By Don Favia · Updated July 3, 2026

Direct Answer

GRM is price divided by gross scheduled annual rent. It is useful for quick comparisons, but it does not account for expenses, rent control, vacancy, repairs, financing, or buyer risk.

GRM is a screening metric. It does not adjust for expenses, rent control, vacancy, or repair risk.

How to Use It

Enter estimated value or price and annual gross scheduled rent. Use the result as a screening metric, not a final value conclusion.
