A property's gross monthly rent is $4,200. Recent sales of similar rental properties show gross rent multipliers ranging from 142 to 156. What is the indicated value range using GRM analysis?
Correct Answer
A) $596,400 to $655,200
Why this is correct: The Gross Rent Multiplier (GRM) formula is Value = Gross Monthly Rent * GRM. Using the given range: Lower value = $4,200 * 142 = $596,400. Upper value = $4,200 * 156 = $655,200. The indicated range is $596,400 to $655,200. Why the other choices are wrong: "$596,400 to $655,200 annually" mislabels the already-correct dollar amount as an annual figure; GRM based on monthly rent yields total value. "$49,700 to $54,600" results from incorrectly dividing the rent by the multiplier. "$7,156,800 to $7,862,400" results from mistakenly multiplying the annual rent ($4,200 * 12 = $50,400) by the GRM range. Exam tip: Ensure your rent period (monthly/annual) matches the GRM's basis. Monthly rent * GRM = Value.
Why This Is the Correct Answer
Option A correctly applies the GRM formula by multiplying the monthly rent ($4,200) by each end of the multiplier range (142 and 156). The calculation $4,200 × 142 = $596,400 represents the low end, while $4,200 × 156 = $655,200 represents the high end of the indicated value range. This straightforward multiplication gives the property's estimated market value range based on comparable sales data. The answer format correctly presents the range without unnecessary qualifiers.
Why the Other Options Are Wrong
Option B: $596,400 to $655,200 annually
Option B includes the word 'annually' which is incorrect and misleading. GRM analysis produces a total property value estimate, not an annual figure. The calculations are correct ($596,400 to $655,200), but adding 'annually' suggests this is an annual income or value, when it's actually the total estimated market value of the property. This terminology error makes the answer technically incorrect despite having the right numbers.
Option C: $49,700 to $54,600
Option C shows values that are far too low ($49,700 to $54,600) and appears to result from dividing the monthly rent by the GRM instead of multiplying. This represents a fundamental misunderstanding of the GRM formula. The correct formula is Property Value = Monthly Rent × GRM, not Monthly Rent ÷ GRM. This error would result in a severe undervaluation of the property.
Option D: $7,156,800 to $7,862,400
Option D shows values that are extremely high ($7,156,800 to $7,862,400) and likely results from using annual rent instead of monthly rent in the calculation. If someone incorrectly calculated annual rent as $4,200 × 12 = $50,400 and then multiplied by the GRM range, they would get inflated values. However, GRM specifically uses monthly rent, not annual rent, making this approach fundamentally incorrect.
GRM = Gross Rent × Multiplier
Remember 'GRM-MRM': Gross Rent Multiplier equals Monthly Rent Multiplied. The formula flows as: Property Value = Monthly Rent × GRM. Think of it as 'how many months of rent equals the property value.'
How to use: When you see a GRM question, immediately identify the monthly rent and the multiplier range. Set up the equation as Monthly Rent × Low GRM = Low Value, and Monthly Rent × High GRM = High Value. Always verify you're using monthly (not annual) rent.
Exam Tip
Double-check that you're multiplying (not dividing) and using monthly rent (not annual). Write out both calculations clearly: low end and high end of the range. Watch for answer choices that include incorrect terminology like 'annually' when the result should be total property value.
Common Mistakes to Avoid
- -Dividing rent by GRM instead of multiplying
- -Using annual rent instead of monthly rent
- -Confusing the final answer as an annual figure rather than total property value

Analysis
This question tests the application of Gross Rent Multiplier (GRM) analysis, a fundamental income approach method used in real estate valuation. The GRM is calculated by dividing the sale price of comparable properties by their gross monthly rental income, creating a multiplier that can be applied to the subject property's monthly rent. This method provides a quick estimate of property value based on rental income and is particularly useful for income-producing residential properties. The key is understanding that GRM uses monthly rent (not annual) and that applying a range of multipliers from comparable sales provides a value range rather than a single point estimate.
Background Knowledge
The Gross Rent Multiplier (GRM) is an income approach valuation method that relates a property's value to its gross monthly rental income. It's calculated from comparable sales by dividing the sale price by the gross monthly rent, then applied to the subject property by multiplying the subject's monthly rent by the derived GRM. This method is most reliable when comparable properties are truly similar in terms of location, size, condition, and rental characteristics.
Real-World Application
Appraisers use GRM analysis as a quick valuation check for rental properties, particularly small residential income properties. When appraising a duplex, for example, an appraiser would research recent sales of similar duplexes, calculate their GRMs, and apply the range to the subject property's rental income to estimate value. This method is often used alongside other approaches for a comprehensive valuation.
