Pricing a listing right is the highest-value skill you bring to a seller, and a comparative market analysis (CMA) is how you do it. A CMA is your written estimate of what a home should sell for, based on similar homes that recently sold nearby. Get it right and you win listings, price them to sell, and keep sellers confident.
Get it wrong and homes sit or leave money on the table. This guide walks through the agent’s real workflow: pick comps, adjust in dollars, set a defensible range, and defend it. You’ll also get a worked example with the math and a repeatable checklist.
It’s a skill you first learn in a real estate license course and see again on the licensing exam.

Key Takeaways
- A CMA is an agent’s opinion of a home’s value, drawn from recently sold comparable properties. It’s an estimate, not a formal valuation.
- Comps are 3 to 6 similar homes that sold recently and close by. You pull them from the MLS, your primary sales database.
- Adjustments turn feature differences into dollars, so every comp is compared on equal footing.
- The output is a price range you can defend, not a single guessed number.
- A CMA is not an appraisal. Appraisals are done by licensed appraisers and carry lender and legal weight.
- Free online estimates are a starting point, not a substitute for an agent’s local knowledge and MLS access.
What Is a Comparative Market Analysis (CMA)?
A comparative market analysis is the report an agent builds to estimate a home’s likely sale price. You base it on comps, meaning comparable properties: similar homes in the same area that sold recently.
The logic is simple. Buyers decide what your listing is worth by comparing it to what they could buy instead.
A CMA is an opinion of value, not a formal or legal valuation. That distinction is exactly how the comparative market analysis definition frames it: an estimate built from recently sold comparable properties. Your job is to make that opinion accurate, specific, and easy to defend.
Listing agents use a CMA to recommend a price to a seller before the home goes live. Buyer’s agents use one to advise a client on how much to offer. Same tool, two viewpoints.
In both cases, you’re answering one question: what will this home realistically sell for in the current market?
New agents often confuse a CMA with a gut-feel guess. It isn’t: it’s a documented, comp-by-comp argument. For a plain-language overview before you go deeper, see what a CMA is, then come back for the full build.
What Goes Into a CMA Report
A clean CMA has three parts: the subject property’s details, the comparable sales data, and a recommended price range. Everything else supports those three. Below is what each part covers.
CMA Section | What It Includes |
|---|---|
Subject property | Address, type, square footage, beds and baths, lot size, age, condition, and upgrades. |
Comparable sales | 3 to 6 recently sold homes with sale price, sale date, and matching features. |
Active and pending listings | Current competition that shows where the market is heading right now. |
Adjustments | Dollar changes that account for differences between each comp and the subject. |
Recommended range | A price band, plus your reasoning and a suggested list price. |
Sold comps anchor the value because they show what a buyer actually paid. Pending sales hint at where prices are moving, since the price is agreed but not closed. Active listings are asking prices, not proof, so they set the competitive ceiling rather than the value.
Weight sold data most heavily, use pending sales to sense momentum, and treat active listings as your competition. The report should end with a recommended range and a suggested list price you can explain in one sentence.
How to Do a CMA: The Agent’s 5-Step Workflow
Building a CMA is a repeatable process, not a one-off. Once you run the same five steps every time, each report gets faster and more consistent. Here’s the workflow you can use for your first listing appointment and every one after it.
Step 1: Profile the Subject Property
Start with the home you’re pricing. You can’t find good comps until you know exactly what you’re matching. Record the property type, square footage, bedrooms, bathrooms, lot size, age, and overall condition.
Note upgrades that move value, like a renovated kitchen, a finished basement, or a new roof.
Walk the home in person when you can. Photos hide deferred maintenance and oversell staging. What you see on the walk-through becomes the baseline every comp is measured against.
Action Tips
- Confirm the square footage against public records, not just the listing.
- Rate each room’s condition as updated, average, or dated.
- List every upgrade with its rough age, such as a roof replaced in 2022.
- Flag anything unusual, such as a busy road, a large lot, or a pool.
Step 2: Pull Comparable Sales From the MLS
Now find your comps. Pull them from the Multiple Listing Service (MLS), the shared database agents use to list and search sold properties. It’s your most reliable source of verified sale prices.
Aim for close matches. According to National Association of REALTORS® guidance, you generally want roughly 3 to 6 homes that sold recently and close by. Match them on size, beds, baths, and condition, then deliver a price range rather than a single number.
Favor sales from the last 90 days when you can. Stay inside the same neighborhood or school-district lines.
Keep size within about 10% of the subject and stay within one bedroom or bathroom. A crossed highway or a different school zone can change value more than distance on a map, so respect those lines.
Step 3: Adjust the Comps Feature by Feature
No two homes are identical, so you adjust. The rule is simple: add value to the comp when the subject is superior, and subtract when the comp is superior. You always adjust the comp toward the subject.
Handle size with a price-per-square-foot figure for your market. Handle discrete features (an extra bath, a garage, a renovated kitchen) with dollar amounts drawn from typical value adjustments in your area. These figures are illustrative and market-dependent: an extra bathroom might add several thousand dollars in one market and far more in another.
Add time and condition adjustments when a comp sold months ago or shows very different upkeep.
Step 4: Set the Price Range
After adjusting, you’ll have an adjusted price for each comp. Weight the closest and most recent comps most heavily, since they best reflect the subject and today’s market. Cluster the adjusted values and you’ll usually see a tight band form.
Bracket that band into a range, then set a suggested list price inside it based on the seller’s timeline and current demand. Price toward the top in a hot market and nearer the middle when inventory is rising. The range gives you room to explain your reasoning instead of defending one rigid number.
Step 5: Deliver and Defend the CMA
Presenting the CMA is where the skill pays off. Show the range, then walk the seller through the three or four comps that drove it. Tell the story: this home is like yours, here’s what sold, and here’s why you adjusted.
When a seller pushes back, point to a specific comp and the adjustment behind it rather than defending the number with conviction alone.
Expect the “but the online estimate said more” objection. Answer it with your comps and your local knowledge, not a debate about algorithms. For a deeper playbook on the pricing conversation, read how to price a home.
Comparative Market Analysis Example (Worked Walkthrough)
Here’s a fully worked example so you can see the math. The numbers below are a hypothetical for illustration only. Real adjustment amounts depend on your market, so treat these figures as a teaching model, not fixed values.
Your subject property is a 3-bed, 2-bath home with 1,800 square feet, a 2-car garage, and an updated kitchen. You pull three recent comps and adjust each one toward the subject, using an illustrative $100 per square foot for size.
Detail | Comp A | Comp B | Comp C |
|---|---|---|---|
Sold price | $410,000 | $432,000 | $398,000 |
Square footage | 1,750 | 1,900 | 1,700 |
Beds / baths | 3 / 2 | 4 / 2 | 3 / 2 |
Garage | 2-car | 2-car | 1-car |
Kitchen | Dated | Updated | Dated |
Sold | 2 months ago | 4 months ago | 5 months ago |
Now apply the adjustments. You add to a comp when the subject is superior and subtract when the comp is superior. Each dollar figure below is illustrative.
Adjustment | Comp A | Comp B | Comp C |
|---|---|---|---|
Sold price | $410,000 | $432,000 | $398,000 |
Size vs. 1,800 sq ft | +$5,000 | -$10,000 | +$10,000 |
Extra bedroom | $0 | -$10,000 | $0 |
Garage | $0 | $0 | +$7,000 |
Kitchen | +$8,000 | $0 | +$8,000 |
Adjusted value | $423,000 | $412,000 | $423,000 |
Your adjusted values land at $423,000, $412,000, and $423,000. That’s a tight cluster. Comp A is the most recent and needed the fewest changes, so you weight it most.
From this, you set a range of roughly $415,000 to $425,000 and suggest a list price near $423,000. If your seller needs a fast sale, price at the lower end. In a market with few competing listings, push toward the top.
Either way, you can point to the grid and explain every dollar.
CMA vs. Appraisal vs. BPO
New agents mix these three up constantly. All three estimate value, but they differ in who prepares them, what they cost, and how much legal weight they carry.
A BPO, or broker price opinion, is a value estimate prepared by a licensed broker or agent, usually for a bank or lender. It sits between a CMA and an appraisal.
The key line is legal weight. An appraisal is performed by a licensed appraiser under USPAP appraisal standards and carries lender and legal authority. A CMA does not.
Lenders rely on appraisals to approve a mortgage, while a CMA guides pricing and offer strategy.
Factor | CMA | BPO | Appraisal |
|---|---|---|---|
Who prepares it | Real estate agent | Licensed broker or agent | Licensed appraiser |
Typical cost to seller | Free (part of your service) | Low fee, often lender-paid | Several hundred dollars |
Legal or lender weight | None | Limited | Formal; used to approve loans |
Main use | Setting a list price or offer | Bank decisions, short sales, REO | Mortgage approval |
Typical turnaround | Hours to a day | A day or two | Days to weeks |
Use a CMA to price and win the listing. Expect a BPO when a bank needs a quick value on a distressed or bank-owned property. Know that an appraisal will confirm value once a buyer’s lender is involved.

CMA vs. Free Online Home Value Estimates
Your sellers will check a free online estimate before they ever call you. These come from an AVM, or automated valuation model, a computer program that estimates value from public and market data. It helps to understand what it can and can’t do.
Zillow’s Zestimate is a well-known example. As Zillow explains on its automated home value estimates page, the figure is built from public records, MLS data, and user-submitted details. It’s a free starting point, not a substitute for an agent’s analysis.
An AVM can’t walk the home. It doesn’t know the kitchen was gutted, the roof leaks, or the lot backs to a highway. Your CMA does, because you pull verified sold comps from the MLS and adjust for real condition.
When a seller quotes an online number, don’t argue the algorithm. Show them the comps and the adjustments behind your range.
Why CMA Skills Matter for New Agents (and on the Exam)
The CMA is a first-listing skill and a tested concept. Valuation concepts, comps, and real estate math are common topics on real estate licensing exams. So learning the CMA does double duty: it helps you prepare for the test and for the listing table.
You learn it in state-approved pre-licensing coursework, not by trial and error at your first appointment. A real estate license course gives you the structure to practice comp selection and adjustments before it counts. That’s flexibility with a clear path: you study on your own schedule, but you follow a guided sequence toward the exam and your first sale.
Colibri backs that path with support built for new agents. Our Rubi AI Tutor answers your questions the moment they come up, so a confusing adjustment doesn’t stall your studying. Our 132+ local instructors teach the market you’ll actually work in, so your comp skills match real conditions.
If you don’t pass, our Pass or Don’t Pay guarantee means you don’t pay. More than 1.5M alumni have already used this path to get licensed.

Frequently Asked Questions
Question | Answer |
|---|---|
How much does a CMA cost? | Agents almost always provide a CMA for free. It’s part of winning and serving a listing, unlike an appraisal, which the buyer usually pays for. |
How accurate is a CMA compared to an appraisal? | A well-built CMA is a strong pricing tool, but it’s an opinion of value. Only an appraisal by a licensed appraiser carries formal lender and legal weight. |
How long does it take to build a CMA? | An experienced agent can build one in a few hours once the comps are clear. Your first few will take longer, and that’s normal. |
How many comps should a CMA use? | Aim for roughly 3 to 6 closely matched sold homes, per National Association of REALTORS® guidance. Quality of the match matters more than quantity. |
Can I do my own CMA? | Sellers can try, but you’ll lack MLS access to verified sold prices. That’s why an agent’s CMA beats a free online estimate. |
Conclusion
A comparative market analysis is your argument for a price, built from evidence. Run the same five steps every time. Profile the subject, pull tight and recent comps, adjust feature by feature, set a range, then present it with the comps behind it.
The one habit that separates strong agents is discipline with comps and adjustments. Keep them recent, keep them close, and document every dollar. Do that and you can defend any price in the room.
