New York Property Valuation
Practice Questions & Answers (2026)
Property valuation questions on the New York exam test the three approaches to value (sales comparison, cost, and income), how appraisals work, and what affects market value. The New York Department of State (DOS) tests when each approach is most appropriate, how adjustments are made in the sales comparison approach, and what factors an appraiser considers vs. ignores. New York candidates often struggle with income approach calculations — particularly gross rent multiplier (GRM) and net operating income (NOI) — and with the cost approach depreciation calculations. These are high-difficulty math and concept questions where careful study of the explanations pays off significantly on exam day.

Q1. The income approach to value is most appropriate for:
Explanation
The income approach is most appropriate for income-producing properties. It converts the property's net operating income into an estimate of value using a capitalization rate.
Q2. If a property has a net operating income (NOI) of $50,000 and the capitalization rate is 5%, what is the estimated value?
Explanation
Value = NOI / Cap Rate = $50,000 / 0.05 = $1,000,000. The income approach formula is Value = NOI ÷ Capitalization Rate.
Q3. Functional obsolescence refers to:
Explanation
Functional obsolescence is a loss in value resulting from outdated or poor design features within the property, such as old plumbing fixtures, an impractical floor plan, or a single bathroom in a large house.
Q4. The cost approach to value is most reliable for:
Explanation
The cost approach is most reliable for special-use properties (such as schools, churches, or government buildings) where there are few comparable sales and the income approach is not applicable.
Q5. The sales comparison approach to value requires the appraiser to find:
Explanation
The sales comparison approach requires the appraiser to identify recent sales of similar nearby properties (comparables or 'comps') and make adjustments for differences between the subject property and each comparable.
Q6. Economic obsolescence (external obsolescence) is caused by:
Explanation
Economic (external) obsolescence results from factors outside the property boundaries, such as proximity to a noisy highway, declining neighborhood conditions, or adverse zoning changes. It is typically incurable.
Q7. When using the sales comparison approach, an appraiser makes adjustments to comparables. If a comparable has a feature the subject property lacks, the appraiser will:
Explanation
If the comparable has a superior feature that the subject property lacks (e.g., an extra bathroom), the appraiser subtracts from the comparable's sale price to bring it in line with the subject property's value.
Q8. What does 'highest and best use' mean in real estate appraisal?
Explanation
Highest and best use is the reasonably probable and legal use of vacant land or an improved property that is physically possible, appropriately supported, financially feasible, and that results in the highest value.
Q9. Which appraisal method is most commonly used for single-family residential properties?
Explanation
The sales comparison approach is the most widely used and relied-upon method for appraising single-family residential properties because there are generally sufficient comparable sales available.
Q10. Assemblage refers to:
Explanation
Assemblage is the combining of two or more adjacent parcels into one larger parcel. The increased value resulting from assemblage beyond the sum of individual values is called plottage.
Q11. Effective age in appraisal refers to:
