The off-plan vs resale choice is one of the largest decisions a foreign buyer makes in Thailand. The two paths have different price entry points, different payment schedules, different risk profiles, and different post-purchase experiences. The marketing emphasizes the upside of each — early-stage off-plan pricing on one side, “see what you’re buying” certainty on the other — and underemphasizes the trade-offs.
This article compares both at the dimensions that actually matter for foreign buyers in Phuket.
What each one actually is
Off-plan: buying a property that doesn’t exist yet, or is partially constructed, directly from the developer. Payment is structured around construction milestones — reservation deposit, contract signing, foundation, structure, roof, finishes, transfer. The full price is paid over 18–36 months. The buyer takes occupancy at completion.
Resale: buying a completed property from a current owner — individual or corporate. Reservation, due diligence, SPA, and transfer take 4–8 weeks. Full price is paid at the Land Office on transfer day. The buyer takes occupancy immediately.
Both routes apply to condos, villas, and townhouses. Both routes use the same ownership structures (freehold for condos within quota; leasehold + superficies for villas).
Side-by-side comparison
| Dimension | Off-plan | Resale |
|---|---|---|
| Price (relative to completion) | Meaningful discount at early-stage launch | Market price |
| Time from offer to keys | 18–36 months | 4–8 weeks |
| Payment structure | 5–8 staged milestones over construction | Reservation + deposit + balance at transfer |
| Capital deployment | Gradual | Lump sum |
| Specifications visible | Floor plan, materials list, show unit | Actual unit |
| Build quality verifiable | No (only at completion) | Yes (inspection) |
| Defect warranty | Typically 1 year finishes, 5 years structure | Sold “as is” — no warranty |
| Developer/seller risk | High — developer can fail | Low — seller is just transferring |
| Foreign quota timing | Risk that quota fills before your registration | Quota status known at signing |
| Customization | Possible (specs, finishes, sometimes layout) | None |
| Typical buyer | Long-horizon, risk-tolerant, cash-rich | First-time, immediate-use, lower-risk |
Off-plan — what you’re actually buying
When you sign an off-plan SPA, you’re buying a contractual right to receive a specified property at a specified time, in exchange for a series of payments. You’re not buying a building; you’re buying a promise.
The promise is backed by:
- The developer’s obligation to perform — enforceable in Thai courts, but slow and depending on developer assets
- The reservation and deposit you pay — ideally protected by escrow under the Real Estate Escrow Account Act 2008, but escrow is optional and not all developers use it
- The land the project is being built on — owned by the developer (or under arrangement); a defaulting developer’s land can be claimed by creditors and the project can stall indefinitely
The strength of the promise depends on the developer. A first-tier Phuket developer with 20+ years and 30+ completed projects (Sansiri, Singha, Banyan Tree, Botanica, Boutique Corporation) gives a strong promise. A boutique developer with one or two prior projects gives a weaker promise. A new developer with no track record gives essentially no promise.
Off-plan payment schedule — illustrative
The structure of a typical Phuket off-plan payment schedule:
| Stage | Trigger |
|---|---|
| Reservation fee | Property reserved |
| Contract signing | SPA signed, due diligence complete (largest single milestone) |
| Foundation completion | Construction milestone |
| Structure completion | Construction milestone |
| Roof completion | Construction milestone |
| Wall and finishing | Construction milestone |
| Transfer of ownership | Land Office registration (final balance) |
The exact percentages and number of milestones vary by developer — some compress to fewer milestones, some stretch to more. The buyer’s deposits typically reach the substantial majority of the price by the time the unit is structurally complete; the remainder is paid at transfer. Verify the specific schedule for any project before signing.
Off-plan risks specific to foreign buyers
1. Foreign quota timing. For condos, the 49% foreign cap applies at registration, not at SPA signing. If the building reaches 49% before your transfer day, your registration is refused. The SPA should specify the refund mechanism if this happens.
2. Specification slip. “Subject to revision” clauses in the SPA can permit the developer to change finishes, brand of fixtures, common area amenities, or even unit layout during construction. Push to lock specifications at signing — at least the major items (kitchen brand, flooring grade, bathroom fixtures, ceiling height).
3. Completion delay. Phuket has multiple cases of off-plan projects significantly delayed beyond the original schedule — sometimes by years. The SPA should include a per-day or per-month penalty for delay and a refund mechanism if delay exceeds an agreed threshold (typically a year past original completion).
4. Construction quality risk. You don’t see the actual quality until the project is complete. By then most of the price is paid and your leverage is gone. Mitigations: visit other completed projects by the same developer; have a snagging inspector verify each milestone payment is justified by actual progress; structure the final payment as escrow released only after completion of a punch list.
5. Off-plan resale before completion. A buyer who wants to exit before completion — for personal reasons or because the project is troubled — faces a much smaller buyer pool. Some developers permit reassignment with a fee (typically a small percentage of the price); some prohibit it. The reassigned buyer also takes the residual developer risk, so resale before completion is typically at a discount.
Resale — what you’re actually buying
A resale purchase is conceptually simpler — you’re buying an existing asset from an existing owner. The price visibility, build quality verifiability, and immediate use are real advantages.
The trade-offs:
- No staged payments — the full price is committed at signing/transfer with no milestone protection
- No defect warranty — sold “as is”; problems discovered post-transfer are the buyer’s
- No new-construction discount — paying market price for a known asset
- Inherited issues — building age, deferred maintenance, project-level capital projects coming due, established juristic-person dynamics
For foreign buyers, the resale path is the lower-risk default. The catastrophic failures (developer bankruptcy, never-completed project, indefinitely-delayed transfer) don’t happen in resale. The smaller failures (defects, deferred maintenance, project-level surprises) are catchable in due diligence.
Resale-specific items
1. Building age. A 20-year-old condo has different economics from a 5-year-old one. The juristic-person sinking fund may be inadequate; the building may need re-painting, lift replacement, or major systems work; the property is closer to the end of its useful life. Price should reflect this.
2. Seller’s tax position. If the seller has owned less than 5 years, Specific Business Tax applies (3.3%). If 5+ years, stamp duty applies (0.5%). Customarily seller’s tax, but it shifts negotiation dynamics. Verify with your lawyer who pays which.
3. Existing tenants. A resale of an income-producing property may have tenants in place. Lease rights survive the sale — the new owner takes subject to the registered leases. Verify lease terms, rent levels, and tenant quality before signing.
4. Established management dynamics. The juristic person, building management, and resident dynamics are visible and assessable in resale. Walk the building at off-peak hours, talk to a security guard, ask the juristic about pending issues.
Pricing — how the off-plan discount works
Off-plan pricing is structured to create a discount that compensates for construction risk and capital tied up. Typical Phuket pattern:
- Early phase launch (foundation phase): meaningful discount to projected completion price
- Mid-construction: smaller discount as risk diminishes
- Near-completion: minimal discount; you’re paying near-resale prices but still taking residual completion risk
- Resale immediately post-completion: market price (or slightly above, due to “new building” premium)
The discount narrows as construction risk diminishes. The actual discount at any phase varies by developer and market conditions; verify with comparable resales in the same building or area.
For the discount to actually be value, three things must hold:
- The project completes (no developer failure)
- The project completes on schedule (no extended delay)
- The market hasn’t softened during the build period (price actually reaches projected completion level)
Phuket’s 2024 condo supply +148% YoY makes condition 3 less reliable for current launches. Mass-market condos launching in 2025–2026 may not appreciate to projected completion prices given the supply overhang. Premium villas in established areas remain better positioned for the discount to translate to real value.
When off-plan makes sense
Three buyer profiles where off-plan is the right choice:
1. Long-horizon investor with diversified position. A buyer who can absorb a single project failure within a broader portfolio, has 18–36 months to wait, and wants the early-stage pricing. The risk of any single off-plan project is real but manageable across multiple investments.
2. Buyer wanting specific specifications or customization. Off-plan lets you choose finishes, sometimes layout modifications. For a buyer with specific design requirements, this is valuable.
3. Buyer locked into a specific development. When the buyer wants a unit in a specific upcoming project (branded residence, prime location, specific developer they trust) and there’s no resale inventory, off-plan is the only path.
For these profiles, the developer due diligence becomes more important than the property due diligence:
- Developer’s other completed projects — visit at least one, talk to current owners
- Developer’s financial standing and project financing
- Escrow arrangements for buyer deposits
- Track record on delays and dispute resolution
When resale makes sense
Resale is the lower-risk default for most foreign buyers in Phuket. Specifically right for:
1. First-time foreign buyer in Thailand. The standard transaction sequence (How to buy property in Thailand — step-by-step guide for foreigners) is shorter and lower-risk in resale. Make your first Thailand transaction the simpler one.
2. Buyer wanting immediate use. Personal residence with target move-in date in the next few months. Off-plan typically can’t deliver this.
3. Buyer seeking known income. A resale rental property has known rental history, known costs, and existing tenant relationships. Off-plan rental projections are estimates.
4. Buyer with cash discipline issues. The lump-sum payment in resale forces a disciplined commitment. The staged payments in off-plan can lull buyers into committing to projects they couldn’t afford to complete on a lump-sum basis.
Hybrid — newly-completed buildings
A resale of a newly-completed building (1–3 years old, original developer-purchased units flipping to resale market) often offers the best of both worlds: build quality verifiable, immediate use, current developer warranty potentially still in force, but at resale-market pricing. Worth considering when the off-plan/resale framing forces a binary choice.
What this means for buyers in 2026
Three rules:
-
Default to resale unless there’s a specific reason for off-plan. First-time foreign buyers in Phuket should make their first transaction a resale. Get familiar with the market and process before taking on developer risk.
-
For off-plan, the developer matters more than the property. Spend more time on developer due diligence than on the unit specs. A first-tier developer with a mediocre unit is safer than a marginal developer with an exceptional unit.
-
Lock specifications and timeline penalties in the SPA. “Subject to revision” and unlimited delay tolerance are the two biggest off-plan risks. Both are fixable in contract drafting if you push.
