What Is a Comparative Market Analysis?

In the world of real estate, making informed decisions is crucial. Whether you're selling a home, buying a property, or refinancing your mortgage, understanding the market value of a property is essential.

A CMA is a valuable tool used by real estate brokers to estimate the market value of a property based on comparable sales data.

What is a Comparative Market Analysis (CMA)?

A Comparative Market Analysis, or CMA, evaluates a property's market value. It involves analyzing recently sold properties, known as comparables, similar to the subject property in terms of location, size, condition, and features.

Real estate agents can estimate the fair market value of a property. A CMA aims to provide an accurate assessment of a property's value.

Components of a CMA

A CMA has several key components contributing to its accuracy and reliability.

  • Comparables: The first component includes a description of recently sold properties. These comparables serve as benchmarks for determining the subject property's market value. Real estate agents gather data on sold homes in the area, including information on the sold price per square foot, the number of bedrooms and bathrooms, and other relevant details.
  • Listings: Another crucial component of a CMA is information on currently listed properties. Real estate agents can gauge the competitiveness of the subject property's asking price by examining the listing prices of similar properties in the market. This information helps both buyers and sellers make informed decisions.
  • Expired properties: ACMA includes details about expired and withdrawn listings. These properties were previously on the market but did not sell. Exploring the reasons behind their lack of success can provide valuable insights into pricing strategies and market trends.

How is a CMA Conducted?

Real estate agents follow a systematic process, selecting comparables that closely resemble the subject property. These comparables should have similar property characteristics in the same neighborhood or area. They account for factors such as property size, condition, and features.

Once realtors identify the comparables, they analyze their sales data. They examine the sold price, listing price, and other relevant information. The agent can determine a fair market value for the subject property. The CMA report displays the findings clearly and concisely.

CMA vs. Appraisal

A Comparative Market Analysis (CMA) and an appraisal are both important tools used in real estate to determine a property's value, but they serve different purposes and are conducted by different professionals.

Comparative Market Analysis

A CMA is typically performed by a real estate agent. It provides a broad evaluation of a home's value based on similar properties, or "comps," that have recently been sold, are currently on the market, or were on the market but did not sell. The CMA is primarily used to help sellers price their homes competitively or help buyers determine a fair offer price.


On the other hand, an appraisal is carried out by a licensed appraiser. Lenders often require a formal and thorough evaluation to confirm a property's value before approving a mortgage loan. Appraisers use detailed criteria, including comps, and consider other aspects like the home's condition, location, and unique features.

While both CMAs and appraisals are useful, they aren't interchangeable. A CMA offers a general idea of value and can guide pricing or offers, while an appraisal provides a more definitive valuation used for lending purposes. Understanding the differences can help you make more informed decisions in your real estate transactions.

Who Conducts a CMA and Why?

Real estate agents play a crucial role in creating a CMA. They possess the expertise and knowledge to perform tasks such as

  • Gather accurate data
  • Select appropriate comparables
  • Analyze market trends.

Whether you are a seller, buyer, or someone looking to refinance a mortgage, requesting a CMA from a trusted real estate agent can provide valuable insights.


For sellers, a CMA helps determine the optimal listing price for their home. By understanding the current market conditions and the pricing of comparable properties, sellers can attract potential buyers and secure a competitive offer.


Buyers can benefit from a CMA by gauging whether a property has a fair price. By examining the CMA report, buyers can make informed decisions, negotiate effectively, and avoid overpaying for a property.

Homeowners who wish to refinance their mortgage can utilize a CMA to assess the equity in their property. This information is crucial when negotiating with lenders or determining the feasibility of a refinance.

Limitations of a CMA

While a CMA is a valuable tool, it is important to understand its limitations. A CMA is an estimate, not an appraisal. It provides a range of values based on the data available, but it does not provide an exact market value.

Various factors can affect the accuracy of a CMA, including:

  • Market conditions
  • Supply and demand changes
  • Economic fluctuations.

Unique features or improvements made to a property may not be adequately captured by comparables, potentially affecting the estimated market value.

A CMA is just one piece of the puzzle when determining a property's value is essential. A professional appraisal by a licensed appraiser may be necessary for a more precise evaluation.

A comparative market analysis (CMA) is a powerful tool used by real estate brokers to estimate the market value of a property based on comparable sales data.

It involves analyzing recently sold, currently listed, and expired or withdrawn listings. Realtors conduct to provide valuable insights for sellers, buyers, and homeowners looking to refinance. However, it is important to understand the limitations of a CMA and consider other factors when making significant real estate decisions.

If you're in the real estate market, don't underestimate the importance of a CMA. Request a CMA from a trusted real estate agent to gain valuable insights and make informed decisions.

Frequently Asked Questions About CMAs

What factors are considered in a CMA?

A CMA typically considers factors like the location, size, age, condition of the property, and the prices of similar properties that have recently sold, are currently listed or were listed but did not sell.

How often should a CMA be updated?

The real estate market can change rapidly, so if you're actively looking to buy or sell, it's a good idea to update your CMA every few months or when there are significant changes in the market.

Do I need to pay for a CMA?

Usually, real estate agents offer CMAs for free as a part of their service to potential clients. It's a way to establish a relationship and demonstrate their expertise.

How accurate is a CMA?

A CMA's accuracy can vary depending on the comparables selected and the ever-changing nature of the real estate market. It should be used as a guideline rather than a definitive valuation.

Why do different agents have different CMA results?

CMAs can vary between agents because they may select different comparables or interpret the data differently. Getting CMAs from different agents to see a range of possible values is helpful.

Can I use a CMA for refinancing my home?

While a CMA can provide a general idea of your home's value, most lenders require a formal appraisal for refinancing.

Should I use online valuation tools instead of a CMA?

Online valuation tools can be a good starting point, but they may lack the local market knowledge and nuanced understanding that a real estate professional brings to a CMA. It's often best to use these tools with a professionally prepared CMA.
