To buy property in Thailand as a foreigner, you generally send your purchase funds into the country in foreign currency, and the receiving Thai bank issues a Foreign Exchange Transaction (FET) form — sometimes called a credit advice or foreign-currency credit note — confirming that the money arrived from abroad for a property purchase. This single document does two important jobs: it allows a condominium to be registered in your name as foreign freehold, and it is the key that lets you send your capital back home when you eventually sell. Get the transfer right and the rest of the purchase is smooth; get it wrong and you can face avoidable delays at the Land Office. Here is exactly how it works in 2026.
Why the money must arrive in foreign currency
The rule that trips up newcomers is simple but strict: to support a foreign-freehold registration, the funds must be remitted into Thailand from overseas in a foreign currency (for example US dollars, euros, pounds or Singapore dollars) and then converted to Thai baht inside Thailand, by the receiving bank.
The reason is that Thai authorities want clear evidence the purchase money genuinely originated abroad. If you were to change your money to baht overseas and wire baht in — or move money through an account already sitting in Thailand — the bank cannot certify it as an inbound foreign-currency remittance for a property purchase, and the paperwork you need may not be issued. So the currency you send matters just as much as the amount.
This requirement flows directly from Thailand's ownership rules for foreigners. If you are still getting your bearings on those, start with can foreigners own property in Thailand, then come back here for the money side.
What the FET form actually is
The Foreign Exchange Transaction form is the official record, produced by the receiving Thai bank, that confirms a foreign-currency sum entered Thailand and states the purpose of the transfer — in your case, the purchase of a specific property. For larger transfers the bank issues the FET form itself; for smaller amounts the bank provides an equivalent credit advice or certificate that serves the same evidential role.
Two things make the FET form so important:
- It enables foreign-freehold registration. The Land Office needs to see that your purchase funds came from abroad in foreign currency before it will record a condominium in your name within the building's foreign quota.
- It underpins repatriation. When you sell and want to move the proceeds out of Thailand, the FET form from your original purchase is the evidence that the capital came in from overseas in the first place.
The single most valuable habit you can adopt is this: keep the FET form (and every related bank document) safe from day one. You will want it years later, and reconstructing it after the fact is far harder than filing it away now.
Step by step: transferring your funds
The mechanics are straightforward when you plan them in advance:
- Agree the details in the contract. Your Sale and Purchase Agreement will set out the price, the payment schedule and the account to receive funds. Confirm these with your lawyer before sending anything.
- State the purpose clearly. When you instruct your transfer, ensure the payment reference or purpose field records that the funds are for the purchase of property (ideally naming the unit or project). This helps the Thai bank issue the FET form correctly.
- Send in foreign currency. Remit the money in your home currency so it arrives as a foreign-currency credit and is converted to baht by the receiving bank in Thailand.
- Ask the bank for the FET form or credit advice. Do not assume it will be produced automatically — request it explicitly and confirm it names the correct purpose and amount.
- Pass the document to your lawyer. Your legal team uses it, alongside the other completion documents, to register your ownership at the Land Office.

What about mortgages and financing?
Many buyers ask whether they can borrow locally rather than transfer the full amount. In general, Thai banks do not lend to foreign buyers, so the market is largely cash-based. There are limited exceptions — for instance a foreigner with a Thai spouse who has taxable income, and some offshore lenders or developer-financing arrangements — but these are the exception rather than the rule.
In practice, the most common form of "financing" for foreigners is the payment structure on off-plan projects, where developers typically offer interest-free stage payments spread across the roughly two-to-three-year construction period. Each of those instalments should still be remitted in foreign currency so that the FET documentation builds up correctly as you go. Budgeting on a cash basis, with the FET paperwork captured at every stage, keeps you on the safe side.
Repatriating your money when you sell
The FET form is not just a purchase formality — it is your exit ticket. When you sell your Thai property and want to move the proceeds abroad, you will generally need to show that the money originally came into Thailand from overseas. The FET form from your purchase is the primary evidence for this, which is why keeping it matters so much.
Repatriation sits alongside the taxes due on a sale, so plan the two together. Our guide to property taxes in Thailand for foreign buyers covers the selling-side costs, and combining clean FET records with good tax records makes the whole exit far simpler.
Treat the FET form as a permanent asset, not a one-time receipt. It lets you register ownership on the way in and take your capital home on the way out.
Common mistakes to avoid
A short list of the errors we most often help clients avoid:
- Sending baht instead of foreign currency, or converting to baht before the money reaches Thailand — this can break the foreign-freehold paperwork.
- Leaving the purpose field blank on the transfer, so the bank cannot tie the funds to a property purchase.
- Not requesting the FET form and only realising at the Land Office that it is missing.
- Losing the documents after completion, then struggling to repatriate funds years later.
- Moving money through a Thai-based account rather than remitting fresh from abroad.
- Cutting the amount too fine — remember to budget for the roughly 5% to 7% of purchase-side fees on top of the price, and transfer enough to cover them.
Conclusion
Transferring money to Thailand to buy property is not complicated, but it is precise: send your funds from abroad in foreign currency, make the purpose clear, obtain the FET form or credit advice from the receiving bank, and keep every document safe. Done properly, it lets you register a condominium in your own name and repatriate your capital cleanly when you sell.
