Based on our Q1 2026 estimates, the average price discount for off-plan property in Phuket sits between 15% and 25% relative to comparable ready units in the same district. We are currently monitoring over 40 active construction projects across Bang Tao, Layan, Kamala, and Rawai. Below, we break down how these transactions actually work - mechanically and contractually - and where the meaningful risks sit.
Two elements matter most to any internationally minded buyer: the way payments are staged over time, and the absence of systemic capital protection instruments familiar from European markets. There are no escrow accounts for foreign real estate buyers in Thailand. Capital protection depends entirely on contract wording and the track record of the developer.
Quick answer
- Typical Phuket off-plan payment schedules run 5 to 7 tranches spread across 18 to 30 months of construction
- Reservation fees generally range from 50,000 to 200,000 THB; the sale and purchase agreement (SPA) typically requires approximately 30% of the purchase price
- The off-plan discount in Bang Tao and Layan is approximately 15 to 25% versus the secondary market, per our Q1 2026 data
- All payments flow directly to the developer or its project company - there is no third-party holding mechanism
- Liquidated damages clauses in standard contracts typically specify 0.01 to 0.1% of contract value per day of delay, though we also encounter contracts with no such clause at all
- On Koh Samui (Bophut, Maenam), off-plan supply is thinner but entry prices are roughly 20 to 35% lower than Phuket for comparable build quality
Options and scenarios
How payment models are structured in practice
Drawing on contracts our team has reviewed across 2024 and 2026, we identify three recurring payment structures in Phuket condominium and villa projects.
Model A - Progressive (most common in condominium projects, Bang Tao, Kamala)
This is the structure we encounter most frequently in mid-to-large condominium developments:
- Reservation: 1 to 2% of price (often a fixed 50,000 to 100,000 THB, non-refundable)
- SPA signing within 30 days of reservation: top-up to 30% of total price
- Foundation completion: 10%
- Superstructure (structural frame complete): 20%
- Interior fit-out complete: 10%
- Transfer and handover: 30%
Under this model, approximately 40% of the buyer's capital is committed before foundations are poured. That is a meaningful exposure, because at that stage the developer may still be finalising construction permits and, for larger projects, awaiting Environmental Impact Assessment (EIA) approval.
Model B - Front-loaded (villa projects, Layan, Surin)
Some villa developers require 50% of the price before structural work begins, with the remainder split across two or three later tranches. This concentrates risk in the earliest phase, when the asset has the least physical substance.
Model C - Back-loaded (less common, established developers)
Reservation and SPA combined account for only 20%; construction milestones add another 30%; handover triggers the final 50%. This is the most buyer-friendly structure and, in our data sets, it appears primarily with developers who can demonstrate a documented portfolio of completed projects.
Pricing mechanics: off-plan versus secondary market
To illustrate the discount with concrete numbers from our monitoring (orientational figures, Q1 2026, Bang Tao):
- Off-plan condominium, 45 sq m, premium specification: approximately 4,500,000 THB (roughly 100,000 THB per sq m)
- Comparable ready unit, 2 to 3 years old: approximately 5,600,000 THB (roughly 124,000 THB per sq m)
- Implied discount: approximately 20% on a per-square-metre basis
At our March 2026 reference rate of approximately 1 THB = 0.028 USD (and for readers tracking in other currencies, we note 1 THB traded near 0.11 PLN in the same period), the off-plan unit comes in around 126,000 USD versus the ready unit at approximately 157,000 USD. The gap is real - but the buyer carries the risk of delays, specification changes, and capital being tied up for 18 to 30 months.
On Koh Samui, a comparable analysis for Bophut shows off-plan discounts in the 18 to 22% range relative to ready villas, with a two-bedroom villa off-plan starting from approximately 6,000,000 THB per our current monitoring.

Risks and mistakes
EIA and permitting delays
Thailand's Environmental Impact Assessment process is mandatory for projects exceeding 80 units or located in protected zones. We monitor cases where developers launched off-plan sales before receiving a positive EIA decision. An EIA delay can halt construction for 6 to 12 months. Based on our estimates, approximately 15% of projects on Phuket's west coast experienced such delays between 2023 and 2025.
The contract clause to verify: does the buyer have the right to withdraw with a full refund if the developer fails to obtain a construction permit within a specified period (for example, six months from SPA signing)?
Structural phase: the highest-frequency delay point
The superstructure phase is where schedule slippage is most common. Subcontractor issues, material supply gaps, and the monsoon season (May through October) routinely push timelines out by 3 to 6 months. Our team verifies construction progress on the ground for projects we cover.
The clause to check: liquidated damages. The market standard is 0.01 to 0.05% of contract value per day of delay. By our calculations, on a 5,000,000 THB condominium at 0.05% per day, the daily penalty is approximately 2,500 THB. At six months of delay that totals roughly 450,000 THB - around 3% of contract value. This is a modest deterrent for a developer.
Fit-out and handover: specification drift
Material specification substitution is a recurring issue. We check whether contracts name specific brands and technical parameters for finishes. Contracts that leave specifications vague give developers room to substitute cheaper alternatives without formal breach.
The handover inspection (snagging) is the moment buyers can formally log defects. We see two approaches: a single-sign-off inspection (buyer signs the handover protocol and loses further recourse) and a warranted handover (typically 12 months on structural elements, 6 months on mechanical and electrical installations).
No systemic payment protection
To restate this clearly: there are no escrow accounts for foreign real estate buyers in Thailand. Funds go directly to the developer's project company account. The practical safeguards available to a buyer are:
- Contract clauses requiring refund of all payments if specified milestones are missed
- Developer track record - a documented portfolio of completed, delivered projects
- Independent legal due diligence before signing (cost: approximately 30,000 to 60,000 THB, but it removes critical contractual risks)
- Verification of land title documents (Chanote is the strongest title; Nor Sor 3 Gor carries more risk)
Common structural mistakes by buyers
- Signing the SPA without independent legal review
- Paying reservation funds to an agent's personal account rather than the project company account
- Not confirming the developer holds a valid Construction Permit before paying beyond the reservation fee
- Overlooking the assignment (resale) clause - whether the contract allows pre-completion transfer and at what fee
- Ignoring transfer costs: the land registration fee (2% of the assessed value) and the withholding tax payable by the seller, which can affect net proceeds at resale
FAQ
What is the typical reservation fee for off-plan property in Phuket in 2026?
We most commonly see reservation fees between 50,000 and 200,000 THB. The fee is typically non-refundable and credited against the first instalment. Some developers in Layan and Bang Tao apply higher reservation amounts of around 300,000 THB.
Are off-plan payments in Thailand protected by any third-party holding arrangement?
No. There are no escrow accounts for foreign real estate buyers in Thailand. Payments go directly to the developer. Protection depends entirely on contract terms and pre-signing due diligence.
What penalty does a developer face for construction delays in Phuket?
The market standard is a liquidated damages clause of 0.01 to 0.1% of contract value per day of delay. We also encounter contracts with no such clause, which our analysts treat as a red flag.
Can I resell an off-plan unit before construction is complete?
Yes, if the contract includes an assignment clause. Based on our monitoring, approximately 60 to 70% of Phuket developers permit assignment, though an assignment fee of 1 to 3% of contract value is common.
What off-plan discount can I realistically expect in Phuket versus a ready unit?
In Bang Tao and Layan, our Q1 2026 data points to discounts of 15 to 25% relative to comparable secondary-market units. In Bophut and Maenam on Koh Samui, the range is approximately 18 to 22%.
How long does a typical off-plan project in Phuket take to complete?
Condominiums: 18 to 30 months from construction start. Villas: 12 to 18 months. Based on our estimates, delays of 3 to 6 months affect approximately 30 to 40% of projects.
What developer documents should be verified before paying beyond the reservation?
The critical documents are: Construction Permit, land title deed (Chanote preferred), EIA approval where required, company registration with the Ministry of Commerce, and the developer's financial statements for the project company.
How does tax work when selling Phuket property purchased off-plan?
On the Thai side, the seller pays a withholding tax calculated on a progressive scale depending on the holding period. Buyers from countries with a double taxation agreement with Thailand should also verify their domestic reporting obligations with a qualified tax adviser in their country of residence.
Which payment model carries the least risk for the buyer?
Based on our analysis, Model C (back-loaded) minimises early-stage exposure because the largest tranche falls at handover, when the asset is physically complete and defects can be inspected. The trade-off is that this model is typically offered only by developers with an established delivery record.
What should I check before paying a reservation fee?
Confirm that the reservation agreement specifies the refund conditions, that the receiving account belongs to the registered project company (not an individual), and that the developer can present at minimum the land title deed for the project site. Construction Permit availability at this stage varies but should be on the due diligence checklist before SPA signing.
