GRM

GRM is an acronym that can refer to multiple concepts across different domains. Notable uses include the following:

- Gross rent multiplier (GRM): a real estate valuation metric defined as the property's sale price divided by its gross annual rental income. It provides a quick, though rough, sense of value and is typically used for quick comparisons rather than precise appraisals. It does not account for operating expenses, vacancy, or financing costs; higher GRMs indicate a higher price per rent.

- Groupe de Recherches Musicales (GRM): a French institution dedicated to sound research and musique concrète. Founded in the mid-20th century, it has played a central role in experimental music and audio research; INA GRM continues its legacy today.

- Germplasm Resource Management (GRM): a term used in genetics and agriculture to describe approaches for cataloging, preserving, and utilizing plant genetic resources in seed banks and gene banks.

Because GRM has multiple meanings, the intended sense is determined by context.
