What Is a CMA in Real Estate? Comparative Market Analysis Explained
A CMA (Comparative Market Analysis) is a report that real estate agents and brokers use to estimate a property’s market value by comparing it to similar properties that have recently sold, are currently listed, or were listed but did not sell in the same area. CMAs are the primary tool agents use to help sellers set listing prices and help buyers determine fair offer prices. While a CMA is not as rigorous as a formal appraisal, it is the most practical and commonly used valuation method in residential real estate.
What Does a CMA Include?
A thorough CMA includes several components. Sold comparables (comps) are properties similar to the subject property that have sold within the last 3 to 6 months — these are the most important data points because they reflect actual market transactions. Active listings show current competition — properties the buyer could choose instead of the subject property. Expired and withdrawn listings reveal pricing mistakes — properties that did not sell because they were overpriced. Adjustments account for differences between the subject property and comparables — each bedroom, bathroom, square foot, garage space, and upgrade adds or subtracts value using a standardized adjustment grid. Finally, the agent recommends a listing price or offer range based on the analysis.
CMA vs Appraisal: Key Differences
CMAs and appraisals serve different purposes and are prepared by different people. A CMA is prepared by a real estate agent or broker for pricing guidance during listing or offer negotiation. It is free (provided as a service to clients), uses agent-selected comparables, is not regulated by any government agency, and is not accepted by lenders for mortgage approval. An appraisal is prepared by a licensed or certified appraiser, costs $400 to $800, must follow Uniform Standards of Professional Appraisal Practice (USPAP), is regulated by state appraisal boards, and is required by lenders for mortgage approval. Agents rely on CMAs for daily pricing decisions; lenders rely on appraisals for loan security.
How to Prepare a CMA
Start by selecting 3 to 6 comparable properties that sold within the last 3 to 6 months, within 0.5 to 1 mile of the subject property, with similar square footage (within 10 to 20 percent), similar bedroom and bathroom count, similar property type (single-family, condo, townhouse), and similar condition and features. Adjust the sold price of each comparable for differences — add value if the comparable has fewer features or is in worse condition, subtract value if the comparable has more features or is in better condition. Use a standard adjustment grid (most MLS platforms generate one automatically). After adjustments, calculate the average adjusted price per square foot and apply it to the subject property. Check your result against active listings — if your recommended price is far above or below current competition, revisit your adjustments.
Tools for Creating CMAs
Most real estate agents create CMAs using their local Multiple Listing Service (MLS) platform, which automatically pulls comparable data and generates adjustment grids. Third-party tools like CloudCMA, RealEstateCMA, and HouseCanary offer more sophisticated analytics with automated valuation models and market trend data. Many brokerages provide CMA templates integrated with their MLS system, reducing manual data entry. For agents preparing CMAs for listing presentations, professional presentation software like Canva or specialized CMA tools helps create polished client-facing reports.
Common CMA Mistakes to Avoid
Using comparables that are too old (more than 6 months in a changing market), too far away (more than 1 mile in urban areas), or too different in size or features. Failing to make proper adjustments — every difference between the subject and the comparable should be accounted for with a specific dollar adjustment. Cherry-picking comparables to support a desired price rather than objectively analyzing the market. Ignoring market trends — in a declining market, even good comparables from 3 months ago may overstate current value. Not verifying data — square footage, bedroom counts, and condition should be verified rather than taken from MLS listings alone.
Frequently Asked Questions
Is a CMA the same as a home appraisal?
No. A CMA is an informal market analysis prepared by a real estate agent for pricing guidance. An appraisal is a formal valuation conducted by a licensed appraiser following strict standards. Lenders require appraisals for mortgage approval but do not accept CMAs. Both use comparable sales, but appraisals follow standardized methodology and are legally regulated.
How much does a CMA cost?
CMAs are typically free. Real estate agents prepare CMAs as a service to potential clients — it is part of their marketing to win listings or represent buyers. There is no charge for a CMA, and agents typically provide one during the initial consultation before a listing agreement is signed.
Can a buyer request a CMA?
Yes. A buyer’s agent can prepare a CMA to help the buyer determine a fair offer price. The CMA shows recent sold comparables, current active listings, and market trends to support the offer strategy. Many buyer’s agents provide a CMA before writing an offer on a home.
How often should a CMA be updated?
In a normal market, a CMA should be updated every 30 days. In a fast-changing market (rapidly rising or falling prices), updates every 1 to 2 weeks are recommended. If a listing has been on the market for 30 days without an offer, a fresh CMA will often show that a price reduction is needed.
