A 50-unit apartment complex has had 12 units turn over in the past year. What is the turnover rate?
Correct Answer
B) 24%
Turnover rate is calculated by dividing the number of units that turned over by the total number of units: 12 ÷ 50 = 0.24 or 24%. This metric helps assess the stability and marketability of rental properties.
Why This Is the Correct Answer
Option B (24%) is correct because turnover rate is calculated using the simple formula: (Number of units turned over ÷ Total number of units) × 100. In this case, 12 units turned over out of 50 total units, so 12 ÷ 50 = 0.24 or 24%. This straightforward percentage calculation represents the proportion of the property's units that experienced tenant changes during the measurement period. The result indicates that nearly one-quarter of the apartment complex's units had tenant turnover in the past year.
Why the Other Options Are Wrong
Option A: 12%
Option A (12%) represents the raw number of units that turned over but fails to convert this to a percentage of the total units, making it an incomplete calculation that doesn't provide meaningful comparative data.
Option C: 38%
Option C (38%) appears to be a miscalculation, possibly resulting from incorrect mathematical operations or confusion with other property metrics, and doesn't follow the standard turnover rate formula.
Option D: 76%
Option D (76%) is significantly too high and likely results from inverting the calculation or applying an incorrect formula, possibly calculating 50 ÷ 12 instead of 12 ÷ 50, then converting incorrectly.
TOP Formula
Remember 'TOP' - Turnover rate = Outgoing tenants ÷ Property total units. Think of it as 'what's ON TOP' - the smaller number (units turned over) goes on top of the fraction, divided by the larger number (total units).
How to use: When you see a turnover rate question, immediately identify the two numbers: units that turned over (numerator) and total units (denominator), then apply the TOP formula and convert to percentage.
Exam Tip
Always double-check that you're dividing the smaller number (units turned over) by the larger number (total units), not the reverse, and remember to convert your decimal result to a percentage by multiplying by 100.
Common Mistakes to Avoid
- -Dividing total units by units turned over instead of the reverse
- -Forgetting to convert the decimal result to a percentage
- -Confusing turnover rate with occupancy rate or other property metrics
Concept Deep Dive
Analysis
Turnover rate is a critical metric in real estate appraisal that measures the percentage of rental units that change tenants within a specific time period, typically one year. This calculation provides valuable insight into property management effectiveness, tenant satisfaction, market conditions, and the overall stability of a rental property's income stream. A high turnover rate may indicate problems with property management, maintenance issues, or pricing concerns, while a low turnover rate suggests stable operations and satisfied tenants. Understanding turnover rates helps appraisers assess the risk profile and income stability of investment properties, which directly impacts valuation.
Background Knowledge
Turnover rate is expressed as a percentage and calculated by dividing the number of units that experienced tenant changes by the total number of units in the property. This metric is essential for evaluating rental property performance and is commonly used by appraisers, property managers, and investors to assess operational efficiency and market competitiveness.
Real-World Application
Appraisers use turnover rates to assess income property values by evaluating management quality and tenant satisfaction. A property with a 24% turnover rate like this example is moderate - not excellent but not problematic - and would be factored into vacancy assumptions and operating expense projections in the income approach to value.
