The neighborhood is desirable for the area, new homes planned to be built a couple streets over, high elevation, no flooding and underground electrical (electricity is fine after the storm). 

The electrical and plumbing is completed.

Oh, and for some for not-so-good news this property happens to have bed bugs and a putrid smell from animals & rotting food in the fridge.

Think how much you know about remodeling so far, whether you have tools, a truck, and how deep you can go (anyone can paint or clean but sheetrock, trims, windows, sewer line... electrical and plumbing often require permit).

Standard repairs (bathroom, paint, roof, electrical upgrade, clean up etc.).

Also you have to decide what to do with electrical wiring.

Replacing roof, HVAC, water heaters, etc. can certainly change the math quickly on a $100k property.That said, if its currently rented you can assume the plumbing and electrical systems are at least functional.

For me I bought a place infested with bugs.  

I'm looking at a multi-unit deal in Delaware County right now where the current owner pays all utilities except in-unit electricity.
