Mike,
I fear that many owners simply don't understand accounting and the implications of depreciating assets and that they are real.
Everyone grasps the idea of prepaid expenses, we pay our yearly insurance and each month we take off that portion that has been used, if we cancel the policy, then we get back that portion that is as yet unused.
But try and explain that about a roof. A new roof might cost say 12,000 for a building, but it occurs once every 12 years, but do most owners actually budget for the resulting 90 dollars a month in cost? Of course, no.
Therefore, getting most to understand that simply because the bill wasn't presented this year, doesn't mean it isn't there, is a bit of a problem. Add baths, kitchens, heating/cooling, etc, and it is no surprise that owners feel blind-sided by bad years and unusual expenses, I don't see them, therefore they aren't real.
If, in formulating a general rule, we say that depreciation is real and just, and that as a general rule of thumb, expenses must be related to that depreciation number as a MINIMUM, then
1- This might help in actually creating a provable and accurate general expenses formulation, of course this would require actually holding property for the depreciation periods selected by the accountants and business managers.
2-
Now aswe add in the property taxes, insurance numbers, and their tax implications on the total true expenses, I think it will be clear that expenses are actually far greater then the 50% rule generally used.
Finally, anyone who believes a realtor's assessment over that of an accountant, well, lets just say, there is no Santa, regardless of the sales person who thinks there is, and the investor needs to be aware or they will learn that the hard way.
