During the term of the lease (the initial term of the lease or any extension term), the owner may only terminate the tenancy because of: (1) Serious or repeated violation of the lease; (2) Violation of Federal, State, or local law that imposes obligations on the tenant in connection with the occupancy or use of the unit and the premises; (3) Criminal activity or alcohol abuse (as provided in paragraph c); or (4) Other good cause (as provided in paragraph d).

Further, an opened notice from the DMV in this tenant's name related to driving under the influence of alcohol was on the floor, and an unsecured Smith and Wesson handgun was sitting on the bedside table.

Liability out the wazoo-- roommates bringing guests over, complete strangers living with each other (alcohol, assault, drugs, etc.).

I have a 2 family that all the utilities have been sub metered so each tenant can be billed based on their individual consumption.

@Joel Owensbecause a large portion of our sales is alcohol, which is high margin, we are hitting in the 20-30 range.  

In Michigan, you can insert this clause in your Lease:ILLEGAL DRUG USE: Tenant must not violate, or knowingly allow another to violate, federal, state, or local laws regarding the use of controlled substances or the use of alcohol by minors in or around the premises. 

The boyfriend of her's might have sold it for their drugs and alcohol.  

Indeed, the entire monetary system of debt consumption is designed with you being the slave.

I have sprayed the White Shellac version and it needs denatured alcohol for clean up.  

While sub-metering may have been the "right" thing to do, it was not the right business decision in that instance.As previously stated, I am in agreement that holding everyone accountable for their resource consumption is they way things should work.
