What Is a Good Gross Rent Multiplier?
A good GRM is useful only in context. Compare similar properties in the same market, then review expenses, vacancy, and financing.
What is Gross Rent Multiplier?
Gross Rent Multiplier (GRM) is a property's purchase price divided by its annual gross rent. It estimates how many years of gross rent equal the purchase price. GRM does not include expenses, vacancy, taxes, or financing.
GRM = Purchase Price ÷ Annual Rent
For example, a property listed at $450,000 with a verified monthly rent estimate of $3,200 has an annual rent of $38,400. Its GRM is approximately 11.7. We use these values in our sample Rental Analysis Report.
How to read a GRM number
A lower GRM generally means a shorter repayment period through gross rent. A GRM of 8 represents 8 years of gross rent. A GRM of 15 represents 15 years. A lower GRM does not always mean a better investment. Use it as an initial comparison.
GRM ranges vary by market. Use GRM to compare properties in the same market. Do not use one GRM limit for all markets.
What counts as a good GRM?
There is no universal good GRM. Prices, rents, taxes, and expected growth differ by market. Compare the property with recent local sales and realistic rent estimates. A GRM below nearby alternatives can justify a closer look, but it does not prove positive cash flow.
What GRM doesn't tell you
GRM ignores operating expenses (property taxes, insurance, maintenance, property management, vacancy), financing costs, and appreciation. Two properties with the same GRM can have different cash flow. Complete a cash-flow analysis before you make a decision.
Where the rent number comes from
GRM depends on the rent estimate. Automated models can miss property condition, layout, or an exact location. AppraiseRent builds each estimate from comparable rentals. An experienced real estate professional reviews it before we calculate GRM.
