The Option to Purchase (OTP) Explained — Singapore
For a private resale, the Option to Purchase (OTP) is the contract that locks the deal in place before the formal Sale & Purchase Agreement. It gives the buyer an exclusive right to buy within a set window. The RES exam tests the mechanics and the money at each stage.
The stages, with the money
| Stage | What happens | Money |
|---|---|---|
| Grant of OTP | Seller grants the option; buyer gets exclusive right to buy | Buyer pays Option Fee ≈ 1% |
| Option Period | Commonly 14 days (negotiable, e.g. 21). Seller can't sell to anyone else | — |
| Exercise | Buyer signs the OTP to proceed | Top up to a 5% deposit (i.e. +4%) |
| Completion | Title transfers, keys handed over (~8–12 weeks later, via lawyers) | Pay the balance 95% + stamp duties |
If the buyer doesn't proceed
If the buyer lets the option lapse (doesn't exercise within the period), the OTP simply expires and the Option Fee (~1%) is forfeited to the seller — nothing more. The 5% deposit only becomes relevant once the option is exercised.
Worked example
A $1,500,000 condo: option fee 1% = $15,000 on grant. The buyer exercises and tops up to a 5% deposit = $75,000 total (i.e. +$60,000). At completion they pay the balance 95% (~$1,425,000) plus stamp duties. But if they don't exercise, they lose only the $15,000 option fee — not the $75,000.
New-launch (developer) sales are different
Buying a new launch from a developer doesn't use the 1%/5% resale OTP. The buyer pays a booking fee (commonly 5–10%) to obtain the OTP, and the developer must deliver the prescribed Sale & Purchase Agreement within set timelines; the buyer then has a window to exercise. If the buyer doesn't proceed, the developer may forfeit part of the booking fee (commonly 25%) and refund the rest — a Housing Developers Rules safeguard.
Conditions & sub-sales
- An OTP / S&P can be “subject to” conditions — e.g. subject to financing, or to the sale of the buyer's existing property — letting the buyer withdraw if the condition genuinely fails.
- Reselling an uncompleted unit before completion is a sub-sale — an assignment of the buyer's rights, with its own stamp-duty (and possible SSD) implications.
- There is no statutory cooling-off period for a private resale once the OTP is exercised — the buyer is bound.
Common mistakes
- Thinking the full 5% is forfeited on non-exercise — it's just the 1% option fee.
- Confusing the option period (window to exercise) with the completion period.
- Assuming an HDB resale OTP follows the same 1%/5% rules — it doesn't.
The trap
If the buyer walks away before exercising, only the 1% Option Fee is forfeited — not the full 5%. Exam questions bait you with “how much does the buyer lose?” — it's the 1%. (Note: the HDB OTP works differently — see the HDB resale page.)
Exam takeaway
Keep the timeline straight: Option (1%) → Exercise (top up to 5%) → Completion (balance 95%). The Option Period is the window to exercise, not to complete — completion is a separate, later stage.
Apply it · the IRAC method
A buyer of a resale private condominium pays the seller an option fee and receives an Option to Purchase (OTP). During the option period the buyer changes his mind and does not sign to exercise it, then asks whether he can get his money back.
- IIssue: What is an OTP legally, and what happens to the option fee if the buyer does not exercise the OTP within the option period?
- RRule: An Option to Purchase (OTP) for a resale private property is a contract by which the seller, in return for the option fee, grants the buyer the exclusive right to buy at an agreed price if the buyer exercises the option within the option period (commonly around 14 days) by signing and paying the balance to make up the deposit. Exercising creates a binding sale-and-purchase leading to completion. If the buyer does not exercise, the option lapses and the option fee is generally forfeited to the seller. (Confirm current option period/deposit conventions and any HDB-specific rules with CEA.)
- AApplication: Here the buyer paid the option fee for the right, not the obligation, to buy. By letting the option period pass without exercising, he simply chose not to proceed. There is no binding purchase, but the option fee was the price paid for that right.
- CConclusion: The OTP has lapsed and the buyer is not bound to complete, but the option fee is forfeited to the seller. The salesperson should have made clear before payment that the fee is at risk if the option is not exercised.
Worked case study · Section B style
A seller grants a buyer an OTP on a private condo for a 1% option fee. Two days later a higher offer arrives and the seller wants to switch buyers. • OTP granted, fee paid • Still within the option period
- (i) The OTP is generally irrevocable during the option period
- (ii) The seller cannot withdraw to accept a higher offer during that period
- (iii) The buyer exercises by signing and paying the further sum (commonly 4%) in time
- (iv) The seller may freely sell to the higher bidder despite the OTP
- A.(i), (ii) and (iii) only
- B.(i) and (iv) only
- C.(iii) only
- D.All of the above
Show answer & explanation
Answer: A. (i)–(iii) are correct: the OTP binds the seller for the option period, and the buyer exercises with the further payment. (iv) is the trap.

- How much is the option fee for a private property in Singapore?
- It is typically 1% of the purchase price, though it can be negotiated. On exercising the option the buyer usually tops up to a 5% deposit.
- What happens if the buyer does not exercise the OTP?
- The option simply lapses at the end of the option period and the option fee (typically the 1%) is forfeited to the seller. The larger deposit only comes into play once the option is exercised.
- Is a new-launch OTP the same as a resale OTP?
- No. For a new launch from a developer you pay a booking fee (often 5–10%) and sign the prescribed Sale & Purchase Agreement within set timelines; if you don't proceed, the developer may forfeit part of the booking fee. The 1%/5% structure is for a private resale.
