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.

The Gross Rent Multiplier (GRM) is a quick-and-dirty 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. 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.

GRM vs. Cap Rate: Why the Same Property Can Show Two Different Numbers

GRM and cap rate both price a property off its rent, and they can point in opposite directions on the same listing. GRM = Purchase Price ÷ Gross Annual Rents uses the top-line number and stops there; it never looks at expenses. Cap Rate = NOI ÷ Purchase Price starts from the bottom line, after every operating expense comes out.

Two buildings, same price, same GRM, different reality. Building A and Building B both list at $1,000,000 with $150,000 in gross annual rents, so both carry a GRM of 6.67. Building A runs a lean 35% expense ratio: newer roof, low vacancy, so NOI lands at $97,500 and the cap rate is 9.75%. Building B runs a 55% expense ratio: older systems, higher turnover, so NOI lands at $67,500 and the cap rate is 6.75%. GRM says these two properties are priced the same. Cap rate says Building A is the better buy by three full points.

Use GRM to screen fast, when a broker sends twenty listings and you need to cut the list to five worth a closer look before real financials exist. Use cap rate the moment a T12 lands in your inbox, because it’s the number you underwrite, negotiate on, and defend to a lender. GRM tells you where to look first. Cap rate tells you what to pay.
