Expenses with parental property

Title: Expenses associated with rental property

I have been trying to determine what profit I would have left over each month after bills were paid for a rental property. I have yet to buy so I want to have a god idea of what's to come as far as bills go so i can get into my first deal. Below are the expenses I believe I must account for when evaluating a rental property. Please tell me if there is anything I am missing:

Fixed Expenses:

electricity / water and sewer / PMI / garbage / insurance / property taxes

Variable Expenses:

vacancy % / R&M / CapEx / Property Mgmt.

Any suggestions as to what are good % to use when determining the variable expenses?
