Rent by the room: Utility strategy

[Zach Wright]

I am actively searching for my first house hack deal (western MA, > 4 bed 2 bath, single family/duplex, <250K).

I am wondering if anyone has experience dealing with utility expenses while renting by the room. I understand that, generally, the owner takes utilities, as it is impossible to measure usage while renting by the room. 

I'm interested in any strategies to mitigate this cost (other than building into the rent). One strategy that I'm aware of is utilizing coin-operated washer/dryer to offset some electric/water costs. I'd love to hear of other strategies!

Thanks - Zach
