In the income approach, a gross rent multiplier (GRM) of 120 means:
Correct Answer
B) The property value equals 120 times monthly rental income
A gross rent multiplier (GRM) represents the ratio of property value to monthly rental income. A GRM of 120 means the property value equals 120 times the monthly rent.
Why This Is the Correct Answer
Option B correctly defines the mathematical relationship inherent in the GRM calculation. When a property has a GRM of 120, it means that the property's total value equals exactly 120 times its monthly rental income. This is derived from the basic GRM formula: Property Value ÷ Monthly Rent = GRM, which can be rearranged to: Property Value = GRM × Monthly Rent. Therefore, a GRM of 120 literally means the property is worth 120 months (or 10 years) of rental income.
Why the Other Options Are Wrong
Option A: The property generates 120% return on investment
Option A confuses GRM with return on investment (ROI) percentage calculations. GRM is a multiplier ratio, not a percentage return, and a GRM of 120 would actually indicate a relatively low return since it means 10 years to recover the investment through rent alone.
Option C: The property has 120 rental units
Option C incorrectly interprets the GRM number as a unit count. The number 120 in GRM has nothing to do with the physical number of rental units in the property - it's purely a financial ratio multiplier.
Option D: The property appreciates 120% per year
Option D mistakes GRM for an appreciation rate percentage. GRM is a static ratio comparing current value to current rent, not a measure of how property values change over time.
The GRM Times Table
Remember 'GRM = Get Rent Multiplied' - the GRM number tells you how many TIMES the monthly rent equals the property value. Think of it like a multiplication table: if GRM is 120, then Value = 120 × Monthly Rent.
How to use: When you see a GRM question, immediately think 'multiplication' and ask yourself 'how many times the monthly rent equals the total value?' The GRM number is always the multiplier in this relationship.
Exam Tip
On exam day, if you see any GRM calculation question, write down the basic formula first: Property Value = GRM × Monthly Rent. This will help you avoid confusing GRM with percentages or other ratios.
Common Mistakes to Avoid
- -Confusing GRM with cap rates or ROI percentages
- -Thinking GRM refers to annual rent instead of monthly rent
- -Assuming higher GRM always means better investment value

Analysis
The Gross Rent Multiplier (GRM) is a fundamental valuation tool in the income approach that establishes a direct relationship between a property's market value and its gross monthly rental income. It serves as a quick comparative analysis method by expressing how many months of rent it would take to equal the property's purchase price. The GRM is calculated by dividing the property's sale price (or estimated value) by its gross monthly rental income, making it a simple ratio that investors and appraisers use for initial property evaluations. Understanding GRM is crucial because it provides a standardized way to compare similar properties in the same market area.
Background Knowledge
The Gross Rent Multiplier is one of three primary methods within the income approach to valuation, alongside direct capitalization and discounted cash flow analysis. GRM is particularly useful for quick market comparisons of similar residential income properties, though it has limitations since it doesn't account for operating expenses, vacancy rates, or other income streams.
Real-World Application
In practice, appraisers use GRM to quickly screen potential comparable sales. For example, if similar properties in an area have GRMs between 100-130, and you find a property with a GRM of 200, it might indicate the property is overpriced or has unique characteristics requiring further investigation.
