GRM = price $350,000 ÷ gross annual rent $24,000

Lower GRM = faster payback. A rough rule of thumb: under ~8 is often attractive in cash-flow markets, over ~12 usually signals weak rental yield. GRM ignores expenses and financing, pair it with cap rate and cash-on-cash.

The GRM formula

GRM = Property Price ÷ Gross Annual Rent

GRM is the simplest rent-to-price screen. A GRM of 10 means the price equals 10 years of gross rent. Because it ignores expenses and financing, treat it as a first filter, then run the cap rate and cash-on-cash math.

GRM and the 1% rule are cousins. At a 1% monthly rent-to-price ratio, annual rent is 12% of price, so GRM equals 1 ÷ 0.12, which is about 8.33. Both describe the same rent-to-price relationship from different angles. See the 1% rule →

GRM across the markets we track

Here is the gross rent multiplier for each of the 18 metros in the Investor Yield Index, using live Zillow price and rent figures. Only 12 of 18 sit under the ~12 line that usually marks a healthy screen, and only the cheapest clear the under-8 mark. That is the rate environment talking, not a flaw in these cities. The numbers below are live Zillow figures for illustration, not lender quotes.

Common questions about GRM

How is GRM calculated?

GRM = property price ÷ gross annual rent. It tells you how many years of gross rent it takes to recoup the price (before expenses).

What is a good GRM?

Lower is better. Under about 8 is often attractive in cash-flow markets, and over about 12 usually signals weak rental yield. GRM ignores expenses, so confirm with cap rate before you commit.

How does GRM differ from cap rate?

GRM uses gross rent with no expenses and is a fast screen. Cap rate uses net operating income and is more complete. Use GRM to shortlist, then cap rate to decide.
