How to Read a Comparative Market Analysis (CMA): What Your Agent Is Really Showing You

· Guide · 5 min read

A Comparative Market Analysis is the primary tool your real estate agent uses to recommend a list price or evaluate an offer. Most buyers and sellers receive one at the start of a transaction, glance at the final number, and move on — which means they miss the most informative part. Here is how to read a CMA in full so you can evaluate the recommendation rather than just accept it.

What a CMA is and is not

A CMA is an agent-prepared estimate of a property's market value based on recent sales of similar homes in the same area. It is not a formal appraisal and does not carry the regulatory standards or liability of a licensed appraiser's report. An agent with strong local knowledge can produce a CMA that accurately predicts the final sale price within 2–3%; an agent working outside their expertise can produce one that misses by 10–15% or more.

The key word in "comparative" is "comparable." The analysis is only as good as the comparables selected, and the selection involves real judgment calls — especially in markets with limited inventory or properties that are genuinely unusual.

The three sections of a CMA

1. Sold comparables

Sold comparables (often called "solds" or "closed sales") are the foundation of the CMA. These are properties that have transacted — a buyer and seller agreed on a price, financing closed, and the deed transferred. This is what the market actually paid, not what sellers hoped to get.

What to examine in each comparable:

2. Active listings

Active listings are the competition — what buyers can see on the market right now and compare against your home. They have not sold, which means an active listing price is not a confirmed market value, but it sets buyer expectations. A home priced above similarly active listings will face comparison pressure. A home priced below them may generate multiple offers.

3. Expired and withdrawn listings

Expired and withdrawn listings represent pricing that the market rejected. A home that was listed at $650,000 for 120 days and then withdrawn tells you that $650,000 did not work. This is useful ceiling data — if your CMA shows similar properties failed at a certain price, that price is almost certainly too high.

How adjustments work

Adjustments are the mechanism by which an agent makes unlike properties comparable. A 1,800-square-foot home is being used to estimate the value of a 2,100-square-foot home — the agent adds a value for the extra 300 square feet. A comparable with a pool is used when the subject property has no pool — the agent subtracts the pool premium.

Adjustments are estimates, not facts. A garage is worth something in most markets; what exactly it is worth per square foot is a judgment call based on what buyers have actually paid for it. Ask your agent: "How did you determine the per-square-foot adjustment?" A good agent can answer with specifics.

Common adjustment categories:

Red flags in a CMA to question

Most agents produce CMAs in good faith, but a CMA can also reflect bias. Sellers' agents who want the listing may "high-ball" the CMA to win it, then reduce the price later. Questions to ask when a CMA feels off:

For context on what a strong agent interview looks like, our guide on interviewing real estate agents includes the specific questions that reveal analytical depth versus surface-level answers.

How buyers should use a CMA

Buyers typically receive a CMA when they want to understand whether a home is fairly priced before making an offer. Two key limitations apply:

  1. The buyer's agent's CMA should be independent of the listing agent's CMA. Ask your agent to pull comparables fresh rather than working off the listing agent's analysis.
  2. In fast-moving markets, a CMA can be accurate as of two weeks ago and materially wrong today. Ask your agent: "Where has this neighborhood been tracking over the last 30 days specifically?"

For negotiation strategy once you have a CMA, our home price negotiation guide covers when the CMA supports a lower offer and how to structure concession requests. Understanding whether you are in a buyer's or seller's market also changes how much weight to give CMA comparables versus current inventory pressure; see our guide to buyer's vs. seller's markets.

When to order a professional appraisal instead

A CMA is not the right tool for every pricing decision. Consider ordering a licensed appraisal ($350–$600 for a standard residential property) before listing in these situations:

Browse real estate agents in your area at our city guides or find agents near you. When evaluating candidates, ask each one to walk you through their CMA methodology — the quality of that answer is one of the most reliable signals of analytical ability you will get before hiring.

Frequently Asked Questions

What is a CMA in real estate?
A Comparative Market Analysis (CMA) is an estimate of a home's market value based on recent sales of similar properties in the same area. It is prepared by a real estate agent (not an appraiser) and is used to help sellers price their home or help buyers understand whether an asking price is reasonable.
Is a CMA the same as an appraisal?
No. A CMA is prepared by a real estate agent and is an informal analysis used for pricing decisions. A home appraisal is conducted by a licensed appraiser under professional standards, is required by lenders for mortgage financing, and carries legal weight that a CMA does not.
How many comparables should a CMA include?
A thorough CMA typically includes 3–6 comparable sales from the last 90 days, plus 2–3 active listings and 1–2 expired listings. In fast-moving markets, agents may use 60-day windows; in slow or rural markets, 6–12 month windows are sometimes necessary due to limited transaction volume.
Can I ask my agent for a CMA before deciding to sell?
Yes, and you should. Most agents provide a free CMA as part of their listing consultation. Requesting a CMA from two or three agents before selecting one is a standard practice and gives you a range of pricing opinions and an early read on each agent's analytical rigor.
What does it mean when no good comparables exist for my home?
When a property has few close comparables — an unusual floor plan, an exceptionally large lot, a waterfront that rarely sells — the CMA relies more heavily on adjustments and the agent's judgment. In these cases, a licensed appraisal is often worth ordering before listing, since appraisers have more tools for reconciling uncommon properties.
