Hopefully there is heat in the unit at the moment.

The house does need some minor cosmetic remodeling, but we are also concerned that the property has oil heat. 

I'd budget to replace it anyways eventually to save on heating costs longterm.

It is fully gutted as in no walls, heating, plumbing or electric.

These apartments share electricity and heat with their respective sides.

I also like to track my own personal expenses like fuel for my vehicle, home heating, and groceries too.

Despite this, the tenants are now asking for an electric line to be ran to the attic so that they can properly use the heat (in the winter) and cool (in the summer) because the current line is tripping the breaker. 

 Ohio Revised Code talks about is a landlord providing basics like running water, heat, and power to the property -- not garages and due to the fact that they are moving out in a month I would say don't do anything now.

We actually had a lot of success in St Pete, North Pinellas and Western Pasco, but even those areas are heating up.

I wouldn't be hesitant about buying it as a rental property - just make sure you factor in costs of a second second structure, since there are additional roofs, heat sources, ect...But in terms of renting it in my market, I think it would go fast and do just fine.
