Gross Rent Multiplier (GRM) Calculator

Lower GRM is better for investors. GRM of 6–9 is generally favorable in most markets. High-cost markets often see GRM of 15–20.

GRM ignores vacancy, operating expenses, and financing costs. It is a quick screening tool, not a full underwriting analysis.

Calculate the median GRM for your target market and compare individual properties. Below-market GRM suggests a relatively better deal.
