I did a video on getting down to your NOI
after that (to get to cashflow) you need to subtract your debt service and capex reserves (I subscribe to capex being 'below the line'...a good explanation here:
CCIM courses on commercial real estate, and in our software, is to put the reserves below the NOI – in other words, not to treat reserves as having any effect on the Net Operating Income.
This makes sense, I believe, for a number of reasons. First, NOI by definition is equal to revenue minus operating expenses, and it would be a stretch to classify reserves as an operating expense. Operating expenses are costs incurred in the day-to-day operation of a property, costs such as property taxes, insurance, and maintenance. Reserves don't fit that description, and in fact would not be treated as a deductible expense on your taxes.
Perhaps even more telling is the fact that we expect the money spent on an expense to leave our possession and be delivered to a third party who is providing some product or service. Funds placed in reserve are not money spent, but rather funds taken out of one pocket and put into another. It is still our money, unspent.
