What Is a Comparative Market Analysis (CMA) and How Does It Help Buyers in San Diego?

What Is a CMA?

A Comparative Market Analysis (CMA) is a detailed evaluation of a property's market value based on recent sales of comparable homes in the same area. In San Diego, your buyer's agent should run a CMA for any home you are seriously considering before you make an offer — it tells you whether the asking price is fair, too high, or represents a potential bargain.

How a CMA Is Constructed

• Recent comparable sales: Homes of similar size, condition, age, and features sold in the last 60 to 90 days within a reasonable radius
• Active listings: Competing listings that establish the upper bound of what buyers are willing to pay in the current market
• Pending sales: Properties under contract that indicate where the market is heading
• Adjustments: A skilled agent adjusts for differences in square footage, lot size, condition, upgrades, views, and location between the subject property and each comparable

What the CMA Tells You

A well-constructed CMA tells you the range of likely market value for the property you are considering. This gives you three critical pieces of information: whether the asking price is supported by the market, how high you need to offer in a competitive situation to win, and what the property would appraise for — critical for managing appraisal gap risk.

CMA vs. Automated Valuation Models (AVM)

Tools like Zillow's Zestimate are Automated Valuation Models — they use algorithms to estimate value without the judgment, local knowledge, and adjustment factors that a skilled agent brings to a CMA. In San Diego's diverse and neighborhood-specific market, AVMs are often significantly off — sometimes by 5 to 15 percent or more. A professional CMA from your buyer's agent is far more reliable.
