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?

That was exactly my concern.

My concern is with the house that my dti numbers will remove my options for a loan.

Maybe look for a different type of tenant that doesn't leave every year or sell the place if it isn't meeting your other investment objectives.2) As PM's we always seek prior authorization for expensive turns or capital projects, even though the estimates given to our owner-clients are often ball-park numbers.

This leads me back to my mother, as she approaches her end years, I hate to think about this, but she wants to leave my sister and I one of the houses I mentioned earlier.

I understand the cost concern.

I would not give notice to leave somewhere until I had a place lined up. 

The first thing I want to point out is that it may be wise, in your thinking, to separate the property itself from the STR business that's being run from the property.In the old days (as recent as 10 years ago), people buy a vacation home to enjoy, and they leave it empty when not in use. 

We are in a safe community, so tenants can choose to leave the door unlocked or hide a key under the mat.

From a lender standpoint I think the main areas of concern with auction properties boils down to access.
