What Is Gross Rent Multiplier (GRM)?

The Gross Rent Multiplier (GRM) is a quickanddirty valuation tool — a first filter to determine whether a property’s asking price is in the right ballpark before you do deeper analysis. Formula: GRM = Purchase Price ÷ Gross Annual Rents A property asking $2,000,000 with $280,000 in annual gross rents has a GRM of 7.14.

Formula: GRM = Purchase Price ÷ Gross Annual Rents

A property asking $2,000,000 with $280,000 in annual gross rents has a GRM of 7.14. Alternatively: Value = GRM × Annual Gross Rents.

GRM ignores expenses, vacancy, and financing. That’s both its weakness and its strength. It’s weak because two properties with identical GRMs can have completely different profitability if one has sky-high expenses. It’s strong because it’s instant — you can screen 20 listings in 10 minutes with GRM before spending hours building NOI models.

GRM benchmarks also vary by market and asset class. In a high-appreciation coastal city, multifamily GRMs of 14–18 are normal. In secondary Midwest markets, GRMs of 8–11 are common. Knowing the local GRM range tells you instantly whether a listing is priced at market, above, or below.

A practical use case: a broker sends you a 10-property blast. Three have GRMs 20% above market — skip them. Two have GRMs at market — run the NOI model. One has a GRM 15% below market — that’s your first call. GRM doesn’t close deals; it directs your attention efficiently.
