What's a CMA and How Do You Use One?

A CMA stands for Comparative Market Analysis, and it is the single most important tool an agent uses to determine what your home is worth in today's market. Think of it as a custom-built price estimate backed by real data, not an algorithm.

Every seller wants to know the same thing: "What will my home sell for?" The answer is not just a number you pull from a website. It is a carefully researched range based on what similar homes have actually sold for, what is currently for sale, and what did not sell. That is the essence of a CMA.

What a CMA Includes

A complete CMA draws on three categories of data from the local Multiple Listing Service (MLS). Here is what your agent should include in every CMA:

How a CMA Determines Price

A CMA is not just a list of nearby sales. It is a detailed analysis that adjusts for differences between each comparable home and your property. If your home has a renovated kitchen and the comp does not, the CMA adds value for that upgrade. If the comp has a finished basement and yours does not, the CMA subtracts accordingly.

The most common metric used is price per square foot. Your agent pulls the price per square foot from the most relevant sold comps, then applies a range based on your home's features. But price per square foot alone is not enough. A 2,000-square-foot home on a half-acre lot with a pool is worth more than the same square footage on a quarter-acre lot without one. The adjustment process accounts for all of these variables.

Market conditions also play a role. In a seller's market with low inventory, homes may sell above their comp-adjusted value. In a balanced market, the comps are the most reliable guide. Your agent's market knowledge determines how to weight these factors.

FMLS Data: The Real Source

At Team Haigh, every CMA we prepare is built on data from FMLS (First Multiple Listing Service), the primary MLS for the Atlanta metro area. FMLS gives us access to the most current and complete data on sold prices, days on market, price reductions, and listing history. This is the same data source that agents across Georgia use, and it is far more detailed than what public sites like Zillow or Redfin can access.

FMLS data includes the actual sold price (not an estimate), the terms of the sale (cash or financed, concessions paid), days on market, and price changes. This level of detail lets us build a CMA that reflects real market activity, not an algorithm's guess.

Why a CMA Is Better Than Zillow's Zestimate

Zillow's Zestimate is a convenient starting point, but it is not a pricing tool. The Zestimate is computed by an automated valuation model (AVM) that relies on public tax records, user-submitted data, and broad market trends. It does not know whether your kitchen has quartz countertops or laminate. It does not know that your street is quieter than the one three blocks over. It does not know that the home next door just sold for $50,000 over asking because it was beautifully staged.

A CMA from a real agent who has walked through your home and knows your neighborhood can factor in all of those details. In our experience, Zestimates in NW Metro Atlanta can be off by 5% to 15% in either direction, which on a $450,000 home is a difference of $22,500 to $67,500. That is too big a margin to rely on for one of the biggest financial decisions of your life.

How Often Should You Get a CMA?

If you are thinking about selling, get a CMA now even if you are not ready to list for a few months. The market can shift quickly, and knowing your home's current value helps you plan. Once you are ready to sell, your agent should prepare a fresh CMA within 30 days of listing to ensure the price is still accurate.

If your home is already on the market and not getting traction, a new CMA can reveal whether a price adjustment is needed. We recommend reviewing the CMA every 30 days during a listing to stay aligned with the market.

Team Haigh's CMA Process

When you work with Team Haigh, your CMA is not a one-size-fits-all printout. We start by visiting your home in person to see its condition, upgrades, and features firsthand. Then we pull the most relevant sold comps from FMLS, typically 5 to 10 homes within a half-mile to one-mile radius, and adjust for every meaningful difference.

We also look at the active competition. Knowing what buyers can choose from instead of your home is essential for pricing. If there are three similar homes on the market in your neighborhood, your price needs to position you competitively against all of them.

Finally, we present you with a recommended price range, not a single number. The low end represents a price that will sell quickly, and the high end represents the top of the market based on data. Where you land within that range depends on your timeline and goals. The result is a pricing strategy tailored to your situation, backed by real data and years of local market experience. Price your home with a CMA, then prep it with staging for the best results.
