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 is the difference between off-plan and resale property in Thailand?
An off-plan purchase is a contract with a developer for a property under construction, while a resale purchase transfers a completed property from its current owner. Off-plan payments follow contractual construction milestones and occupancy comes at completion. Compare the early-stage price against completed-stock pricing in the Phuket quarterly property market report.
A resale purchase follows reservation, due diligence, a Sale and Purchase Agreement (SPA) and Land Office transfer. The buyer can inspect the property before committing the full price and can use it after transfer.
Both routes apply to condos, villas, and townhouses. Both routes use the same ownership structures (freehold for condos within quota; leasehold + superficies for villas).
How do off-plan and resale purchases compare?
Off-plan trades an inspectable completed property for staged payments, potential customization and developer risk. Resale offers immediate inspection, known condition and payment at transfer.
| Dimension | Off-plan | Resale |
|---|---|---|
| Price (relative to completion) | Meaningful discount at early-stage launch | Market price |
| Time from offer to keys | Construction period | Available after transfer |
| Payment structure | 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 | Contractual warranty | 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 |
What am I buying when I buy off-plan property?
You are buying a contractual right to receive a specified property at a specified time in exchange for a series of payments, not a completed building.
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 that promise depends on the developer’s financial position, completed projects, financing and history of delays or disputes.
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. Off-plan projects can be significantly delayed beyond the original schedule. The SPA should include a delay penalty and a refund mechanism if delay exceeds an agreed threshold.
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 for a fee and some prohibit it. The reassigned buyer also takes the residual developer risk, so resale before completion is often at a discount.
What am I buying in a resale property purchase?
A resale purchase transfers an existing asset from its current owner, so you can assess its price, build quality and immediate use before transfer.
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. Older buildings can have an inadequate juristic-person sinking fund, pending re-painting, lift replacement or major systems work. The price should reflect this.
2. Seller’s tax position. Specific Business Tax and stamp duty can affect the negotiation. Verify with your lawyer which tax applies and who pays it.
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.
How does off-plan pricing compare with resale prices?
Off-plan pricing can discount a future completed property to compensate for construction risk and capital tied up before delivery, but the discount is not a guaranteed gain.
- 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)
Compare the proposed price with completed resales in the same area or building. For rental-income evidence rather than a projected yield, see Rental yields in Phuket — what investors actually earn.
Who is off-plan property right for, and who might it not be the right fit for?
Off-plan suits a long-horizon buyer who can absorb construction and developer risk, wants a particular new project or values customization. It might not be the right fit for a buyer who needs immediate use, an inspectable building or the lowest-risk transaction.
1. Long-horizon investor with a diversified position. A buyer who can absorb a single project failure within a broader portfolio and wants the early-stage pricing.
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 seeking a specific upcoming project. When a buyer wants a unit in a particular new project and no resale inventory exists, off-plan is the available 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
Who is resale property right for, and who might it not be the right fit for?
Resale suits a buyer who wants known condition, immediate use or an established rental history. Off-plan might be the right fit instead for a buyer who values customization or can accept a longer construction horizon.
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. A personal residence with a near-term move-in date. Off-plan cannot deliver this immediately.
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.
Should I consider a newly completed resale property?
Yes. A resale in a newly completed building can combine verifiable build quality and immediate use with a developer warranty that may still apply, although it is priced as a resale rather than an early-stage launch.
How should I choose between off-plan and resale property in Thailand?
Choose resale when you need a known, inspectable property and use off-plan only when its staged payment, customization or project-specific benefits justify the extra developer and construction risk.
-
Start with resale when lower risk matters most. A first-time foreign buyer can learn the market and process without taking on developer risk.
-
For off-plan, investigate the developer as closely as the property. Spend at least as much time on financial standing, completed projects, financing and contract protections as on unit specifications.
-
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.
