A Comparative Market Analysis (CMA) is a report real estate agents create to estimate a home’s current market value, using data from recently sold, pending, and active properties similar in size, location, and condition to the subject property. Most agents provide a CMA at no charge. Standalone paid reports typically run $100 to $200, while a formal home appraisal costs $250 to $750.
Sellers use a CMA to set a competitive listing price without undervaluing the home or pricing it out of reach. Buyers use one to gauge fair market value before submitting an offer. The report draws on comps sold within the last 3 to 6 months, usually within a 1-mile radius of the subject property.
This guide covers what a comparative market analysis includes, how the cma vs appraisal comparison plays out, a step-by-step guide on how to run a CMA, what it costs, how accurate CMAs are, and what to do with your results once you have them.

What is a CMA in real estate?
A CMA, short for comparative market analysis, is a data-driven pricing report that a licensed real estate agent prepares to help sellers and buyers understand what a property is worth in the current market. Per the Massachusetts real estate licensing definition of CMA, a CMA analyzes comparable properties to estimate market value for a specific home. Unlike a formal home appraisal, a CMA is an informal estimate with no regulatory oversight.
What does CMA stand for?
CMA stands for Comparative Market Analysis. The full term appears in MLS systems, listing agreements, and agent communications throughout the industry. The report compares the subject property against similar nearby homes to produce a realistic price range for buying or selling.
How sellers and buyers use a CMA
For sellers, a CMA informs the initial listing price. Set it too high and the home sits; set it too low and you leave money behind. For buyers, a CMA reveals whether an asking price aligns with what comparable homes have actually sold for in the past 3 to 6 months. This home valuation tool gives both sides a data-backed starting point before any offer is made or listing goes live.
What does a CMA include?
A complete CMA covers the subject property’s physical characteristics, a set of carefully selected comps, and price adjustments that account for differences between the subject and those comps. The quality of the final home valuation depends almost entirely on those three inputs.
The property details agents evaluate
Agents record the subject property’s square footage, lot size, number of bedrooms and bathrooms, year built, overall condition, and significant upgrades such as a renovated kitchen, new roof, HVAC system, or pool. Inaccurate square footage is the most common data error in a CMA. It throws off every price-per-square-foot comparison that follows.
How agents select comparable properties
Comps in real estate analysis are recently sold properties that closely match the subject home in size, location, age, and condition. Per NAR guidelines on selecting comparable properties, agents typically use 3 to 6 comps in a standard comparative market analysis. Those comps should come from recently sold homes within the past 3 to 6 months and within a 1-mile radius of the subject property in most suburban markets. In rural areas or for unique homes with few nearby sales, agents may extend the search radius to 3 to 5 miles or expand the time window to 12 months.
The comp pool should include active listings, pending sales, and closed sales. Active listings and pending sales reflect current market conditions and buyer behavior, while closed sales provide the actual transaction prices that anchor the analysis.
Adjustments: accounting for differences
No two homes are identical, so agents adjust each comp’s sale price upward or downward to account for feature differences. If your home has a renovated kitchen and the comp does not, the agent adds value to that comp’s price to create an apples-to-apples comparison. Common adjustments range from $5,000 to $15,000 for kitchen renovations and $10,000 to $30,000 for a finished basement or pool, though the right dollar amount varies significantly by market. This adjustment process is where professional judgment enters the picture, and where two agents can produce different results from the same MLS data.
CMA vs. appraisal: what’s the difference?
The cma vs appraisal distinction starts with who prepares each report and what legal weight it carries. A CMA is an informal, data-driven estimate prepared by an agent to guide pricing and offer strategy. An appraisal is a formal, heavily regulated valuation conducted by a state-licensed appraiser that is legally required by mortgage lenders to finalize a home loan.
| Factor | CMA | Appraisal |
|---|---|---|
| Who prepares it | Licensed real estate agent | State-licensed, USPAP-certified appraiser |
| Cost | Typically free ($0); $100 to $200 if standalone | $250 to $750; national average ~$400 |
| Required by mortgage lenders? | No | Yes (legally required to finalize a home loan) |
| Regulatory oversight | None (informal estimate) | Federally regulated under USPAP standards |
| Typical turnaround | 24 to 72 hours | 1 to 2 weeks |
| Primary use | Pricing strategy and offer guidance | Loan approval and legal proceedings |
Based on Appraisal Institute and CFPB data, 2026. Verify current rates before transacting.
The Appraisal Institute licensed appraiser standards require appraisers to hold a state license and comply with Uniform Standards of Professional Appraisal Practice (USPAP), the federal regulatory framework governing appraisal methodology. Understanding the cma vs appraisal difference helps you choose the right tool: an agent’s CMA for pricing decisions, a licensed appraiser’s report for legal or lending requirements.
When do you need an appraisal vs. a CMA?
Use a CMA when you are setting a listing price, evaluating a purchase offer, or getting a general property value estimate before deciding whether to sell. Use a formal home appraisal when a mortgage lender requires it, when you are refinancing, or when the valuation will be used in a legal proceeding such as a divorce settlement or estate probate. Courts and lenders treat a USPAP-compliant home appraisal as the authoritative valuation. A CMA serves as supporting context at best in those settings.
How do I run a CMA on my property?
Knowing how to run a CMA is useful whether you are doing your own research or checking the quality of a report an agent delivers. Running one yourself is possible using public records and home-search platforms, though the result will be less precise than an agent working with full MLS data. The 6 steps below follow the same process agents use.
How to Run a Comparative Market Analysis (CMA) on Your Property
- Gather your subject property details Collect your home’s address, square footage, number of bedrooms and bathrooms, lot size, year built, overall condition, and any significant upgrades such as a renovated kitchen, new roof, HVAC system, or pool. Be precise. An incorrect square footage throws off every comparison that follows.
- Find 3 to 6 comparable sales (comps) Search recently sold homes within a 0.5-to-1-mile radius that sold within the past 3 to 6 months. Filter for properties within 10 to 20 percent of your square footage and with a similar bedroom and bathroom count. Comps in real estate searches should prioritize closed sales over active listing prices. In rural areas with few recent sales, extend the search radius to 3 miles or expand the time window to 12 months.
- Build a side-by-side comparison Create a table listing each comp’s address, sale price, square footage, price per square foot, lot size, beds and baths, year built, and key features such as a garage, pool, or renovated spaces. This side-by-side view makes differences visible before you start adjusting prices.
- Adjust comp prices for differences For every feature your home has that a comp lacks, add to that comp’s sale price. For every feature the comp has that yours does not, subtract. Common adjustments: $10,000 to $30,000 for a finished basement or in-ground pool; $5,000 to $15,000 for a renovated kitchen; $2,000 to $5,000 per 100-square-foot difference. Dollar amounts vary by market. Use local agent input for precision.
- Calculate your price range Multiply the adjusted price per square foot of your lowest comp by your home’s square footage to get the bottom of the range. Do the same with your highest comp for the top. The midpoint is your most defensible estimated value. Per CFPB guidance on how home values are estimated, a reasonable pricing range typically falls within 5 to 10 percent above and below the midpoint.
- Interpret and apply the results A CMA result is a price range, not a guaranteed sale price. If you need a fast sale, price at the lower third of the range to attract immediate offers. If you can wait for the right buyer, pricing at the upper third is reasonable in a seller’s market with tight inventory. If the range comes in below your target, re-run the analysis after 30 days or ask an agent which improvements would shift the comp set in your favor.
How much does a real estate CMA cost?
A CMA provided by a real estate agent is free in the vast majority of cases. Agents treat the free CMA as a lead-generation tool. They provide it hoping to earn your listing, which is a standard marketing practice across the industry. If you need a standalone report from an independent analyst, expect to pay $100 to $200, with some providers charging up to $300 for complex properties or specialty markets.
Free CMA vs. paid CMA: what’s the difference?
A free agent-provided CMA includes the same core elements as a paid one: subject property details, comparable sales data, price-per-square-foot adjustments, a price range recommendation, and a market trend summary. The difference is who prepared it and why. An agent providing a free CMA may present comps that support a favorable listing price to earn your business. A paid CMA from an independent analyst carries less inherent incentive to shade the numbers in any direction.
A formal home appraisal, by comparison, costs $250 to $750 with a national average near $400. That cost reflects the appraiser’s state licensing requirements and USPAP compliance obligations, neither of which applies to an agent-prepared CMA.
When agents charge for a CMA
Most agents will not charge for a CMA if you are considering listing your home with them in the near term. Two situations where a fee is more common: specialty or legal-purpose CMAs for divorce proceedings, estate settlements, or investor analysis; and requests from sellers who are clearly not planning to list soon. In those cases, $100 to $200 is the typical range. Bureau of Labor Statistics data on real estate agent services shows that free market analysis is a standard part of a listing agent’s service package, not a separately billed item.
Will a Realtor do a CMA for free?
Yes, most Realtors provide a CMA for free as a standard part of their services when you are considering listing your home. The free CMA does not commit you to listing with that agent. It is a common marketing practice agents use to begin a business relationship.
What you get when you request a free CMA
A standard free CMA typically includes: a summary of your subject property’s details, a comp set of 3 to 6 recently sold homes, price-per-square-foot comparisons, price adjustments for feature differences, a recommended listing price range, and a brief market summary showing whether current market conditions reflect a seller’s market or buyer’s market. Automated tools like a Zestimate are not CMAs. They are algorithmic property value estimates without agent judgment or MLS data verification.
How to request a CMA from an agent
Contact two or three local agents, describe your property, and ask specifically for a comparative market analysis. Most will schedule a brief walkthrough of your home to verify condition and upgrades before finalizing the report. If you are not ready to list immediately, be upfront about your timeline. Some agents may decline or charge a small fee if a listing is more than 6 to 12 months away.
Are CMAs always accurate?
CMAs are generally reliable in stable markets but can miss by 10 to 20 percent or more when market conditions shift rapidly or comparable sales are scarce. The accuracy of any home valuation from a CMA depends on the quality and recency of the comp set the agent selects.
Factors that can skew a CMA
Two agents running a CMA on the same property may produce different results because comp selection and price adjustments involve professional judgment, not a fixed formula. Common accuracy issues include: comps older than 6 months that no longer reflect current pricing; comps more than 2 miles away in a suburban market where neighborhood values vary significantly; price adjustments that ignore major condition differences; and ranges built from active listing prices rather than closed sale prices. Active listings represent what sellers are asking, not what buyers are paying. Relying on them inflates the property value estimate.
The accuracy of a CMA also drops for unique or rural properties where few comparable homes exist. When only one or two comps are available, the price range widens significantly and carries less confidence.
CMA accuracy in fast-moving markets
In a fast-moving market where prices are rising or falling more than 10 percent annually, a CMA can become stale within 30 to 60 days. Understanding home value market shifts at the macro level can help you recognize when a CMA may already be outdated. A sudden interest rate change or employment shift may move buyer demand before the closed sales data catches up.
The CMA validity window in stable markets is typically 30 to 90 days. If your home has been on the market for several weeks and you are reassessing your listing price, start with a new CMA rather than adjusting off an outdated one.
What to do after your CMA results
A CMA tells you what your home could sell for in the current market. What you do next depends on whether that number aligns with your goals.
If your CMA supports your target price
If the CMA range matches what you hoped to list for, your agent will typically recommend a listing price within 1 to 3 percent of the midpoint. Pricing at the midpoint attracts the broadest pool of buyers. Pricing at the upper end is reasonable in a seller’s market when inventory is tight and demand is strong. Knowing how long before selling matters here too. If you have owned for fewer than 2 years, the CMA range may not cover your acquisition costs plus selling expenses.
If your CMA comes in lower than expected
A lower-than-expected result leaves three common paths: adjust your listing price to match the market, make targeted upgrades that shift the comp set, or wait 30 days and re-run the analysis if the market is moving upward. If you list above your CMA range and the home does not attract offers, price reduction next steps deserve a hard look before you cut. A price reduction after extended time on market signals distress to buyers and typically produces a lower final sale price than starting at the CMA midpoint from day one.
Alternatives to the traditional listing path
For sellers whose CMA results reveal below-expectation value, or who need to close faster than the traditional 45-to-60-day timeline, a cash sale is a concrete alternative. Cash buyers typically offer 70 to 90 percent of fair market value. The math changes when you subtract traditional selling costs: agent commissions run 5 to 6 percent, closing costs add 1 to 3 percent, and repairs or staging can push total expenses to 8 to 10 percent of the sale price. Cash closings happen in 7 to 30 days with no repairs required and no open houses. Selling your home as-is is one path worth comparing against your CMA range before you commit to a strategy.
Your CMA tells you what your home could sell for. Cash buyers tell you what they will actually pay right now, without a listing, open houses, or agent fees. Through iBuyer.com, you can request competing offers from multiple vetted buyers and compare them against your CMA range in one place. Closings happen in 7 to 30 days. There are no repairs required and no commission deducted from your proceeds. Request your offers to see how the cash market stacks up against your agent’s estimate.

Frequently Asked Questions
CMA stands for Comparative Market Analysis, a report real estate agents use to estimate a property’s current market value. The full term appears in MLS systems, agent communications, and listing agreements. The report draws on recently sold, pending, and active properties similar to the subject home in size, location, and condition.
A CMA’s purpose is to estimate a property’s fair market value so sellers can price competitively and buyers can avoid overpaying. For sellers, the CMA informs the initial listing price. For buyers, a CMA reveals whether the asking price aligns with what comparable homes have sold for in the past 3 to 6 months.
A CMA is typically free when provided by a real estate agent; if you pay for a standalone CMA, expect to pay $100 to $200. Agents treat the free CMA as a lead-generation tool, providing it hoping to earn your listing. Specialty CMAs for legal proceedings such as divorce settlements are more likely to carry a fee; a formal appraisal costs $250 to $750, with a national average near $400.
Yes, most Realtors provide a CMA for free as part of their standard services when you are considering listing your home. The free CMA does not commit you to listing with that agent. If you are not ready to sell soon, some agents may decline or charge a small fee of $100 to $200.
To run a CMA, find 3 to 6 comparable sales from the past 3 to 6 months, then adjust comp prices for key feature differences. The most critical step is selecting strong comps that match your home in square footage (within 10 to 20 percent), bedroom count, lot size, age, and condition. See the 6-step “how to run a CMA” procedure above for the full process.
A CMA is an informal price estimate from a real estate agent; an appraisal is a regulated valuation required by mortgage lenders. The cma vs appraisal difference comes down to regulatory weight: an appraisal is federally regulated under USPAP and legally required to close a mortgage loan, while a CMA is available within 24 to 72 hours at no cost with no regulatory oversight.
Comps in real estate are recently sold properties similar to your home in size, location, and condition, used to estimate value. A reliable CMA uses comps sold within the past 3 to 6 months and within a 1-mile radius of the subject property. In rural areas or for unique properties, agents may extend the timeframe to 12 months or the radius to 3 to 5 miles.
CMAs are generally accurate in stable markets but can miss by 10 to 20 percent when market conditions shift rapidly. Two agents running CMAs on the same property may produce different results based on comp selection and price adjustments. In fast-moving markets where prices shift more than 10 percent annually, a CMA can become stale within 30 to 60 days.
A solid CMA typically uses 3 to 6 comparable properties sold within the past 3 to 6 months and within a 1-mile radius. Three is the minimum for a defensible estimate; six gives a more reliable range. Using only active listings rather than closed sale prices is a common error that inflates the estimated value.
A real estate agent can typically complete a CMA within 24 to 72 hours after gathering your property’s details and pulling MLS data. Straightforward properties in active markets often receive a CMA the same day. More complex properties with limited comps or significant upgrades may take 2 to 3 business days.
You can run a basic CMA using public records and home-search platforms, but the result is less precise than an agent’s MLS analysis. Public county tax records and major home-search sites show recent sale prices for nearby homes, which you can use to assemble a rough comp list. The gap is professional judgment on price adjustments and access to pending sales data that only agents can see.
A CMA is typically valid for 30 to 90 days; beyond that, market shifts can make the pricing guidance inaccurate. In rapidly appreciating or declining markets, 30 days can be enough to make a CMA materially outdated. If your home has been on the market and you are reassessing your price, request a new CMA before making adjustments.
A reliable CMA uses 3 to 6 recent comps within 1 mile and relies on closed sale prices, not active listing prices. Red flags in a weak CMA include comps older than 6 months, comps more than 2 miles away in a suburban market, and no adjustments for major feature differences. Ask the agent to explain which comps they selected and why before accepting the result.
A CMA can serve as informal evidence in a divorce or estate proceeding, but courts and mortgage lenders typically require a formal appraisal instead. In contested divorce cases or probate proceedings, a licensed appraiser’s USPAP-compliant report carries far more legal weight than an agent-prepared CMA. If legal proceedings are involved, consult an attorney about which valuation type is required.
