What can i keep (id ideally like to keep the bathroom and electrical) a enclosed stairwell/ porch connects them would I need an additional stairwell to be built?

@Lon Sierra - Can you pay an electrician to separate the electricity and add another meter / panel? 

Has original electrical work. 

Storm pond, storm sewer, fire hydrant, fire suppression systems, fire walls, electric metering and voltage (3phase???)

Advise the tenant that you are very serious about rent collection and do not ever waive late fees.Procedure for allowing a pet or clarify that they may never add one.Where the electrical breaker box is, main water shut off and instructions on how to operate.You should have most all other policies and procedures codified in your lease agreement. 

You could look for a house that already has the right plumping and electrical lines run down there so the costs would be minimal.

The materials can always be cheap and there is not much to the house in terms of plumbing and electrical. 

All new electric, plumbing, HVAC, etc.
