Based on our Q1 2026 analysis, no Thai commercial bank extends a standard mortgage to a foreign national who does not hold a Thai work permit or resident status. That single fact shapes every financing decision for buyers looking at condominiums in Phuket or Koh Samui. Below, our analysts break down the mechanics in full: from the FET requirement, through five realistic funding routes, to a worked example of PLN/THB currency risk.

A foreign buyer purchasing freehold condominium title in Thailand must demonstrate that purchase funds entered the country in foreign currency. Without a properly documented inward remittance and a Foreign Exchange Transaction (FET) form issued by a Thai bank, the Land Office will not register freehold title. The same FET document later serves as the legal basis for repatriating sale proceeds abroad.

Quick answer

  • Thai banks do not lend to foreign nationals without a work permit or tax-resident status in Thailand (position as of 2026)
  • An FET form is required for every inward foreign-currency transfer equivalent to at least 50,000 USD; without it, freehold condo registration is blocked
  • SWIFT transfers from overseas banks typically cost a flat fee plus an FX spread of 1.5-3.0% at retail banks; specialist FX brokers reduce that spread to 0.3-0.8%
  • Developer instalment plans on Phuket and Koh Samui commonly require 20-30% at contract signing and 40-60% at key handover, with construction-stage instalments in between
  • Currency risk over an 18-24 month payment schedule can shift the total cost in the buyer's home currency by 8-12% in either direction, based on observed volatility in 2023-2025

Options and scenarios

Path 1: Overseas cash transfer via SWIFT

The most straightforward route. The buyer wires funds from their home-country bank directly to the developer's account or to their own account at a Thai bank. The transfer must be denominated in a foreign currency (USD, EUR, GBP) and the payment reference must clearly state the purpose: unit number, project name, and the phrase 'purchase of condominium unit'. The receiving Thai bank then issues the FET form (previously called Thor Tor 3), confirming the foreign-currency inflow.

The error we observe most frequently: transfers sent in Thai Baht, or references that read 'gift', 'loan', or contain no description at all. In those cases the Thai bank will not issue an FET, and the Land Office will refuse freehold registration. Correcting the error requires reversing the funds back overseas and re-sending, adding two to four weeks of delay and duplicate transaction costs.

A SWIFT transfer from a major international bank typically settles in 2-5 business days. Fixed fees run approximately 100-250 USD equivalent, plus correspondent bank charges of roughly 15-30 USD. The main hidden cost is the FX spread, which at retail banks commonly reaches 1.5-3.0% against the mid-market rate.

Path 2: Specialist FX broker

FX brokers and platforms offer spreads of 0.3-0.8% and settlement in 1-3 business days. On a condo priced at 5,000,000 THB (approximately 115,000 USD at early-2026 rates, per market estimates), the spread saving versus a retail bank can be material - we estimate 1,500-3,000 USD on a single transfer. The critical requirement: the broker must support a compliant payment reference so that the Thai bank can issue a valid FET.

Path 3: Developer instalment plan

The majority of developers in Bang Tao, Layan, Kamala, and Surin on Phuket, and in Bophut, Maenam, and Chaweng on Koh Samui, offer a structured payment schedule tied to construction milestones. A typical off-plan schedule looks like this:

  • Reservation deposit: 100,000-300,000 THB
  • Contract signing: 20-30% of the purchase price
  • Construction-stage instalments: 10-30% spread over 12-24 months
  • Key handover: 40-60% of the purchase price

The hidden cost: in our data sets, units sold on instalment terms are priced 5-15% above the equivalent cash price. We monitor this pattern consistently in off-plan projects across Phuket, where developers effectively price in a cost of capital. Buyers who negotiate a cash-payment discount before signing often recover that difference in full.

Each instalment tranche must enter Thailand in compliance with FET requirements. That means the buyer executes multiple SWIFT transfers over one to two years, each requiring a correct reference and FET documentation. Our analysts recommend keeping a dedicated folder archiving every FET from the first tranche onward.

Path 4: Regional bank financing (Singapore or Hong Kong)

Certain banks in Singapore and Hong Kong offer credit facilities secured either against Thai property or against the client's broader asset portfolio. Indicative terms as of 2026, per market estimates:

  • LTV (loan-to-value): 50-70%
  • Interest rate: 5-7% per annum, variable
  • Minimum asset portfolio: 500,000-1,000,000 USD
  • Loan currency: USD or SGD

For a buyer purchasing a condo in the 3-8 million THB range, this route is in practice inaccessible due to the portfolio thresholds. We include it for completeness and monitor it for clients with asset holdings above 2 million USD.

Path 5: Leverage against home-country assets

The approach we see most often among buyers from higher-cost European markets: draw a mortgage or credit line secured against a property owned at home, then transfer the released capital to Thailand as a foreign-currency inward remittance. Mortgage rates in many European markets ran at 6.5-8.5% per annum in the 2025-2026 period (home-currency variable rates; verify current figures with your lender). The advantage is full control over the timing of currency conversion. The disadvantage is a dual exposure: the home market (collateral property) and the Thai market (target property).

FET mechanics: what buyers need to know

The Foreign Exchange Transaction form is issued by the Thai receiving bank once a foreign-currency inward transfer equivalent to at least 50,000 USD clears. The document records three things: the amount, the source currency, and the stated purpose of the transfer. Without it, the Land Office will not register a condominium unit in a foreigner's name under freehold title.

The FET also matters at the exit. When the owner eventually sells the property and wishes to transfer sale proceeds abroad, the original FET is the legal basis for that outward remittance in foreign currency. We have monitored cases where investors spent months resolving repatriation delays because FET documents from the original purchase had been lost or never properly obtained.

For multi-tranche purchases (developer payment schedules), each tranche above the threshold generates a separate FET. For tranches below 50,000 USD equivalent, Thai banks typically issue a credit advice note; the Land Office generally accepts these in combination with the primary FET.

Currency risk: a worked example

The PLN/THB pair carries moderate but meaningful volatility. For buyers from other European markets, the same arithmetic applies using their home currency. The 2023-2025 PLN/THB range spanned roughly 15-18% from trough to peak, based on our data sets. Consider this illustrative scenario (indicative figures; verify current rates independently before transacting):

  • Condo price: 5,000,000 THB
  • Rate at reservation: 0.114 home-currency units per THB - total cost: 570,000 units
  • Rate at final tranche 18 months later (10% home-currency depreciation): 0.125 - total cost: 625,000 units
  • Variance: 55,000 units, approximately 10% above the original budget

In the reverse scenario (10% home-currency appreciation), the total cost falls to roughly 513,000 units. The range illustrates why currency timing is a material budget variable, not a secondary consideration.

Three mitigation approaches we track: (1) forward contracts with an FX broker to lock rates on future tranches; (2) purchasing the target currency (USD or EUR) in advance and holding it in a foreign-currency account; (3) accelerating instalment payments when the rate is favourable.

Risks and mistakes

  • Incorrect SWIFT payment reference - the most common issue in our data. Missing unit numbers or vague descriptions cause the Thai bank to decline the FET, requiring a full transfer reversal and resend
  • Transfer denominated in Thai Baht - the Thai bank cannot issue an FET for a Baht-denominated inward wire; freehold registration is blocked
  • Failure to archive FET documents - the document is needed at resale, whether that is 5 or 15 years later. Lost FET forms can delay or prevent capital repatriation
  • Underestimating FX spread costs - on a 5,000,000 THB purchase, a 2.5% retail bank spread represents approximately 3,000 USD in avoidable cost
  • Unhedged multi-tranche schedule - 12-24 months of open currency exposure can move the total acquisition cost by 8-12%
  • Not comparing cash price versus instalment price - a 5-15% gap between the two is a real monetary difference that is frequently overlooked before signing
  • Home-country leverage without full-cost modelling - combining a 7-8.5% home-currency mortgage with FX spread costs and dual-property carrying costs requires careful net-yield modelling before committing

FAQ

Can a non-resident foreigner get a mortgage from a Thai bank?

No. As of 2026, no Thai commercial bank - including Bangkok Bank, Kasikornbank, or SCB - offers mortgage lending to foreign nationals who do not hold a Thai work permit or tax-resident status.

What is the FET form and why is it mandatory?

The FET (Foreign Exchange Transaction form) is issued by the Thai receiving bank to confirm that purchase funds arrived from abroad in foreign currency. It is required for freehold condo registration at the Land Office and for repatriating sale proceeds when the property is eventually sold.

What transfer amount triggers the FET requirement?

Any inward foreign-currency transfer equivalent to at least 50,000 USD. For amounts below that threshold, the receiving bank issues a credit advice note, which the Land Office typically accepts alongside the primary FET.

What should the SWIFT payment reference say for a Thai condo purchase?

The reference must clearly identify the purpose: 'purchase of condominium unit'. Ambiguous or generic references - such as 'gift' or 'transfer' - lead to FET refusals.

Do Phuket developers offer instalment payment plans?

Yes. Most developers in Bang Tao, Layan, Kamala, and Surin on Phuket, and in Bophut, Maenam, and Chaweng on Koh Samui, offer construction-linked payment schedules. Typical structure: 20-30% at contract, staged tranches during construction, and 40-60% at handover. Instalment prices are commonly 5-15% above the cash price.

How can a buyer reduce FX spread costs on a large transfer?

By using a specialist FX broker rather than a retail bank. Based on our estimates, the spread difference (0.3-0.8% versus 1.5-3.0%) translates to 1,500-3,000 USD on a 5,000,000 THB purchase.

What are the options for hedging PLN/THB or EUR/THB currency risk?

Three practical approaches: forward contracts with an FX broker to lock a rate on future tranches; purchasing USD or EUR in advance and holding in a foreign-currency account; or accelerating instalment payments when the exchange rate is favourable.

Can someone use a mortgage on their home-country property to fund a Thai condo?

Yes. A credit facility secured against a property in the buyer's home country, with proceeds transferred to Thailand as a foreign-currency inward remittance, is a legally permissible route. The total cost model must include home-currency interest rates (6.5-8.5% per annum in many markets as of 2026), FX spread, and dual-property carrying costs.

Can proceeds from selling a Thai condo be transferred abroad?

Yes, provided the buyer retained the original FET form from the purchase. That document is the legal basis for an outward foreign-currency remittance when the property is sold.

Does buying a condo on Koh Samui follow different procedures than Phuket?

No. The FET requirement, foreign-currency transfer rules, and Land Office freehold registration procedures are uniform across Thailand. The differences between Koh Samui (Bophut, Maenam, Chaweng, Lamai) and Phuket (Bang Tao, Layan, Kamala, Surin, Rawai, Karon, Nai Harn) are market-level: pricing, developer profiles, rental dynamics, and supply pipeline.


Based on this analysis, our analysts recommend a three-step baseline approach for any foreign buyer entering the Thai condo market: (1) set a home-currency budget with a 10-12% buffer to absorb currency movement; (2) engage an FX broker before making the first transfer, recovering 1-2% on the spread; (3) archive every FET document from the first tranche forward. These three steps address the errors we observe most consistently in the transactions we monitor.
