A comparative market analysis is the actual data behind a listing price, not a guess dressed up as one, and understanding how it’s built helps you evaluate whether a suggested price is genuinely well-supported. I’m Robbie English, REALTOR, Broker with Uncommon Realty, and here’s how it actually works.
What Goes Into Selecting Comps
A CMA starts with recently sold homes, generally within the past three to six months, that are genuinely comparable in size, age, condition, and location, ideally within the same neighborhood or a very similar one nearby. Sales older than six months get less weight, since market conditions can shift meaningfully in that window, and an agent should be able to explain why each comp was chosen, not just present a list of numbers.
Why Adjustments Matter More Than the Raw Comps
No two homes are identical, so a real CMA adjusts each comp up or down for genuine differences: an extra bedroom, a renovated kitchen, a larger lot, or a busier street. These adjustments are where real analysis happens, and where a rushed or automated estimate tends to fall short, since online valuation tools generally can’t account for condition or specific upgrades the way a human evaluation can.
Active and Pending Listings Matter Too
Sold comps tell you what buyers actually paid, but active and pending listings tell you what you’re currently competing against and where the market is heading right now. A neighborhood with several active listings similar to yours means more competition for buyer attention, which should factor into pricing even if recent solds looked strong.
What a CMA Isn’t
A CMA is not a formal appraisal, and it’s not the same as an automated online home value estimate, both of which use different methodologies and can produce meaningfully different numbers. An appraisal is a licensed, formal valuation typically ordered by a lender during a transaction; a CMA is a market-based pricing tool an agent prepares to help set a listing or offer price. Treating an online estimate as equivalent to either is a common and costly mistake.
How to Actually Use a CMA
Ask specifically why each comp was included and how it was adjusted, not just what the final suggested price is. A CMA that can’t explain its reasoning in plain terms is worth questioning, since the reasoning is what makes it more reliable than a guess.
Frequently Asked Questions
Is a CMA the same as an appraisal?
No. A CMA is a market-based pricing analysis an agent prepares, while an appraisal is a formal, licensed valuation typically ordered by a lender. They can produce different numbers since they use different methodologies.
How far back should comps go in a CMA?
Generally the past three to six months. Older sales get less weight since market conditions can shift meaningfully over a longer window.
Why do online home value estimates differ from a CMA?
Automated estimates generally can’t account for a home’s actual condition or specific upgrades the way a human evaluation of comparable sales can, which is why they often diverge from a properly prepared CMA.
If you want a real CMA prepared for your specific home rather than relying on an automated estimate, that’s worth doing before you set expectations around price.
