Screen a rental fast by comparing its price to gross annual rent. Enter both to get the GRM.
The gross rent multiplier(GRM) is a quick way to gauge how a rental property is priced relative to the rent it brings in. It compares the purchase price to the property’s gross annual rent — no expenses, no financing — so you can screen deals in seconds before doing a deeper analysis. A lower GRM means you’re paying less per dollar of rent.
GRM = Property Price ÷ Gross Annual Rent
Because it divides price by a full year of rent, GRM also reads as a rough number of years of gross rent it would take to equal the purchase price.
A property listed at $300,000 rents for $36,000 a year. GRM = $300,000 ÷ $36,000 = 8.3. Compared with similar properties, a GRM of 8.3 is mid-range. Enter your own price and rent in the calculator above to compare deals instantly.
It depends entirely on the local market. Many investors see GRMs in roughly a 4–9 range; lower is generally better for a buyer because you’re paying less for each dollar of rent. High-demand metros carry higher GRMs because buyers accept less income for appreciation potential. As always, compare against recent sales of similar properties in the same area.
GRM uses gross rent and ignores operating expenses, so it’s fast but blunt. The cap rate accounts for expenses through net operating income, so it’s more accurate for comparing properties with different cost structures. Use GRM as a first screen, then run the Cap Rate Calculator and the Rental Cash Flow Calculator on the short list.
Because GRM ignores vacancy, operating expenses, and financing, two properties with the same GRM can have very different actual returns. Treat it as a screening shortcut, not a buy decision — then dig into expenses, cash flow, and financing. When you’re ready, get matched with investor-friendly lenders.

Get MatchedThe gross rent multiplier (GRM) compares a property's price to its gross annual rent — price divided by gross annual rent. It's a fast screening metric that ignores expenses, used to compare how rentals are priced relative to the income they produce.
Divide the purchase price by the gross annual rent. For example, a $300,000 property renting for $36,000 a year has a GRM of 8.3.
It is market-dependent. Many investors see GRMs in roughly a 4 to 9 range, and lower is generally better for a buyer. Compare against similar local sales rather than a national figure.
For a buyer, lower is generally better — you pay less for each dollar of rent. A higher GRM means a higher price relative to rent, which is common in appreciation-focused markets.
GRM uses gross rent and ignores expenses; cap rate uses net operating income after expenses. GRM is faster but blunter, while cap rate is more accurate. Use GRM to screen and cap rate to compare your short list.
