When using paired sales analysis, the appraiser should:
Correct Answer
C) Find sales that are identical except for one characteristic
Paired sales analysis requires finding two sales that are as similar as possible except for one characteristic, allowing the appraiser to isolate the value impact of that single difference.
Why This Is the Correct Answer
Option C is correct because paired sales analysis depends on the ability to isolate the value impact of a single characteristic. When two sales are identical except for one feature (such as a pool, garage, or additional bedroom), the difference in their sale prices can be directly attributed to that one characteristic. This isolation allows the appraiser to make precise adjustments when applying the sales comparison approach. The technique would be meaningless if multiple variables were different, as it would be impossible to determine which factor caused the price difference.
Why the Other Options Are Wrong
Option A: Find sales that differ in multiple characteristics
Option A is wrong because having multiple differing characteristics defeats the purpose of paired sales analysis. When sales differ in multiple ways, it becomes impossible to isolate the value contribution of any single feature, making the analysis inconclusive and unreliable for adjustment purposes.
Option B: Use sales from different time periods
Option B is wrong because using sales from different time periods introduces market condition variables that contaminate the analysis. Time differences can reflect market appreciation or depreciation, making it impossible to isolate the impact of the specific physical characteristic being studied.
Option D: Only use sales from the same subdivision
Option D is wrong because limiting the analysis to only the same subdivision is unnecessarily restrictive and may not provide adequate data. While location similarity is important, paired sales can be effective across different but comparable neighborhoods as long as the properties are otherwise identical except for the feature being analyzed.
The PAIR Method
P - Properties must be identical, A - Analyze one difference, I - Isolate the variable, R - Reliable adjustment results. Think of a 'pair' of twins who are identical except for one feature.
How to use: When you see paired sales analysis questions, immediately think 'PAIR' and remember that like twins, the properties must be nearly identical except for one distinguishing characteristic that you're trying to value.
Exam Tip
Look for answer choices that emphasize 'one difference' or 'single characteristic' when dealing with paired sales analysis questions, and eliminate any options suggesting multiple variables or unnecessary restrictions.
Common Mistakes to Avoid
- -Trying to analyze sales with multiple differing characteristics
- -Using sales from significantly different time periods without market adjustments
- -Restricting analysis to too narrow a geographic area and missing good comparable data
Concept Deep Dive
Analysis
Paired sales analysis is a fundamental technique in the sales comparison approach that allows appraisers to quantify the value impact of specific property characteristics. The method relies on the principle of substitution and requires finding two comparable sales that are nearly identical in all respects except for one variable feature. By isolating a single difference between otherwise similar properties, the appraiser can determine how much that specific characteristic contributes to or detracts from property value. This technique is essential for making accurate adjustments when comparing the subject property to sales that differ in various features.
Background Knowledge
Paired sales analysis is based on the principle of substitution, which states that a buyer will not pay more for a property than the cost of acquiring an equally desirable substitute. The technique requires understanding of market behavior and the ability to identify truly comparable properties that differ in only one measurable characteristic.
Real-World Application
An appraiser needs to determine the value of a swimming pool. They find two recent sales in the same neighborhood: both are 3-bedroom, 2-bath ranch homes built in 1995 with similar lot sizes and conditions, but one has a pool and sold for $15,000 more. This $15,000 difference represents the pool's contributory value.
