How to decided if you or the tenant is paying for utilities?

[Jonathan K.]

I'm trying to refine my deal analysis skill through trial and error and one problem I'm running into that is effecting my profit is when to decide if I'm going to be paying for water, power, and garbage? The real estate sites like Realtor.com, Zillow, and Redfin don't tell you this info so how do you guys decide who foots the bill for what?
