Off-Plan Property Payment Terms in Thailand: 2026 Guide
By THAI.ESTATE Editorial Team13 min read
Buying off-plan property in Thailand means you pay for a unit that does not yet exist in finished form. Your money moves to the developer in stages, and the developer uses that cash flow to fund construction. Understanding exactly how those payment stages work - and where your capital sits at risk at each point - is the most important financial exercise you will do before signing anything.
Thailand has no mandatory escrow mechanism for foreign residential buyers. There is no government-backed account holding your money until a construction milestone is certified. Your protection comes from three things: the shape of the payment schedule, the quality of the contract clauses, and the track record of the developer. This guide breaks down all three.
Quick answer
- Typical payment structure: reservation deposit (2-5%), contract signing (20-30%), construction milestones (30-40% spread across 3-6 draws), handover (15-25%)
- Capital at risk peaks at roughly 55-75% of purchase price during the mid-construction phase, before the final milestone payment
- No escrow for foreign buyers in Thailand; contract terms and developer credibility are the primary safeguards
- Off-plan discount vs completed stock: indicatively 10-20% below comparable completed units as of 2026 market estimates, depending on location, developer tier and construction stage
- Completion guarantees and delay penalty clauses vary widely; they are negotiable before signing, rarely standardized after
- Assignment rights (reselling your contract before completion) must be explicitly written into your purchase agreement - they are not automatic
Options and scenarios
Scenario 1: Standard staged schedule from a mid-tier developer
This is the most common structure you will encounter at a mid-range condominium project in Phuket, Chiang Mai or the Bangkok suburbs. Prices in this segment typically run THB 3-8 million per unit as of 2026 market estimates.
A typical breakdown on a THB 5,000,000 unit looks like this:
- Reservation deposit: 2% = THB 100,000. Paid on the day you express intent. Often non-refundable if you walk away without cause. Refundable (in a well-drafted contract) if the developer fails a condition.
- Contract signing (within 30 days): 25% = THB 1,250,000. This is your largest single payment. It is also the payment that creates the binding obligation. You must have your Foreign Exchange Transaction (FET) form - a bank document proving you sent funds from abroad in foreign currency - prepared for this remittance if you intend to hold a foreign-quota condominium unit under the Condominium Act B.E. 2522 (1979, as amended).
- Foundation and structure milestones (months 6-18): 30% in 3 equal draws = THB 500,000 each. Each draw is triggered when the developer notifies you of a completed construction stage. Inspect the contract: who certifies the stage? An independent engineer, or the developer's own team?
- Fit-out and finishing (months 18-30): 10% = THB 500,000
- Handover: 25% = THB 1,250,000. Paid on the day you receive keys and inspect the unit. This is your last point of leverage.
Capital at risk curve: After contract signing you have transferred THB 1,350,000 (27%). After the third construction draw you have transferred THB 2,850,000 (57%). Your risk peaks at 57% before the final handover payment gives you physical possession.
Scenario 2: Aggressive front-loaded schedule (red flag)
Some smaller or less established developers request 50% or more by the contract-signing stage. The commercial logic is that they need early cash to start breaking ground. The buyer's logic should be skepticism. A schedule that asks for 50% before a single column is poured places the majority of your money at risk before you have any evidence of construction progress.
If a developer insists on this structure, the contract must compensate with very strong completion guarantees, a credible refund mechanism, and ideally a corporate guarantee from a parent company. If none of those exist, this is a meaningful risk signal.
Scenario 3: Deferred or installment-friendly schedule (buyer-favorable)
Established, publicly listed Thai developers and some international-brand projects offer payment terms that keep more capital in your hands longer. A buyer-favorable schedule might look like:
- Reservation: 2%
- Contract signing: 15%
- Four construction milestones: 8% each (32% total)
- Pre-handover inspection: 6%
- Handover: 45%
Here, your capital at risk peaks at roughly 55% at the pre-handover stage, and you retain 45% as leverage until you physically receive a completed, inspected unit. That 45% final payment is real leverage: if the unit has defects or the developer has not met specification, you negotiate before you pay it.
Scenario 4: Assignment before completion
You buy off-plan, the market moves in your favor during construction, and you want to resell the contract before handover rather than completing the purchase. This is called assignment or a novation of contract.
Assignment requires an explicit clause in your original purchase agreement. Without that clause, the developer can refuse to recognize the transfer. With the clause, a typical assignment involves:
- Written developer consent (sometimes a fee of 1-3% of unit price)
- A new buyer who takes on all remaining payment obligations
- Your profit (if any) calculated as: resale price minus your total payments to date minus assignment fee minus any Thai taxes on the gain
Assignment is not guaranteed. In a slow market, finding an assignee at a price above your entry cost may be difficult. Treat assignment as a possible exit path, not a reliable one.
Off-plan discount math: is the risk worth it?
The financial argument for buying off-plan is price. As of 2026 market estimates, a new off-plan condominium in Phuket or Bangkok at project launch is priced approximately 10-20% below a comparable completed and registered unit in the same submarket. On a THB 5,000,000 unit, that is a discount of THB 500,000 to THB 1,000,000.
Set against that discount is the fact that you carry a growing capital-at-risk balance for 2-4 years, you receive no rental income during construction, and you face the possibility - however small with a credible developer - of delay or default.
A simple way to think about it:
- Indicative discount: THB 500,000-1,000,000 on a THB 5M unit
- Opportunity cost of capital at risk (mid-construction, ~THB 2.8M at risk, 3 years, indicative 4% alternative return): approximately THB 336,000
- Net financial advantage if everything goes to plan: roughly THB 164,000-664,000 before any price appreciation
That net advantage disappears quickly if the project is delayed 12-24 months, if your unit is not built to specification, or if you need to exit and cannot find an assignee.

Risks and mistakes
Mistake 1: Not reading the completion guarantee clause
Many off-plan contracts in Thailand contain a completion guarantee that is weaker than the phrase suggests. Read the clause carefully. A genuine completion guarantee specifies: a longstop completion date, a clear consequence if that date is missed (usually a refund right or a penalty), and the financial entity standing behind the obligation. If the clause says 'the developer will endeavor to complete' without a date or a penalty, it is not a guarantee - it is a wish.
Mistake 2: Ignoring the delay penalty rate
Some contracts include a delay penalty payable by the developer to the buyer for each day or month of delay beyond the agreed handover date. Typical rates in Thai off-plan contracts range from 0.01% to 0.1% of the unit price per day, per market estimates. On a THB 5M unit, 0.01% per day is THB 500 per day - a modest sum that does not compensate you for a 12-month delay. Before signing, ask whether the penalty rate is negotiable and whether it is capped.
Mistake 3: Paying without a correct FET form
Foreign buyers purchasing a condominium unit in the foreign quota (the 49% of any building's total floor area that non-Thai nationals can hold in freehold) must prove that each payment was remitted from abroad in foreign currency. The bank issues a Foreign Exchange Transaction (FET) form - sometimes called a Thor Tor 3 form - for each transfer. Without FET forms for every payment, the Land Department will not register the unit in your name on the chanote (the official title deed). Missing FET documentation is one of the most common and avoidable problems for foreign buyers.
Mistake 4: Assuming the developer will refund you if things go wrong
If a developer defaults mid-build, your legal position depends almost entirely on what your purchase agreement says. Thailand has no equivalent of a mandatory developer insolvency protection fund for residential buyers. In practice, a developer insolvency during construction typically leads to one of three outcomes: a new developer takes over the project (your contract may or may not be honored), a court process that can take years, or a partial settlement. Buyers who paid 60-70% of the purchase price before a developer default have the most to lose and the least leverage.
Mistake 5: Signing without independent legal review
The purchase agreement (sometimes called a sale and purchase agreement or SPA) is a Thai-language document. Reputable developers provide an English translation, but the Thai version is the legally binding one. You need a Thai-licensed lawyer - engaged by you, not recommended by the developer - to review both versions before you sign anything beyond the reservation form. Legal fees for this review are typically THB 15,000-40,000, a fraction of your downside risk.
Mistake 6: Not checking developer track record and project title deed status
Before signing, verify two things. First, does the developer have a demonstrable history of completing and delivering projects on time? Ask for references - completed buildings, not brochures. Second, does the project land already hold a clean title deed (chanote), and has the developer applied for or received the Environmental Impact Assessment (EIA) approval and the construction permit? A project selling units on land that does not yet have a construction permit carries meaningful legal risk.
Mistake 7: Treating assignment as a guaranteed exit
See Scenario 4 above. Assignment is possible but not certain. Market conditions, developer approval requirements, and the absence of a clear assignment clause in your contract can all block this exit path.
FAQ
What is a typical payment schedule for off-plan property in Thailand?
A standard schedule runs: reservation deposit (2-5%), contract signing (20-30%), three to six construction milestone payments (30-40% in total), and a final handover payment (15-25%). The exact percentages vary by developer, project size, and how much the buyer negotiates before signing.
Is there an escrow account protecting my payments in Thailand?
No. There are no escrow accounts for foreign residential property buyers in Thailand in the traditional sense. Your protection comes from the payment schedule structure (keeping as much money as possible in your hands until milestones are met), the specific clauses in your purchase agreement, and your assessment of the developer's financial standing and track record.
What is a FET form and why does it matter for off-plan purchases?
A Foreign Exchange Transaction (FET) form, sometimes called a Thor Tor 3 form, is issued by a Thai bank when you receive a foreign-currency transfer from abroad. You need one for every payment you make toward a foreign-quota condominium unit. Without FET documentation covering the full purchase price, the Land Department will not register the property in your name on the chanote (the official title deed). Request the FET form from your Thai bank immediately after each transfer.
What happens if the developer does not complete the project?
Your rights depend on your purchase agreement. If the contract contains a clear completion deadline and a refund right, you can demand your money back - though collecting it from a financially distressed developer is a different matter. Thailand has no mandatory developer insolvency protection fund. In a developer default, buyers typically join other creditors in a court process that can take years. This is why the payment schedule shape matters: the less you have paid before completion, the less you lose if things go wrong.
Can I sell my off-plan unit before construction is finished?
Yes, if your purchase agreement includes an assignment clause. Assignment means transferring your contract rights and obligations to a new buyer. The developer must usually give written consent, and may charge a fee (often 1-3% of unit price). Without an explicit assignment clause in your contract, the developer can refuse to recognize any transfer.
How much cheaper is off-plan compared to completed property in Thailand?
As of 2026 market estimates, off-plan units at launch are priced approximately 10-20% below comparable completed resale units in the same area. The discount is larger in early-launch phases and narrows as construction progresses and market confidence grows. This discount is the primary financial incentive for accepting the construction and developer risk.
What is a delay penalty clause and should I negotiate one?
A delay penalty clause requires the developer to pay you a daily or monthly sum if handover is delayed beyond the agreed date. Typical rates per market estimates range from 0.01% to 0.1% of the unit price per day. You should request a penalty clause if one is not already in the contract, and push for a rate that meaningfully compensates you for the cost of delay - including loss of rental income and extended financing costs.
What due diligence should I do before paying a reservation deposit?
Before paying any money: confirm the project land title is a chanote; verify that a construction permit has been issued or applied for; check the EIA approval status if the project is large enough to require one; research the developer's completed projects; and have a Thai-licensed lawyer (engaged by you) review the reservation form. The reservation deposit is often non-refundable, so treat this stage as a commitment, not a trial.
What is the foreign quota for condominiums in Thailand?
Under the Condominium Act B.E. 2522 (1979, as amended), foreign nationals can hold freehold ownership of up to 49% of the total floor area of a registered condominium building. This is called the foreign quota. If the foreign quota in your chosen project is full, you cannot hold the unit in freehold as a foreign buyer - only through leasehold or a Thai-company structure, each with its own legal and practical implications.
Should I use the developer's recommended lawyer?
No. A lawyer recommended and sometimes paid by the developer has an inherent conflict of interest. Engage your own Thai-licensed lawyer independently. Ask them to review the purchase agreement in both Thai and English, confirm the title deed status, and check whether the developer's company registration and construction permits are in order. Legal fees for this service are a small cost relative to the purchase price and the risk involved.
