To me, its a combination of the two items - the LTV you're getting all-in at and the cash flow the house will be generating.

They will wash 1 or 2 items at a time, do other people's laundry or others outside your building will start using the machines.

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 have a pretty crude proforma built, however if there is anyone who knows of a more detailed tool better suited for multi-family that would better capture performance/returns factoring in the delayed start of lease-up and absorption rate from there, I'm all ears. 

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.
