Determining “True” Market Rent?

[Chris Farinella]

In my area, I understand it’s typical that the tenant pays for heat, air conditioning and electric while the landlord pays for water, sewer, and sanitation.

When looking at rental comps in other areas (or even my own) how can I possibly tell if rent comps are higher because the landlord pays for utilities, or lower because the tenant pays?

Is it standard practice that rent is listed assuming the utilities are paid the way I initially explained?
