Sale of Properties Cheat Sheet for RES Exam Revision

This Sale of Properties cheat sheet provides a high-density summary of transaction timelines, Option to Purchase (OTP) rules, and completion stages required for the RES exam. Success in Paper 2 depends on mastering the 14-day private property OTP window and the standard 8-to-12-week completion cycle. For RES exam candidates, this topic falls under Sale of Properties in Paper 2. You can practice questions on this in the Prepare app.

Key timelines to memorize:

• Private Property OTP Validity: Usually 14 days (contractual, can vary).
• HDB OTP Validity: 21 days (fixed by HDB).
• Stamp Duty Payment: Within 14 days of exercising the Option (local) or 30 days (overseas).
• Completion Period: Typically 8 to 12 weeks from the date the Option is exercised.

According to the CEA Annual Report, there are over 33,000 registered property agents in Singapore as of 2026, all of whom must understand these statutory timelines to avoid professional negligence. Navigating the sale of properties requires a precise understanding of the 14-day stamp duty deadline and the 8-to-12-week completion window to ensure a legally compliant transaction process for all clients.

The OTP is a right granted by the seller to the buyer to purchase the property at a fixed price within a specified period. In private residential transactions, the Option Fee is typically 1% of the purchase price, while the Exercise Fee is usually 4%, totaling a 5% cash deposit.

Must-remember facts:

• Forfeiture: If the buyer does not exercise the OTP, the seller usually forfeits the 1% Option Fee.
• HDB Option Fee: Maximum S$1,000.
• HDB Exercise Fee: Maximum S$4,000 (Total deposit not exceeding S$5,000).
• Cooling-off Period: Note that for developers' sales (Project Sales), specific Controller of Housing (COH) rules apply regarding the 3-week period for delivery of the Sale & Purchase Agreement.

Candidates must distinguish between the 1% option fee for private properties and the capped S$1,000 fee for HDB flats to correctly answer Paper 2 calculation questions. The standard 1% option fee and 4% exercise fee structure ensures that a total 5% deposit is secured before the transaction proceeds to the formal completion stage handled by conveyancing lawyers.

Understanding the differences between private and public housing transactions is a core component of the RES exam. While private sales are governed by the Land Titles Act and contractual law, HDB sales must comply with the Housing and Development Act.

Feature	Private Residential	HDB Resale
OTP Period	Commonly 14 days	Fixed 21 days
Option Fee	Negotiable (typically 1%)	Max S$1,000
Deposit	Typically 5% or 10%	Max S$5,000
Valuation	Any time (usually for loan)	After OTP is granted
Approval	Not required	HDB Approval required

As of 2026, the RES exam registration fee is S$408.55 (inclusive of GST), and candidates must achieve a 75% passing threshold (60/80 marks). Mastery of the differences between HDB's 21-day fixed option period and the private sector's negotiable 14-day window is essential for passing the Paper 2 practical transaction section.

In Singapore, the Singapore Academy of Law (SAL) or law firm's conveyancing accounts must hold transaction funds to protect buyers. Under the Conveyancing (Maintenance of Property) Rules, lawyers cannot hold conveyancing money in their normal office accounts.

• Completion: The legal title transfers from the vendor to the purchaser.
• Apportionment: Rates, taxes, and maintenance fees are adjusted between parties as of the completion date.
• Vacant Possession: The seller must hand over the property in the agreed state (usually empty and clean) unless sold with tenancy.

Property agents must ensure that all client monies are handled via crossed cheques or bank transfers to the designated law firm's account. The completion process involves the final transfer of the remaining 95% of the purchase price, usually 8 to 12 weeks after the option is exercised, ensuring the legal title is officially registered under the Land Titles Act.

Stamp duties are a major hurdle in the sale of properties. Candidates must memorize the current rates for Buyer’s Stamp Duty (BSD) and Additional Buyer’s Stamp Duty (ABSD). For more details, see our guide on Property Taxation.

• BSD: Tiered rates (1% on first $180k, 2% on next $180k, up to 6% for residential properties above $3M).
• Seller’s Stamp Duty (SSD): Payable if the property is sold within 3 years (12% in Year 1, 8% in Year 2, 4% in Year 3).
• Late Payment: Penalties apply if not paid within 14 days of the signed document.

According to IRAS, the BSD is calculated based on the purchase price or market value, whichever is higher. Candidates must accurately calculate the tiered BSD rates and identify the 3-year SSD liability period to provide correct tax advice and pass the financial calculation components of the RES Paper 2 exam.

Q: Can a property agent handle transaction money? No. Under the Estate Agents Act (Cap. 95A), agents are strictly prohibited from handling any money related to the sale or lease of property, except for valuation fees or commission.

Q: What is the 'Option to Purchase' validity for HDB? It is strictly 21 calendar days (including weekends and public holidays). It expires at 4:00 PM on the 21st day.

Q: What is the RES exam pass rate? According to CEA data from 2025, the RES exam pass rate is approximately 45%, highlighting the need for rigorous study.

Q: When is the commission payable? Usually upon completion of the transaction or as per the signed Estate Agency Agreement.

Property agents are prohibited from handling client transaction funds under the Estate Agents Act, and they must ensure HDB OTPs are exercised within the 21-day window. Understanding these strict regulatory prohibitions and the 75% exam passing score is critical for candidates aiming to join the 33,000 registered agents in Singapore.

The Council for Estate Agencies (CEA) mandates strict disclosure under the Code of Ethics and Professional Client Care (CEPCC). Agents must disclose any conflict of interest in writing to their clients.

• Material Facts: Agents must disclose known defects or issues that might affect the property's value or the buyer's decision.
• Dual Representation: Strictly prohibited. An agent can only represent one party (either buyer or seller) in a single transaction.
• Referral Fees: Must be disclosed to the client if the agent receives a commission from a third party (e.g., a banker or lawyer).

Failure to disclose a conflict of interest or attempting dual representation is a major violation of the Estate Agents Act and can lead to license revocation. Candidates must memorize these ethical boundaries, as Paper 2 frequently tests scenarios involving undisclosed referral fees and the mandatory disclosure of material facts during the property sales process.

To score well in the Sale of Properties section, focus on the sequence of events from the initial marketing to the final handover of keys. Familiarize yourself with the Standard Estate Agency Agreements and the HDB Resale Portal procedures.

• Practice Calculations: Ensure you can calculate BSD, ABSD, and SSD accurately under time pressure.
• Know the Acts: Land Titles Act, Planning Act, and Estate Agents Act are the primary legal pillars.
• Simulate Exams: Use the Prepare app to access over 143 practice questions specifically on Sale of Properties.

The Prepare app offers comprehensive practice questions across all 13 RES exam topics, helping you identify weak spots in your knowledge of transaction processes. Achieving the 75% passing score requires consistent practice of Paper 2 questions, focusing on the 14-day stamp duty deadline and the legal requirements of the Estate Agents Act.
