In the land appraiser's income reduction method, the profit of the operator should be deducted from the total cost of the self-operated property. Why? Where is the basis?

There are two main ways for profitable real estate to obtain income: renting and operating. Net income can be measured in two ways: one is based on rental income, and the other is based on operating income. In real estate appraisal, because the net income of rental real estate is the net income generated by real estate, it is usually measured by rental income, which is a typical income method appraisal object. The biggest feature of commercial real estate is that the owner of the real estate is also the operator, and the real estate rent is inseparable from the profit of the operator. The formula of real estate net income is: net income = commodity sales income-commodity sales cost-operating expenses-commodity sales tax and additional-management expenses-financial expenses. Therefore, self-operated properties need to deduct the profits of the operators.
