What is the Gross Rent Multiplier (GRM) formula?

The Gross Rent Multiplier (GRM) is a crucial metric used in real estate valuation, particularly for investment properties. The formula for GRM is determined by dividing the selling price of a property by its gross monthly rental income. This calculation provides a straightforward way to evaluate the potential return on investment for rental properties.

By using the GRM formula, investors can quickly gauge the relationship between the property's price and the income it generates, allowing for comparisons across different properties. A lower GRM indicates a potentially better investment because it implies that the property generates more rental income relative to its price.

In contrast, the other options present incorrect formulas that do not accurately reflect the relationship intended by the GRM. The correct formula effectively highlights how much an investor is paying for each dollar of rental income, making it a useful tool in property analysis.
