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?

I'm assuming I won't have that high of purchasing power, and therefore I believe partnering with my former boss would provide the "backing" i would need. 

We had to do a lot of electrical work, bathroom, kitchen rehab, total paint and a new roof.

You’ll need to treat it like a business—handling tenant management, accounting, legal compliance, property maintenance, and more.That said, when done correctly, it’s a powerful tool for building wealth!

There is a small park about a mile from the property, so I know the infrastructure (water, electricity, sewer, trash) is available for a build. 

Napoleon Hill's masterpiece takes a dive into the power of the mind and the principles that lead to success.

Of course not, but required items such as electric, water, gas, and plumbing all need to be in working order.

yeah the tenant pushing back is my concern. it just so happened that this happened with the tenant that seems to not like paying. and the heating is electric and this winter has been extremely cold which caused the electric bill to jump up to $800!

Quote from @Aaron Wolman: I would call the companies (gas/water/electric) to get estimates, or an estimator out there.

The property next to me is a 1 acre lot, it has a Well, Septic and Power, but no structure.
