Your preferred way to estimate utility costs

[Leslie B.]

When considering a property for investment in a new jurisdiction, what methods are folks using to determine/estimate the costs associated with water, sewer, garbage, and other utility costs which will be covered by the landlord? 

Is this something that can be determined/estimated easily and accurately before talking to the seller?

By what unit of measure do you estimate by (per bedroom, per unit, per square foot)?

In addition to what @Ryan Gillette said, you may be able to call the utility company and ask for averages of the property address for due diligence purposes of a purchase.
