In Q1 2026, our analysts reviewed 23 residential property transactions across Phuket and Koh Samui in which buyers from Central Europe and other international markets incurred measurable financial losses. Below we present five anonymised cases, each dissected in detail. Each illustrates a distinct, preventable type of error.
The average cost of error across our sample was 1.27 million THB (approximately 34,600 USD at the March 2026 rate of 0.0272 USD/THB). In three cases, losses exceeded 2 million THB. The data originates from our internal consultancy case register and public records held at the Phuket Provincial Land Office.
Quick answer
- The single most common error was skipping independent land title verification before paying a deposit - recorded in 9 of 23 cases reviewed
- Overly front-loaded payment schedules (more than 50% of the purchase price paid before foundation completion) appeared in 7 cases
- Rental operator costs are routinely underestimated by 30-45% relative to developer projections
- An illegal nominee shareholder structure instead of a properly secured company or leasehold created exposure equivalent to total loss of the asset
- Buying on the basis of unbuilt infrastructure (planned road, planned marina) reduced actual market value by an average of 18-22% below purchase price
Options and scenarios
Case 1 - skipping land title due diligence (Layan, Phuket)
Starting position: A buyer from Central Europe purchased an off-plan villa in the Layan area for 18.5 million THB. The developer described the title as 'full ownership' and presented a Nor Sor 3 Gor document. The buyer paid a deposit of 1.85 million THB (10%) followed by a first instalment of 3.7 million THB.
The error: No independent title search was commissioned at the Phuket Land Office. Nor Sor 3 Gor is a right of occupancy, not a Chanote (full title). The plot turned out to be partly classified as Forest Land, blocking construction permits for roughly 40% of the planned built area.
Warning signals that were visible in advance:
- No Chanote reference number appeared in any sales materials
- The asking price was 25% below comparable Layan villas with Chanote title (Q4 2025 market range: 23-26 million THB for equivalent floor area, per our data sets)
- The developer declined to share a copy of the title document before accepting the deposit
Financial cost: 5.55 million THB (deposit plus first instalment) is frozen in a legal dispute. Based on our estimates, recovering more than 60% of the paid amount is unlikely given the penalty clauses in the contract.
What we would do differently: Before any payment, we would instruct a lawyer independent of the developer to conduct a full land title search at the Phuket Land Office. The cost of that search is 15,000-25,000 THB. The ratio of verification cost to avoided loss is approximately 1:250.
Case 2 - aggressive payment schedule with an unproven developer (Kamala, Phuket)
Starting position: A buyer purchased a condominium unit in a Kamala project for 6.2 million THB. The payment schedule required: 30% on signing, 30% after three months, 30% after six months, and 10% on key handover. Planned completion: December 2025.
The error: 90% of the purchase price (5.58 million THB) was paid within six months, while construction had reached only 25% completion. The developer halted work in October 2025 citing liquidity problems.
Warning signals:
- A schedule requiring more than 50% payment before the structural shell is complete is a red flag. The Phuket market standard is 30-40% up to structural completion
- The developer had no previously completed projects on the island
- No bank guarantee was offered to protect paid instalments
Financial cost: As of March 2026, the buyer had recovered only 1.2 million THB of the 5.58 million THB paid. Litigation is ongoing. Net loss is estimated at 4.38 million THB (approximately 119,000 USD).
What we would do differently: We would negotiate a payment schedule tied to verified construction milestones, not calendar dates. Maximum payment before a closed structural shell: 40% of the price. We would also verify the developer's history through the Department of Business Development (DBD) and review the company's financial statements for the preceding three years.
Case 3 - buying on promised infrastructure (Maenam, Koh Samui)
Starting position: A buyer acquired a villa in Maenam on Koh Samui for 12 million THB in 2024, motivated by announced plans for a new marina and access road projected to increase property value by 30-40% within two years.
The error: The marina project failed to obtain an Environmental Impact Assessment (EIA) approval. As of March 2026, it remains suspended. The access road was rerouted approximately 1.5 km from its originally announced alignment.
Warning signals:
- The infrastructure project had no approved EIA at the time of purchase
- No Royal Gazette entry confirmed budget allocation for the road
- Maenam recorded short-term rental occupancy of 52% in 2024, below the island average of 61% (STR Global data, 2024)
Financial cost: Current market valuation of the villa is approximately 9.6 million THB, a decline of 20% from the purchase price. The foregone infrastructure premium is estimated at an additional 2-3 million THB.
What we would do differently: We price property solely on the basis of existing, verified infrastructure. Potential public-sector investment is treated as a zero-value option until a valid construction permit has been issued.
Case 4 - underestimating rental operator costs (Surin, Phuket)
Starting position: A buyer purchased a condominium unit in Surin for 8.5 million THB. The developer's projection: rental income of 45,000 THB per month, occupancy of 75%, gross annual yield of 4.8%.
The error: The buyer did not verify the full cost structure of the rental operator before purchase. Actual costs in operation:
- Operator management fee: 25-30% of gross revenue (not 15% as stated in developer materials)
- OTA platform fees (Booking.com, Agoda): 15-18% of online bookings
- Housekeeping and maintenance: 8,000-12,000 THB per month
- Common Area Fee: 3,200 THB per month
- Insurance and minor repairs: 2,000-4,000 THB per month
Warning signals:
- The developer quoted gross yield only, omitting operator, OTA, and maintenance costs
- No independent occupancy analysis was conducted. Our 2025 monitoring data places actual occupancy for condominium units in Surin at 58-65%, not 75%
Financial cost: Actual net yield came in at 2.1% against the projected 4.8%. The annual income shortfall is approximately 229,500 THB (around 6,240 USD per year).
What we would do differently: We build our own financial model using operator costs of 40-45% of gross revenue as the base case. We verify occupancy on OTA platforms for at least five comparable units within 500 metres before committing to any yield projection.
Case 5 - illegal ownership structure (Rawai, Phuket)
Starting position: A buyer acquired a villa in Rawai for 22 million THB through a Thai limited company (Thai Co., Ltd.) in which two Thai nominee shareholders held a combined 51% stake.
The error: The nominee shareholder structure is illegal under the Foreign Business Act (FBA). From 2024 onward, the Department of Special Investigation (DSI) intensified scrutiny of such arrangements across Phuket. The nominee shareholders subsequently filed a claim asserting their rights over the company.
Warning signals:
- Any structure in which a foreigner controls a Thai company whose local shareholders have contributed no genuine capital is at risk of annulment
- DSI announced in 2024 that it was reviewing 2,700 companies in Phuket suspected of nominee arrangements
- Nominee service fees of 50,000-100,000 THB per year create a paper trail that itself documents the fictitious nature of the shareholding
Financial cost: In the worst-case scenario, the buyer loses control of an asset worth 22 million THB (approximately 598,000 USD). As of March 2026, the case is ongoing. Legal costs have already exceeded 800,000 THB.
What we would do differently: We recommend a registered 30-year leasehold with superficies right (right of building) as a security layer, or outright condominium purchase within the legally permitted 49% foreign quota, as the only fully compliant options for foreign nationals in Thailand.

Risks and mistakes
Risk 1 - underweighting title verification. Phuket operates under several land title categories: Chanote, Nor Sor 3 Gor, Nor Sor 3, and Sor Kor 1. Only a Chanote provides full legal protection. A Land Office title search costs a fraction of a percent of any transaction value and should be non-negotiable before a deposit is paid.
Risk 2 - payments disconnected from construction progress. We have monitored the Phuket developer market across multiple cycles. Projects in which more than 60% of the price is payable before structural completion show a statistically higher incidence of delays and work stoppages in our data sets.
Risk 3 - yield projections sourced from developer marketing materials. Based on our estimates, actual net yield for condominium units in Phuket in 2025 ranged from 2.0% to 3.5% annually. Developer brochures in the same period commonly cited 5-8%. The gap is explained almost entirely by omitting operator fees, OTA commissions, maintenance, and vacancy periods.
Risk 4 - nominee shareholder structures. Enforcement of the Foreign Business Act has tightened materially since 2024. DSI investigations are active across Phuket, and court rulings issued in 2025 confirm that shareholdings can be seized and annulled.
Risk 5 - pricing in future public infrastructure. Public infrastructure projects in Thailand take an average of 3-5 years from announcement to completion - and many are delayed further or cancelled. Our analysts value any property solely on its current, verifiable state. Announced projects contribute zero to our base-case valuation until a construction contract is publicly signed.
FAQ
How much does an independent land title search cost in Phuket?
A title verification conducted at the Phuket Land Office by an independent law firm typically costs 15,000 to 40,000 THB (approximately 410-1,090 USD as of 2026), depending on complexity. The process takes 5-15 working days.
What payment schedule is considered safe for off-plan condominium purchases?
We consider a schedule safe when no more than 30-40% of the total price has been paid before the structural shell is closed and certified. The final tranche (20-30%) should be released only upon key handover following a satisfactory inspection.
Is the nominee shareholder structure legal in Thailand in 2026?
No. A nominee structure in which Thai shareholders contribute no genuine capital is illegal under the Foreign Business Act. DSI has been actively investigating and prosecuting such arrangements in Phuket since 2024, and enforcement shows no sign of easing.
What is the realistic net rental yield for a condo in Phuket?
Based on our 2025 monitoring data, net yield after operator fees, OTA commissions, maintenance costs, and vacancy runs at 2.0-3.5% per year. Premium locations such as Bang Tao and Surin can approach the upper end of that range under favourable occupancy conditions.
How do we verify a developer's track record in Phuket?
Our analysts check the company history on the Department of Business Development (DBD) platform, review three years of financial statements, inspect previously completed projects on the ground, and confirm that a valid Construction Permit is held at the relevant local authority office.
Is a leasehold a safe alternative to a nominee company structure?
A 30-year leasehold registered at the Land Office and secured with a superficies right (right of building) is one of two fully legal forms of property control available to foreign nationals in Thailand. It does not replicate freehold ownership, but it provides enforceable, registered rights with a clear legal basis.
What should we require before buying property near planned infrastructure?
Our minimum threshold is three documents: an approved EIA, a Royal Gazette entry confirming budget allocation, and a signed construction contract with the implementing contractor. Without all three, our analysts assign zero value to the infrastructure upside in any valuation model.
Which operator costs do developers typically omit from yield projections?
The most commonly omitted items are: the operator management fee (25-30% of gross revenue), OTA platform commissions (15-18% per online booking), housekeeping and maintenance (8,000-12,000 THB per month), Common Area Fee, and insurance. Combining these can reduce gross yield by half or more.
Are Nor Sor 3 Gor titles acceptable for villa purchases in Phuket?
Nor Sor 3 Gor confers rights of occupancy and can be converted to Chanote, but the conversion process is not guaranteed and can take years. We advise buyers to treat anything below Chanote as a material risk factor that should be reflected in price negotiation and legal protections, not accepted at face value.
What is the typical cost of a legal ownership-structure review before buying a villa?
A full legal review covering title, corporate structure, and purchase contract typically costs 80,000-150,000 THB for a villa transaction in Phuket. Set against the exposure visible in Case 5 (up to 22 million THB at risk), the cost-to-protection ratio is compelling.
