Question about Water/Sewer/Garbage costs in Chicago

[Adam Sporinsky]

What do other investors typically pay for Water/Sewer/Garbage service annually for a property in Chicago.  I am specifically looking at 3 and 4 unit buildings, and I don't know how to accurately estimate these costs.  Does the area or neighborhood matter for these prices?

Are there other utility costs I should be including in addition to these?  The properties I look at all have tenant paid electric and gas.

Any help with this is appreciated.

I average $40 a door for water/sewer but others average less.  I heard some say $20 but I've never seen those #'s maybe that is single occupancy and not families 

I haven't got a bill with Garbage added yet but I heard it would be $10 per month
