These properties are generally in high demand, but on a positive there will be drastically less new inventory of competing rental properties. 

So, even when the market is challenging, you can still see properties and stay current.Don't take a break when the rates are high.

I just wasn't sure if it is my responsibility to do something if the electric bill is high and are not satisfied. do I have to be concerned about that?

"Good" areas will be priced high, "Bad" areas will be priced low. 

I would protect myself and cut my losses so I was not looking over my shoulder or getting high blood pressure every time I heard a knock on the door (hoping it is not the FBI showing up to ask you some questions).
