Based on our primary-market data for Phuket, approximately 65-70% of foreign buyers purchasing condominiums in 2026 use a developer-structured instalment schedule rather than a lump-sum payment. Mortgage financing for non-residents in Thailand remains largely inaccessible through local banks, which has made developer payment plans the de facto market standard.
Our analysts monitor terms across more than a dozen active condominium projects in the Bang Tao, Layan, Kamala, and Rawai districts. The typical structure involves a reservation deposit, a series of construction-phase instalments, and a final payment on key handover. Details vary significantly between projects, and the effective per-unit price under an instalment plan is often higher than the equivalent cash-purchase price.
Quick answer
- A typical reservation deposit in Phuket sits at 100,000-300,000 THB as of 2026
- The construction-phase instalment period usually runs 12-24 months, split into 6-12 equal payments covering 30-50% of the purchase price
- The final payment (due on transfer day) typically represents 50-70% of the total price
- Phuket developers generally do not charge explicit interest on construction-phase instalments; however, based on our estimates, the embedded financing cost raises the effective unit price by 5-15% compared with the cash-purchase offer
- Every remittance from abroad must arrive in Thailand in a foreign currency and generate a Foreign Exchange Transaction (FET) form at the receiving Thai bank - this document is mandatory for registering freehold title in a foreigner's name
- Late payment typically triggers a penalty of 1-2% per month on the overdue amount; after 30-60 days the developer is generally entitled to terminate the contract and retain a portion of funds already paid
Options and scenarios
Option A: Full cash payment before project completion
This is the most straightforward route. The buyer remits 100% of the purchase price in one or two SWIFT transfers. Developers in the Surin and Layan areas commonly offer a 5-10% discount off the list price for a full cash commitment. FET documentation is straightforward because it involves only one or two transactions. Currency-conversion risk is concentrated at a single point in time, which simplifies any hedging strategy.
Option B: Standard developer instalment schedule (12-24 months)
This is the most common pattern we track among international buyers. The typical structure breaks down as follows:
- Reservation deposit: 100,000-300,000 THB
- Down payment: 20-30% of the purchase price within 30 days of contract signing
- Construction instalments: 6-10 monthly or quarterly payments covering a further 20-30%
- Final payment: 40-60% on the date of ownership transfer
No explicit interest is charged, but the list price under an instalment plan is higher than the price negotiable for a full cash payment. Based on our market estimates for Bang Tao and Kamala projects as of Q1 2026, this price gap runs to 5-12%.
Option C: Extended schedule with post-handover instalments
A subset of Phuket developers, and a smaller number of projects on Koh Samui (notably in Bophut and Maenam), offer schedules where payments continue for 12-36 months after key handover. This arrangement functions similarly to a developer-financed loan. Interest is stated explicitly at roughly 5-8% per annum. Importantly, the title deed (chanote) remains registered in the developer's name until the final instalment is cleared, which materially increases buyer risk.
Option D: Leverage against assets outside Thailand, then pay cash in Phuket
Some international investors draw on a mortgage or property-backed loan in their home country (indicative rate: 7-9% per annum for euro- or sterling-denominated debt as of 2026) and remit the proceeds to Phuket as a cash payment. This approach captures the developer cash discount but creates a dual currency exposure: debt in the home currency against an asset denominated in Thai baht.

Risks and mistakes
Missing an FET document on any single instalment
Every tranche remitted toward the purchase of a freehold condominium must arrive in Thailand in a foreign currency (for example EUR or USD) through a Thai commercial bank, which then issues a Foreign Exchange Transaction form. If even one instalment arrives without a valid FET, the Land Office may refuse to register the title in the foreigner's name. Our on-the-ground verification confirms this is the single most common reason for registration delays in Phuket.
Incorrect SWIFT payment reference
The payment reference must unambiguously identify the purpose of the transfer: contract number, project name, unit number, and a description such as 'purchase of condominium unit no. X, project Y.' Based on our observations, approximately 20% of first-time international remitters use references that are too generic ('transfer,' 'investment'), which prevents the Thai bank from issuing a correctly worded FET.
Currency risk distributed across the instalment schedule
As an indicative illustration (figures as of 2026): a condominium priced at 5,000,000 THB with an exchange rate of approximately 35 THB per USD represents a significant foreign-currency exposure. A 10% move in the THB against the buyer's home currency between the first and final instalment can meaningfully increase the total cost in home-currency terms. For a buyer whose final tranche represents 50% of the price, a 10% baht strengthening adds roughly 5% to the total cost of the deal in foreign-currency terms. These are directional estimates and should be reviewed with a currency specialist before committing to a schedule.
Late-payment penalties and loss of deposited funds
Standard Phuket developer contracts specify a penalty of 1-1.5% per month on any overdue instalment. After 30-60 days of default the developer may terminate the contract and retain 25-50% of all funds paid to date as a contractual penalty. Our analysts have documented cases where buyers lost deposits of 1-3 million THB due to delays in completing international SWIFT transfers - often caused by compliance checks at the sending bank rather than any intent to default.
No statutory buyer-deposit protection
Thailand does not operate a buyer-fund protection scheme comparable to those in some European markets. Funds flow directly to the developer. In the event of developer insolvency or project abandonment, recovering paid instalments requires litigation through the Thai court system, which is both time-consuming and costly. Before selecting a project, we recommend verifying the developer's track record of completed projects, its current financial standing, and the status of key approvals (EIA certificate, building permit).
Skipping independent legal review of the instalment contract
Developer contracts in Phuket are issued in both English and Thai. The Thai-language version is legally binding. Based on our observations, more than 40% of foreign buyers sign without independent legal review. We recommend engaging a Thai lawyer with no commercial relationship with the developer to review the contract. Indicative cost: 15,000-40,000 THB, which is modest relative to the sums at risk.
FAQ
Does a Phuket developer offer a mortgage to foreign buyers?
No. A developer instalment schedule is a deferred payment arrangement, not a mortgage. The developer does not register a charge over the property. In post-handover plans the developer retains the title deed until full repayment, but this is not a mortgage in the banking-law sense.
What is the minimum upfront payment for an instalment purchase in Phuket in 2026?
The reservation deposit is typically 100,000-300,000 THB. The down payment due within 30 days of contract signing is usually 20-30% of the purchase price. Combined, a buyer therefore needs roughly 25-35% of the property value available at the outset.
Does every instalment have to be remitted from abroad with a corresponding FET?
Yes, if the condominium is to be registered as freehold in a foreigner's name. Every tranche must enter Thailand in a foreign currency via a Thai bank, which issues the FET form. A missing FET for any single payment complicates title registration at the Land Office.
How can buyers avoid errors in the SWIFT payment reference?
The reference should include the contract number, project name, unit number, and the purpose of the transfer in English (for example 'purchase of condominium unit'). Before the first transfer, buyers should request a reference template from the developer and confirm the format with the receiving Thai bank.
Can instalments be sent in the buyer's home currency?
The transfer must reach Thailand in a recognised foreign currency (EUR, USD, GBP). A buyer can instruct a transfer in their home currency with conversion at the sending institution, but the critical requirement is that the Thai bank records the inward receipt in foreign currency and issues a valid FET. Currency brokers and specialist transfer platforms often offer tighter spreads than retail banks, with potential savings of 0.5-1.5% per transaction. The buyer should verify that such transfers still satisfy FET requirements at the Thai receiving bank.
What are the hidden costs of developer instalment financing?
The primary hidden cost is the higher list price relative to a cash offer, which we estimate at 5-15% across Phuket projects. Additional costs include multiple SWIFT transfer fees (typically USD 20-50 equivalent per transfer at the sending bank), the currency spread applied to each tranche, and the potential impact of baht appreciation over a 12-24 month schedule.
Can a foreign buyer obtain a mortgage from a Thai bank?
Access is very limited. A small number of banks operating in the region offer mortgage products to foreigners, but these require documented income in Thailand or an ASEAN country, a down payment of 30-50%, and acceptance of the specific project by the lender. For buyers with no Thai-source income, this option is in practice unavailable.
What happens if a buyer misses an instalment payment in Phuket?
The standard contractual penalty is 1-2% per month on the overdue amount. After 30-60 days of non-payment the developer is typically entitled to terminate the contract and retain 25-50% of all funds paid. Penalty and termination clause wording varies by project, so independent legal review before signing is particularly important here.
Are instalment plans available on Koh Samui as well?
Yes, though the offering is narrower than in Phuket. As of 2026, we monitor several condominium projects in Bophut and Maenam with construction-phase instalment schedules of 12-18 months. Terms are broadly similar to Phuket, though final-payment tranches can be higher, reaching 60-70% of the purchase price. The Koh Samui villa market operates predominantly on leasehold structures, where instalment mechanics differ and FET requirements do not apply in the same way.
Is it worth using a currency broker instead of a retail bank for SWIFT transfers?
Based on the rate comparisons in our data sets, specialist currency platforms typically offer spreads of 0.3-0.8% on THB pairs, compared with 1.5-3.5% at retail banks. On a transaction equivalent to 5,000,000 THB the saving can be meaningful in absolute terms. Buyers should confirm that the transfer routed via a currency broker reaches a Thai bank in foreign currency with the correct reference, so that a valid FET can be issued.
