When a listing agent recommends a price, the serious ones back it with a comparative market analysis — a CMA. It's a side-by-side look at what similar homes near you actually sold for, adjusted for differences. It's the closest thing to how an appraiser thinks, and learning to read it turns pricing from a gut call into a defensible number.
What a CMA actually is
A CMA gathers recent sales of homes comparable to yours — the "comps" — and uses them to estimate your home's market value. Unlike an instant online estimate, which runs a broad statistical model on public data, a CMA is built by a human who can see condition, updates, and location nuances a computer can't. That's why it's far more reliable than the number on any website.
What makes a good comp
Not every nearby sale belongs in your CMA. The strongest comps are:
- Close by — same neighborhood or subdivision, ideally within a mile.
- Recent — sold in the last 3–6 months, because the market moves.
- Similar in size and layout — comparable square footage, beds, and baths.
- Similar in condition and age — a renovated home isn't a fair comp for a dated one.
- Actually closed — sold prices, not asking prices. What sellers want tells you little.
How adjustments work
No two homes are identical, so agents adjust. If a comp has an extra bathroom or a finished basement yours lacks, its price is adjusted down to compare fairly; if yours has a new roof and theirs didn't, the adjustment runs the other way. The goal is an apples-to-apples value. Reasonable people can differ on the size of an adjustment — which is exactly why the reasoning behind it matters more than the final figure.
Red flags in a CMA
- Stale comps. Sales from a year ago don't reflect today's market.
- Cherry-picked highs. An agent "buying the listing" may lean on only the top sales to win you with a big number.
- Wrong neighborhood. Comps from a nicer area across a boundary line inflate the estimate.
- Ignoring condition. Comparing your original kitchen to a remodeled one without adjusting.
Why the right price beats a high price
An inflated list price feels good for a week, then the home sits, the listing goes stale, and you end up cutting — often netting less than if you'd priced it right from day one. The first two weeks draw the most attention; a number grounded in real comps is what captures it.
Common questions
Is a CMA the same as an appraisal?
No. A CMA is an agent's pricing opinion built from comparable sales, used to set a list price. An appraisal is a licensed appraiser's formal valuation for the lender. They use similar logic, but only the appraisal governs your loan.
How is a CMA different from a Zestimate or online estimate?
An online estimate is an automated model run on public data — a rough starting range. A CMA is built by a person who can account for condition, updates, and location details a model can't see, which makes it far more accurate.
How many comps should a CMA use?
Usually a handful of strong, recent, nearby sales — quality over quantity. Three genuinely comparable homes beat ten loose matches.
