Marketing Duplex and Utilities

[Sawyer Nyquist]

Hello BP,

We are just finishing renovating one side of our duplex and I am about to begin marketing the property. 

This is my first rental, so trying to be extra diligent about screening tenants and showing the unit. 

Question: The unit has radiant electric heat in the ceilings. While the heating is effective (it keeps the place warm) it is not very efficient. 

We live on the other side and our winter heating bill has been $150+ each month and we have a wood stove that we run all the time (which the other unit does not have). 

How much should I disclose to the interested tenants about the potential costs of heating the unit? I don't want to scare people off by telling them they will have $200 electric bill. Or have someone move in only to freak out a month later when they get their first bill. Especially because I think there are ways they can manage the situation and keep things reasonable. Should I share with them what our utilities are? 

Thanks for your help BP.
