What is Gross Rent Multiplier?
The Gross Rent Multiplier (GRM) is a quick screening tool used in real estate to compare a property’s purchase price to the rental income it generates, before accounting for expenses.
The Formula
GRM = Property Price ÷ Annual Gross Rental Income. A lower GRM generally suggests a property generates more rental income relative to its price, though it should be used alongside other metrics like cap rate and cash flow.
