You will also have to pay for the new electric meter socket, wire to the transformer, and electrical panel inside the house.You may have to re-do the plumbing in the house to split up the two sides of the house so they can be on separate meters. 

I learned how to wire an electrical panel by myself.

You'd be stuck upgrading things like electrical service, panels, arc fault breakers, etc. if this where the case. 

Everyone seems to just tear the slate off of them and go with a metal panel roof anymore .

This will require a credit pull (good credit), required inspections (termite, perhaps wood destroying organism, perhaps wind mitigation), and most importantly a good insurance policy (those inspections must pass, and all safety issues corrected...no holes in walls or floors, siding on, good roof, passable electric system...no Federal Pacific panels).  

So when you show up with comps illustrating garbage properties, expect the panel to ask you how you selected your comps, and if you made any improvements.They will ask about your rents.  

Thanks for any inputHi Nick, To add to this discussion, anything that is high dollar, such as utilities so plumbing, electrical panels, HVAC, anything structural, windows can get really expensive.

However convincing a judge or regulatory panel later that it is not an unlicensed business may be more challenging.Disclaimer: I am not a lawyer and not offering legal advice.

. ~$150 from HD.Solar panels on roof.Automatic sprinkler system.Would these be worth the expense?

It has hardwood floors and wood paneling throughout.
