Understanding Comparative Market Analysis

You may have come across the term "comparative market analysis" (CMA) while exploring the real estate market, or perhaps you've received offers for a free CMA to determine your home's value. But what exactly is a comparative market analysis, and does it truly reveal your home's worth? In this article, we'll delve into the intricacies of a CMA, how it differs from an appraisal, the limitations of online valuations, and what you should look for when conducting or commissioning a CMA.

What is a Comparative Market Analysis (CMA)?

A Comparative Market Analysis is a process used in real estate to determine the value of a property by comparing it to other similar properties in terms of size, condition, location, and other relevant factors. Realtors perform CMAs to accurately price homes for sale. While it's tempting to set your home's price according to your preferences, a CMA is a vital tool to understand how your property compares to recently sold homes in your vicinity.

CMA vs. Appraisal

Although both CMAs and appraisals are used to estimate a property's value, they have notable differences. Appraisals are more specific, often done for purposes like determining a sale price or refinancing. Appraisers focus on size, bedrooms, bathrooms and make slight adjustments for location and condition. However, this may result in values that are either too high or too low. In contrast, a CMA conducted by a local real estate expert with knowledge of your area's market can be a more reliable predictor of value.

Online Valuations vs. CMA

Online valuation tools, like Zillow, offer automated estimates of a property's value. While these tools are becoming more accurate, they can't replace a CMA done by a local professional. Online tools cannot consider your home's condition, layout, and other factors that require a physical inspection. They can be fun and convenient, but relying solely on them might not yield an accurate value, making the opinion of a professional crucial.

What to Look for in a CMA

Not all CMAs are equal. To ensure you get the best price for your home, consider the following factors when conducting or reviewing a CMA:

  1. Similar Neighborhood: Examine the quality, age, and characteristics of neighboring properties. The quality of nearby homes significantly impacts your property's value. Schools and school districts should also be similar in terms of desirability.
  2. Proximity: Choose comparables that are as close to your home as possible, as they provide more accurate comparisons. Proximity to essential locations can affect a property's value.
  3. Similar Size & Configuration: Look for homes with square footage within 10% of your property's size. The number of bedrooms and bathrooms also plays a significant role in pricing.
  4. Similar Condition: The condition of a home can drastically impact its price. Homes in various conditions, from fully renovated to fixer-uppers, cater to different buyers and price points.
  5. Market Conditions: Select sales that occurred around the same time, preferably within 3-4 months. Local market conditions can change rapidly, and understanding where the market stands in relation to your comparisons is vital.
  6. Do the Math: After gathering data from neighboring homes, calculate the average pricing and adjust based on the desirability of certain amenities in your market.


A Comparative Market Analysis is a crucial step in determining your home's value in the real estate market. While conducting a CMA yourself can be worthwhile, it's often advisable to seek the expertise of a real estate professional who specializes in your area. Regardless of your approach, a well-researched CMA can save you from headaches and potentially help you secure a better selling price for your home. So, whether you're a DIY enthusiast or prefer professional assistance, make sure to leverage the power of a well-executed CMA in your real estate endeavors.
