Calculate the gross rent multiplier
The gross rent multiplier, or GRM, is a quick screening tool for rental property that compares the purchase price to the gross annual rent it produces. It is calculated by dividing the property price by the annual gross rental income. A property priced at three hundred sixty thousand that rents for thirty thousand a year has a GRM of twelve, meaning the price equals twelve years of gross rent. A lower GRM indicates a property that is cheaper relative to the rent it generates.
Unlike the cap rate, the GRM uses gross rent and ignores operating expenses, which makes it fast to calculate but less precise.
Screening with GRM
Investors use the gross rent multiplier as a first filter to compare many properties quickly before doing deeper analysis. Because it needs only the price and gross rent, it is easy to apply to a long list of listings. A lower GRM is generally more attractive, but it must be interpreted within a local market, since typical GRMs vary widely by area and property type.
The main limitation is that GRM ignores expenses, vacancy and financing, so two properties with the same GRM can have very different real returns once costs are included. Follow up promising candidates with a full cap-rate and cash-flow analysis. All calculation happens locally in your browser.

Frequently Asked Questions
What is the gross rent multiplier?
It is the property price divided by the annual gross rent, showing how many years of gross rent equal the purchase price.
Is a lower GRM better?
Generally yes, since it means the property is cheaper relative to the rent it produces, but always compare within the same local market.
How is GRM different from the cap rate?
GRM uses gross rent and ignores expenses, making it a fast screen, while the cap rate uses net operating income for a more accurate return.
What is a good GRM?
It depends heavily on the market, but many investors look for lower multipliers, often in the range of four to eight, as a starting screen.
What does GRM leave out?
It ignores operating expenses, vacancy, financing and property condition, so it is only a first filter, not a complete investment analysis.
