A salesperson has the opportunity to list a 6-plex that is 100% rented. If the salesperson does NOT want to account for any expenses, the numerical tool used to predict the price at which the building will sell is known as

The net rent multiplier (NRM) considers the net operating income of a property after expenses have been deducted. Since the question specifies that no expenses are to be accounted for, the NRM is inappropriate for this scenario, as it requires a detailed understanding of the property's expenses and income.

Return on investment (ROI) measures the profitability of an investment relative to its cost, typically expressed as a percentage. While ROI is a valuable metric for evaluating the performance of a property, it involves comprehensive calculations that account for expenses, making it unsuitable for predicting the sale price of a property without considering expenses.

The gross income multiplier (GIM) is similar to the GRM but typically includes all sources of income, not just rental income. While it can be useful for evaluating properties with multiple income streams, it is not the most straightforward method for a property that is 100% rented and does not require expense consideration, making GRM the preferred choice in this context.
