How does an appraiser determine the effective gross income?

Determining the effective gross income is a crucial step in the appraisal process, especially in income-producing properties. The effective gross income is calculated by starting with the potential gross income, which represents the total income a property could generate if fully rented and operating at full capacity. However, this potential does not account for factors that can reduce it, such as vacancies or tenants who fail to pay rent.

To arrive at the effective gross income, appraisers subtract vacancy and collection losses from the potential gross income. This gives a more accurate reflection of the income that can be reasonably expected from the property after considering realistic occupancy rates and payment defaults. This calculation allows an appraiser to provide a more precise evaluation of a property's profitability, which is essential for investors and stakeholders to make informed decisions regarding the property.

Other methods mentioned in the choices do not accurately reflect the determination of effective gross income. For example, adding all income and expenses would not yield effective gross income; it would instead lead to a calculation of net income. Similarly, adding estimated losses to potential gross income does not appropriately reflect the income that can actually be collected. Averaging income from previous years could give some context but does not specifically reflect the effective gross income for the current situation. Therefore, subtracting vacancy
