Check everything like handrail on the interior stairs to make sure none of the brackets are broken, loose electrical sockets etc.It will depend on the age and condition of the house.

I have zero experience with this but how would you deal with electric and other utilities? 

So I basically would want a person who looks at the whole house and gives me the appraisal cost, the areas that need fixing (ex. kitchen cabinets, tiles, bathrooms, plumbing, electricity, etc.), and how much the cost would be.Then this way, I could decide to proceed or not based on the assessment.

Well besides the hard costs (construction, materials) and soft costs (permitting, architecture, fees, engineering) people often forget holding costs. 

If anyone out there is looking for trusted trades in HVAC, Electrical, Roofing, Foundatio, Framing, Painting, Drywall, Cleaners, Junk Removal, etc., let me know.

However, I strongly suggest to seek a structure engineer or architect/drafter that guide/help you on planning and dealing with zoning permits as well.

Focus primarily on the electrical and/or structural issues that come up. 

I'm a software engineer for a company called Accenture but I dabbled in underwriting multifamily on the side.

Does your shed have electric, plumbing, a/c?

That could make a difference because if you're in a heating climate with a gas furnace that could be cheaper to heat with than an electric mini-split as they become less efficient at very low temps. 5.
