Calculating CPA and Attorney Fees as Monthly Expenses

Hello!

I am new to the Real Estate world and still very much in the learning phase of my journey, but I had a question regarding expenses. One thing I noticed that was not generally being accounted for when calculating expenses on a rental property were any CPA and Attorney fees you will need to pay. Do people generally account for those as monthly expenses to help determine cash flow? Say I analyzed a property and determined the monthly cash flow would be $200. However, lets say the monthly average of any CPA/Attorney fees I incur is $250, so in reality by owning that property I would be cash flowing -$50/month. I have no idea how much those fees typically are, so it's very possible that example isn't super realistic. However, since I would not normally incur those fees unless I owned a rental property, I would think they would need to be factored in. Perhaps there is something I am missing or not thinking of, but I had not seen any information about it yet. Thanks in advance for any input!
