Income section of Profit and Loss Statement

[Barry Sanders]

Have been building out some financial models and want to make sure Im doing this correctly. When formating your Profit and loss statements do you include an allowance from gross potential rents for all three of the following or just 1, if so which ones? 

Physical vacancy

Economic vacancy 

Loss to lease

Are these allowances  applied to rent income + other income or only rent income to determine effective rental income/operating income? 

Thanks in advance
