A property has a Gross Rent Multiplier (GRM) of 120. If the monthly rent is $3,500, what is the indicated value?
Correct Answer
B) $420,000
Why this is correct: The Gross Rent Multiplier (GRM) is calculated as Value / Monthly Gross Rent. To solve for Value, rearrange the formula: Value = Monthly Rent * GRM. Therefore, Value = $3,500 * 120 = $420,000. Why the other choices are wrong: $504,000 results from incorrectly multiplying by 144 (12 months * 120 GRM). $42,000 results from multiplying $3,500 by 12 (the GRM is already based on monthly rent). $350,000 results from using a GRM of 100. Exam tip: GRM formula: Value = Monthly Gross Rent * GRM. Ensure you're using monthly rent, not annual, unless the GRM is defined for annual rent.
Why This Is the Correct Answer
Option B ($420,000) correctly applies the GRM formula: Value = Monthly Rent × GRM. The calculation is straightforward: $3,500 (monthly rent) × 120 (GRM) = $420,000. This demonstrates proper understanding that the GRM multiplies the monthly rental income to derive an indicated property value. The formula is a direct multiplication with no additional steps or conversions required.
Why the Other Options Are Wrong
Option A: $504,000
Option A ($504,000) suggests an error in calculation, possibly multiplying by an incorrect GRM factor or adding unnecessary steps to the basic multiplication formula.
Option C: $42,000
Option C ($42,000) appears to result from dividing $3,500 by 120 instead of multiplying, which would give approximately $29.17, or some other fundamental calculation error that produces an unrealistically low property value.
Option D: $350,000
Option D ($350,000) appears to result from incorrectly dividing the monthly rent by some factor rather than multiplying by the GRM, showing a fundamental misunderstanding of the GRM formula.
GRM = Gross Rent Magic
Remember 'Gross Rent Magic' - the magic happens when you MULTIPLY monthly rent BY the GRM to get value. Think: 'Monthly rent × GRM = Market value' or use the acronym MRM: Monthly Rent × Multiplier = Market value.
How to use: When you see a GRM question, immediately identify the monthly rent and GRM, then multiply them together. Never divide - always multiply the rent BY the GRM to get the property value.
Exam Tip
Always double-check that you're multiplying (not dividing) and using monthly rent (not annual rent) when working with GRM calculations. Write out the formula before calculating to avoid errors.
Common Mistakes to Avoid
- -Dividing monthly rent by GRM instead of multiplying
- -Using annual rent instead of monthly rent in the calculation
- -Confusing GRM with other multipliers like Gross Income Multiplier (GIM)

Analysis
This question tests understanding of the Gross Rent Multiplier (GRM), a fundamental income approach tool used in real estate valuation. The GRM is a quick valuation method that relates a property's market value to its gross rental income by establishing a ratio between the two. It's calculated by dividing the property's sale price by its monthly gross rental income, and conversely, can be used to estimate value by multiplying monthly rent by the GRM. This method is particularly useful for quick property comparisons and initial value estimates in income-producing properties.
Background Knowledge
The Gross Rent Multiplier is derived from market data by analyzing the relationship between sale prices and rental income of comparable properties. It provides a quick estimation method but should be used alongside other valuation approaches for comprehensive appraisal analysis.
Real-World Application
Appraisers use GRM for quick property valuations, especially for rental properties like small apartment buildings or single-family rentals. It's particularly useful when comparing similar properties in the same market area to establish value ranges.
