Top 5 Most Difficult RES Exam Topics in Singapore (and How to Master Them)

The Real Estate Salesperson (RES) exam is famously tough — its first-timer pass rate is reportedly under 50%. The difficulty is not spread evenly, though: a handful of dense, detail-heavy topics account for a disproportionate share of the questions candidates get wrong.

You can see the difficulty in the official 2026 syllabus itself. The toughest topics also happen to be the deepest: the property transactions unit (Paper 2, Unit 4) is the single largest block of learning outcomes in the entire course, with property finance, taxes on property, and the sale of HDB flats each carrying a long list of things you must be able to compute or advise on. Depth equals difficulty — and it is where you should spend the most preparation time.

Below are the five topics that consistently give RES candidates the most trouble, the key concepts drawn from the CEA syllabus, and a focused way to prepare for each.

1. Property Taxes & Stamp Duties

This is the topic candidates fear most, and with good reason. It spans several different taxes that each have their own incidence, timing, payer and rate — and the rates change with the cooling measures of the day. It is largely memory and calculation work, which means it is also a source of guaranteed marks once you have drilled the figures.

Key concepts to master

• Stamp duty fundamentals — the key features of the Stamp Duties Act 1929 as they apply to property.
• What is taxable, when, by whom and how much — determine the incidence, timing, payer and rate for stamp duty, property tax, income tax and GST, plus which properties are exempt.
• BSD, ABSD and SSD — decide whether a sale, purchase or sub-sale attracts Buyer's Stamp Duty, Additional Buyer's Stamp Duty and/or Seller's Stamp Duty at the prevailing rates, and compute the quantum.
• Exemptions and remissions — recognise when ABSD and/or SSD are exempted or remitted on application.
• Stamp duty on mortgages and leases/tenancies — and the computation for each.
• Property tax — the owner-occupier concession and computing tax for owner-occupied versus other properties, plus the two remission types (addition & alteration, and construction).
• Income tax & GST — when a person is deemed to be trading in property, deductible vs non-deductible rental expenses, the meaning of "taxable person/supply" and "exempt supply", and computing GST on sale, lease and agency services.

Always work from the prevailing rates — stamp duty figures are revised with each round of cooling measures.

2. Grants & Eligibility

HDB eligibility and grants are best studied together, and they are hard for one reason: the sheer number of permutations. Buyer profiles combine citizenship (SC, PR, foreigner), age, family nucleus and income ceilings — and each combination unlocks different flat types, schemes and grants. Get the profile wrong and every downstream answer falls apart.

Key concepts to master

• HDB's role & public housing policy — the key features of the Housing & Development Act 1959 (Part IV).
• Housing options — rental, new (BTO), resale, DBSS, and Executive Condominiums (from developer or open market).
• Allocation & priority schemes — for new flats, DBSS flats and ECs from the developer.
• Eligibility conditions — citizenship, age, family nucleus, income ceiling, private-property ownership and time bar, for first-timer and second-timer applicants.
• Buyer and seller eligibility — ascertain which scheme a buyer qualifies for, and whether a seller is eligible to sell in the open market.
• EIP & SPR quota — check whether the Ethnic Integration Policy and Singapore PR quota are met.
• The resale process — resale checklist, the OTP (option fee, deposit, option period, seller's cooling-off period), resale application timeframes, and HDB e-Services.
• Section 58 of the H&D Act — an HDB flat cannot be pledged as security or collateral for a debt.

3. Advertising Rules & CEA Guidelines

Property marketing in Singapore is tightly regulated, and the exam loves the detail. Questions here reward candidates who know the precise do's and don'ts across every advertising channel — and they punish guesswork.

Key concepts to master

• Code of Ethics & Professional Client Care — the salesperson's duties in respect of advertisements.
• Practice Guidelines on Ethical Advertising — the do's and don'ts for every method: flyers, pamphlets, banners, classified ads, SMS, cold calling, email, internet, roadshows, talks and seminars.
• URA, HDB and other authority guidelines — clear communication of usable vs void areas and approved use, and the prohibition of statements prejudicial to co-broking, race, religion or culture.
• Other applicable laws — Building Control (Outdoor Advertising) Regulations, URA guidelines for Central Area signs, the Singapore Code of Advertising Practice (SCAP) via ASAS, Town Council by-laws, and clearances before applying for an advertisement licence from BCA.
• PDPA & Do Not Call Registry — compliance with the Personal Data Protection Act 2012 for collecting, using and disclosing personal data in marketing.

4. Consumer Protection (Fair Trading) Act (CPFTA)

The CPFTA is a core legal topic that protects consumers against unfair practices and misrepresentation. The syllabus carries only a few learning outcomes here, but they are conceptual and scenario-based — exactly the kind that catch out candidates who memorised definitions without understanding how they apply.

Key concepts to master

• Scope — the types of real estate transactions that fall under the Act.
• Unfair practices — what actually constitutes an unfair practice in a real estate transaction.
• Consumer recourse — the remedies available to consumers, and crucially the time limit and claim limit that apply.

5. Sale of Uncompleted Private Properties

The sale of uncompleted properties is governed by detailed, procedure-heavy rules, and the exam expects you to know each stakeholder's rights and duties at every stage of the transaction. It is one of the most regulation-dense topics in Paper 2.

Key concepts to master

• Housing Developers (Control & Licensing) Act 1965 & Rules — properties covered, sale vs no-sale licence, and the duties of developers.
• Mandatory disclosures — the information a developer must give intending buyers, including scaled floor plans and the breakdown of unit floor area, plus controls on advertisements.
• Standard OTP & S&P agreement — their contents and the buyer's payment-schedule obligations.
• Transaction stages — the parties' rights and duties at OTP, S&P, Temporary Occupation Permit (TOP) and legal completion, plus the procedure for sub-sale.
• Remedies for breach — by seller or buyer, e.g. floor-area shortfall, defects, failure to deliver vacant possession, failure to pay, and unauthorised alterations.
• Sale of Commercial Properties Act 1979 — how it compares with the HDCLA, including the similarities and differences.

How to tackle the toughest topics

These five topics feel overwhelming because they reward precision: exact rates, exact eligibility rules, exact procedures. The candidates who pass on the first attempt are not the ones who read the most — they are the ones who test themselves the most. Three habits make the difference:
