GRM (Gross Rent Multiplier)

A quick way to compare rental properties based on price and income.

Definition

GRM is calculated by dividing the property price by its annual gross rental income. It tells you how many years of rent it would take to pay off the purchase price (ignoring expenses).

Formula

GRM = Property Price ÷ Annual Gross Rent

Example: $300,000 ÷ $36,000 = 8.3 GRM

How to Use GRM

  • Lower GRM = more income relative to price
  • Compare similar properties in the same market
  • Use for quick screening before deeper analysis

Limitations

GRM ignores expenses, vacancies, and financing. Two properties with the same GRM can have very different actual returns. Always follow up with full analysis.
