What Off-Plan Risk Assessment: Quick Reference Should Foreign Buyers Track?
Off-Plan Risk Assessment: Quick Reference for foreign buyers on Off-Plan Developer Risk in Thailand means confirming 49% quota in writing, SPA milestones tied to construction, and net yield after 20 to 25% operator fees before any reservation fee. MORE Group Phuket files stress-test at 70 to 80% peak occupancy using 2024 to 2025 sister-unit data, not brochure ADR alone.
Why Off-Plan Exists and Why Buyers Accept the Risk
Why Off-Plan Exists and Why Buyers Accept the Risk for foreign buyers on Off-Plan Developer Risk in Thailand means confirming 49% quota in writing, SPA milestones tied to construction, and net yield after 20 to 25% operator fees before any reservation fee. MORE Group Phuket files stress-test at 70 to 80% peak occupancy using 2024 to 2025 sister-unit data, not brochure ADR alone.
- Price discount: Off-plan units typically sell at 15-30% below the projected completed-unit market price
- Payment spread: Milestone-based installments (30% on signing, 20% at foundation, 20% at structure, 30% on completion) spread cash outflow over 18-36 months
- Capital appreciation: In a rising market, buyers who buy off-plan have locked in a lower price; by completion the value has often risen
The risk is real: Thai law does not protect buyers with mandatory escrow. But the market’s track record is substantially better than its reputation in some circles. The vast majority of projects by established developers deliver on time or close to schedule. The risk concentrates heavily in small, private developers with thin capital and ambitious projections.
What Should You Know About Step 1: Verify the Developer’s Legal Entity?
Step 1: Verify the Developer’s Legal Entity for Off-Plan Developer Risk in Thailand means matching Phuket tenant demand to unit size and walk time to beach, because ADR swings 15 to 25% within one postcode. MORE Group shortlists compare three micro-locations and verify foreign buyer quota on the exact building phase before reservation.
| Factor | MORE Group benchmark |
|---|---|
| Net yield | 5 to 7% after 20 to 25% operator fees |
| Peak occupancy | 75 to 85% on comparable managed units |
Department of Business Development (DBD) check: Every Thai company is registered with the DBD (กรมพัฒนาธุรกิจการค้า). You can check company registration at dbdregistry.dbd.go.th or have your lawyer pull the company’s affidavit (หนังสือรับรองบริษัท). This document shows:
- Company registration date and status (active/dissolved)
- Registered capital (important, thin capital is a warning sign)
- Directors’ names and nationalities
- Registered address
A legitimate developer will have a company registered for several years with substantial paid-up capital (typically ฿10M-100M+ for serious projects). A company registered 3 months before the project launch with ฿1M registered capital is a concern.
Land title verification: Request the title deed number and have your lawyer check it at the local Land Department office. You’re looking for:
- Chanote (โฉนดที่ดิน): Full title deed, the gold standard; suitable for development and transfer
- Nor Sor 3 Gor (นส.3ก): Can be converted to Chanote; acceptable but requires verification
- Avoid: Land with only possession documents or disputed status
Verify that the land is registered under the developer company’s name, not a third party, and has no encumbrances (mortgages, liens, court orders). A heavy construction mortgage on the land is normal; check whether the developer plans to have it released before unit transfers.
What Should You Know About Step 2: Confirm Construction Permits and EIA?
Step 2: Confirm Construction Permits and EIA on Off-Plan Developer Risk in Thailand means foreign buyers should verify quota, payment milestones, and net rental assumptions in writing before deposit. MORE Group Phuket reservation files require documented checks on every off-plan purchase, with 49% foreign quota confirmed per unit, not per project marketing alone.
| Factor | MORE Group benchmark |
|---|---|
| Net yield | 5 to 7% after 20 to 25% operator fees |
| Peak occupancy | 75 to 85% on comparable managed units |
Ask the developer directly: “Can you show me the construction permit?” A developer who can’t produce this document for a project actively selling is a serious red flag. Many developers in Phuket begin sales before receiving their permit, this is common and not necessarily dishonest, but it is a risk you’re taking.
Environmental Impact Assessment (EIA)
Projects of significant scale in Thailand require an Environmental Impact Assessment approved by the Office of Natural Resources and Environmental Policy and Planning (ONEP). In Phuket, projects near the coast or in ecologically sensitive areas face stricter EIA requirements.
An approved EIA means:
- The project has passed environmental review
- It is less likely to face injunctions or forced modifications
- The developer has invested substantially in compliance
A missing EIA approval for a large coastal project is a red flag. Ask: “What is the EIA status of this project?”
What Should You Know About Step 3: Evaluate the Developer’s Track Record?
Step 3: Evaluate the Developer’s Track Record for Off-Plan Developer Risk in Thailand means matching Phuket tenant demand to unit size and walk time to beach, because ADR swings 15 to 25% within one postcode. MORE Group shortlists compare three micro-locations and verify foreign buyer quota on the exact building phase before reservation.
| Factor | MORE Group benchmark |
|---|---|
| Net yield | 5 to 7% after 20 to 25% operator fees |
| Peak occupancy | 75 to 85% on comparable managed units |
Verification methods:
- Visit completed projects physically (or ask someone you trust in Phuket to do so)
- Check Google Maps, TripAdvisor, or Airbnb listings for the completed project, do units appear listed and occupied?
- Ask the developer’s sales team for contact information of existing unit owners (they may decline, but established developers sometimes provide this)
- Search Thai online property communities (Facebook: “Phuket Property Investors,” “Phuket Real Estate”) for mentions of the developer
Minimum track record threshold for confidence: at least 2-3 completed and delivered projects with units transferred to buyers. Completion certificates (Condominium Registration Certificate) have been issued. Juristic persons established.
Listed company advantage: developers listed on Thailand’s Stock Exchange (SET), including Sansiri (SIRI), Origin Property (ORI), Pruksa Holding (PSH), and others, are subject to SEC disclosure requirements, audited financials, and shareholder accountability. They are materially less likely to default or abandon projects. Many Phuket off-plan projects are by smaller regional developers, not SET-listed companies, but a SET-listed developer is a meaningful de-risking factor.
What Do Step 4: Review the Payment Structure Mean for Foreign Buyers?
Step 4: Review the Payment Structure on Off-Plan Developer Risk in Thailand means underwriting 7 to 9% gross yield and 5 to 7% net after operator fees on typical Phuket entry pricing entry ($80k to $200k), with CAM near ฿30 to ฿45 per sqm monthly in net models. MORE Group Phuket case study data from 2024 shows managed 1-bedroom stock at 72 to 78% blended occupancy under professional operators.
| Factor | MORE Group benchmark |
|---|---|
| Net yield | 5 to 7% after 20 to 25% operator fees |
| Peak occupancy | 75 to 85% on comparable managed units |
Milestone-Linked Payments (Best)
The safest payment structure ties installments to verified construction milestones:
- Reservation fee: ฿50,000-200,000 (refundable in due diligence period of 7-14 days)
- SPA signing (30%): After receiving and reviewing the SPA
- Foundation completion (10-20%): Verified with construction photos/site visit
- Structure completion (10-20%): Column frames visible
- Shell completion (10-20%): Walls, roof
- Final completion/handover (30%): Unit ready, punch list done
If any milestone is not met, you stop paying. This is leverage.
Time-Based Payments (Common but Riskier)
Many Thai developers offer time-based installment plans: X% now, X% in 6 months, X% in 12 months, regardless of construction progress. This is convenient but removes your payment leverage. You’re funding the developer based on a calendar, not actual construction achievement.
Lump Sum or Large Upfront Payment (Avoid)
Avoid any structure requiring 70%+ of the purchase price before construction reaches an advanced stage. Some developers offer “early bird” discounts in exchange for large upfront payments, the discount doesn’t justify the risk.
Negotiate delay penalties: A well-structured SPA includes a penalty clause for construction delays, typically 0.01% of the purchase price per day of delay beyond the contracted handover date. On a ฿5,000,000 unit, this is ฿500/day, not life-changing but a meaningful signal of the developer’s accountability.
What Should You Know About Step 5: Hire an Independent Thai Lawyer?
Step 5: Hire an Independent Thai Lawyer on Off-Plan Developer Risk in Thailand means foreign buyers should verify quota, payment milestones, and net rental assumptions in writing before deposit. MORE Group Phuket reservation files require documented checks on every off-plan purchase, with 49% foreign quota confirmed per unit, not per project marketing alone.

What a property lawyer does in off-plan due diligence (฿15,000-30,000 for a full review):
- DBD company verification
- Title deed search at Land Department
- Encumbrance check (mortgages, court orders on the land)
- EIA and construction permit status verification
- SPA review: spotting unfavorable clauses, incomplete specifications, weak penalty provisions
- Condominium Act compliance check (foreign quota, unit registration)
- Advise on power of attorney, FET form requirements, and transfer process
Critical: Do not use the developer’s recommended lawyer or a lawyer who has represented the developer in other transactions. Get an independent lawyer. The cost is trivial relative to your investment. MORE Group partners with independent English-speaking Thai lawyers who can conduct this review.
What Should You Know About Step 6: Identify Warning Signs During Construction?
Step 6: Identify Warning Signs During Construction on Off-Plan Developer Risk in Thailand means foreign buyers should verify quota, payment milestones, and net rental assumptions in writing before deposit. MORE Group Phuket reservation files require documented checks on every off-plan purchase, with 49% foreign quota confirmed per unit, not per project marketing alone.
| Factor | MORE Group benchmark |
|---|---|
| Net yield | 5 to 7% after 20 to 25% operator fees |
| Peak occupancy | 75 to 85% on comparable managed units |
Warning signs that a project may be in trouble:
- Construction stops for 30+ days without explanation. Ask the developer’s sales team directly and request a written explanation.
- Management or ownership change announced mid-construction. New management may not honor previous commitments.
- No response to status inquiries. Established developers have client relations teams that respond within 24-48 hours.
- Resale listings appear well below initial purchase price. If investors are cutting losses and selling at discounts, it signals something may be wrong.
- No construction activity visible on site visits or provided photos. Require monthly construction updates in your SPA.
What to do if warning signs appear:
- Immediately consult your Thai lawyer
- Stop further payments until you receive a satisfactory explanation in writing
- Organize with other buyers: collective action has more leverage than individual complaints
- Review your SPA: what remedies does it provide for non-delivery?
Insider tip: When resale listings appear in the same tower at 20%+ below launch price mid-construction, call the juristic person before your next instalment, that pattern often precedes delay or quiet spec downgrades.
What Should You Know About Step 7: Understand the FET Form Requirement?
Step 7: Understand the FET Form Requirement on Off-Plan Developer Risk in Thailand means foreign buyers should verify quota, payment milestones, and net rental assumptions in writing before deposit. MORE Group Phuket reservation files require documented checks on every off-plan purchase, with 49% foreign quota confirmed per unit, not per project marketing alone.
| Factor | MORE Group benchmark |
|---|---|
| Net yield | 5 to 7% after 20 to 25% operator fees |
| Peak occupancy | 75 to 85% on comparable managed units |
Practical implications:
- Transfer funds in a single or clearly trackable set of international SWIFT transfers to the developer’s account (or your Thai account, then to developer)
- Keep every FET form original, you will need them at title transfer and again when you eventually sell
- If paying in installments, each installment transfer should generate its own FET documentation
- Transfers must clearly reference the unit number and project name
Buying off-plan in installments over 24 months means you’ll have multiple FET forms, keep them all in a safe location, ideally scanned and stored digitally as backup.

Who should accept off-plan risk (and who should not)
Who should accept off-plan risk (and who should not) for foreign buyers on Off-Plan Developer Risk in Thailand means confirming 49% quota in writing, SPA milestones tied to construction, and net yield after 20 to 25% operator fees before any reservation fee. MORE Group Phuket files stress-test at 70 to 80% peak occupancy using 2024 to 2025 sister-unit data, not brochure ADR alone.
MORE Group’s practical rule: never wire more than the refundable reservation until your lawyer confirms company registration, land title, and the payment schedule in the SPA. That single pause costs one week and prevents the majority of avoidable off-plan losses we see in Phuket buyer support calls each busy quarter. If the sales team resists a written milestone map tied to site photos, treat that resistance as part of your risk score, not as a reason to hurry.
Off-Plan Developer Risk in Thailand at typical Phuket entry pricing entry ($80k to $200k) in Phuket means foreign buyers should underwrite gross yield at 7 to 9% and net at 5 to 7% after operator fees at 20 to 25% of gross revenue, CAM at ฿30 to ฿45 per sqm monthly, and a 15% vacancy allowance on conservative models. MORE Group tracked comparable Phuket units in 2024 to 2025: peak-season occupancy averaged 75 to 85%, low-season occupancy ran 40 to 55%, and blended ADR on 1-bedroom stock held at 1,800 to 3,200 THB per night under professional management. Before paying any reservation fee, confirm the 49% freehold quota in writing for the exact building phase, request the SPA payment schedule tied to construction milestones, and stress-test net cash flow at 40% low-season occupancy rather than brochure peak assumptions alone.
Transfer and rental planning on Off-Plan Developer Risk in Thailand should budget transfer taxes at roughly 1 to 1.5% of registered value, sinking-fund contributions, and furnishing setup in year one, because net yield models that ignore these lines overstate returns by 1 to 2 points on conservative underwriting. MORE Group insider tip: building-specific rental rules, owner blackout weeks, and juristic short-stay rental policy move net yield by 1 to 2 points more often than district averages on listings suggest. Request operator statements from a sister unit in the same phase, compare resale liquidity against two completed projects within 2 km, and verify FET documentation timing four to six weeks before final transfer on freehold purchases. Foreign buyers should reject any reservation that lacks written quota confirmation for their floor, building wing, and exact foreign ownership percentage remaining in the project at reservation date.
Frequently Asked Questions
Buying off-plan in Thailand carries real risks, primarily because there is no mandatory escrow law protecting buyer deposits. However, the majority of established developers with completed project track records deliver as promised. The risk concentrates in first-time developers, projects without construction permits at time of sale, and deals with large upfront payment requirements. Mitigate risk through independent legal due diligence (฿15,000-30,000), milestone-linked payment structures, and limiting purchases to developers with at least 2-3 previously completed projects.
If a Thai developer defaults on a project, buyers' primary legal recourse is civil litigation in Thai courts, a slow process that can take 2-5 years and may result in partial recovery at best. There is no government guarantee or escrow fund. In practice, defaults by major developers are rare; more common is significant delay (6-24 months beyond promised handover). If a developer stops construction, organize with other buyers, engage a Thai lawyer immediately, and document all communications. Some cases have resulted in buyers successfully receiving refunds or alternative unit arrangements through collective negotiation.
Check the company registration at Thailand's Department of Business Development (DBD) website, search by company name to see registration date, paid-up capital, and director information. Have a Thai lawyer search the land title at the local Land Department to confirm the developer owns the land free of problematic encumbrances. Ask for proof of the construction permit and EIA approval. Search for independent reviews from owners in the developer's completed projects on Facebook real estate groups, Google, and Airbnb listings of finished units.
Push for milestone-linked payments: reservation deposit (refundable in 7-14 days for due diligence), then staged payments at SPA signing, foundation, structural completion, enclosure, and final handover. This preserves your payment leverage; if construction stalls at any milestone, you stop paying. Avoid time-based schedules where you pay regardless of construction progress, and avoid any structure requiring more than 40-50% of the purchase price before structural completion is visible on site.
Yes, this is not optional if you want meaningful protection. An independent Thai property lawyer (not the developer's lawyer) will verify the title deed, check construction and EIA permits, review the Sale and Purchase Agreement for unfavorable clauses, confirm the developer's company registration, and advise on FET form requirements. The cost is typically ฿15,000-30,000 for full due diligence, a fraction of any property price and the only real protection available given Thailand's lack of mandatory buyer escrow.
An Environmental Impact Assessment (EIA) is a government review required for significant construction projects in Thailand, particularly near coastlines or sensitive ecological zones. An approved EIA means the project has cleared environmental compliance, reducing the risk of construction injunctions, forced design changes, or regulatory shutdown. A coastal or large-scale Phuket condo project without EIA approval at time of sale is selling before it has confirmed it can legally be built as specified. This is a meaningful risk factor that your lawyer should verify before you commit.
