Paper 2 · Private Sale
Sale of Uncompleted Private Property (New Launches)
A new launch is the sale of an uncompleted (under-construction) private residential property directly by a licensed housing developer. Unlike a resale, the buyer is committing to a home that does not yet physically exist, so the law wraps the transaction in a set of statutory protections — a sale licence, prescribed forms, staged payments and a ring-fenced project account. This lesson covers the framework you need for RES Paper 2 and how it differs from a completed/resale deal.
The regulatory framework
The sale of uncompleted private residential property is governed by the Housing Developers (Control and Licensing) Act and its rules. For commercial uncompleted property, the equivalent regime is the Sale of Commercial Properties Act. A developer building units for sale must hold a valid sale licence (or the relevant approval/exemption) before marketing and selling.
- The developer must be licensed and comply with the applicable Act before selling uncompleted units.
- Sales must be documented using prescribed statutory forms — the buyer cannot be asked to waive the built-in protections.
- A project account must be maintained so that buyers' monies are ring-fenced for the project.
- Always confirm the current licence status, rules and any thresholds with the developer, CEA or the relevant authority.
Prescribed forms: OTP and S&P
New launches use prescribed forms with buyer protections built in — you cannot substitute a private template. The two key documents are the statutory Option to Purchase (OTP) and the Sale and Purchase Agreement (S&P) in the standard prescribed form. On booking, the buyer pays a booking fee and is issued the OTP; the developer must then deliver the S&P for the buyer's exercise. Because the S&P is in a standard statutory form, terms such as construction milestones, timelines and buyer remedies are largely fixed by law rather than freely negotiated.
- Booking fee — 5% of the purchase price, paid on the grant of the OTP. It must be paid in cash; CPF and the bank loan cannot be used at this stage.
- The developer must deliver the S&P within 14 days of granting the OTP.
- The buyer then has 3 weeks (21 days) from receipt of the S&P to exercise the Option by signing and returning it.
- If the buyer does not exercise, the developer may forfeit 25% of the booking fee and must refund the remaining 75% — so on a $2m unit the $100,000 booking fee costs $25,000 to walk away from, not the whole sum and not nothing.
| Feature | New launch (uncompleted) | Resale (completed) |
|---|---|---|
| Seller | Licensed housing developer | Private individual owner |
| Documents | Prescribed statutory OTP + standard S&P | Private OTP + completion |
| Payment | Progressive (or deferred, where offered) | Deposit + balance on completion |
| Monies protected by | Project account | Solicitors' conveyancing process |
| Typical completion | On TOP / CSC of the project | Roughly 8–10 weeks after option exercised |
Progressive Payment Scheme (Normal)
Under the Progressive Payment Scheme (Normal), the buyer pays the purchase price by instalments tied to construction milestones. The percentages are prescribed by the Housing Developers Rules, not set by the developer, so they are the same on every project — only the timing differs. The buyer's housing loan is drawn down progressively, so interest accrues only on the amount disbursed so far, keeping early cashflow relatively low.
| Stage | % of purchase price | Cumulative |
|---|---|---|
| Booking fee, on grant of the OTP (cash) | 5% | 5% |
| On signing the S&P — within 8 weeks of the OTP | 15% | 20% |
| Completion of the foundation work | 10% | 30% |
| Completion of the reinforced concrete framework of the unit | 10% | 40% |
| Completion of the partition walls of the unit | 5% | 45% |
| Completion of the roofing / ceiling of the unit | 5% | 50% |
| Completion of door and window frames, electrical wiring, internal plastering and plumbing | 5% | 55% |
| Completion of the car parks, roads and drains serving the project | 5% | 60% |
| On TOP (notice of vacant possession) | 25% | 85% |
| On CSC / legal completion | 15% | 100% |
The 3 weeks and the 8 weeks are two different clocks, and mixing them up is a common slip: the 3 weeks is the buyer's window to *exercise* the Option once the S&P is delivered, while the 8 weeks from the OTP is when the 15% instalment falls due. Beyond that, two numbers carry most of the marks: the 25% on TOP — the single largest instalment, and the point at which the loan is nearly fully drawn — and the 15% retained until CSC, which is the buyer's leverage while the developer closes out the project. Note also that only 20% is payable before any construction milestone falls due.
Deferred Payment Scheme
Where a developer offers it, the Deferred Payment Scheme (DPS) lets the buyer pay a booking amount up front and defer the bulk of payment until later (often around TOP/completion). The trade-off is typically a higher price in exchange for the deferred cashflow. Availability of DPS varies by project and over time, so its terms, pricing and any conditions must be confirmed with the developer.
The trap
Do not assume the booking fee is always fully refundable — and do not assume it is wholly forfeit either. If the buyer lets the OTP lapse without exercising it, the developer keeps 25% of the booking fee and refunds 75%. Both extremes are wrong answers: never promise a client a full refund, and never tell them the whole 5% is gone.
TOP vs CSC and the defects liability period
Two completion milestones often confuse candidates. TOP (Temporary Occupation Permit) certifies that the building is safe to be occupied — buyers can typically take possession and move in at this stage, and it is when the 25% instalment falls due. CSC (Certificate of Statutory Completion) is the final legal completion, issued after all outstanding requirements are met, and carries the final 15%. TOP means occupiable; CSC means fully legally complete — they are not the same.
The defects liability period under the prescribed S&P is 12 months from the date the buyer receives the Notice of Vacant Possession — not from CSC. Within that window the developer must make good, at its own cost, any defect that becomes apparent. Once notified in writing the developer has 1 month to rectify; if it does not, the buyer may obtain a contractor's quotation, serve it on the developer, and the developer has a further 14 days to act before the buyer may carry out the works and recover the cost.
Exam takeaway
New launches are developer sales of uncompleted homes, licensed under the Housing Developers (Control and Licensing) Act (or the Sale of Commercial Properties Act for commercial), documented on prescribed OTP and S&P forms, with buyers' monies protected by a project account. Memorise the spine of the deal: 5% booking fee in cash → S&P within 14 days → exercise within 3 weeks (or forfeit 25% of the booking fee) → 15% at signing → milestone instalments → 25% at TOP → 15% at CSC, with a 12-month defects liability period running from the Notice of Vacant Possession.
Edge cases to watch
- Progressive vs deferred cashflow and interest — progressive spreads payments and interest over the build; deferred pushes payment later but usually at a higher price.
- Booking-fee refund/forfeiture — 25% forfeited, 75% refunded if the buyer does not exercise the OTP.
- Financing draws down progressively — the loan (and interest charged) grows in step with milestones, not all at once.
- TOP vs CSC — occupation is possible at TOP (and 25% falls due), but full legal completion, and the last 15%, come only at CSC.
- Buying at launch vs on completion — launch prices/units differ from what may remain once the project is completed; risk, choice and pricing all shift.
- Defects liability period — 12 months from the Notice of Vacant Possession; advise buyers to inspect and report defects in writing well inside that window.
Worked case study · Section B style
Your client is buying an uncompleted condominium unit directly from a licensed developer at a new launch. She has paid the booking fee and received the Option to Purchase. She asks you what document she will use to formally commit to the purchase and how she will pay for the unit as it is built.
- A.A privately drafted OTP and a lump-sum payment on completion, like a resale.
- B.The prescribed standard-form Sale and Purchase Agreement, with payment typically by instalments tied to construction milestones.
- C.No further documents are needed; the booking fee alone completes the purchase.
- D.A tenancy agreement, with rent paid monthly until TOP.
Show answer & explanation
Answer: B. Uncompleted private property sold by a licensed developer uses the prescribed statutory S&P (not a private template), and payment is normally made under the Progressive Payment Scheme — instalments tied to construction milestones — with the loan drawn down progressively. A deferred scheme may be available on some projects. A lump-sum-on-completion model describes a resale, and a booking fee alone does not complete the purchase. Confirm current scheme terms and any refund/forfeiture rules with the developer.
Apply it · the IRAC method
A buyer is interested in an uncompleted unit at a new condominium launch. The developer's sales agent hands over an Option to Purchase and asks for a booking fee, and the buyer asks when and how the rest of the price is payable.
- IIssue: What legal framework governs the sale of the uncompleted unit, and how will payment be structured before the buyer can occupy?
- RRule: The sale of uncompleted residential units by a developer is governed by the Housing Developers (Control and Licensing) Act and its rules. A licensed developer must use the standard-form Option to Purchase and Sale & Purchase Agreement prescribed by the Controller of Housing. The booking fee is 5% of the purchase price in cash; the developer must deliver the S&P within 14 days, and the buyer has 3 weeks from receipt to exercise, failing which 25% of the booking fee is forfeited and 75% refunded. Payment then follows the Progressive Payment Scheme at percentages prescribed by the Rules, ending with 25% on TOP and 15% on CSC. Buyers can take possession at Temporary Occupation Permit (TOP), while the Certificate of Statutory Completion (CSC) is issued later. (Confirm the current prescribed form with the Controller of Housing.)
- AApplication: Because the unit is uncompleted, the developer must hold a sale licence and use the statutory standard OTP and S&P, not a freely drafted contract. The booking fee the agent is asking for is the prescribed 5%, and it buys the buyer a 3-week decision window rather than an immediate commitment. The balance is not paid in one lump sum: under the Progressive Payment Scheme, 15% falls due on signing the S&P and the remainder as stages (foundation, reinforced concrete framework, walls, roofing, finishes, car parks) are certified complete. The buyer may move in at TOP, when the largest single instalment of 25% falls due, with the final 15% at CSC.
- CConclusion: Advise the buyer that the transaction is protected under the Housing Developers Act using standard-form documents, that only 20% is payable before construction milestones begin, that payment is progressive and milestone-based, and that occupation is possible from TOP while CSC and the last 15% come later. Flag the 25% forfeiture if she books and then does not exercise, and the 12-month defects liability period running from the Notice of Vacant Possession.

Practise Private Sale questions →Common questions
- What is the difference between the Progressive Payment Scheme and the Deferred Payment Scheme?
- Under the **Progressive Payment Scheme (Normal)**, the buyer pays instalments **tied to construction milestones** at percentages prescribed by the Housing Developers Rules: **5%** booking fee, **15%** on signing the S&P, **10%** on foundation, **10%** on the reinforced concrete framework, **5%** each on partition walls, roofing, internal finishes and the car parks/roads/drains, **25%** on TOP and the final **15%** on CSC. The loan is drawn down progressively, so interest accrues only on what has been disbursed. The **Deferred Payment Scheme**, where offered, lets the buyer pay most of the price later, usually at a **higher price**; availability and terms vary by project.
- Is a booking fee for a new launch refundable if the buyer changes their mind?
- Only partly. The booking fee is **5% of the purchase price**, paid in cash on the grant of the OTP. If the buyer does not exercise the Option within **3 weeks** of receiving the S&P, the developer is entitled to forfeit **25% of the booking fee** and must refund the remaining **75%**. So it is neither fully refundable nor wholly forfeit — never tell a client either.
- What is the difference between TOP and CSC?
- **TOP (Temporary Occupation Permit)** allows the building to be **occupied** — buyers can typically move in, and the **25%** instalment falls due. **CSC (Certificate of Statutory Completion)** is the **final legal completion** of the project, issued after outstanding requirements are met, and carries the final **15%**. The **defects liability period** is **12 months from the date the buyer receives the Notice of Vacant Possession**, during which the developer must make good defects at its own cost.
