 4 to 12 weeks for ready units; off-plan purchases add the construction period (typically 2 to 4 years)
  • Buyer-side costs at registration: transfer fee 2% of appraised value, withholding tax paid by seller (often negotiated), stamp duty 0.5% or specific business tax 3.3% (not both), plus your own legal fees
  • The FET form (Foreign Exchange Transaction form) is issued by a Thai bank when you receive an international wire in foreign currency; it is mandatory for foreign-quota condo registration
  • A wrong bank transfer reference is one of the most common and costly errors - the FET form records the stated purpose; if the bank codes it incorrectly, registration can be refused
  • You can complete most steps remotely using a Thai-law power of attorney (POA), but you or your representative must appear at the Land Office on registration day

Options and scenarios

Scenario 1: Ready-to-transfer condominium unit in Bangkok

This is the most straightforward path for a foreign buyer. The unit exists, you can inspect it, and title transfer can happen within weeks of signing the sale and purchase agreement (SPA).

Typical timeline: 4 to 8 weeks from reservation to key handover.

Payment flow:

  • Reservation deposit (indicative: THB 50,000 to THB 200,000) - paid on-site or by wire
  • Down payment (typically 20% to 30% of price) - must arrive from abroad in foreign currency to generate an FET form
  • Final balance at Land Office registration

Every wire you send from abroad should reference 'purchase of condominium unit'. Ask your Thai bank to issue an FET form (also called a Thor Tor 3 form at some banks) for each inbound transfer. Keep originals - you will need them at the Land Office and again when you sell.

Scenario 2: Off-plan purchase from a developer

You buy before construction completes. You make staged payments tied to construction milestones: for example, 10% on reservation, 10% on foundation completion, 10% on structure completion, and the remaining 70% on transfer.

Timeline: Reservation to handover typically 2 to 4 years for Bangkok projects as of 2026.

Key risk: The developer may delay or, in rare cases, fail to complete. Thailand has no mandatory government-backed escrow for real estate buyers. Your protection comes from:

  • Construction-linked payment schedules written into the SPA - you pay only when a defined milestone is reached and verified
  • Contractual penalty clauses - the SPA should specify a daily penalty (commonly 0.01% of the purchase price per day) if the developer misses the handover date
  • Developer verification before you sign - see the due diligence checklist below

Documents to demand from the developer before signing anything:

  1. Chanote title deed (Nor Sor 4 Jor) - the highest-grade Thai land title; confirms the land is properly registered. A chanote has a unique plot number cross-referenced with the Land Department database
  2. Company affidavit of the developer (issued by the Department of Business Development, dated within 3 months) - confirms the developer company is registered, active, and its directors are authorized to sell
  3. Environmental Impact Assessment (EIA) approval - required for Bangkok condominiums above certain height or unit thresholds; without it, construction can be halted
  4. Construction permit (building permit) - confirms the project is legally authorized to build
  5. Condominium registration certificate - for ready units, confirms the building is legally registered as a condominium under the Condominium Act
  6. Foreign quota availability confirmation - the developer should confirm in writing that sufficient foreign-quota units remain (the 49% ceiling)

Scenario 3: Resale unit from a private seller

You buy from an individual, not a developer. Due diligence is more complex because you deal directly with a private party.

Additional checks for resale:

  • Obtain the title deed (chanote) number and verify it at the Land Office or via a lawyer - confirm no mortgages, liens, or disputes are registered
  • Demand the seller's juristic person (the building's management company) clearance letter confirming no outstanding common area fees or sinking fund arrears. A sinking fund is a one-time upfront contribution to the building's reserve for major repairs, typically THB 400 to THB 700 per square meter
  • Confirm the unit is in the foreign quota, not the Thai quota

The FET form: exact mechanics

The FET form (Foreign Exchange Transaction form, sometimes called Thor Tor 3) is issued by a Thai commercial bank when it receives an inbound international wire in foreign currency (USD, EUR, GBP, AUD, and others). The bank converts the foreign currency to Thai baht and records the transaction purpose.

Four rules you must follow:

  1. Send from your own account abroad. The name on the sending account must match the buyer's name on the SPA and on the title deed application.
  2. Send in foreign currency, not Thai baht. If you wire THB from an offshore THB account, some banks will not issue a qualifying FET form. Confirm with your receiving Thai bank before the transfer.
  3. State the purpose clearly in the transfer reference field. Use wording such as: 'Purchase of condominium unit, Bangkok, Thailand.' The bank codes the purpose on the FET form based on what you write.
  4. Request the FET form immediately after each transfer. Do not wait. Ask the receiving bank for the original document. Store physical and digital copies.

Amount threshold: As of 2026, each FET form covers one transfer. If your total purchase price requires multiple transfers (for example, staged payments on an off-plan unit), you need a separate FET form for each wire. The total amount shown across all your FET forms must equal or exceed the total registered purchase price to support full ownership registration.

At exit (when you sell): The Land Office and your bank will require you to present the original FET forms to authorize repatriation of sale proceeds abroad. Missing FET forms can delay or prevent you from sending your money home after a future sale.

Step-by-step buying process in Bangkok

Step 1: Reservation (Week 1)

You pay a reservation deposit to hold the unit. For developer sales, this is typically THB 50,000 to THB 200,000. For resales, it varies.

What you sign: A reservation agreement. Read it carefully - some agreements are non-refundable if you withdraw after signing.

What to demand at this stage:

  • Written confirmation that the unit is in the foreign quota
  • Draft SPA for your lawyer to review before you commit

Step 2: Due diligence (Weeks 1 to 3)

This runs in parallel with reservation and SPA negotiation. Engage a Thai property lawyer. Legal fees for due diligence and SPA review: indicatively THB 20,000 to THB 80,000 depending on complexity.

Checklist:

  • [ ] Chanote title deed - verified at Land Office or by lawyer
  • [ ] Company affidavit of developer or seller's ID and title confirmation
  • [ ] EIA approval (off-plan and new buildings)
  • [ ] Construction/building permit
  • [ ] Condominium registration certificate
  • [ ] Foreign quota availability in writing
  • [ ] Outstanding common fee and sinking fund clearance (resale)
  • [ ] No encumbrances on the title (mortgages, liens, court orders)

Step 3: Sale and purchase agreement (Weeks 2 to 4)

The SPA is the binding contract. For off-plan purchases, this is the most important document you will sign.

Key clauses to negotiate and confirm:

  • Exact unit specification (floor plan, finishes, furniture if included)
  • Payment schedule tied to specific, verifiable construction milestones
  • Penalty clause for developer delay (daily rate, minimum 0.01% per day is standard market practice)
  • Your right to cancel and receive a full refund if EIA, building permit, or condominium registration is not obtained
  • Force majeure definition (should be narrow)
  • Defect liability period (minimum 1 to 2 years post-handover)
  • Governing law: Thai law

Remote signing: You can sign the SPA abroad using a Thai-law power of attorney. The POA must be notarized and, if signed outside Thailand, authenticated by the Thai embassy or consulate in your country (or apostilled if your country is an Apostille Convention member). Allow 2 to 4 weeks for this process.

Step 4: International money transfer and FET forms (Ongoing)

Follow the four FET rules stated above for every payment. Keep a payment record that maps each wire to its FET form and to the payment milestone in the SPA.

For a ready unit, you typically send one or two wires. For an off-plan unit, you may send four to six over the construction period.

Step 5: Land Office registration (Transfer day)

This is the day ownership legally transfers. It happens at the Bangkok Land Office district where the building is located. You or your authorized representative (via POA) must appear in person.

Documents you bring:

  • Passport (original)
  • All original FET forms totaling the purchase price
  • SPA
  • POA (if applicable, with authentication)

Documents the seller/developer brings:

  • Original chanote title deed
  • Condominium unit title (Nor Sor 5, the unit-specific deed)
  • Juristic person (building management company) clearance letter
  • Tax clearance documents

Costs paid at the Land Office (indicative, as of 2026):

  • Transfer fee: 2% of the Land Department's appraised value (often split equally between buyer and seller, but this is negotiable)
  • Specific Business Tax (SBT): 3.3% of the higher of appraised or sale price, paid by the seller if the unit has been held for less than 5 years
  • Stamp duty: 0.5% of the higher of appraised or sale price, applies instead of SBT if the seller has held the unit for 5 or more years
  • Withholding tax: paid by the seller, amount depends on seller type and holding period

Budget for your share of transfer costs: approximately 1% to 2% of the purchase price, depending on negotiations.

Step 6: Handover and post-transfer checklist

After registration, you receive the keys and the original unit title deed (chanote or unit-specific deed) in your name.

Handover checklist:

  • [ ] Confirm the title deed shows your full legal name exactly as in your passport
  • [ ] Inspect the unit against the SPA specification - note defects in writing on the handover form before signing
  • [ ] Obtain meter numbers for electricity and water
  • [ ] Register with the juristic person (building management) as the new owner
  • [ ] Pay the sinking fund (if not already paid) and first common area fee installment
  • [ ] Store your title deed, FET forms, and SPA in a secure location

Risks and mistakes

1. Wrong FET form reference If you wire money without stating 'purchase of condominium unit' in the reference, the bank may code the purpose as a general transfer or a loan. The Land Office can reject FET forms coded incorrectly. Correcting this after the fact is possible but time-consuming and not guaranteed. Always state the exact purpose before you send.

2. Buying in the Thai quota by mistake Some developers sell units to foreigners in the Thai quota, typically through a Thai company structure. This is a different ownership model with separate legal requirements and risks. Confirm in writing before reservation that your unit is in the foreign freehold quota.

3. Skipping the title deed verification A small number of Bangkok projects have been sold on land with unresolved title issues. Always verify the chanote at the Land Office, not just from a developer brochure. Your lawyer can do this for you.

4. Paying a large deposit before reviewing the SPA Some developers collect significant deposits before providing the full SPA. Resist this. Pay only a small reservation fee until your lawyer has reviewed the draft SPA and confirmed the key protections are in place.

5. Assuming developer verbal promises are binding If a view, a finish standard, a completion date, or a rental guarantee is not in the signed SPA, it does not exist legally. Write every commitment into the contract.

6. Ignoring common fee arrears on resale units If the previous owner owes unpaid common area fees, the juristic person (building management) can pursue the debt from the new owner in some circumstances. Get a clearance letter before transfer.

7. Not accounting for currency risk on off-plan staged payments If you are paying in THB but earning in another currency, exchange rate movements over a 2 to 4 year construction period can materially change your effective purchase price. Factor this into your budget.

8. Using a POA that has not been properly authenticated An unauthenticated or incorrectly formatted POA will be rejected at the Land Office. Your lawyer should prepare the POA and confirm the authentication requirements for your country of residence.

FAQ

Can a foreigner own an apartment in Bangkok outright?

Yes. Under the Condominium Act, a foreign national can hold direct freehold title to a condominium unit in Thailand. Your name appears on the title deed. The building's foreign ownership quota must not exceed 49% of total floor area.

What is the FET form and why does it matter?

The FET form (Foreign Exchange Transaction form) is a document issued by a Thai bank confirming that funds arrived from abroad in foreign currency. The Land Office requires it to register condo ownership in a foreign name. You also need it when repatriating proceeds after a future sale. One form per inbound wire transfer.

How much money do I need beyond the purchase price?

Budget an additional 2% to 4% of the purchase price for transfer and registration costs. Add THB 20,000 to THB 80,000 for legal fees. Sinking fund (indicatively THB 400 to THB 700 per sqm) and the first quarter of common area fees are also due at or before handover.

Can I buy a Bangkok apartment without visiting Thailand?

Yes, for most steps. You can review and sign documents remotely, and you can transfer funds from abroad. You need a Thai-law power of attorney, properly notarized and authenticated, to authorize a representative to sign at the Land Office. Allow 2 to 4 extra weeks to prepare the POA.

What is a chanote title deed?

A chanote (Nor Sor 4 Jor) is Thailand's highest-grade land title. It is precisely surveyed, registered in the Land Department's database, and fully transferable. When buying a Bangkok condominium, confirm the underlying land has a chanote and that your unit's title is the condominium-unit version of this document.

What is a juristic person in Thai property?

The 'juristic person' is the legal management entity of a condominium building - similar to a homeowners association or building management company. It collects common area fees, manages the building, and issues clearance letters confirming whether an owner's fees are paid. You register with it as the new owner at handover.

Is there any protection if an off-plan developer stops construction?

There is no government-backed fund or mandatory escrow for buyers in Thailand. Your protection comes from: a construction-linked payment schedule in the SPA (you pay only when milestones are met and verified), penalty clauses for delay, your right to cancel for defined breaches, and thorough developer due diligence before you sign. Verify the developer's financial standing and track record before paying any deposit.

How long does the Bangkok apartment buying process take?

For a ready unit: 4 to 8 weeks from reservation to title transfer. For an off-plan unit: add the construction period, typically 2 to 4 years for Bangkok projects currently under development as of 2026.

What if I send money in Thai baht instead of foreign currency?

Sending THB from an offshore account may not generate a qualifying FET form. Always confirm with your receiving Thai bank before transferring. The standard, safest approach is to wire USD, EUR, GBP, AUD, or another major foreign currency from your overseas bank account to your Bangkok bank, which then converts it to THB.

Can I rent out my Bangkok apartment after buying?

Yes. There are no restrictions on leasing a foreign-owned condominium. Short-term rental (fewer than 30 days) may require a hotel license for the building under Thai law, so check the building's operational rules. Long-term rental (30 days or more) is straightforward and does not require a special license for an individual unit owner.
