Seperate metering and utilities

[Dan Chandler]

I'm looking into a duplex right now but there is a giant red flag with the utilities...

The tenants pay the gas but the landlord is responsible for water, sewer and electric.  They have added solar panels on the back of the roof to help but everything I've read has been to stay away from a property that doesn't have separate metering.  So I have 2 questions...

1.  Should I abandon this property just based on this fact alone? 

2.  If I stick it out and the numbers make sense, does anyone know how much it would cost for me to have this converted to separate metering?

I'm open to all stories and advice... The good, the bad, and the ugly.
