Why is a resale of the same property the strongest evidence of a market conditions trend?
Correct Answer
B) Physical and locational variables are held constant
Why this is correct: A resale of the same property (assuming no significant physical changes) holds physical and locational characteristics constant. Therefore, any price change between the two sale dates can more confidently be attributed to market conditions (time) rather than differences in the property itself. Why the other choices are wrong: The choice that resales close faster is incorrect; transaction speed is not the key factor. The choice that resale prices are always recorded more accurately is wrong; recording accuracy is not guaranteed. The choice that lenders require resale data is false; while useful, it's not a universal lender requirement. Exam tip: For isolating time adjustments, a resale is the best 'paired sale' because the property is its own control.
Why This Is the Correct Answer
A resale of the same property holds physical and locational characteristics constant between transactions, so the price change isolates the effect of market conditions.
Why the Other Options Are Wrong
Option A: Resales close faster than ordinary transactions
Speed of closing is unrelated to the analysis and provides no advantage in measuring a trend.
Option C: Resale prices are always recorded more accurately
Recording accuracy does not differ between resales and other transactions.
Option D: Lenders require resale data for trend analysis
Lender preference does not determine methodological strength. The advantage is the constancy of the property.
Same House, Different Day
Same House, Different Day. Everything else is held still, so what moved is the market.
How to use: Check each resale for renovation or deterioration between the two dates. Physical change breaks the method.
Exam Tip
Verify both transactions are arm's-length. A foreclosure or family transfer on either end contaminates the measurement.
Common Mistakes to Avoid
- -Using resales without checking for renovation
- -Including a distressed transaction on either end
- -Spanning an interval that crosses different market phases
Concept Deep Dive
Analysis
Measuring a market conditions trend means isolating the effect of time from everything else that makes properties sell for different amounts. A resale does that structurally: the same property sold twice has the same location, the same lot, the same layout and the same quality on both occasions, so the difference between the two prices is attributable to time in a way no cross-sectional comparison can match. That is why repeat sales indices are built the way they are, and why a handful of resales in the subject's own market is stronger support for a time adjustment than a much larger sample of unmatched sales. The method has known limits worth stating. Physical change between the sales — a renovation, an addition, or serious deterioration — breaks the constancy the method depends on, so each resale must be checked for it. Both transactions must be arm's-length, and the interval must be long enough to be meaningful but not so long that it spans different market phases.
Background Knowledge
Repeat sales analysis measures market conditions by comparing successive sales of the same property, holding physical and locational characteristics constant. Renovation between sales and non-arm's-length transactions undermine the method.
Real-World Application
An appraiser identifies four resales within eighteen months, confirms no renovations occurred, and derives a 4.2 percent annual trend from the price changes.
