Frequently Asked Questions
What is a good Gross Rent Multiplier (GRM)? ▼
A lower GRM (under 8 to 10) generally indicates better gross income relative to purchase price, whereas higher GRMs (12+) reflect appreciation-focused markets.
What is the limitation of GRM? ▼
GRM ignores operating expenses, property taxes, maintenance costs, and financing terms, so it should be followed by Cap Rate and Cash-on-Cash ROI analysis.
