⚠️
Common Mistakes to Avoid
Critical financial oversights that reduce long-term returns
✕
Using GRM as a substitute for Cap Rate or Net Yield analysis when detailed operating expense data is available.
✕
Deducting vacancy or operating expenses from gross rent before calculating GRM, which changes the metric definition.
✕
Assuming a lower GRM always means a better investment without examining operating expenses and property condition.
