a.4) How to draw multiple utilities to each unit such as Sewer, Gas & Electric?

If your looking at gut rehabs, then it may work.As for your utilities question, if you want your tenants to pay for them, they would have to be split before the house (for water) and at the house (for electricity and gas) with separate meters for each unit. 

I have a property in Oswego, IL on which the gas meter has been removed.

What about the Gas? 

pretty active market,  returns are pretty good, not as good as during the $4 gas era but still better than alot of areas.  

In that case you need a sub meter on the electric, water, and gas (if present).

The designer contacted me in December and said that the original gas main would not be turned back on so BGE would need to engineer a new gas line to my property.

Any new tenants should pay their own gas bill on day 1.

I still pay for the gas for the heat but the tenants pay the electric/AC.Now, we have the 2nd floor apartments partially framed out.

So you have to take the check to the bank and have it converted into cashiers checks to your creditors like gas company, car payment, credit card payment, etc.
