If you’re buying or selling a home, understanding its value can help you make a more informed decision. But how do you know whether a property is priced fairly in today’s market? A comparative market analysis (CMA) gives buyers and sellers a data-driven look at how a home compares to similar properties nearby.
In this Redfin guide, we’ll explain what a comparative market analysis is, how real estate professionals create one, and what factors can influence the results. Whether you’re preparing to list your home in Texas City, TX or evaluating a potential purchase in La Mesa, CA, understanding a CMA can help you navigate the market with greater confidence.

What is a comparative market analysis?
A comparative market analysis (CMA) is an estimate of a home’s current market value based on how it compares with similar properties in the area. Real estate agents typically prepare a CMA for sellers who are determining a listing price, but buyers can also use one to understand whether a home is competitively priced and make a more informed offer.
“A comparative market analysis is prepared by evaluating 3-5 recently sold homes, active listings, and pending sales that are similar in size, location (typically neighborhood specific), and condition to the subject property,” shares Susie Mckibben. “By adjusting for specific differences between these ‘comps’, an agent can provide a data-driven snapshot of the current local market.”
Ultimately, a CMA provides a snapshot of the local real estate market and helps buyers and sellers understand where a property may fit within that market. It can be an important starting point for making pricing, listing, or offer decisions.
How does a comparative market analysis work?
A comparative market analysis works by comparing a home with similar properties in the same local market and then adjusting the comparison based on meaningful differences. Rather than relying on a single sale or a simple average, an agent looks at several types of listings to develop a more complete picture of current market conditions.
“Many people use a CMA to estimate the value of real estate, but it’s much more than that,” states Lawrence Leung, CEO and co-founder of KeyOpp Real Estate & Property Management. “A CMA is a decision-making tool that we use to help our buyers and sellers recognize key opportunities in today’s market. A well-prepared CMA compares recently sold, active, pending and even expired listings, but layers on adjustments (higher or lower) for differences such as location, condition, size, upgrades and amenities, and market conditions.”
Identify comparable properties
The agent begins by finding homes that are reasonably similar to the property being analyzed, often prioritizing properties in the same neighborhood or a nearby area.
These may include:
Recently sold homes: Show what buyers have actually paid for comparable properties.
Active listings: Show what sellers are currently asking for similar homes and what the property may be competing against.
Pending sales: Provide insight into properties that have recently gone under contract.
Expired listings: Can offer additional context about homes that did not sell, including whether pricing or other factors may have affected their performance.
Compare the properties to the subject home
Next, the agent evaluates how each comparable property stacks up against the subject home. This can include differences in location, square footage, layout, condition, lot size, upgrades, amenities, and other features.
Make adjustments
Not every comparable home will be an exact match. An agent may adjust the analysis higher or lower depending on how a property’s features compare with the subject home.
For example, a recently sold home with a renovated kitchen and larger lot may have sold for more than a similar home without those features. These differences help an agent determine how much weight to give each comparable property when estimating the subject home’s market value.
Consider current market conditions
A CMA also takes the broader local market into account. Factors such as inventory, buyer demand, pricing trends, and the pace of sales can influence how relevant recent comparable sales are to today’s market.
Use the analysis to inform a decision
The final CMA provides a data-driven snapshot that can help a seller determine a competitive listing price or help a buyer decide how much to offer. As Lawrence notes, the purpose can extend beyond simply estimating a home’s value – it can help buyers and sellers recognize opportunities and make more confident real estate decisions.
What factors are considered in a CMA?
A comparative market analysis looks at several characteristics of a home and the surrounding market to estimate what buyers may be willing to pay. While comparable sales provide the foundation, real estate professionals may also consider a property’s location, size, condition, features, and the current balance of supply and demand.
“My CMAs not only look at recent sales, but also at the market’s trajectory,” states Laura Pallin. “Traditional CMAs often prove conservative given the unpredictable and remarkable success sellers are experiencing in today’s market. Inventory remains at historically low levels. As a result, demand is consistently driving prices beyond what traditional analysis can predict.”
When preparing a CMA, an agent may consider factors such as:
Recent comparable sales: Recently sold homes provide insight into what buyers have actually paid for similar properties.
Location: Homes in the same neighborhood or a similar market area are generally more useful comparisons than properties farther away. Location-specific factors, such as proximity to amenities or other desirable features, can also affect value.
Size and layout: Square footage, number of bedrooms and bathrooms, lot size, and the home’s overall layout can influence how it compares with other properties.
Condition: A recently renovated, move-in-ready home may command a different price than a similar property that needs significant repairs or updates.
Upgrades and amenities: Features such as a remodeled kitchen, updated bathrooms, garage, pool, outdoor living space, or other improvements can affect a home’s market value.
Age and architectural characteristics: The age, style, and overall design of a home may help determine which properties make the most appropriate comps.
Inventory: The number of similar homes currently available can provide insight into the level of competition sellers face.
Buyer demand: Strong demand can put upward pressure on prices, while weaker demand may limit how much buyers are willing to pay.
Market trajectory: An agent may look at whether prices are rising, falling, or remaining relatively stable rather than relying solely on historical sales.
Why is a CMA important for sellers?
Pricing a home is one of the most important decisions a seller makes, and a comparative market analysis can provide valuable data to help guide that decision. Rather than relying on personal expectations or what a seller paid for the home, a CMA looks at comparable properties and current market conditions to help establish a price that aligns with what buyers may actually be willing to pay.
“A comparative market analysis is one of the most important steps before selling a home because it helps homeowners understand where their property realistically stands in the current market,” recommends Ahmed Hashlamon, VP of Data at Mashvisor. “A strong CMA is not just about estimating value, it’s about understanding how buyers are likely to respond to the home today.”
A CMA can help sellers:
Set a competitive listing price: Recent comparable sales can help establish a realistic starting point for pricing the home.
Avoid overpricing: A price that’s significantly above comparable homes may discourage potential buyers and cause the property to sit on the market longer.
Understand the competition: Looking at active listings can show sellers which similar homes they’re competing against and how their property compares.
Gauge buyer demand: Pending sales, recent activity, and local market trends can provide insight into how buyers are responding to homes like theirs.
Make more confident decisions: A CMA gives sellers data they can use when determining their pricing strategy rather than relying solely on assumptions about what their home is worth.
CMA vs. home appraisal: What’s the difference?
A comparative market analysis and a home appraisal both help estimate how much a property is worth, but they are prepared for different purposes and follow different processes. A CMA is typically prepared by a real estate agent to help buyers and sellers make pricing decisions, while a home appraisal is completed by a licensed or certified appraiser and provides a formal opinion of value, often for a mortgage lender.
“A comparative market analysis and an appraisal are both tools used to estimate a property’s value. However, that’s where the similarities end; they serve very different purposes and carry different weight,” says Tony Knott. “A CMA is prepared by a real estate agent and is created by using recent sales data of comparable homes to either set a listing price or to help guide writing an offer. On the other hand, an appraisal is prepared by a licensed, independent appraiser. An appraisal is required by a lender whenever financing is involved in the purchase of real estate. This is to confirm that a property is worth what’s being financed before approving a mortgage. In short: a CMA helps in the pricing of a home, while an appraisal helps a lender verify that price is justified.”

What is a comparative market analysis: Final takeaways
A comparative market analysis can give buyers and sellers a clearer picture of how a home fits into the current real estate market. By comparing similar properties and accounting for factors like location, condition, upgrades, inventory, and demand, a CMA can help inform pricing and offer decisions. While it isn’t a formal appraisal, understanding what a comparative market analysis is can help you approach your next real estate decision with greater confidence.
