When selecting comparable sales for the sales comparison approach, which factor is MOST important?
Correct Answer
C) The degree of similarity to the subject property
While timing and location are important, the degree of similarity to the subject property is the most critical factor in selecting comparables, as it minimizes the need for adjustments and increases reliability.
Why This Is the Correct Answer
While timing and location are important, the degree of similarity to the subject property is the most critical factor in selecting comparables, as it minimizes the need for adjustments and increases reliability.
Why the Other Options Are Wrong
Option A: The sales must have occurred within the last six months
While recent sales are preferred for market relevance, the six-month timeframe is not a rigid requirement and can vary based on market conditions and data availability. In slow markets or unique property types, appraisers may need to go back further than six months to find truly comparable properties. The similarity of the property characteristics takes precedence over strict timing requirements.
Option B: The properties must be in the same subdivision
Properties don't need to be in the same subdivision to be comparable, as this requirement would be too restrictive and often impossible to meet. Comparable properties can come from different but similar neighborhoods, as long as they share similar market appeal, location desirability, and physical characteristics. The key is market similarity, not geographic boundaries.
Option D: The sales price must be within 10% of the estimated subject value
Using the estimated subject value to screen comparables creates circular reasoning and can introduce bias into the analysis. Appraisers should select comparables based on property characteristics first, then analyze the sales prices to determine value, not the other way around. This approach could eliminate valid comparables that might indicate the initial estimate was incorrect.
SIMILAR First Rule
Remember 'SIMILAR First' - Similarity comes before Time, Location, and Price when selecting comparables. Think of it as building a foundation: you need similar properties as your foundation before considering other factors.
How to use: When you see a question about selecting comparables, immediately think 'SIMILAR First' and look for the answer choice that emphasizes similarity or degree of comparability over other factors like timing, location restrictions, or price ranges.
Exam Tip
Look for answer choices that mention 'similarity,' 'comparability,' or 'degree of adjustment needed' as these typically indicate the correct answer in comparable selection questions.
Common Mistakes to Avoid
- -Focusing too heavily on recent sale dates while ignoring significant property differences
- -Limiting the search area too narrowly and missing better comparables in adjacent neighborhoods
- -Pre-screening comparables based on price expectations rather than property characteristics

Analysis
The sales comparison approach relies on the principle of substitution, which states that a rational buyer will not pay more for a property than the cost of acquiring an equally desirable substitute. The effectiveness of this approach depends heavily on finding properties that are truly comparable to the subject, requiring minimal adjustments for differences. While factors like timing, location, and price range are important considerations, they are secondary to the fundamental requirement that the comparable properties share similar physical, legal, and economic characteristics with the subject property. The more similar the comparables are to the subject, the more reliable and defensible the final value conclusion will be.
Background Knowledge
The sales comparison approach is one of the three traditional approaches to value and is based on comparing the subject property to similar properties that have recently sold in the market. The reliability of this approach depends on the appraiser's ability to find truly comparable properties and make appropriate adjustments for any differences between the comparables and the subject property.
Real-World Application
In practice, appraisers often face situations where they must choose between a very similar property that sold 8 months ago versus a less similar property that sold last month. Professional standards guide appraisers to select the more similar property and address the time difference through market condition adjustments, rather than sacrifice comparability for recency.
