Mastering Comparative Market Analysis (CMA) for the Hong Kong Estate Agent Exam

Last updated: April 2026

For aspiring real estate professionals preparing for the Estate Agents Qualifying Examination (EAQE) or the Salespersons Qualifying Examination (SQE), mastering the Comparative Market Analysis (CMA) is absolutely crucial. A CMA is the primary method estate agents use to estimate the current market value of a property by comparing it to similar, recently sold properties. In Hong Kong's fast-paced and highly regulated property market, conducting an accurate CMA requires strict adherence to Estate Agents Authority (EAA) guidelines.

This article serves as a focused guide on CMA principles specifically tailored for Hong Kong. For a broader overview of the licensing process, be sure to read our Complete Hong Kong Estate Agent Exam Exam Guide.

What is a Comparative Market Analysis (CMA)?

A Comparative Market Analysis is an evaluation of a home's value based on available local market data. Unlike a formal statutory valuation conducted by a registered surveyor (such as those from the Hong Kong Institute of Surveyors), a CMA is an informal estimate provided by an estate agent. It helps sellers set a competitive asking price and empowers buyers to make reasonable offers.

On the Hong Kong Estate Agent Exam, you will be tested not only on the mathematical calculation of property values but also on the ethical and regulatory rules governing how these estimates are presented to clients.

Key Regulatory Frameworks for CMA in Hong Kong

The Estate Agents Authority (EAA) enforces strict rules regarding property descriptions and valuations to protect consumers from misrepresentation. When studying for the exam, pay close attention to the following regulatory principles:

1. Mandatory Use of Saleable Area (SA)

Historically, Hong Kong properties were often marketed using Gross Floor Area (GFA), which included common areas like lift lobbies and staircases. However, under the EAA's Practice Circulars and the Residential Properties (First-hand Sales) Ordinance, agents must use the Saleable Area (SA) when quoting prices per square foot or square metre for residential properties. Saleable Area strictly refers to the floor area exclusively allocated to the unit, including balconies and utility platforms, but excluding bay windows and common areas. Using GFA to calculate a residential CMA is a direct violation of EAA guidelines and a common trap on the licensing exam.

2. Code of Ethics and False Misrepresentation

According to the EAA Code of Ethics, estate agents must exercise due care and due diligence when advising clients on property prices. Providing an artificially inflated CMA to secure a listing (known as "buying a listing") is considered unethical and can result in disciplinary action. Your CMA must be backed by factual, objective data.

Essential Components of a Hong Kong CMA

To construct an accurate CMA, an agent must select the right "comparables" (often called "comps"). In Hong Kong's high-density market, selecting comps requires analyzing several unique local factors.

Identifying Valid Comparables

Same Housing Estate or Building: The best comparables are units within the same housing estate (e.g., Taikoo Shing, Kingswood Villas) or the exact same building.
Floor Level: In Hong Kong, floor level drastically impacts price. Low-floor units (subject to street noise and poor views) sell for significantly less than high-floor units.
View and Orientation: A unit with a full Victoria Harbour sea view will command a massive premium over a unit in the same building facing an adjacent building's wall or a busy highway.
Time of Sale: The Hong Kong property market can fluctuate rapidly. Valid comparables should ideally be transactions registered within the last 3 to 6 months.

Sourcing Reliable Transaction Data

Exam candidates must know where agents source official data. The most authoritative source for historical property transaction records in Hong Kong is the Land Registry (accessible via the IRIS system). Agents also utilize data from the Rating and Valuation Department (RVD) and proprietary databases maintained by major agency firms.

The Impact of Property Attributes on Valuation

To illustrate how different attributes affect the price per Saleable Area square foot in a typical Hong Kong private housing estate, review the chart below. Notice how floor level creates distinct pricing tiers.

Step-by-Step CMA Calculation Example

The EAQE frequently features scenario-based questions requiring you to calculate a property's estimated value. Here is a practical example of how to adjust comparables.

Scenario: You are valuing Subject Property A: a 500 sq. ft. (Saleable Area) unit on the 15th floor (Mid-floor) with a standard city view.

Comparable 1: Sold last month. 500 sq. ft., 5th floor (Low-floor), city view. Sold for HKD 7,250,000 (HKD 14,500 / sq. ft.).
Comparable 2: Sold two months ago. 500 sq. ft., 25th floor (High-floor), city view. Sold for HKD 8,250,000 (HKD 16,500 / sq. ft.).
Comparable 3: Sold last week. 500 sq. ft., 16th floor (Mid-floor), premium sea view. Sold for HKD 8,500,000 (HKD 17,000 / sq. ft.).

Adjustment Process:

Comparable 1 is inferior (lower floor), so the subject property is worth more than HKD 7.25M. Comparable 2 is superior (higher floor), so the subject property is worth less than HKD 8.25M. Comparable 3 is on a similar floor but has a superior view, meaning the subject property is worth significantly less than HKD 8.5M.

By analyzing the gap between the low floor ($14,500/sq.ft) and high floor ($16,500/sq.ft), you can interpolate that a mid-floor unit with a standard view would be valued squarely in the middle: approximately HKD 15,500 per sq. ft.

Final Valuation: 500 sq. ft. × HKD 15,500 = HKD 7,750,000.

Common Pitfalls to Avoid on the Exam

When tackling CMA questions on the licensing exam, watch out for these common distractors:

Confusing SA and GFA: Always ensure calculations for residential properties are based on Saleable Area.
Ignoring Tenancy Status: A property sold "with tenancy" (subject to an existing lease) may have a different market value compared to a property sold with "vacant possession," especially if the rental yield is below market rate. Brush up on this concept by reading our guide on Hong Kong lease types and terms.
Overlooking Land Use Restrictions: Comparing a residential unit to a commercial or industrial unit that has been illegally converted for residential use is a critical error. Understanding these boundaries is essential; review our article on zoning and land use regulations.

Frequently Asked Questions (FAQs)

1. What is the difference between Saleable Area (SA) and Gross Floor Area (GFA) in a CMA?

Saleable Area (SA) includes the internal floor area of a unit plus balconies and utility platforms, but excludes common areas like lift lobbies and staircases. Gross Floor Area (GFA) includes a proportional share of those common areas. The EAA mandates that agents must use SA when providing price-per-square-foot metrics for residential properties to ensure transparency.

2. How recent should comparable sales be in Hong Kong?

Ideally, comparables should be from the last 3 to 6 months. In a rapidly changing market, older data may not accurately reflect current conditions. If recent data is unavailable, agents must adjust older sales data to reflect general market inflation or deflation.

3. Does selling a property "with tenancy" affect its CMA value?

Yes. A property sold with an existing tenancy means the buyer cannot move in immediately. If the existing rent is below current market rates, the property may sell at a slight discount compared to an identical unit sold with vacant possession. Conversely, a high-yield tenancy might attract investors and sustain the price.

4. Where do Hong Kong estate agents get official transaction data?

The primary official source is the Land Registry, which records all property transactions (Assignments and Sale and Purchase Agreements) in Hong Kong. Agents access this via the Integrated Registration Information System (IRIS).

5. Can an estate agent perform a statutory valuation for a mortgage?

No. Estate agents provide Comparative Market Analyses for pricing guidance. Official statutory valuations, which banks require for mortgage approvals, must be conducted by professional registered surveyors (e.g., members of the HKIS).
