A property sold for $180,000 with a gross monthly rent of $1,800. What is the Gross Rent Multiplier (GRM)?
Correct Answer
A) 100
GRM = Sale Price ÷ Gross Monthly Rent. $180,000 ÷ $1,800 = 100.
Why This Is the Correct Answer
Option A (100) is correct because the GRM formula is Sale Price ÷ Gross Monthly Rent. Substituting the given values: $180,000 ÷ $1,800 = 100. This means it would take 100 months of gross rental income to equal the purchase price of the property. The calculation is straightforward division with no additional steps or conversions required. This GRM of 100 indicates that the property would generate gross rental income equal to its purchase price over approximately 8.33 years.
Why the Other Options Are Wrong
Option B: 8.33
Option B (8.33) incorrectly reverses the GRM formula by dividing gross monthly rent by sale price ($1,800 ÷ $180,000 = 0.01, then possibly multiplying by 100 to get 8.33). This represents the monthly rental yield as a percentage, not the Gross Rent Multiplier. While 8.33 years is how long it would take to recoup the investment, this is not what GRM measures.
Option C: 120
Option C (120) appears to be an arbitrary number that doesn't result from any standard real estate calculation using the given figures. It might represent a guess or confusion with other real estate ratios. No mathematical operation using $180,000 and $1,800 produces 120 when following proper GRM calculation methods.
Option D: 10
Option D (10) significantly underestimates the GRM and doesn't result from the correct formula application. This might come from incorrectly using annual rent instead of monthly rent, or from some other calculation error. A GRM of 10 would indicate a much more favorable investment property than what these numbers actually represent.
GPS Method
GPS = Gross rent multiplier = Price ÷ monthly rent. Remember 'GPS navigates you to the right Property investment' - just like GPS guides you somewhere, GRM guides you to good investments by showing Price divided by monthly rent.
How to use: When you see a GRM question, think 'GPS' - take the Property price (P) and divide by Gross monthly rent (G) to find your investment destination (S = solution).
Exam Tip
Always double-check that you're using monthly rent, not annual rent, in GRM calculations. Write down the formula 'GRM = Sale Price ÷ Monthly Rent' at the start of your exam to avoid formula confusion.
Common Mistakes to Avoid
- -Using annual rent instead of monthly rent in the calculation
- -Reversing the formula by dividing rent by price
- -Confusing GRM with other ratios like capitalization rate or cash-on-cash return

Analysis
The Gross Rent Multiplier (GRM) is a fundamental real estate investment metric that measures the relationship between a property's purchase price and its gross rental income. It provides a quick way to compare investment properties and assess their relative value based on income-generating potential. The GRM indicates how many months of gross rent it would take to equal the purchase price of the property. A lower GRM generally suggests a better investment opportunity, as it means the property generates more rental income relative to its cost. This metric is widely used by investors, appraisers, and real estate professionals for preliminary property analysis.
Background Knowledge
The Gross Rent Multiplier is calculated by dividing the property's sale price by its gross monthly rental income, expressed as GRM = Sale Price ÷ Gross Monthly Rent. This metric helps investors quickly compare properties and assess investment potential, with lower GRMs generally indicating better investment opportunities. GRM is different from other ratios like cap rates because it uses gross (not net) income and monthly (not annual) figures.
Real-World Application
Appraisers use GRM to quickly screen comparable sales and assess whether a property's rent-to-price ratio aligns with market standards. For example, if most properties in an area have GRMs between 90-110, a property with a GRM of 150 might be overpriced or have below-market rents.
