Off-plan payment schedule Thailand: how foreign buyers pay safely in 2026
By THAI.ESTATE Editorial Team15 min read
Foreign buyers purchasing off-plan property in Thailand do not pay the full price upfront. Instead, you spread payments across construction milestones over 12 to 36 months, typically starting with a 10-30% deposit and finishing with the balance on handover. This staged payment schedule is your primary risk-management tool in Thailand, because there are no escrow accounts for foreign real estate buyers in the traditional sense. Your safety comes from the contract terms, the developer's financial health, and limiting the percentage you pay before the building is complete.
A typical off-plan payment structure in Thailand as of 2026 follows a 5-7 stage model tied to physical construction progress. The most common schedule asks for 20-30% before construction starts (reservation plus contract signing), then 40-50% in staged payments linked to foundation, structural frame, roof completion, and interior fit-out milestones, and the final 30-40% at handover when the developer delivers the keys and the title transfer can occur. The exact percentages and timing vary by developer and project scale, but this structure means you carry the most capital risk in the middle of the build when 50-70% of the purchase price is already paid but the property cannot yet generate rental income or be resold easily.
The off-plan discount versus completed resale stock in the same area typically ranges from 15% to 30% as of 2026, according to market estimates. A Phuket sea-view condo priced at 8 million baht off-plan might trade at 10-11 million baht once completed and fitted. That 2-3 million baht discount is the reward for carrying construction risk over 18-24 months. You need to weigh this price advantage against the exposure: if the developer delays or defaults when you have already paid 60% of the purchase price, you face a legal battle to recover funds, and Thai contract law does not guarantee full refunds.
Quick answer
- Off-plan payment schedules in Thailand spread the purchase price over 5-7 milestones tied to construction stages, typically 12-36 months
- Most common structure: 20-30% upfront (reservation plus contract), 40-50% during construction milestones, 30-40% at handover
- There are no escrow accounts for foreign buyers in Thailand. Your protection is the contract terms, the milestone schedule shape, and the developer's track record
- The off-plan discount versus completed resale stock ranges from 15-30% (market estimates, 2026), compensating for the risk you carry while the building is under construction
- Contract clauses for completion guarantees, delay penalties, and refund conditions are the safety mechanisms you negotiate. Default wording often favors the developer
- Your peak capital exposure occurs mid-build when you have paid 50-70% but the property is not yet habitable or easily resold
Options and scenarios
The payment schedule structure changes your risk profile and liquidity needs. Developers offer different schedule shapes depending on project type, location, and their own cash flow requirements. A large Bangkok high-rise from a listed developer might offer a conservative schedule with only 10% due before ground is broken, while a boutique Samui villa project from a smaller firm might ask for 40% upfront to fund land costs and initial works. You need to match the schedule to your risk tolerance and access to capital.
Early-heavy schedule (30-40% upfront, balance back-loaded): This structure asks for a large deposit at contract signing, then smaller payments during construction, with 30-40% remaining at handover. Developers use this model to secure early funding without bank construction loans. For you, the risk is immediate: if the project stalls after foundation stage, you have 40% of your capital locked in with limited recourse. The upside is a steeper discount, often 20-30% below completed market value, because the developer rewards the early cash injection. This schedule suits buyers with strong liquidity who have done deep due diligence on the developer's financials and construction track record.
Milestone-matched schedule (20% upfront, 50% during build, 30% at handover): This is the most common structure in Thailand as of 2026 for mid-market condos. You pay a reservation fee (50,000-200,000 baht, refundable in some contracts, non-refundable in others), then 15-20% at contract signing, then 8-12% at each of 4-5 construction milestones (foundation complete, structure to 50%, structure topped out, windows and facade done, interior fit-out complete), and 30% at handover when the ownership transfer occurs at the Land Office. Your capital exposure grows gradually and peaks just before completion. This schedule gives you multiple decision points: at each milestone payment, you can inspect progress and assess whether the project is on track before releasing the next installment. The challenge is that most contracts do not grant you a unilateral right to withhold payment if you are unhappy with progress; the contract will define what constitutes milestone completion, and disputes go to arbitration.
Back-loaded schedule (10% upfront, 40% during build, 50% at handover): Some large developers with strong balance sheets offer schedules that defer the majority of payment until handover. This structure minimizes your risk during construction because you retain control of 50% of the purchase price until the property is ready. The trade-off is a smaller discount, typically 10-15% below completed market value, because the developer is extending you credit and carrying the construction risk on their books. This schedule is rare and usually appears on projects from developers who do not need buyer funds to finance construction, often listed companies with bank credit lines. For foreign buyers, this is the safest payment structure if you can find it, but the price advantage over buying completed stock is marginal.
Assignment as an exit path: Most off-plan contracts in Thailand allow you to assign (resell) your contract to another buyer before completion, subject to developer approval and a transfer fee (typically 1-3% of the purchase price). This means if you have paid 50% by milestone four and the market has moved in your favor, you can sell the contract at a markup and exit before handover. The assignment clause is critical for liquidity: it converts an illiquid construction-stage commitment into a tradable asset. However, the developer retains approval rights, and in a down market, you may struggle to find a buyer willing to take over the remaining payment obligations. Always confirm the assignment clause allows transfer to foreigners (some contracts restrict assignment to Thai nationals only, which kills your exit options).

Risks and mistakes
No escrow protection for foreign buyers: The single biggest misconception among foreign buyers is that off-plan payments in Thailand go into an escrow account until the property is delivered. This is false. There are no escrow accounts for foreign real estate buyers in Thailand in the traditional sense. When you transfer funds to the developer at each milestone, that money enters the developer's operating account and is used to fund construction, service debt, or cover overheads. If the developer defaults, you become an unsecured creditor competing with the bank (which holds a mortgage over the land) and other creditors. The contract may promise a refund in case of non-delivery, but enforcing that promise requires legal action, and recovery rates for foreign buyers in Thai developer bankruptcies are poor (often 20-40% of amounts paid, settled years later).
Vague milestone definitions: Many off-plan contracts define milestones in subjective language: 'structure substantially complete', 'interior works in progress'. This vagueness lets the developer trigger the next payment even if the physical work is delayed or substandard. You need to negotiate objective milestone definitions tied to verifiable events: 'foundation poured and inspected by structural engineer', 'certificate of occupancy issued by the district office', 'individual electricity meter installed and activated'. Attach photographic evidence requirements to each milestone and reserve the right to inspect before payment. Developers resist this level of detail, but it is the only way to prevent paying for work not yet done.
Weak delay penalty clauses: The standard developer contract in Thailand as of 2026 includes a delay penalty clause, but the rates are often negligible: 0.01-0.05% of the purchase price per day of delay, capped at 5-10% total. On an 8 million baht condo, a 90-day delay at 0.01% per day yields a 72,000 baht penalty, which does not compensate you for three months of lost rental income (which could be 120,000-150,000 baht at typical Phuket yields). Worse, the clause usually allows the developer to extend the completion date for force majeure events (weather, labor shortages, government delays), and the definition of force majeure is broad and unilateral. You need to negotiate a higher daily rate (0.05-0.1%) and a cap of 15-20%, and narrow the force majeure definition to exclude routine construction risks.
No buyer exit without forfeiture: Most contracts do not grant you the right to cancel and receive a refund if you simply change your mind or find the project is progressing poorly. The standard clause states that if you fail to make a scheduled payment, the developer can terminate the contract and forfeit all amounts already paid. This means if you have paid 60% and decide to walk away at milestone five because construction quality is substandard, you lose the 60% (4.8 million baht on an 8 million baht purchase). The developer may offer to refund a portion (50-70% of amounts paid) if they can resell the unit, but this is a discretionary gesture, not a contractual right. To protect yourself, negotiate a buyer cancellation clause that allows you to exit with a defined penalty (e.g., forfeit 10-15% of total price, receive the rest back within 90 days). Few developers agree to this, which tells you that the contract is one-sided.
Currency risk on staged payments: If you are funding the purchase from foreign currency (USD, EUR, GBP), you face exchange rate exposure over the 18-24 month payment period. A 10% depreciation of your home currency against the baht between contract signing and final payment increases your effective cost by 3-4% of the purchase price (since 30-40% is paid at the end). Hedging this risk with forward contracts or paying the full amount upfront in baht (and forgoing the schedule) creates other problems (counterparty risk, loss of milestone leverage). The practical answer is to budget a 10-15% currency buffer on the final payment and accept the risk, or choose a back-loaded schedule that defers the bulk of payment to a single future date that you can hedge.
Ignoring the developer's capital structure: The payment schedule only protects you if the developer has the capital to complete the project even if some buyers default on their payments. A developer funding construction entirely from buyer payments (no bank loan, no equity buffer) is a high-risk counterparty: if 10% of buyers default or delay, the project stalls. You need to verify the developer's funding structure before signing: ask for evidence of a bank construction loan (which proves the bank has underwritten the project), ask what percentage of units must be sold to break even (below 50% is safer), and check if the developer has other completed projects generating cash flow. A developer with three ongoing projects and no completed track record is burning cash and poses a default risk, regardless of the payment schedule.
Overlooking the assignment clause for exit liquidity: If you do not confirm that the contract allows assignment to another buyer, you have no exit path before completion. Some contracts prohibit assignment entirely, or allow it only with developer consent (which can be withheld arbitrarily), or charge a transfer fee so high (5-10% of purchase price) that reselling becomes uneconomic. The assignment clause should explicitly permit transfer to foreign buyers (Thai contracts sometimes restrict assignment to Thai nationals), state the transfer fee (1-3% is market standard), and specify the approval process (developer consent not to be unreasonably withheld, decision within 14 days). Without these terms, you are locked in until handover.
FAQ
What percentage do you pay upfront when buying off-plan in Thailand?
You typically pay 20-30% of the purchase price before construction starts, split between a reservation fee (50,000-200,000 baht) and a contract signing payment (15-25% of total price). The exact percentage depends on the developer and project type. Larger, established developers may ask for only 10-15% upfront, while smaller firms or boutique projects often require 30-40% to fund initial works.
Are off-plan payments held in escrow in Thailand?
No. There are no escrow accounts for foreign real estate buyers in Thailand in the traditional sense. Payments go directly to the developer's operating account and are used to fund construction and business operations. If the developer defaults, you become an unsecured creditor and must pursue legal remedies to recover funds, which is slow and often results in partial recovery only.
How do construction milestone payments work in a Thai off-plan contract?
Milestone payments are triggered when the developer completes a defined stage of construction, such as foundation complete, structure topped out, or interior fit-out done. The contract specifies the percentage due at each milestone (typically 8-12% per stage) and the completion criteria. The developer notifies you that a milestone is reached, you inspect (if the contract allows), and you must pay within a set period (usually 14-30 days). Failure to pay on time can result in contract termination and forfeiture of amounts already paid.
What happens if the developer delays completion in Thailand?
The contract will include a delay penalty clause, typically 0.01-0.05% of the purchase price per day of delay, capped at 5-10% total. The developer can extend the completion date for force majeure events (weather, government delays, labor shortages), which are broadly defined. If the delay is excessive (6-12 months beyond the extended date), you may have the right to cancel and request a refund, but enforcement requires legal action, and the refund is not automatic.
Can you resell an off-plan contract before completion in Thailand?
Most contracts allow assignment (resale of the contract) to another buyer before completion, subject to developer approval and a transfer fee (1-3% of purchase price). This gives you an exit path if you need liquidity or if the market has moved in your favor. However, the developer retains the right to approve the new buyer, and in a down market, finding a buyer willing to take over the remaining payments can be difficult. Always confirm that the assignment clause permits transfer to foreigners.
What is a safe off-plan payment schedule for foreign buyers in Thailand?
A safe schedule minimizes your capital at risk during construction. Look for a structure that pays no more than 20% before construction starts, spreads 40-50% across verifiable construction milestones, and retains 30-40% until handover. Avoid schedules that ask for 40% or more upfront, as these lock in too much capital before you can assess construction progress. The safest option is a back-loaded schedule (10% upfront, 50% at handover), but these are rare and offer smaller discounts.
How much discount do you get buying off-plan versus completed property in Thailand?
The off-plan discount versus completed resale stock in the same area ranges from 15-30% as of 2026, based on market estimates. The discount compensates you for carrying construction risk and waiting 12-36 months for delivery. Prime Bangkok locations may show only 10-15% discount, while secondary markets like Hua Hin or Chiang Mai can offer 25-30%. The discount narrows as construction progresses: by the time the building is 80% complete, off-plan units may trade at only 5-10% below completed comparable sales.
What contract clauses protect foreign buyers in Thai off-plan deals?
Key protective clauses include: objective milestone definitions tied to verifiable completion events, a delay penalty clause with a daily rate of 0.05-0.1% and a cap of 15-20%, a buyer cancellation clause allowing exit with a defined penalty (10-15% forfeiture), an assignment clause permitting transfer to foreign buyers with a reasonable fee (1-3%), and a refund clause specifying the process and timeline if the developer fails to deliver. Standard developer contracts rarely include all these terms, so you need to negotiate.
Do you pay property tax during the off-plan construction period in Thailand?
No. Property tax in Thailand (land and building tax) is assessed on the owner of record as of January 1 each year. Until you complete the ownership transfer at handover, the developer remains the legal owner and pays any applicable tax. You begin paying property tax the year after you take ownership. However, you may be responsible for common area fees or sinking fund contributions from the handover date, even if you do not occupy the unit immediately.
What due diligence should you do on the developer before committing to an off-plan payment schedule?
Verify the developer's completed project track record (visit previous projects, check handover dates versus promised dates), confirm the existence of a bank construction loan (ask for a letter from the lending bank), review the project's pre-sale figures (below 50% sold is a red flag for cash flow), check the developer's legal structure (Thai limited company, check shareholder composition and debt levels at the Department of Business Development), and search for any legal disputes or complaints filed by previous buyers. Engage a Thai lawyer to review the sales contract clause by clause before you pay the reservation fee.
Your safety in a Thai off-plan purchase comes from three layers: a payment schedule that limits your capital at risk before completion, contract clauses that give you leverage and exit options, and a developer with the financial strength and track record to deliver on time. The schedule shape is negotiable, especially on larger purchases or when buying multiple units. Push for a milestone-matched or back-loaded structure, verify every completion trigger, and never assume that the standard contract protects your interests. The developer's standard terms are written to protect the developer. Your job is to rebalance the risk before you pay the first installment.
