If its a deal breaker in your market for your type of tenant well then you have to do it.

Had all 3 going and the breaker shut them down. 

A check into the circuit clerks office revealed that she hasn't even been served with foreclosure papers yet.  

If every month they are paying late (Not entirely a deal breaker for me, I have one tenant who pays on about the 21st of each month, they have been my tenant for 3 years) but lying about why they are paying late, then Id be more in line with @Roy N. suggestion of starting the eviction process.However I will say that the bedbug thing possibly complicates this slightly on a couple different levels. 1) if they move out...I really suggest getting the property treated for bed bugs, and I recommend the heat treatment process for this.

She makes three times the rent though but is the bankruptcy a deal breaker?

Circuit breaker has flipped (basic I know, but you didn't explicitly say you checked the breaker so its worth double checking)2.

This could be a deal-breaker for me.

The difference is like $2K which is not a deal breaker in any way, but the issue is you never know where else you will need extra spending. 2 HVAC technicians said, you have to put brand new ductwork.

Most importantly make sure they know how to shutoff water, flip off main breaker, etc.

Is the electrical service adequate for most commercial usage, at least 200 amp service with sufficient circuits.
