NOI vs Operating income and EBIT

Dear All:

What is the differences among these terms: NOI (net operating income), Operating income and EBIT?

It seems to me in te Real estate investment, the concept of NOI is so confusing.

Thank you so much for your time.


Opperating income and EBIT are the same thing in CFAI books. NOI is used only in real estate and is

Gross income - expenses from vacacny - bad debt - operating expenses = NOI

I did not see anything in the LOS that said we had to calc NOI.
