What Is Gross Rent Multiplier?
The Gross Rent Multiplier (GRM) is a quick screening metric used by real estate investors to evaluate rental properties. It tells you how many years of gross rent it would take to pay for the property at its current price. Lower GRM values generally indicate better investment opportunities.
GRM is useful for initial property screening and comparison but should not be your only evaluation metric, as it does not account for operating expenses, vacancy, or financing costs.

Frequently Asked Questions
What is a good GRM?
A GRM below 10 is generally considered good for residential rental properties. In expensive markets like San Francisco or New York, GRMs of 15-25 are common, while in Midwest markets, GRMs of 5-8 are typical.
How is GRM different from cap rate?
GRM uses gross income without deducting expenses, while cap rate uses NOI (income after expenses). GRM is simpler to calculate but less precise. Cap rate provides a more accurate picture of property profitability.
Why is GRM useful if it ignores expenses?
GRM is valuable for quick comparisons between similar properties in the same market. When comparing like-for-like properties, expenses tend to be proportionally similar, making GRM a useful initial screening tool before deeper analysis.
