A GRM of 16.7 means it would take 16.7 years of gross rent to equal the purchase price. Annual gross rent of $24,000 represents 6.0% of the property price.
What is Gross Rent Multiplier (GRM)?
GRM is a property's purchase price divided by its annual gross rental income. It tells you how many years of gross rent it would take to cover the purchase price. A $400,000 property generating $50,000 in annual rent has a GRM of 8.
GRM is a quick screening tool for comparing rental properties, not a full investment analysis. It does not account for operating expenses, vacancy, or financing costs.
Is a higher or lower GRM better?
Lower is better. A lower GRM means the property generates more income relative to its price. A GRM of 6 means the property's gross rent covers its price in 6 years, which is more attractive than a GRM of 12 where it takes twice as long.
That said, GRM should always be compared to similar properties in the same market. A GRM of 12 might be excellent in San Francisco but poor in Memphis.
What is a good GRM for a rental property?
It depends entirely on the local market. In expensive gateway cities (NYC, LA, San Francisco), GRMs of 15 to 25 are common. In major metros (Chicago, Houston, Phoenix), 8 to 14 is typical. In secondary and tertiary markets, 4 to 8 is achievable.
The most useful benchmark is the average GRM for comparable properties in the same neighborhood, not a national average.
What is the difference between GRM and cap rate?
GRM uses gross rent before expenses and is faster to calculate. Cap rate uses net operating income (after expenses) and is a more accurate measure of actual returns.
Use GRM for a quick initial screen when comparing multiple properties. Use cap rate for a detailed analysis once you have a shortlist worth investigating further.
