We don't have a crystal ball to know that a tenant with no prior evictions and a solid job history would suddenly be laid-off and turn to alcohol and stop paying their rent.

I also don't give money to women street beggars with babies that may or may not have been given alcohol or heroin to shut up and sleep quietly for hours in the cold and the wet on their laps.

@Dustin WoodleyI use a spray bottle of rubbing alcohol when applying silicon.

@Charlie MacPherson The seller is an alcoholic, for sure.

But I probably should have included in the contract that if they exceed the “average” utility consumption I oils charge then a fee.

They dont pay to be there, both alcoholics taking advantage of their dad and they have been physically abusive to him.

I'm surprised how little info there is on this topic that's for the consumption of the non-techie out on the web.  

It's led me to discover home monitoring systems like Eyedro (for electricity) and Flo (for water), where apparently you can track usage and figure out the consumption for a separate unit like a mother-in-law suite.

I'm not sure the electric bill would be higher, as central heat & air is usually more energy consumptive than a window unit. 

I would also remind everyone that marijuana possession and consumption is still a federal offense so Landlords are well within their rights to ban it from their property.
