When calculating the GRM, what information do you need?

When calculating the Gross Rent Multiplier (GRM), the essential pieces of information required are the sales price of the property and the rental income it generates. The GRM is a straightforward valuation tool used primarily in real estate to analyze investment properties. It is calculated by dividing the property’s sale price by its annual rental income.

Having both the sales price and the rent allows investors to quickly estimate the value of a property based on its rental income, facilitating comparisons between different investment options. This metric helps in assessing whether a property is priced appropriately relative to the income it can produce.

The other options do not provide the correct components for GRM calculation. For instance, property taxes, assessed values, and property sizes do not directly contribute to understanding the relationship between price and rental income, which is the core of the GRM. This focus on sales price and rental income is what makes this choice the correct one for the calculation.
