Comparable Sales Research Summary
Image shows a summary view of comparable property sales research, combining a small table of individual comparable properties with aggregated statistical results used to estimate the value of a subject property.
At the top of the image is a table listing individual comparable sales. Each row represents one property and includes the following columns: A link to view the property, the property’s address, zip code, distance from the subject property, building class, sale price, date closed, and the property’s square footage. The displayed examples show three comparable properties located on 15 North 15th Street, 16 North 16th Street and 123 North 29th Street, all within the same zip code. Distances range from immediate proximity to one mile. Sale prices range from approximately $5,650,000 to $8,840,000, with sale dates in March 2025. Building square footage values are also shown for each comparable.
Below the table is a statistics panel summarizing pricing information derived from the selected comparable properties. This panel also provides the option of excluding properties based on price per square foot thresholds, allowing the user to refine which comparables are included in their metrics.
The statistical summary reports the following values:
The panel also shows the total number of properties found (13) and how many were used in the statistical calculations (11).
Additional displayed averages include:
The estimated value of the subject property is displayed at the bottom of the summary, calculated using the median price per square foot. Based on this calculation, the value of the subject property is shown to be $6,148,401.
Overall, the image communicates how selected comparable property sales are used to derive pricing statistics and estimate the value of a subject property using a median price-per-square foot methodology.
Real estate comps are crucial for all parties involved in a real estate deal: buyers, sellers, brokers, lenders, appraisers. See how real estate comps work, why they are so important, the different ways you can find comparable sales and what factors can influence them.
