The Gross Rent Multiplier (GRM) is Property Price ÷ Annual Gross Rent. It tells you how many years of gross rent it takes to cover the purchase price — the quickest way to screen and compare rental properties.
GRM is a screening tool, not a final analysis metric. It ignores expenses, vacancy, and financing — so it's fast but incomplete.
Use it to quickly compare similar properties in the same market. A lower GRM means higher income relative to price. Once a property passes the GRM screen, dig deeper with cap rate and cash on cash return analysis.
Quick Rule of Thumb
In most markets, a GRM under 10 is worth investigating. Under 7 is strong cash flow territory. Above 15, you're likely in an appreciation play.

What does this mean?
A GRM of 10–15 is typical in suburban or appreciating markets. Cash flow may be tighter, but you could be betting on appreciation or quality tenants with lower turnover.
