When selecting comparable sales for the sales comparison approach, which factor is MOST important?
Correct Answer
C) Sales must be arm's length transactions between unrelated parties
Why this is correct: The sales comparison approach relies on market evidence. An arm's length transaction, where buyer and seller are unrelated and act without duress, provides a price that reflects true market value. This is the foundational requirement for a valid comparable sale. Why the other choices are wrong: 'Properties must be located within 1 mile of the subject' is wrong because location parameters vary by market type and data availability. 'Properties must have identical square footage' is wrong because exact similarity is rare; adjustments are made for differences. 'Sales must have occurred within the past 6 months' is wrong because the relevant time frame depends on market activity and data. Exam tip: Remember the hierarchy: a valid transaction (arm's length) is essential before considering adjustments for location, time, or physical differences.

Why the Other Options Are Wrong
Option A: Properties must be located within 1 mile of the subject
While recent sales are preferred, the specific 6-month timeframe is not a rigid requirement and varies significantly by market conditions. In slow markets or unique property types, appraisers may need to go back further than 6 months to find adequate comparable sales. The key is finding sales that reflect current market conditions, which could be older sales if the market has been stable.
Option B: Properties must have identical square footage
The 1-mile radius is an arbitrary distance that doesn't account for market boundaries, neighborhood characteristics, or property types. In rural areas, comparable sales might need to come from much greater distances, while in urban areas with distinct micro-markets, sales from across the street might not be comparable. Geographic proximity is important but must be evaluated based on market area definitions rather than rigid distance rules.
Option D: Sales must have occurred within the past 6 months
Identical square footage is rarely achievable and not necessary for valid comparisons. Appraisers routinely make adjustments for size differences using market-derived data. The goal is to find reasonably similar properties and adjust for differences, not to find identical properties. Requiring identical square footage would severely limit the pool of available comparables and is not practical in real-world appraisal practice.
ARM's Length = ARM's Reach
Remember 'ARM's Length' transactions are within 'ARM's Reach' of true market value. ARM = Authentic, Reliable, Market-driven. Just like you can't reach something that's too far away, you can't reach true market value without arm's length transactions.
How to use: When you see comparable sales questions, immediately think 'Can I reach true market value?' If the transaction involves related parties, duress, or special circumstances, it's 'out of reach' for reliable market value indication.
Exam Tip
Look for the answer choice that addresses transaction integrity first, then consider physical and temporal characteristics. Remember that adjustments can be made for differences, but you cannot adjust away a fundamentally flawed transaction.
Common Mistakes to Avoid
- -Prioritizing recency over transaction integrity
- -Assuming geographic proximity automatically makes a better comparable
- -Thinking properties must be nearly identical rather than reasonably similar with adjustments
Concept Deep Dive
Analysis
The sales comparison approach relies on analyzing recent sales of similar properties to estimate the subject property's value. The fundamental principle is that these comparable sales must represent true market transactions where both buyer and seller acted freely, knowledgeably, and without undue pressure. While factors like timing, location, and property characteristics are important for making adjustments, the integrity of the transaction itself is paramount. Without arm's length transactions, the sale prices may not reflect actual market conditions, making them unreliable indicators of value regardless of how similar the properties might be.
Background Knowledge
The sales comparison approach is one of the three traditional approaches to value and relies on the principle of substitution - that a buyer will not pay more for a property than the cost of acquiring a similar substitute property. For this approach to be valid, the comparable sales must represent actual market transactions where both parties acted voluntarily and with reasonable knowledge of market conditions.
Real-World Application
In practice, appraisers must verify that sales were arm's length by researching deed records, interviewing parties when possible, and looking for red flags like sales between family members, foreclosure sales, or transactions involving unusual financing. A sale between a parent and child at below-market price, even if recent and nearby, would be rejected in favor of an older, more distant arm's length sale.
