GRM (Gross Rent Multiplier)

The property price divided by annual gross rent, used as a quick screening tool for investment properties.

Definition

The Gross Rent Multiplier is calculated by dividing the purchase price by the annual gross rental income. A $400,000 property generating $48,000 per year in gross rent has a GRM of 8.3. Lower GRMs suggest better value relative to rental income. GRM is a quick screening tool — it ignores expenses, vacancy, and financing, so it should not be the sole basis for investment decisions. It is most useful for comparing similar properties in the same market. Think of GRM as a first-pass filter before diving into detailed analysis with NOI and cap rate.
