If you learn the costs for the common items and the big dollar items first, that's a good start.

I think I just want to see it because i'm sure there are some maintenance items and then after that really calculate my fee which doesn't have to be a crazy amount.Thanks everyone for your feedback.

One way to deal with this is to put aside a certain amount per month to pay for higher capex items.  

The standout item for me is $0 fixed expenses; that seems like a miss.

Buy items on classifieds for cheap and resell them for a profit. 

I itemize every expense for my clients: repairs, supplies, etc.

I have learned that it may be beneficial to itemize everything carefully with quality bookkeeping.

Diversification is Key I have always believed, even more so during times of heightened volatility, that diversity is the key to any successful business or investor strategy.

You have to factor in the age of the building and the age of all CAPEX items I listed above.

My bare minimum for those 2 items is $150 per month.
