QUESTION 1
,A residential assessor is estimating market value for a single-family property. Several
recent sales are available, but the sales differ substantially in location, condition, and
design. Which principle should govern the selection of comparable properties?
A. Select the properties with the highest sale prices
B. Select properties requiring the fewest and most reliable adjustments
C. Select only properties within the same subdivision
D. Select the most recently constructed properties
Correct Answer: B
Explanation: The best comparables are those most similar to the subject in
characteristics that influence value and for which adjustments can be supported
reliably.
QUESTION 2
A property's current use generates less value than an alternative legally permissible
use. Under highest and best use analysis, the alternative should be considered further
only if it is also:
A. The most common use in the neighborhood
B. Physically possible and financially feasible
C. Currently used by neighboring properties
D. Eligible for a tax exemption
Correct Answer: B
Explanation: Highest and best use requires consideration of legal permissibility,
physical possibility, financial feasibility, and maximum productivity.
QUESTION 3
An assessor discovers that a comparable sale was between a parent and child at a
price substantially below market. What is the most appropriate treatment?
A. Use it because the transaction is legally recorded
B. Use it only if its price is adjusted upward by the median sale ratio
C. Exclude it if the transaction is not representative of an arm's-length market
transaction
D. Give it greater weight because it involves a known property owner
Correct Answer: C
Explanation: Non-arm's-length transactions may not reflect market behavior and
, should generally be excluded or carefully qualified.
QUESTION 4
Two neighborhoods contain nearly identical houses. Neighborhood A has
substantially superior access to employment centers. If all other factors are equal, the
assessor should generally conclude that:
A. Accessibility cannot affect residential value
B. Neighborhood A may command higher market values
C. Neighborhood B must have higher land values
D. The difference must be attributed entirely to building depreciation
Correct Answer: B
Explanation: Accessibility and location influence utility and demand and therefore
can produce measurable differences in residential market value.
QUESTION 5
A subject sold 18 months ago for $300,000. Market evidence indicates prices
increased 8% during the period. Assuming no property-specific changes, the time-
adjusted indication is closest to:
A. $308,000
B. $316,000
C. $324,000
D. $336,000
Correct Answer: C
Explanation: $300,000 × 1.08 = $324,000.
QUESTION 6
A residential property's legal description identifies a parcel substantially larger than
the area typically required for its existing improvement. The first valuation question
concerning the excess land should be:
A. Whether the excess land has independent utility or development potential
B. Whether the owner pays taxes on it
C. Whether the improvement covers at least 50% of the parcel
D. Whether neighboring properties have pools
, Correct Answer: A
Explanation: Excess land should be analyzed according to its separate utility,
potential uses, and contribution to the property's overall value.
QUESTION 7
A comparable has a superior garage relative to the subject. If the garage difference
contributes $20,000 to market value, the appropriate adjustment to the comparable is:
A. +$20,000
B. -$20,000
C. Zero
D. +$40,000
Correct Answer: B
Explanation: Because the comparable is superior, its sale price must be adjusted
downward to reflect the subject's inferior characteristic.
QUESTION 8
A valuation model consistently produces higher predicted values for expensive
properties and lower predicted values for inexpensive properties. This pattern most
strongly suggests:
A. Random error
B. Regressivity
C. Perfect calibration
D. Geographic independence
Correct Answer: B
Explanation: Regressivity occurs when lower-value properties are assessed at
relatively higher levels than higher-value properties.
QUESTION 9
Which valuation principle explains why an improvement can contribute less value
when surrounding properties are substantially inferior?
A. Substitution
B. Conformity
C. Anticipation
D. Competition
