What is GRM?

Gross Rent Multiplier (GRM) is a quick screening tool that shows how many years of gross rent it would take to pay for a property. Lower GRM = potentially better deal.

GRM = Price / Annual Gross Rent

GRM Limitations

• Does not account for operating expenses
• Does not consider vacancy rates
• Should be used alongside cap rate & NOI
• Best for comparing similar properties

Frequently Asked Questions

What is Gross Rent Multiplier?

GRM is a quick screening metric that compares a property's price to its gross annual rent. It's calculated as Property Price ÷ Gross Annual Rent. Lower GRM generally indicates better cash flow potential.

What is a good GRM?

A GRM under 10 is generally considered good for cash flow markets. GRMs of 15-20+ are common in appreciation markets. Compare GRM to similar properties in the same area.

What are the limitations of GRM?

GRM doesn't account for expenses, so two properties with the same GRM could have very different NOI if expenses differ. Use GRM for initial screening, then analyze with cap rate and cash flow metrics.
