Key Takeaways
- A CMA compares your home to recently sold, similar properties to estimate a realistic market value.
- The most important comparables are sold homes, not active listings, because sold prices reflect what buyers actually paid.
- Adjustments in a CMA account for differences between your home and each comparable, such as square footage or amenities.
- Days on market and price-per-square-foot are two metrics that reveal how competitive your local market is.
- A CMA is an estimate, not an appraisal — treat it as a pricing range, not a fixed number.
What a CMA Actually Is
A Comparative Market Analysis (CMA) is a document — typically prepared by a real estate agent — that estimates a property's market value by examining recent sales of similar homes nearby. It is the primary tool sellers use to set a listing price and that buyers use to assess whether an asking price is fair.
Unlike a formal appraisal conducted by a licensed appraiser, a CMA is not a legally regulated valuation. It is an informed market opinion based on available data. Understanding that distinction matters: a CMA can guide your pricing strategy, but it does not guarantee what a lender will accept or what a buyer will ultimately offer. For a deeper look at how listing prices and appraised values can diverge, see our article on why listing price and appraised value don't always match.
Most CMAs cover three categories of homes: recently sold properties, currently active listings, and expired or withdrawn listings. Each category tells a different part of the market story.
What you will need
How to Read the Comparable Sales Section
The core of any CMA is the sold comparables — homes similar to yours that have closed within roughly the past three to six months. These are the most reliable data points because they represent prices buyers actually paid, not what sellers hoped to receive.
When reviewing each comparable, look at four key attributes:
- Location: How close is the comp to your property? Ideally within the same neighborhood or school district.
- Size: Square footage should be reasonably similar — a 500-square-foot gap can meaningfully affect value.
- Condition and features: Updated kitchens, finished basements, and garage spaces all factor into price differences.
- Sale date: Markets shift. A comp from 18 months ago may not reflect today's conditions.
Your agent will apply adjustments to each comp — dollar amounts added or subtracted to account for differences between that home and yours. For example, if a comparable sold for $380,000 but had a garage your home lacks, the agent might subtract $10,000–$15,000 from that comp's adjusted value. These adjustments are estimates informed by local market data, not precise science.
Focus on Sold Homes, Not Active Listings
To understand how local inventory affects the values you see in a CMA, our guide on what inventory levels actually tell you provides useful context.
Key Metrics to Evaluate
Beyond the individual comps, a well-prepared CMA will include summary metrics that help you interpret market conditions:
- Price per square foot
- Dividing a home's sale price by its square footage creates a normalized comparison across differently sized homes. If similar homes in your area sold at $210–$230 per square foot, that range anchors your pricing conversation.
- Days on market (DOM)
- This figure shows how long comparable homes sat before going under contract. Low DOM signals strong buyer demand; high DOM suggests pricing sensitivity or lower interest. Our plain-language real estate glossary explains DOM and related terms in more detail.
- List-to-sale price ratio
- If homes in the CMA consistently sold at or above their asking price, you may have room to price toward the top of the range. If most closed below list price, the market is likely more negotiation-driven.
Active listings in the CMA show your competition — what buyers are comparing your home against right now. Understanding whether you're in a seller's or buyer's market will help you decide how aggressively to position your price.
Step-by-Step: Working Through a CMA
Use the steps below to systematically evaluate a CMA, whether you're reviewing one your agent prepared or trying to understand a draft before your listing appointment.
Identify the comparable pool
Start by reviewing which homes were selected as comparables. Confirm they are genuinely similar to your property in location, size, age, and property type. Flag any comps that seem like outliers — an unusually large or small home can skew the analysis if it's included without strong justification.
Review the adjustments for each comp
Look at what dollar amounts have been added or subtracted to normalize each comparable to your property's features. Common adjustment categories include square footage, lot size, bathroom count, garage, pool, and condition. The adjusted sale price — not the raw sale price — is what you should focus on when forming a value range.
Calculate the adjusted price-per-square-foot range
Divide each comparable's adjusted sale price by its finished square footage. List the resulting figures for all comps, then find the low end and high end. This range gives you a market-driven price-per-square-foot benchmark. Multiply that benchmark by your home's square footage to arrive at a preliminary value range.
Assess days on market for the comps
Note how long each comparable sat on the market before going under contract. If most comps sold within 10–15 days, demand is strong and pricing near the upper end of your range may be appropriate. If comps averaged 45–60 days or more, buyers have more leverage and a more conservative price may attract stronger interest.
Check the list-to-sale price ratio
For each sold comparable, compare the original asking price to the final sale price. A ratio above 100% means the home sold over asking — a sign of competitive bidding. A ratio consistently below 97% suggests buyers are successfully negotiating discounts. This context helps you decide whether to price at, above, or slightly below the top of your estimated range.
Arrive at a realistic pricing range
Synthesize your findings: the adjusted price-per-square-foot range, the DOM trend, and the list-to-sale ratio together point toward a defensible price range. Most CMAs will summarize this as a suggested list price or range. Treat the CMA as a well-informed starting point for a conversation with your agent — not a final answer — and factor in any features or conditions unique to your property that the comps may not fully capture.
Once you've worked through the CMA, discuss the suggested range with your agent before finalizing a list price. If you're preparing your home for the market, our room-by-room seller readiness checklist is a practical next step.
