Off-Plan vs Resale Property Price Difference in Thailand 2026
By THAI.ESTATE Editorial Team12 min read
Buying off-plan in Thailand typically costs 10% to 30% less per square metre than buying a completed resale unit in the same building or the same submarket, as of 2026. That discount is real - but it comes attached to risks that completed-unit buyers do not carry. This guide breaks down the math, explains where the savings come from, and shows you exactly what you give up in exchange for a lower entry price.
The price gap exists because developers need early buyers to fund construction. You are, in effect, financing part of the build. The developer prices that favour into your contract. Resale sellers price at or above market because the product already exists, the title is clear, and you can move in immediately. Understanding this exchange is the starting point for any honest comparison.
Quick answer
- Off-plan discount vs. resale in the same project or submarket: 10% to 30% (indicative, as of 2026; varies by location, developer tier and construction stage)
- In Phuket, per market estimates for 2026, off-plan condominiums in Rawai and Chalong launch at roughly THB 80,000 to 110,000 per sq m, while completed resale units in the same districts trade at THB 95,000 to 140,000 per sq m
- In Bangkok (Sukhumvit corridor), off-plan launches from established developers sit around THB 130,000 to 200,000 per sq m; comparable resale stock in the same area is THB 160,000 to 240,000 per sq m (market estimates, Q1 2026)
- The discount narrows the closer a project is to completion; buying at groundbreaking captures the widest gap
- You carry capital at risk for the entire construction period: in Thailand there is no mandatory escrow for foreign buyers, so your staged payments sit with the developer
- Completion risk, construction delays, and the absence of a physical asset during the build period are the costs you pay for the lower price
- Resale buyers pay a higher entry price but face zero completion risk and can rent or use the unit from day one
Options and scenarios
Scenario 1: Buying off-plan at launch, Phuket condo, 2026
You reserve a 50 sq m unit in a new project in Bang Tao at THB 90,000 per sq m, total price THB 4,500,000. The payment schedule looks like this:
- Reservation deposit: THB 50,000 to 100,000 (non-refundable in most contracts, paid to secure the unit and lock the price)
- Contract signing (within 14 to 30 days of reservation): 10% to 20% of the purchase price, so THB 450,000 to 900,000
- Construction milestones (foundation, structure, roofing, interiors): typically 4 to 6 payments, each 10% to 15%, paid over 18 to 36 months
- Handover: final payment, commonly 20% to 30%, paid when you receive the keys and the unit passes inspection
At groundbreaking, a comparable completed resale unit in the same submarket lists at THB 5,400,000 (THB 108,000 per sq m, indicative). Your discount is THB 900,000 (20%). If the project completes on time in 24 months and the market holds, that gap can represent genuine capital gain. If the project delays by 12 months, your money earns nothing during that extra year and the resale market may have moved.
Scenario 2: Buying off-plan at mid-construction, Bangkok, 2026
A project is 60% built. The developer still sells remaining units at THB 155,000 per sq m (50 sq m = THB 7,750,000). Resale in the same building (early buyers who want to exit) is priced at THB 170,000 per sq m (THB 8,500,000). Your discount is THB 750,000 (8.8%). Construction risk is lower because structural work is visible, but you still carry the final 40% of the build.
Your remaining payment schedule compresses: perhaps 2 milestone payments and a handover payment over 10 to 14 months. Capital at risk is lower in absolute terms and in time. The assignment market (buying a contract from an early buyer before title transfer) creates this opportunity, and it is legitimate under Thai law if the developer consents and the original contract allows it.
Scenario 3: Buying resale (completed unit), Phuket, 2026
You buy a 50 sq m completed condo in Bang Tao at THB 5,200,000 (THB 104,000 per sq m). You pay the full price at transfer, receive the chanote (the full title deed, the highest form of land title in Thailand) immediately, and can rent the unit from month one. You pay a transfer fee (typically 2% of the assessed value, shared by negotiation), specific business tax or stamp duty depending on how long the seller has owned the unit, and withholding tax settled by the seller. There is no construction wait and no milestone payment schedule.
The higher entry price is the only real cost you absorb compared to the off-plan buyer. If your plan is rental income or personal use from year one, resale is straightforward.
Scenario 4: Off-plan with rental guarantee promise
Some developers offer a rental guarantee, typically 5% to 7% per year for 2 to 3 years, as a marketing tool. This is not a government-backed instrument. It is a contractual promise by the developer. If the developer faces cash flow problems, that guarantee can go unpaid. Add the guarantee yield to your off-plan discount calculation, but model the downside: if the guarantee fails, your actual yield in year one may be 1% to 3% (the realistic market rental yield for many Thai resort condos), while your capital is still locked in an incomplete building.

Risks and mistakes
Mistake 1: Treating the discount as guaranteed profit
The off-plan discount is a present price against a future market. If the resale market in that submarket drops between your reservation date and handover, your 20% 'discount' can shrink or disappear. Market estimates for some Phuket resort segments show price corrections of 5% to 10% in oversupplied zones between 2022 and 2024. Always model the scenario where resale prices are flat or lower at handover.
Mistake 2: Ignoring the payment schedule shape
A schedule that front-loads payments (for example, 50% due within the first 6 months) means your capital is at risk for the longest possible period with the least construction completed. A back-loaded schedule (most money due at handover) keeps your funds out of the developer's hands until the building is real. Always read the milestone schedule clause by clause and calculate your cumulative payment at each stage.
Mistake 3: No completion guarantee clause
If the developer defaults mid-build in Thailand, you are an unsecured creditor. There is no mandatory state-backed buyer protection fund for real estate purchasers. Your only recourse is the contract. A strong contract should include:
- A long-stop completion date (a final backstop deadline, not just an estimated handover date)
- Delay penalties paid to you, typically 0.01% to 0.03% of the purchase price per day of delay beyond the agreed date
- A refund clause that specifies the conditions under which you can exit and what you receive back (full principal, or principal minus specified deductions)
- Assignment rights so you can sell the contract to another buyer if you need to exit before completion
Without these clauses in writing, your position in a default scenario is weak.
Mistake 4: Assuming the foreign quota is safe
Under the Condominium Act, foreigners may own up to 49% of the total floor area of a condominium building. At reservation, the developer may tell you the quota is available. By the time the building completes 2 to 3 years later, that quota may be exhausted by other buyers. If foreign quota is unavailable at transfer, you cannot take ownership on a foreign freehold basis. Always get a written confirmation of your specific unit's quota allocation in the sale and purchase agreement.
Mistake 5: Relying on a rental guarantee without reading the contract
Rental guarantees are developer obligations, not insurance products. The fine print often includes conditions: the unit must be placed in the developer's rental pool, your personal use may be restricted to 30 days per year, and the guarantee payment mechanism may be offset against sinking fund or management fees. Read every sub-clause before factoring the guarantee into your purchase decision.
Mistake 6: No legal review of the sale and purchase agreement
The standard developer contract in Thailand is drafted to protect the developer. Key terms - refund conditions, delay penalties, assignment rights, what constitutes a default, dispute resolution - are all negotiable before signing. A Thai property lawyer (not the developer's in-house legal team) should review the contract before you pay anything beyond the reservation deposit.
Mistake 7: Confusing developer reputation with legal protection
A developer may have a strong reputation and a portfolio of completed projects. That does not replace contractual protection. Developer financial health can change between launch and completion. The contract is your legal tool; reputation is a screening filter, not a guarantee.
FAQ
How much cheaper is off-plan vs. resale in Thailand in 2026?
As of 2026, the typical off-plan discount against comparable completed resale stock in the same submarket is 10% to 30%, depending on the project, the developer tier, and the stage of construction at which you buy. Buying at groundbreaking captures the widest discount. Buying at 60% completion may yield only 5% to 10% less than resale.
Is the off-plan price difference worth the risk in Thailand?
That depends on your holding period, your financial resilience if the project delays, and the quality of your contract protections. If you have a back-loaded payment schedule, strong delay penalty and refund clauses, and a developer with a verified completion track record, the discount can represent genuine value. If the contract lacks these protections, the discount may not compensate for the risk.
What payment schedule should I expect for off-plan in Thailand?
A typical schedule: reservation (THB 50,000 to 200,000), 10% to 20% at contract signing, four to six milestone payments of 10% to 15% each during construction, and 20% to 30% at handover. The exact structure varies by developer and project. A buyer-friendly schedule is back-loaded: more money at handover, less during early construction.
Can I sell an off-plan contract before the building is finished?
Yes, this is called assignment of contract (or 'flipping' in informal usage). You transfer your rights under the sale and purchase agreement to a new buyer before the title deed is issued. Most developer contracts require the developer's written consent for assignment, and some charge an assignment fee (commonly 1% to 3% of the purchase price). Check the assignment clause before you buy if reselling before completion is part of your plan.
Are there escrow accounts protecting my payments in Thailand?
No. There is no mandatory escrow system for foreign real estate buyers in Thailand. Your staged payments go directly to the developer. This is why the payment schedule structure, the developer's track record, and your contract protections (refund clauses, delay penalties, long-stop dates) are the primary safety mechanisms - not a third-party fund.
What happens if the developer goes bankrupt before the building is finished?
You become an unsecured creditor. Recovery depends on the developer's remaining assets, the status of any bank loans secured against the land, and the terms of your contract. In practice, partial recovery in Thai developer insolvencies can take years and often returns less than the full principal. This is the core risk of off-plan buying in any market, and Thailand is no exception. Screening developer financial health before signing is critical.
How do I confirm foreign ownership quota before buying off-plan?
Ask the developer for a written statement of the foreign quota remaining in the specific building at the time of contract signing. Have your lawyer verify this with the land department records where possible. Request a clause in the sale and purchase agreement that guarantees your unit is allocated within the foreign quota, and specifies a refund if that allocation cannot be honoured at transfer.
Does the off-plan discount still apply if I buy from an early buyer (assignment)?
Partially. An early buyer who purchased at launch and is now reselling their contract mid-construction will typically price the assignment above their original purchase price, capturing some of the discount for themselves. You may still save 5% to 10% versus direct resale, but the full launch discount is gone. The benefit you gain is reduced construction risk (the building is partly complete) rather than maximum price saving.
What is a sinking fund and do I pay it on off-plan properties?
A sinking fund is a one-time payment collected at handover (sometimes at contract signing) to fund major future repairs to the building's common areas - lifts, roof, pool infrastructure. It is typically THB 300 to 700 per sq m as of 2026 (indicative). It is separate from the monthly common area management fee. For a 50 sq m unit, expect THB 15,000 to 35,000. This is a standard charge for both off-plan and resale purchases and is not negotiable in most projects.
Is resale always safer than off-plan in Thailand?
Resale carries zero completion risk, which is a significant safety advantage. However, resale buyers face their own due diligence requirements: verifying the chanote (full title deed) is clean and free of encumbrances, checking outstanding common area fees owed by the seller, confirming the foreign quota is available if relevant, and assessing building condition. Neither route is risk-free; the nature of the risk differs.
