Gross Rent Multiplier
Gross Rent Multiplier (GRM) measures how many years of gross rent it would take to pay for a property.
GRM = Property Price / Annual Gross Rent
Annual Gross Rent = Monthly Rent × 12
GRM benchmarks:
| GRM | Assessment |
|---|---|
| Under 4 | Excellent — strong cash flow potential |
| 4 – 7 | Good — solid investment |
| 8 – 12 | Average — typical for many markets |
| 13 – 20 | Below average — appreciation-dependent |
| Over 20 | Poor — unlikely to cash flow |
Important notes:
- GRM does not account for expenses (taxes, insurance, maintenance)
- Lower GRM generally means better cash flow potential
- Compare GRM to local market averages for meaningful analysis
- GRM works best for comparing similar properties in the same area
- Always combine with other metrics like cap rate and cash-on-cash return
