Almost everyone starts in the same place: you type your address into a real-estate site and watch a confident number appear. It’s fun, it’s instant, and it feels authoritative. The problem comes when that number becomes the basis for a list price. In a market as varied as Indianapolis — where a beautifully renovated home and an untouched 1985 original can look identical in public records — automated estimates routinely miss by tens of thousands of dollars. The tool professionals actually use is a comparative market analysis, or CMA. This guide explains how a CMA is built, why the Zestimate and other automated estimates fall short in Indianapolis, and how both differ from a formal appraisal.
What a CMA Is
A comparative market analysis is a structured estimate of your home’s market value based on what genuinely comparable homes have recently sold for near you. The emphasis is on sold — not listed, not hoped-for, but contracted and closed. It’s the same fundamental logic a lender’s appraiser uses, applied by your agent to set a smart list price.
A good CMA doesn’t just average nearby sales. It selects homes that are truly similar — comparable square footage, bedroom and bath count, age, lot size, and location — and then makes line-item adjustments for the differences. A comparable with a finished basement yours lacks gets adjusted down; your three-car garage the comps don’t have gets adjusted up. The result is a value range grounded in your specific market, not a metro-wide guess.
How a CMA Is Built
When we prepare a CMA at Your Realty Link, the work runs through a few clear steps:
- Pull the right comps. Recent sold homes — typically the last few months — in your neighborhood or a directly comparable one, filtered to properties genuinely like yours.
- Adjust for differences. Square footage, condition, updates, garage, basement, lot, and location are each accounted for so you’re comparing apples to apples.
- Read current conditions. How fast are homes selling? A market’s days on market and the number of competing active listings tell us how aggressively to price.
- Factor in your actual home. A walkthrough (or detailed conversation) captures the updates and character that never show up in public data — the exact thing algorithms can’t see.
Why the Zestimate Misses in Indianapolis
Automated valuation models — the Zestimate and its cousins — estimate value by running public records data through a statistical model. That works better in cookie-cutter subdivisions where homes are nearly identical. It works poorly across Indianapolis, where condition and updates vary enormously from house to house and street to street.
The core weakness is simple: public data is often incomplete, lagged, or wrong. A home gut-renovated three years ago — new kitchen, baths, mechanicals — looks the same in the record as the untouched house next door. The model can’t see the granite, the new roof, or the finished basement done without a permit. It also can’t tell that the low nearby “comp” was actually an estate sale. That’s how estimates end up off by tens of thousands — and why pricing off one leads sellers to either leave money on the table or overprice and stall.
CMA vs. Appraisal vs. Zestimate
These three get blurred together, but each has a distinct job:
- Zestimate / AVM: An instant, algorithm-driven estimate from public data. Useful as a rough starting point; not reliable for pricing.
- CMA: Your agent’s human analysis of real comparable sales, adjusted for your specific home, used to set the list price. Free, and far more accurate for your property.
- Appraisal: A licensed appraiser’s formal opinion of value, ordered by the buyer’s lender to protect the loan. It uses similar comp logic but is independent and comes with a fee. Our home appraisal explainer covers this step in depth.
The smart sequence is: glance at the automated estimate for context, price off a real CMA, then present the home well so it appraises cleanly for the buyer’s lender.

“A Zestimate is a conversation starter, not a price. The number that matters is the one built from real, recent sales of homes like yours — adjusted for the things a computer can’t see from a desk.”
— Daniel Cope, Real Estate Broker, Your Realty LinkFrequently Asked Questions
Is a CMA the same as an appraisal?
No. A CMA is your agent's analysis of comparable sales used to set a list price, and it's free. An appraisal is a licensed appraiser's independent, fee-based opinion of value ordered by the buyer's lender. They use similar logic but serve different purposes.
How much does a comparative market analysis cost?
At Your Realty Link a CMA is free and comes with no obligation, whether you're planning to sell soon or simply want to understand your home's current value.
Why is the Zestimate on my home wrong?
Automated estimates rely on public records that are often incomplete or outdated. They can't see interior updates, renovation quality, or why a nearby home sold low, so in a varied market like Indianapolis they can be off by tens of thousands of dollars.
How accurate is a CMA?
A well-prepared CMA is far more accurate than an automated estimate because it uses genuinely comparable recent sales and accounts for your home's specific condition and updates. It's the same comp-based logic an appraiser uses to value your property.
