In the sales comparison approach, a comparable sale that sold 6 months ago for $350,000 requires a time adjustment of +0.5% per month. What is the adjusted sale price?
Correct Answer
A) $360,500
Time adjustment = 6 months × 0.5% = 3.0%. Adjusted price = $350,000 × 1.03 = $360,500. The positive adjustment reflects market appreciation over the 6-month period since the sale.
Why This Is the Correct Answer
The calculation requires multiplying 6 months by 0.5% per month to get a total adjustment of 3.0%. Since this is a positive adjustment reflecting market appreciation, we multiply the original price by 1.03 (adding the 3% increase). $350,000 × 1.03 = $360,500. The positive adjustment correctly accounts for the property's increased value due to market appreciation over the 6-month period.
Why the Other Options Are Wrong
Option B: $359,250
This answer of $359,250 appears to result from an incorrect calculation method, possibly applying the 0.5% monthly rate incorrectly or using simple addition rather than the proper percentage multiplication formula.
Option C: $340,750
This answer of $340,750 incorrectly applies a negative adjustment, subtracting 3% instead of adding it, which would indicate market depreciation rather than the appreciation specified by the positive adjustment rate.
Option D: $339,500
This answer of $339,500 also applies a negative adjustment but with an even larger decrease, suggesting both the wrong direction of adjustment and an incorrect calculation method.
TIME+ Formula
T.I.M.E.+ = Time period × Interest rate × Market value × Equals adjusted price (+). Remember: Positive adjustments mean 'multiply by 1.XX' where XX is the percentage increase.
How to use: When you see a time adjustment problem, identify the TIME+ components: count the months, note the monthly rate, multiply them together for total adjustment, then multiply the original price by (1 + adjustment percentage) for positive adjustments.
Exam Tip
Always double-check whether the adjustment should be positive or negative - positive adjustments use (1 + percentage) as the multiplier, while negative adjustments use (1 - percentage).
Common Mistakes to Avoid
- -Applying the adjustment in the wrong direction (subtracting instead of adding)
- -Forgetting to convert the monthly rate to a total adjustment period
- -Using simple addition/subtraction instead of percentage multiplication
Concept Deep Dive
Analysis
Time adjustments in the sales comparison approach account for market changes between the date of a comparable sale and the effective date of the appraisal. When markets are appreciating, comparable sales that occurred in the past require positive adjustments to reflect current market conditions. The adjustment is calculated by multiplying the time period by the monthly appreciation rate, then applying this percentage to the original sale price. This ensures that older sales data is brought forward to reflect what the property would likely sell for in today's market.
Background Knowledge
Time adjustments are essential in the sales comparison approach because real estate markets are dynamic and property values change over time due to economic conditions, supply and demand, and other market factors. Appraisers must adjust comparable sales to reflect market conditions as of the effective date of the appraisal, not the date when the comparable property sold.
Real-World Application
In practice, appraisers research market trends and may use MLS data, assessment records, or market studies to determine appropriate time adjustment rates, which can vary significantly based on local market conditions and property types.
