The definition of "gross rent multiplier" (GRM) is accurately described as a rule of thumb metric used to estimate the value of rental properties based on gross rental income. This metric is particularly useful in real estate valuation, as it provides a quick way for investors and appraisers to assess the potential value of a rental property without delving deeply into more complex financial analyses.

GRM is calculated by dividing the property's sale price by its gross annual rental income. Once the GRM is established for similar properties in a specific area, it can be applied to a rental property being evaluated by multiplying the gross rental income by the GRM. This simplified approach enables quicker decision-making in property investment contexts, allowing investors to gauge whether a property's asking price aligns with its income-generating potential.

The other options do not accurately reflect the purpose or function of the gross rent multiplier. While property taxes and repair costs are important considerations in real estate, they are not measured by GRM. Additionally, while property appreciation is a factor in real estate investment, GRM specifically focuses on rental income rather than appreciation.
