Looking at a duplex where the current owner pays utilities simply because there is no si meter for water or electric.If I were to try and sub meter it, how much would that cost?

I'm thinking at this point Buildium may be a better option simply from the cost standpoint.

I am simply asking is there an opportunity for me to negotiate a better deal based on what we are bringing to the agency?

Plenty of options if you are creative . . . just remember that the line "buy with no money down" is a con . . . you simply need to find a way to buy with someone else's money other than your own. 

They are simply different. 

Should I simply tell them to keep their AC units at 78 degrees when they are not home?
