When it comes to pricing a home accurately, a Comparative Market Analysis (CMA) is a real estate agent’s secret weapon. But how many “comps” (comparable properties) do you actually need for a reliable CMA? Let’s dive in.
What is a CMA?
A Comparative Market Analysis (CMA) is an essential tool in real estate, providing an in-depth evaluation of similar, recently sold properties, often referred to as “comparables” or “comps.” This analysis helps real estate agents and homeowners determine the fair market value of a property by comparing it to other properties in the same neighborhood that have similar characteristics and have recently been sold. By analyzing these comps, a CMA provides a comprehensive understanding of the local market conditions and helps set a competitive and realistic listing price.

The Ideal Number of Comparables: It Depends!
When determining the ideal number of comparables to use in a CMA, there is no one-size-fits-all answer. The number can vary based on market conditions, neighborhood characteristics, and data availability. However, a good rule of thumb is to use at least three to five comparables. This range strikes a balance between having enough data to make an informed decision and not being overwhelmed by too much information.
Why Three to Five Comparables?
Accuracy and Reliability
Using at least three comparables helps ensure that the analysis isn’t skewed by outliers. If one comp is significantly different from the others, it can be identified and adjusted accordingly.
Market Representation
Including five comparables provides a broad view of market conditions. This range captures the diversity of recent sales, offering a more comprehensive picture of the local market.
Manageable Data
While more data can enhance accuracy, using too many comparables can make the analysis cumbersome. Limiting the number to three to five keeps the process manageable and efficient, allowing for a focused and clear comparison.
Factors Influencing the Number of Comparables
Market Activity
In a hot market with many recent sales, three to five well-matched comps may be sufficient. In a slower market, you might need to expand your search to find enough recent sales.
Neighborhood Nuances
In homogeneous neighborhoods where houses are similar in size and style, fewer comps may be needed. In diverse neighborhoods with a variety of property types, a wider range of comps is necessary to account for different property characteristics accurately.
Data Availability
In areas with limited sales data, you might need to extend your search radius or timeframe to gather enough relevant comps. This ensures the CMA is based on sufficient data to be accurate and reliable.
General Guidelines
Minimum of 3: Most real estate professionals agree that you should use at least three comparables. This provides a starting point for comparison and helps identify trends.
Ideal Range: 3-5: For most markets, using three to five well-chosen comparables is the sweet spot. This range provides a good balance between accuracy and practicality.
Maximum of 10: In some cases, you might use up to ten comparables, especially if the neighborhood is diverse or the market is slow. However, using too many comps can make it difficult to draw meaningful conclusions.
Factors to Consider When Choosing Comparables
Location
The closer the comparables are to the subject property, the better. Ideally, they should be within the same neighborhood or a similar area to account for local market conditions. Properties in the same school district or close to the same amenities are also preferable.
Property Type and Size
The comps should be similar in terms of property type (e.g., single-family home, condo) and size (square footage and lot size). This ensures that the comparison is between properties that offer similar living spaces and land.
Condition and Age
Properties that are similar in age and condition to the subject property provide more accurate comparisons. A recently renovated home might not be the best comparison for a fixer-upper, so ensure the condition of the comparables matches that of the subject property.
Sale Date
The real estate market can change rapidly. Using comparables that have sold within the last three to six months is recommended to reflect current market conditions. In a volatile market, more recent sales might be necessary to ensure accuracy.
The Importance of Adjustments
Even the best-matched comparables rarely mirror the subject property perfectly. Adjustments help refine the estimated value by compensating for variations between the subject property and its comps. Real estate agents make careful adjustments to the sales prices of the comps, considering factors such as:
Number of Bedrooms and Bathrooms
Differences in the number of bedrooms and bathrooms can significantly impact property value. Adjusting for these variations ensures a more accurate comparison.
Presence of a Garage or Pool
Features like garages, pools, and other amenities can add substantial value to a property. Adjustments account for the presence or absence of these features in the comparables.
Lot Size and Landscaping
The size of the lot and the quality of landscaping can influence property value. Larger lots or professionally landscaped properties may require upward adjustments.
Upgrades and Renovations
Recent upgrades and renovations, such as a new kitchen, bathroom remodel, or energy-efficient windows, can enhance a property’s value. Adjusting for these improvements ensures the subject property is fairly compared to its comps.
The Bottom Line
While there’s no single answer to the question of how many comparables to use for a CMA, using 3-5 well-chosen comps is a good starting point. Remember, the goal is to gather enough data to make an informed decision about pricing, while avoiding overcomplicating the process with too many variables.
