The OTP Structure: Two Stages, Two Commitments
A private property Option to Purchase (OTP) involves two financial commitments:
- Option fee (typically 1%): Paid by the buyer when the seller grants the OTP. This fee is non-refundable if the buyer does not exercise the option before it expires.
- Exercise fee (typically 4%): Paid by the buyer when exercising the OTP within the option period (typically 14 days). Together with the option fee, this creates a 5% deposit and converts the OTP into a binding S&P contract.
For HDB resale transactions, the HDB Resale Portal prescribes the option fee ($1,000 for flats priced below $1,000,000 or $5,000 above that threshold) and the exercise fee (up to 5% of agreed price minus the option fee, subject to HDB limits).
Scenario 1: Buyer Does Not Exercise the OTP (Lapsed Option)
If the buyer pays the 1% option fee but does not exercise the OTP before it expires:
- The OTP lapses automatically — no legal action is required by either party
- The seller retains the 1% option fee as compensation
- The seller is free to re-market the property and grant a new OTP to another buyer
- The buyer has no further obligation to the seller
The option fee represents the buyer's cost of locking up the seller during the option period. Losing 1% on a $1,500,000 property is $15,000 — a significant but limited loss.
Scenario 2: Buyer Exercises Then Cannot Complete
If the buyer exercises the OTP (paying the 4% exercise fee) but subsequently cannot complete the purchase — most commonly because financing falls through, circumstances change, or the buyer simply changes their mind:
- The entire 5% deposit (option fee + exercise fee) is forfeited to the seller
- The seller may also sue for specific performance (a court order requiring the buyer to complete) or damages exceeding 5% if the seller's actual loss is greater
- If the seller resells at a lower price, the seller may claim the difference in price as additional damages
- BSD already paid by the buyer on the exercised S&P Agreement may be refunded by IRAS if the transaction does not complete — subject to application within the prescribed period
Scenario 3: Seller Refuses to Honour the Granted OTP
If a seller grants an OTP and then refuses to proceed — refusing to hand over keys, refusing to sign the S&P, or accepting a higher offer from another buyer:
- The buyer can sue for specific performance — seeking a court order requiring the seller to complete the sale on the agreed terms
- If the court awards specific performance, the seller must sell at the original OTP price regardless of subsequent market movement
- Alternatively, the buyer can accept the return of the option fee and sue for damages (including any costs incurred and losses from not acquiring the property)
- The seller cannot simply return the 1% fee and walk away without legal consequence once the OTP has been granted
HDB-Specific Default Consequences
For HDB resale transactions, the HDB Resale Portal and standard OTP form govern the process:
- If the buyer does not exercise the HDB OTP, the option fee is forfeited to the seller
- If the buyer exercises but HDB later rejects the application (e.g., buyer is ineligible), the transaction cannot proceed — HDB's standard terms provide for return of the option and exercise fees in this scenario, subject to HDB's determination
- If the seller refuses to proceed after the OTP has been exercised, HDB may intervene and the buyer retains legal remedies as for private property
Agent Obligations Around OTP Execution
Agents have professional obligations to advise clients on the consequences of signing or not signing at each stage:
- Advise buyers to confirm IPA before granting any option fee
- Advise sellers not to grant OTPs to multiple buyers simultaneously — the second OTP creates competing obligations
- Document all communications around OTP terms in writing
- Never alter OTP terms (price, completion date) without new documentation signed by both parties
- If a client intends to pull out after exercising, advise them to consult a solicitor immediately rather than simply going silent
Q: Can a buyer get the 5% deposit back if the property has a serious defect discovered after exercise?
A: Misrepresentation or concealment of a material defect by the seller may give the buyer grounds to rescind the contract and recover the deposit. However, the general rule in Singapore is caveat emptor — the buyer is responsible for inspecting the property before signing. Patent defects (visible on inspection) are generally not grounds for rescission. Latent defects (hidden defects the seller knew about) may be, but this requires legal advice and potentially litigation.
Q: What happens to ABSD already paid if the deal falls through after exercise?
A: ABSD paid can be refunded by IRAS if the S&P is subsequently rescinded, cancelled, or the transaction does not complete. The buyer must apply to IRAS for the refund within the prescribed period (typically 6 months from rescission). BSD may also be refunded on the same basis. IRAS processes these refund applications on a case-by-case basis.
Q: If a seller grants two OTPs for the same property, what happens?
A: Both OTPs are valid binding obligations. If the first buyer exercises, the seller is contractually obligated to sell to them. If the second buyer also exercises (having not been told the property was already under OTP), the seller faces simultaneous obligations to two buyers and potential liability to both. Granting overlapping OTPs is a serious professional and legal breach — CEA rules prohibit agents from facilitating this.
