What Is an Option to Purchase?
An Option to Purchase (OTP) is a legal document issued by the seller to the buyer that grants the buyer the exclusive right — but not the obligation — to purchase a private residential property at an agreed price within a specified period. In Singapore's private property market, the OTP is the standard instrument for initiating a sale. It is distinct from the Sale and Purchase Agreement (S&P), which is a binding contract for both parties and is executed when the buyer formally exercises the option.
The OTP process for private residential property in Singapore is governed by convention and, in many cases, the standard Law Society of Singapore conditions of sale, which most private property transactions adopt by reference. CEA-registered agents representing buyers or sellers must understand each stage of the process to guide clients correctly and avoid costly errors.
Stage 1: Granting the OTP — Option Fee and Exclusivity
When a buyer and seller agree on a price, the seller grants an OTP to the buyer. The buyer pays an option fee to the seller, which is typically 1% of the agreed purchase price. This fee is paid as consideration for the seller's commitment to keep the property off the market for the option period. The option fee is non-refundable if the buyer does not exercise the option within the stipulated period.
The option fee is negotiable. In practice, 1% is the market convention for private residential property. Some sellers accept a lower option fee (S$5,000 flat for lower-priced properties) and some buyers offer a higher fee to demonstrate commitment in competitive offer situations. The option fee is subsequently credited toward the purchase price on completion.
Stage 2: The 14-Day Option Period
Once the OTP is granted, the buyer has a standard 14-day option period (unless a different period is negotiated) to decide whether to exercise. During this time, the buyer should:
- Conduct legal due diligence: Engage a conveyancing lawyer to review the title search, check for encumbrances (mortgages, caveats, restrictions), and advise on any issues with the property.
- Obtain in-principle approval (IPA) for financing: If the buyer is using a bank loan, confirm the loan amount and conditions. The formal loan offer letter will follow later, but the IPA provides assurance that financing is achievable.
- Commission a valuation if required: Banks typically require a valuation before approving a loan. If the bank's valuation comes in below the agreed purchase price, the buyer faces a cash-over-valuation (COV) — the shortfall must be funded in cash, as CPF and loan amounts are capped at the lower of purchase price or valuation.
- Calculate stamp duty liability: Buyer's Stamp Duty and Additional Buyer's Stamp Duty (where applicable) must be paid within 14 days of exercising the OTP. Buyers should model this before exercising to ensure sufficient cash is available.
Stage 3: Exercising the Option — 5% Exercise Deposit
To exercise the OTP, the buyer signs the option document and pays the exercise deposit — typically 4% of the purchase price (bringing the total paid to 5% including the 1% option fee). This 5% total represents the deposit under the standard Law Society conditions. The exercise is delivered to the seller's solicitors on or before the expiry of the option period.
If the buyer does not exercise within the option period, the option lapses and the 1% option fee is forfeited to the seller. The seller is then free to re-market the property. In some transactions, the buyer may request an extension of the option period — this requires the seller's agreement and may involve an additional option fee.
Stage 4: The Sale and Purchase Agreement and Conveyancing
Once the option is exercised, the buyer's lawyer and seller's lawyer proceed with the conveyancing process. This involves:
- Title search and requisitions: The buyer's lawyer verifies the title, searches for outstanding maintenance fees, checks for development charges, and raises requisitions with various government authorities (URA, LTA, PUB) for replies on the property.
- CPF withdrawal: If the buyer is using CPF OA funds, the CPF Board must be notified and the relevant CPF charge registered against the property before completion.
- Bank loan documentation: The bank's lawyers will prepare the mortgage documentation. The formal loan offer letter must be accepted by the buyer and the mortgage instrument prepared for registration.
- Completion account: The seller's lawyer prepares a completion account showing the breakdown of the purchase price, deductions (existing mortgage redemption, outstanding maintenance fees, property tax adjustments), and the net proceeds to the seller.
Stage 5: Completion — Standard 12-Week Timeline
The standard completion period for private residential property in Singapore is 12 weeks (approximately 84 days) from the date of the OTP. This timeline is a convention — the parties may agree to a shorter or longer period depending on their circumstances. Common reasons for extended completion:
- The seller needs more time to arrange alternative accommodation.
- The buyer is simultaneously selling another property and requires the proceeds to fund the purchase.
- Complex financing arrangements (bridging loans, CPF property charge releases) require additional time.
On the completion date, the buyer's lawyers pay the balance purchase price (purchase price less the 5% deposit paid on exercise, less any CPF withdrawal applied) to the seller's lawyers. The property title transfers, and the buyer receives the keys.
Agent Responsibilities at Each Stage
CEA regulations require agents to act in the best interests of their client at each stage of the OTP process. In practice, this means:
- Buyer's agent: Ensure the buyer understands the option fee is non-refundable, models stamp duty before exercising, has engaged a lawyer before the option expires, and has confirmed financing availability before the option period runs out.
- Seller's agent: Ensure the OTP terms accurately reflect the agreed price and conditions, that no other OTP is granted for the same property simultaneously, and that the seller understands their obligations during the option period and through to completion.
- Both agents: Lodge a caveat on behalf of the buyer after the OTP is exercised (or promptly after — buyers' lawyers typically do this, but agents should confirm it is done to protect the buyer's interest against subsequent encumbrances or competing sales).
Frequently Asked Questions
Q: What happens if the buyer does not exercise the OTP before it expires?
A: If the buyer does not exercise the OTP within the option period (typically 14 days), the option lapses automatically. The 1% option fee paid to the seller is forfeited — it is non-refundable. The seller is released from the obligation to sell to that buyer and may re-market the property. The buyer has no further claim on the property.
Q: Can the OTP period be extended beyond 14 days?
A: Yes, but only with the seller's agreement. The standard OTP period for private residential property in Singapore is 14 days. If a buyer needs more time — for example, to finalise financing or complete due diligence — they may request an extension from the seller. The seller is not obligated to agree and may request an additional option fee in exchange. Any extension should be documented in writing.
Q: When must stamp duty be paid after exercising the OTP?
A: Buyer's Stamp Duty (BSD) and, where applicable, Additional Buyer's Stamp Duty (ABSD) must be paid to IRAS within 14 days of exercising the OTP for residential property. Late payment attracts interest and penalties. For buyers using CPF or bank financing, the conveyancing lawyer typically arranges stamp duty payment as part of the completion process, but buyers must ensure funds are available within the 14-day window.
Q: What is cash-over-valuation (COV) and how does it affect the OTP?
A: Cash-over-valuation (COV) arises when the agreed purchase price exceeds the bank's or HDB's valuation of the property. For private property, banks and CPF usage are capped at the lower of the purchase price or the bank's valuation. If a buyer agrees to pay S$1.5 million but the bank values the property at S$1.4 million, the S$100,000 COV must be funded entirely in cash — it cannot be financed or paid from CPF. Agents should flag COV risk before the buyer commits to an offer price.
