Paying for an Under-Construction Condo in Thailand: 2026 Guide
By THAI.ESTATE Editorial Team14 min read
Buying an off-plan condo in Thailand means you pay in stages over the construction period, not as a lump sum at the end. The developer holds your money during the build. There is no government-mandated escrow protection for foreign buyers in Thailand, so the safety of your capital depends almost entirely on the contract terms you negotiate, the developer's track record, and how the payment schedule is structured.
The honest answer first: an off-plan condo in a reputable Thai project can offer a price that is 10-25% below comparable completed stock (indicative, as of 2026, based on market estimates for Phuket and Bangkok). You earn that discount by carrying construction risk. This guide shows you exactly how that risk is shaped by the payment schedule, the contract clauses, and the actions you take before signing.
Quick answer
- No escrow for foreign buyers. Thailand has no standard escrow mechanism protecting off-plan payments for foreign retail buyers. Your protection is the contract and developer credibility.
- Typical staged payments: reservation fee (1-3%), signing (20-30%), construction milestones (30-40% spread across several draws), and handover balance (25-35%).
- The shape of the schedule matters. A front-loaded schedule (60%+ due before structural completion) maximises your capital at risk early. A back-loaded schedule (40%+ at handover) keeps more leverage with you.
- Completion guarantees are rare in standard Thai developer contracts. What you can negotiate is a delay penalty clause and a clear definition of what triggers buyer exit rights.
- Foreign buyers must pay for condominium units from abroad in foreign currency, converted through a Thai bank, to satisfy the FET (Foreign Exchange Transaction) requirement - the record that proves your funds came from overseas and allows you to repatriate later.
- Off-plan discount vs. completed resale (indicative, 2026): 10-25% lower price per square metre, in exchange for 18-48 months of construction exposure.
- Assignment (reselling your purchase contract before handover) is possible but contractually restricted in most Thai developments. Expect a transfer fee of 1-3% of the contract value payable to the developer.
Options and scenarios
Scenario 1: Standard market-rate off-plan schedule
The most common structure seen in Thai condominium projects in 2026 looks like this:
- Reservation deposit: 50,000-200,000 THB (roughly 1,300-5,500 USD at current rates), paid to secure the unit and take it off sale. This is often non-refundable if you do not proceed to contract.
- Contract signing (within 30-45 days of reservation): 20-30% of the purchase price.
- Construction milestone 1 (foundation complete): 10-15%
- Construction milestone 2 (structural frame complete): 10-15%
- Construction milestone 3 (building enclosed / fit-out begins): 10%
- Handover (transfer of title): 25-35%
With a 3,000,000 THB unit on this schedule, your capital at risk peaks somewhere between milestone 2 and milestone 3, when you have paid roughly 55-70% of the price. At that point the building exists physically, which reduces default risk somewhat, but you have no title document yet.
Scenario 2: Developer-favoured front-loaded schedule
Some developers, particularly smaller operators or those with tight project financing, ask for 70-80% by the time the structure is enclosed. This means you have paid most of the price before the interior fit-out begins. Your leverage at handover drops significantly. If the developer delays or defaults at the fit-out stage, you have little financial pressure to apply.
This is a warning sign. If a payment schedule puts more than 65% of the price before structural completion, negotiate a rebalancing toward handover, or treat it as elevated risk.
Scenario 3: Back-loaded, buyer-friendly schedule
Larger, listed Thai developers and projects with institutional backing sometimes offer a structure where 35-40% is held back until handover. In some cases, the balance is split between practical completion and title transfer. This is the most protective structure for you as a buyer. The developer has a strong financial incentive to finish on time and to a specification that passes your inspection.
A 35% handover payment on a 5,000,000 THB unit means 1,750,000 THB of leverage at the critical moment. That is a meaningful contractual tool.
Scenario 4: Extended payment plan with post-handover instalments
A smaller number of Thai developers, primarily in Phuket and Pattaya, offer post-handover payment plans: you take title, move in or rent the unit, and continue paying instalments for 12-36 months after handover. This structure is usually priced at a premium above the standard off-plan price (developers charge for the financing risk). It reduces your pre-completion exposure but increases total cost.
Off-plan price discount versus completed resale: the numbers
Consider two comparable 50 sqm condominiums in the same area of Phuket (indicative figures, Q1 2026 market estimates):
- Completed resale unit: 6,500,000 THB (130,000 THB/sqm). Ready to rent immediately, title transferable now, no construction risk.
- Off-plan unit in an equivalent project, 24 months from handover: 5,200,000 THB (104,000 THB/sqm). That is a 1,300,000 THB saving, or 20% below resale.
But that 1,300,000 THB saving comes with a cost: you carry 24 months of construction risk. Your maximum capital at risk (at milestone 2, roughly 65% paid) is approximately 3,380,000 THB, tied up in an asset you cannot yet title, rent, or sell cleanly.
The break-even question is: what do you lose if the project is delayed by 12 months? If your unit would have generated 25,000 THB/month in rent, a 12-month delay costs you 300,000 THB in lost income. The discount still holds, but it narrows.
If the project is abandoned mid-build - a rare but real scenario in Thailand - recovery through Thai courts is slow and uncertain. Partial refunds through civil litigation can take years. The discount does not compensate for a total loss.

Contract protections: what to check clause by clause
Completion guarantee
Most standard Thai developer contracts do not include a bank-backed completion guarantee. What you can sometimes negotiate is a longstop date - a specific calendar date by which the unit must be ready for handover. If that date is missed, a defined remedy applies. Without a longstop date, the contract may only say the project will complete 'approximately' within a stated period, which gives you almost no legal leverage.
Before signing, have a Thai property lawyer (one independent of the developer) review the completion and delay clauses specifically.
Delay penalty clauses
A well-drafted delay penalty clause specifies a fixed amount per day or per month of delay, payable by the developer to you. Common indicative figures in negotiated Thai contracts: 0.01-0.05% of the purchase price per day of delay beyond the longstop date. On a 5,000,000 THB unit, that is 500-2,500 THB per day. After 90 days of delay, you would have a claim of 45,000-225,000 THB. This is a deterrent, not full compensation.
Check whether the delay penalty is capped (many developers cap it at 5-10% of the price) and whether force majeure events (floods, pandemics, regulatory delays) suspend the penalty period. Force majeure clauses in Thai contracts have historically been written broadly.
Buyer exit and refund conditions
Your right to exit and receive a refund is only as strong as the specific contract language. Look for:
- A clear trigger for buyer termination (for example, delay exceeding a stated number of months)
- A stated refund amount and timeline (for example, '100% of all instalments paid, within 60 days of written notice')
- Whether the reservation deposit is included in the refund or excluded as non-refundable
- Whether the refund is in Thai baht only (currency risk on repatriation)
Many standard Thai developer contracts allow the developer to terminate for non-payment by the buyer (with penalty deductions of 10-30% of paid instalments), but give the buyer exit rights only in narrow circumstances. This asymmetry is a real risk. Negotiate symmetrical exit rights.
What happens if the developer defaults mid-build
If a developer becomes insolvent mid-construction, the practical outcome for you as a foreign buyer in Thailand is difficult. There is no insurance fund or government compensation scheme. Your legal position is that of an unsecured creditor in a Thai civil or bankruptcy proceeding. Recovery rates in Thai developer insolvencies have varied widely; some buyers recover 30-50 cents on the baht, some recover less, over a period of years.
The mitigation: buy from developers with a completed project history, verified land title (the land under the project should be held under a chanote - a full-title land certificate, the highest class of land title in Thailand - not a lesser Nor Sor 3 document), and no reported disputes with previous buyers.
Assignment as an exit path
If you want to exit before handover - whether for profit or to cut a loss - assignment (transferring your purchase contract to a new buyer) is the most practical route. Most Thai developer contracts permit this but require:
- Developer written consent (sometimes withheld at developer discretion)
- An assignment fee: typically 1-3% of the original contract value, payable to the developer
- The new buyer meeting any nationality requirements for foreign quota units
Assignment profit depends on market movement since you signed. In a rising market, buyers have sold assigned contracts at 5-15% above their purchase price, net of the assignment fee. In a flat or declining market, assignment at a loss is also possible. Assignment does not guarantee exit.
The FET requirement for foreign buyers
Foreign buyers purchasing a condominium unit in Thailand (under the Condominium Act, which allows foreigners to own up to 49% of the total area in a building) must prove that each payment was remitted from abroad in foreign currency. The receiving Thai bank issues a Foreign Exchange Transaction form (FET) for amounts of 50,000 USD equivalent or above; for smaller amounts, a credit advice or SWIFT confirmation serves the same purpose.
You must obtain and retain FET documentation for every stage payment. Without it, you cannot register the title in your name at the Land Department, and you cannot repatriate the funds when you sell. This is not optional paperwork - it is a legal requirement under the Condominium Act and the foreign exchange regulations administered by the Bank of Thailand.
Practical implication: never pay instalments in cash, and never route payments through a Thai bank account held in your name (or anyone else's Thai account) as a local transfer. Each payment must arrive from a foreign bank account held in your name, in foreign currency, to a Thai bank account designated by the developer.
Risks and mistakes
Signing without independent legal review. The developer's sales team will provide a standard contract. That contract is written for the developer's benefit. A Thai property lawyer, hired and paid by you alone, costs 15,000-40,000 THB for a contract review. That fee is insignificant compared to the capital you are committing.
Accepting vague completion language. If the contract says 'approximately 24 months' with no longstop date and no penalty clause, you have no enforceable completion date. Insist on a specific calendar date and a penalty for breach.
Ignoring the developer's land title. Ask for a copy of the chanote for the project land before paying any money. If the land is mortgaged to a bank, ask for written confirmation that unit titles will be released from the mortgage at your handover. This is standard practice and a reputable developer will not refuse.
Paying through non-compliant channels. Cash payments, local bank transfers, or payments made through a third party will destroy your FET record. You will be unable to register title. This is an irreversible mistake.
Underestimating the foreign-quota rule. Thai condominiums can only sell up to 49% of the total floor area to foreign buyers. If a project is over-subscribed with foreign buyers, late buyers can be pushed to a Thai-name structure (leasehold or nominee), which carries completely different risks. Confirm your unit is inside the foreign quota before paying the reservation fee.
Treating assignment as a guaranteed exit. Assignment depends on developer consent and market demand. In a project with slow sales or a developer in financial difficulty, finding an assignee at any price may be impossible.
Not retaining FET documents. Keep originals. If they are lost, reconstruction is slow and sometimes impossible. Use a document storage service or photograph and cloud-store everything immediately.
FAQ
How does an off-plan payment schedule work in Thailand?
You pay in stages linked to construction progress, not in one sum. A typical schedule starts with a reservation deposit (1-3%), then a signing payment (20-30%), several milestone payments during construction (30-40% in total), and a final balance at handover (25-35%). Each payment is contractually tied to a stage of the build.
Is there escrow protection for off-plan buyers in Thailand?
No. There is no government-mandated or industry-standard escrow mechanism protecting foreign off-plan buyers in Thailand. Your protection comes from the contract terms, the developer's financial position and track record, and the structure of the payment schedule itself. Always prioritise back-loaded schedules and strong contract exit clauses.
What is an FET form and why does every payment require one?
A Foreign Exchange Transaction form (FET) is issued by a Thai bank when it receives an international wire transfer in foreign currency. It proves that your funds came from outside Thailand. Under the Condominium Act, you must hold FET documentation for every payment to register title in your name and to repatriate sale proceeds later. Every instalment must be wired from your overseas bank account in foreign currency.
What happens if the developer goes bankrupt before my unit is finished?
You become an unsecured creditor in a Thai civil or bankruptcy proceeding. There is no insurance fund for buyers. Recovery is uncertain and slow. This risk is the core reason to research developer creditworthiness carefully before paying any money, and to prefer back-loaded payment schedules that minimise your exposure during the early construction stages.
Can I resell my off-plan contract before the building is complete?
Yes, through assignment, if your contract permits it and the developer consents. Most Thai developer contracts allow assignment but charge a fee of 1-3% of the contract value and require written developer approval. Profit or loss on assignment depends on market movement since your purchase date.
How much cheaper is an off-plan unit compared to a completed one?
Based on market estimates as of 2026, comparable off-plan units in Phuket and Bangkok are priced approximately 10-25% below equivalent completed resale stock. The gap is larger for longer construction timelines and in markets with active developer competition. This discount compensates you for the construction risk and the time your capital is tied up without generating rental income.
What should I check about the developer before signing?
Verify that the developer has completed at least one prior project on time and to specification. Confirm the project land is held under a chanote (full-title certificate). Check whether the land is mortgaged and that a bank release mechanism exists at handover. Search for any reported buyer disputes in Thai court records or property forums. Have an independent Thai lawyer confirm your findings.
What is the foreign quota rule for Thai condominiums?
The Thai Condominium Act restricts foreign (non-Thai) ownership to a maximum of 49% of the total floor area of any registered condominium building. Units within that 49% are called foreign-quota units. If you buy outside the quota through a Thai leasehold structure, your ownership rights and exit options are significantly different. Always confirm your specific unit is within the foreign quota before making any payment.
How do delay penalty clauses work in Thai off-plan contracts?
A delay penalty clause specifies a sum the developer pays you for each day or month of delay past the longstop date. Typical negotiated rates run from 0.01% to 0.05% of the purchase price per day. Most developers cap total penalties at 5-10% of the price. These clauses act as a deterrent but are rarely full compensation for your costs. Verify that the clause is not suspended by a broadly written force majeure provision.
What is a chanote and why does it matter for off-plan purchases?
A chanote (also written as Nor Sor 4 Jor) is the highest class of land title certificate in Thailand, issued by the Land Department and based on GPS-surveyed boundaries. It is the only land title that supports clean freehold transfer. If the developer's land is held under a lesser title (such as Nor Sor 3), the title upgrade process adds risk and time. Always confirm the project land is under a chanote before signing a purchase contract.
