Off-Plan Payment Schedules in Bangkok: 2026 Guide

Buying off-plan in Bangkok means you pay for a property that does not yet exist. Your money moves in stages, tied to construction milestones, and the shape of that schedule determines how much capital you have at risk at any given moment. Understanding the schedule is the single most practical thing you can do before signing.

This guide breaks down how a typical Bangkok off-plan payment schedule works in 2026, shows you the math on discount versus risk, and explains clause by clause what your contract should say to protect your money.

Quick answer

• A standard Bangkok off-plan schedule runs across 4 to 6 payment stages, from reservation through to handover
• The reservation deposit is typically THB 50,000 to THB 200,000 (roughly USD 1,400 to USD 5,600), paid upfront to hold the unit
• The contract-signing payment (usually within 14 to 30 days of reservation) typically totals 10% to 20% of the purchase price
• Construction milestone payments add another 10% to 30% cumulatively, split across 2 to 4 draw-downs as floors are completed
• The final payment at handover is typically the largest single tranche: 60% to 70% of the total price
• As of 2026, off-plan condominiums in Bangkok are priced at roughly 10% to 20% below comparable completed stock in the same submarket, per market estimates - that gap is the discount you carry risk for
• There are no escrow accounts protecting foreign buyers in Thailand in the traditional sense. Your protection comes from contract terms, milestone linkage, and developer track record

Options and scenarios

Scenario 1: Standard mid-market Bangkok condominium

This is the most common structure for projects from established Thai developers in areas such as Sukhumvit, Rama 9, or Lat Phrao, with a build period of 24 to 36 months.

Example unit price: THB 5,000,000

• Reservation deposit: THB 100,000 (2%) - paid on the day you choose the unit
• Contract signing (30 days later): THB 400,000 (8%) - total at this point: THB 500,000 (10%)
• Foundation complete (month 6): THB 250,000 (5%) - running total: THB 750,000 (15%)
• Structure at mid-rise (month 12): THB 250,000 (5%) - running total: THB 1,000,000 (20%)
• Structure topped out (month 18): THB 250,000 (5%) - running total: THB 1,250,000 (25%)
• Handover (month 30): THB 3,750,000 (75%) - this is typically financed by a Thai bank mortgage if the buyer qualifies, or paid in full from overseas funds via a Foreign Exchange Transaction (FET) certificate

At the riskiest point before handover - month 18 in this example - you have THB 1,250,000 (25% of the purchase price) exposed to developer default. That is your maximum pre-handover exposure in this structure.

A Foreign Exchange Transaction (FET) certificate (sometimes called a Thor Tor 3 form) is a document issued by a Thai commercial bank confirming that foreign currency was brought into Thailand and converted to Thai baht. Foreign buyers of condominiums must obtain this document for the full purchase price to register ownership. You need to plan your fund transfers accordingly.

Scenario 2: Luxury high-rise, longer build cycle

High-end projects (Sathorn, Silom, Wireless Road areas) with 48 to 60-month build periods sometimes use a heavier front-loaded structure to fund construction.

Example unit price: THB 15,000,000

• Reservation: THB 200,000 (1.3%)
• Contract signing: THB 1,300,000 (8.7%) - total: 10%
• Milestone 1 (floor 5 complete): THB 750,000 (5%) - total: 15%
• Milestone 2 (floor 15 complete): THB 750,000 (5%) - total: 20%
• Milestone 3 (floor 25 complete): THB 750,000 (5%) - total: 25%
• Milestone 4 (structure topped out): THB 750,000 (5%) - total: 30%
• Handover: THB 10,500,000 (70%)

Your maximum pre-handover exposure here is 30% of THB 15,000,000, or THB 4,500,000. The longer timeline and multiple draw-downs mean you are exposed for a longer period, which increases the importance of developer track record checks.

Scenario 3: Boutique low-rise project, shorter build

Some smaller Bangkok developers building 8- to 12-floor condominiums complete in 18 to 24 months and use a simpler three-stage schedule.

Example unit price: THB 3,500,000

• Reservation + contract (combined or within 2 weeks): THB 350,000 (10%)
• Structure complete (month 12): THB 350,000 (10%) - total: 20%
• Handover (month 20): THB 2,800,000 (80%)

Here your pre-handover exposure is capped at 20%. The faster build cycle limits time-based risk, but a smaller developer may carry more financial fragility than a listed group. Always check whether the developer has delivered previous projects on time.

Discount versus risk: the core math

The argument for off-plan is price. As of 2026, market estimates suggest a 10% to 20% discount for comparable off-plan versus completed resale stock in Bangkok's mid-market.

Using THB 5,000,000 as the off-plan price:

• Equivalent completed unit in the same building or submarket: approximately THB 5,500,000 to THB 6,000,000
• Your potential discount: THB 500,000 to THB 1,000,000
• Your maximum pre-handover capital at risk (25% in Scenario 1): THB 1,250,000

The discount does not eliminate the risk. If the developer defaults after your milestone payments but before handover, recovering even your deposited funds through Thai courts is a slow and uncertain process. The discount compensates you for carrying that uncertainty. Whether the compensation is sufficient depends on the developer's financial standing and the strength of your contract.

Contract protections: what your agreement should contain

Completion guarantee clause: Your contract should state a specific completion date and what happens if that date is missed. Reputable Bangkok developers include a grace period (commonly 12 months) after which the buyer gains the right to cancel and receive a full refund. Read this clause carefully - some contracts state 'best efforts' language that is not enforceable as a hard deadline.

Delay penalty terms: Some contracts include a daily or monthly penalty (per market practice, figures around 0.01% of the purchase price per day are seen, though this varies) payable by the developer to you for each day of overrun beyond the grace period. This is not universal. If the contract does not include it, you can attempt to negotiate it in before signing.

Buyer exit and refund conditions: Confirm what you forfeit if you cancel voluntarily. Standard Thai developer contracts allow the developer to retain the reservation deposit and sometimes the contract-signing payment if you withdraw without cause. Cancellation due to developer breach should trigger a full refund of all payments made, plus the delay penalty if applicable.

Assignment clause: Assignment means you sell your contractual right to buy the unit to a third-party buyer before construction is complete. Many developers permit assignment, sometimes for a fee of 1% to 3% of the purchase price. Some restrict it entirely to protect their own resale pricing. Check whether your contract allows assignment, what approval process is required, and what fee applies. Assignment is a real exit path in a rising Bangkok market, but it requires a buyer willing to step into your position, and it does not exist as an automatic right.

Developer default: If a developer becomes insolvent mid-build, your recourse under Thai law is to file as an unsecured creditor. Recovery is not guaranteed and timelines extend to years. A juristic person (the legal entity formed by a condominium's co-owners to manage the building after completion) does not exist until the building is registered, so it cannot protect pre-completion buyers. This is why the credibility and financial health of the developer matters more than any single contract clause.

Sinking fund and common area fees: At handover you will typically pay a one-time sinking fund (a reserve for major future repairs, usually THB 400 to THB 700 per square metre as of 2026, per market estimates) and start paying ongoing common area management fees (typically THB 40 to THB 80 per square metre per month). These are not part of the payment schedule but affect your total cost at handover.

Chanote title deed: A chanote is Thailand's highest-grade land title document, showing GPS-verified boundaries. Confirm before signing that the project will be registered with chanote title. Some older Bangkok projects used lesser title types; a chanote is the standard for new condominium developments.

Risks and mistakes

Paying more than the milestone justifies. Some contracts front-load payments so that 30% or 40% is paid within the first six months, long before structural work proves the project is viable. A front-loaded schedule benefits the developer, not you. Negotiate for milestone linkage - each payment should correspond to a verifiable construction event.

Not verifying the developer's title to the land. Before a Bangkok developer can legally sell off-plan condominiums, they must register the project with Thailand's Real Estate Information Center and hold the land under chanote title. Ask to see proof of land ownership and the project's Environmental Impact Assessment (EIA) approval. If a developer cannot show these, do not proceed.

Assuming the contract is standard. Thai property contracts are not standardised by law in the way some countries regulate them. Every clause is negotiable before signing. Have a qualified Thai property lawyer review the agreement. Legal fees for this review typically run THB 15,000 to THB 50,000 - a small cost relative to the risk exposure.

Ignoring the refund mechanism. A contract that says 'full refund in case of developer default' is only as good as the developer's ability to pay. Check the developer's completed project history, publicly available financial statements if they are a listed company on the Stock Exchange of Thailand, and whether other buyers in the project have flagged issues on property forums.

Missing the FET certificate requirement. Foreign buyers of Bangkok condominiums must remit funds from abroad in foreign currency and obtain a Foreign Exchange Transaction (FET) certificate from a Thai bank for the full registered purchase price. If you send baht from a Thai account, you may not qualify for the certificate and may be unable to register ownership. Plan each payment transfer in advance with your bank.

Assuming assignment is always possible. Assignment is a contractual right, not a legal default. If your contract prohibits or restricts it and you need to exit before completion, your options narrow to negotiating a voluntary cancellation with the developer, which typically means losing your deposit payments.

Not budgeting for handover costs. At handover you pay the balance (60% to 75%), transfer fees (currently 2% of the registered value, split by negotiation), sinking fund, and often 1 to 2 months of advance management fees. These add-ons can total 3% to 5% of the purchase price on top of your payment schedule.

FAQ

What is a typical off-plan payment schedule in Bangkok in 2026?

A typical Bangkok off-plan condominium schedule runs across 4 to 6 stages: a reservation deposit of roughly THB 50,000 to THB 200,000, a contract-signing payment bringing the total to 10% of the price, two to four construction milestone payments adding another 10% to 20%, and a final handover payment of 60% to 75%. The exact percentages vary by developer and project tier.

How much of my money is at risk before the building is finished?

In a standard Bangkok mid-market project, you typically have 20% to 30% of the purchase price committed before handover. That is the amount you could lose, in a worst-case default scenario, without recourse beyond civil litigation in Thailand.

Is there any escrow protection for foreign buyers in Thailand?

No. There are no escrow accounts protecting foreign real estate buyers in Thailand in the traditional sense. Your protection comes from three things: contract terms (completion guarantees, delay penalties, refund clauses), the developer's track record and financial health, and a payment schedule that ties each draw-down to a verified construction milestone.

What happens if the developer defaults mid-construction?

You become an unsecured creditor under Thai law. You can file a legal claim, but recovery depends on what assets the developer holds and where you rank among creditors. Recovery is not guaranteed and can take several years. This is why pre-purchase due diligence on the developer matters more than any single contract clause.

Can I sell my off-plan contract before the building is completed?

Yes, in many cases, through a process called assignment. You transfer your contractual right to buy the unit to a new buyer. Many Bangkok developers allow this for a fee of 1% to 3% of the purchase price. Some restrict it. Check your specific contract before assuming assignment is available.

What is a Foreign Exchange Transaction (FET) certificate and why does it matter?

A Foreign Exchange Transaction (FET) certificate - sometimes called a Thor Tor 3 form - is issued by a Thai commercial bank confirming that foreign currency was brought into Thailand and converted to baht. Foreign buyers must obtain one covering the full purchase price to register condominium ownership in their name. You must plan your payment transfers to arrive as foreign-currency remittances, not local baht transfers.

How does the off-plan discount compare to completed resale stock in Bangkok?

As of 2026, market estimates indicate off-plan condominiums in Bangkok are priced roughly 10% to 20% below comparable completed resale units in the same submarket. That discount is the financial return for carrying construction and developer risk over the build period, which typically runs 24 to 48 months.

What should a completion guarantee clause say?

It should state a specific completion date, a grace period (commonly 12 months), and a clear remedy if the deadline plus grace period is missed: either a daily penalty payable to you, the right to cancel with a full refund of all payments, or both. Vague 'best efforts' language is not adequate.

What costs should I budget for at handover beyond my final payment?

At handover, plan for: property transfer fee (currently 2% of the registered value, negotiable as to which party pays), sinking fund (typically THB 400 to THB 700 per square metre), and 1 to 2 months of advance common area management fees (typically THB 40 to THB 80 per square metre per month). These can add 3% to 5% to your total cost.

How do I verify a Bangkok developer is legitimate before paying a reservation deposit?

Check that the developer holds chanote title to the land, has received EIA approval where required, and has registered the project with Thailand's Real Estate Information Center. Review their history of completed projects and, if they are listed on the Stock Exchange of Thailand, their public financial statements. Have a Thai property lawyer review the sale and purchase agreement before you sign or transfer any funds.
