I owned a house that was built in 1871 for about 13 years. Fortunately it had been updated & remodeled by the time I got it, but here would be my suggested approach.
 ​​​​​​

    Get the foundation sorted & solid. You may not have to redo the whole thing, but it's worth getting it right before you do anything else.
     
    Sort out the electrical. Since it could potentially burn the whole place to the ground and/or kill you & your family it's worth doing this right too.
     
    Sort out the plumbing, or at least the parts that won't be easy to access later.
     
    Windows - do whatever you can to prevent air leaks, up to replacing the windows if needed.
     
    Insulation - don't skimp at all, the more insulation you can install, the more it will pay for its self.
     
    Roof - repair or replace as needed.
     
    Remodel/updates - this is completely up to you & your budget/desires. It could be kitchen/bath, flooring, redoing the interior walls/doors, and/or exterior siding/paint.
     
    Gigantic garage or pole barn - hey, it's GRM after all.
