The Buyer's Agent: Scope of Duty
When a property agent is engaged by a buyer, the agent acts as the buyer's representative and owes the buyer duties under the Estate Agents Act and CEA guidelines. These duties include:
- Fiduciary loyalty — the agent must act in the buyer's best interests and not in any way that conflicts with those interests
- Disclosure — material facts the agent knows or ought to know that would affect the buyer's decision must be disclosed
- Competence — the agent must apply reasonable professional knowledge and skill throughout the transaction
- Confidentiality — the buyer's budget, motivations, and personal information must not be shared with sellers or seller's agents without the buyer's consent
Before the Search: Financing Qualification
One of the most important early duties of the buyer's agent is to ensure the buyer understands their financing position before they fall in love with a property they cannot afford to complete.
In-Principle Approval Before OTP
The agent should strongly advise — and ideally confirm — that the buyer has obtained an In-Principle Approval (IPA) from a bank before exercising any OTP. An IPA is a conditional loan offer that tells the buyer how much the bank will lend. Exercising an OTP without an IPA exposes the buyer to losing the option fee if financing falls through.
Advise on Borrowing Limits
The agent should explain the key financing constraints to the buyer:
- LTV limits — loan-to-value limits depend on the number of outstanding home loans and property type (HDB vs private). First loan with no outstanding loans: up to 75% LTV for private property, 80% HDB loan for HDB purchase. Second loan: 45% LTV.
- TDSR — Total Debt Servicing Ratio cannot exceed 55% of gross monthly income. This limits how much the bank will lend regardless of LTV.
- MSR for HDB and executive condominiums — Mortgage Servicing Ratio must not exceed 30% of gross income for HDB flat loans and ECs during the MOP period.
Advising on Stamp Duty Exposure
Before a buyer commits to an OTP, the agent must ensure the buyer understands their stamp duty liability. Miscalculating stamp duty is one of the most common sources of post-OTP financial surprises.
Buyer's Stamp Duty (BSD)
BSD applies to all purchasers of Singapore property. The tiered rates for residential property (as at 2026):
| Purchase price / market value | BSD rate |
|---|---|
| First S$180,000 | 1% |
| Next S$180,000 | 2% |
| Next S$640,000 | 3% |
| Next S$500,000 | 4% |
| Next S$1,500,000 | 5% |
| Remaining amount | 6% |
Additional Buyer's Stamp Duty (ABSD)
ABSD applies on top of BSD and is highly dependent on the buyer's citizenship status and property count. Key rates as at 2026:
- Singapore Citizens — 0% on first residential property, 20% on second, 30% on third and beyond
- Singapore PRs — 5% on first, 30% on second, 35% on third and beyond
- Foreigners — 60% on any residential property (subject to limited exemptions for nationals of certain FTA countries)
- Entities (companies) — 65% on any residential property
The agent must confirm the buyer's citizenship/PR status and count their existing residential properties before advising on ABSD. Failure to correctly assess ABSD exposure can result in the buyer being surprised by a six- or seven-figure stamp duty bill.
OTP Review Before Exercise
When the seller's agent presents an OTP, the buyer's agent should review it with the buyer before the option fee is paid. Key terms to check:
- Option fee and exercise fee — typically 1% option fee + 4% on exercise for private property; S$1,000 for HDB resale
- Option expiry — the standard OTP for private property gives the buyer 14 days to exercise; HDB resale OTP gives 21 days
- Completion timeline — standard private property completion is 10–12 weeks from OTP exercise (longer for new launches); HDB resale completion is 6–8 weeks after HDB approval
- Vacant possession date — confirm when the seller will deliver vacant possession
- Encumbrances — the OTP should state the property will be delivered free from encumbrances (mortgages, charges, caveats). Flag any deviations.
- Included/excluded fixtures — clarify what fittings (aircons, built-in wardrobes, appliances) are included in the sale price
Conflict of Interest Management
Conflict of interest is one of the most significant obligations for a buyer's agent. Situations requiring disclosure and management:
Co-Broking Arrangements
When the buyer's agent is co-broking with the seller's agent (i.e., the seller's agent is sharing commission with the buyer's agent), this must be disclosed to the buyer. The buyer should understand that the buyer's agent is receiving remuneration from or through the seller's side of the transaction.
Related Party Transactions
If the agent has any personal or financial interest in the property being sold (e.g., the agent is the seller, or the agent has a referral relationship with the developer), this must be disclosed in writing before the buyer proceeds.
Dual Representation
A buyer's agent must not simultaneously represent the seller in the same transaction without informed written consent from both parties. Even with consent, dual representation creates a fundamental conflict. CEA guidelines strongly discourage it, and most agents avoid it entirely.
During the Transaction: Completion Guidance
After OTP exercise, the buyer's agent should help the buyer navigate the completion process:
- Remind the buyer to instruct a conveyancing solicitor promptly after OTP exercise — the buyer's solicitor handles BSD/ABSD payment, mortgage documentation, CPF Board requests, and title registration
- Follow up on IPA conversion to formal loan offer — banks typically issue a formal Letter of Offer after receiving the OTP
- Coordinate the pre-completion inspection (final inspection before keys are handed over) — accompany the buyer and document any outstanding defects agreed to be rectified by the seller
- Assist with key collection and utility transfer on completion day
What the Buyer's Agent Must Not Do
- Withhold material information about the property or the seller from the buyer — active concealment or misrepresentation is both a CEA disciplinary matter and potentially fraudulent
- Share the buyer's budget with the seller's agent — if the buyer tells the agent their maximum is S$2.5M, that information must be kept confidential
- Pressure the buyer to proceed or proceed quickly to earn commission — the buyer's timeline and comfort are the priority
- Accept payment from the seller or the seller's agent without full disclosure to and consent from the buyer
- Advise on specific loan products, insurance products, or legal strategies that require professional licensing
Frequently Asked Questions
Q: Does the buyer's agent owe any duties to the seller?
A: No. The buyer's agent owes duties to the buyer as their client. They owe the seller honest dealing and must not engage in misrepresentation, but their primary duty of loyalty and disclosure runs to the buyer. This is why dual representation is problematic — the agent cannot owe full fiduciary duty to both sides simultaneously.
Q: What happens if the buyer's agent gives wrong ABSD advice and the buyer suffers a loss?
A: If an agent negligently advises a buyer that ABSD does not apply when it does, and the buyer suffers loss as a result, the agent may be liable for that loss in tort. CEA may also take disciplinary action. Agents should always calculate ABSD using current official rates and confirm the buyer's citizenship status and existing property count in writing.
Q: Can a buyer's agent recommend a specific mortgage broker or solicitor?
A: Yes — agents can provide referrals to mortgage brokers and conveyancing solicitors. However, if the agent receives a referral fee for making the introduction, this must be disclosed to the buyer. The buyer must make their own decision on which professionals to engage.
Q: Is the buyer's agent required to attend the completion?
A: There is no legal requirement for the agent to attend completion, which is typically handled by solicitors. However, good practice is to coordinate the key handover with the buyer present and to confirm that the property is in the agreed condition. Attending or arranging a pre-completion inspection is strongly advisable.
