Final answer:
The potential gross income of the building can be calculated by adding the rental market value of the occupied units with the income from the vending machines. In this case, the potential gross income would be $6041.67 per month.
Step-by-step explanation:
The potential gross income of a building can be calculated by adding the rental market value of the occupied units with the income from the vending machines. In this case, there are six units with a rental market value of $______ per month, but one unit is vacant. Let's assume the rental market value for the occupied units is $1000 per month. So, the monthly potential rental income from the occupied units would be 6 (units) * $1000 = $6000.
To calculate the potential gross income, we need to consider the income from the vending machines. Let's assume the vending machines generate an income of $500 per year. We can convert this to a monthly income by dividing it by 12. So, the monthly income from the vending machines would be $500 / 12 = $41.67.
To find the potential gross income, we need to add the monthly rental income from the occupied units ($6000) with the monthly income from the vending machines ($41.67). Therefore, the potential gross income would be $6000 + $41.67 = $6041.67 per month.
