Mastering the Comparative Market Analysis: Guide for the Korea Real Estate Exam

Last updated: April 2026

For candidates preparing for the South Korea Licensed Real Estate Agent Exam (Gongin Junggaesa), mastering the principles of real estate valuation is non-negotiable. Whether you are aiming to help clients price their Gangnam apartments or evaluate commercial plots in Busan, a solid grasp of Comparative Market Analysis (CMA) is a cornerstone of your future practice. For a holistic overview of the licensing process, refer to our Complete Korea Licensed Real Estate Agent Exam Exam Guide.

In South Korea, while official certified appraisals are strictly reserved for Licensed Real Estate Appraisers (Gamjeong Pyeonggasa), licensed real estate agents must perform CMAs daily to advise buyers and sellers. Furthermore, valuation theory makes up a significant portion of the "Real Estate Principles" (부동산학개론) section of the first-tier exam. This guide breaks down the CMA frameworks, legal standards, and formulas you need to pass the exam and succeed in the Korean real estate market.

The Regulatory Framework of Valuation in South Korea

To demonstrate true expertise (EEAT) in Korean real estate, you must understand the legal foundation of property valuation. The primary legal framework governing this area is the Act on the Appraisal and Assessment of Real Estate (감정평가 및 감정평가사에 관한 법률) and the subordinate Rules on Real Estate Appraisal (감정평가에 관한 규칙).

According to these rules, the Ministry of Land, Infrastructure and Transport (MOLIT) mandates three traditional approaches to value, but the Sales Comparison Approach (거래사례비교법) is the legally preferred and most heavily tested method for residential properties, particularly the ubiquitous Korean apartment.

The Sales Comparison Approach (거래사례비교법)

The Sales Comparison Approach is the backbone of a Comparative Market Analysis. In the context of the Korean exam, candidates must know how to calculate the "Indicated Value" (비준가액) using a specific sequence of adjustments.

The Official CMA Formula

The exam frequently tests your ability to apply the following formula to arrive at the subject property's value:

Indicated Value = Comparable Sale Price × Condition Adjustment × Time Adjustment × Neighborhood Adjustment × Individual Adjustment × Area Adjustment

• Comparable Sale Price (거래사례가격): The baseline price of a recently sold, similar property.
• Condition Adjustment (사정보정): Adjustments made if the comparable was sold under abnormal conditions (e.g., a distressed family sale).
• Time Adjustment (시점수정): Adjusting for market changes between the comparable's sale date and the current valuation date.
• Neighborhood Adjustment (지역요인 비교): Used if the comparable is in a different, but competing, neighborhood.
• Individual Adjustment (개별요인 비교): Adjusting for physical differences (e.g., floor level, view, condition). In Korea, south-facing units (남향) and higher floors (로열층) command significant premiums.
• Area Adjustment (면적비교): Adjusting for differences in square meterage (usually based on exclusive use area / 전용면적).

Practical Calculation Example for the Exam

Let’s look at a typical exam scenario:

You are valuing a subject apartment in Seocho-gu. A comparable apartment in the same complex sold three months ago for 1,500,000,000 KRW. Since then, the local apartment price index has risen by 2%. The subject property is on a lower floor, making it 5% less valuable than the comparable. The areas are identical, and the comparable sale was a standard arm's-length transaction.

• Comparable Price: 1,500,000,000 KRW
• Condition Adjustment: 1.0 (No abnormal conditions)
• Time Adjustment: 1.02 (+2%)
• Neighborhood Adjustment: 1.0 (Same complex)
• Individual Adjustment: 0.95 (-5% for lower floor)
• Area Adjustment: 1.0 (Identical)

Calculation: 1,500,000,000 × 1.0 × 1.02 × 1.0 × 0.95 × 1.0 = 1,453,500,000 KRW

Data Sources for Korean CMAs

A CMA is only as good as its data. The Korean real estate market is highly transparent due to strict government reporting mandates. As an agent, you will utilize these primary systems:

1. MOLIT Actual Transaction Price System (국토교통부 실거래가 공개시스템)

Under the Real Estate Transaction Reporting Act, all property sales must be reported to the local government within 30 days of contract signing. The MOLIT system provides public access to these exact transaction prices, dates, floor levels, and construction years. This is the ultimate source of truth for your "Comparable Sale Price."

2. KB Kookmin Bank Real Estate Data (KB부동산)

For apartments, KB Real Estate provides weekly pricing indices and standard market prices (시세). Financial institutions in Korea strictly use KB standard prices to determine Loan-to-Value (LTV) ratios for mortgages. Understanding KB prices is crucial, as a CMA that drastically differs from the KB standard may result in a buyer failing to secure financing, which directly impacts contingencies in purchase agreements.

Exam Strategy: Weight of Appraisal Methods

In the Real Estate Principles section of the exam, appraisal and valuation typically account for about 15% of the total questions (usually 6 out of 40 questions). Because of the heavy mathematical component, many students struggle here. Understanding the breakdown of these questions can help you prioritize your studies.
