What to do with expense money left over.

[John Corum]

For tax and income purpose, what is done with left over expenses withheld before NOI. I mean, what do I do with it? Do I clame it as income if not used, use it as a mandatory cap-x and dump it into the property, take it as income, or put it toward principal if I have a loan? What if I own a property out right, which is what I have? 5 units on one plat!!
