You can fix this by talking to the utility provider about creating "equal billing" or whatever they call it in your area.

Don't disqualify yourself without talking to an expert. 

Before you get there I would try to acquire a few properties however you like such as creative financing, just to get you some cashflow and to continue to grow your portfolio.

I also have a mortgage on this property paying $683 a month.Now I'm deciding should I continue waiting for a possible tenant or should I just sell the property.

Maybe that is your best route or maybe it is not, but if that is the only loan the LO you are talking to can make to you then guess what kind of loan they are going to suggest? 

My advice is to be wise but continue.  

I have a good team helping me, I have a good system, I’m confident in my ability to talk to sellers because I’m a real estate agent and just am nervous that I should be trying to reach more people.

Talk to the seller, but options are to cancel the sale (and risk losing your deposit), renegotiate to lower the price to allow you to fix the problems or ask them to fix it. 

Yes I have known it to work because the owner is not a push over, enforces policy and can make it run good......however, do you have the right personality to do this, AND if you move out can you continue to have the house run smoothly with no one in charge.  

I am in talks with a couple people now.
