Anyway, before I jump and make an offer I plan
to get it inspected.

When you say "inspected" do you mean by one of the pre-buy home
inspection companies that have sprung up in the last 10 years?

If so, I would advise not spending your money in that direction unless
you have a lender involved that wants a letterhead from "Bob's Licensed
Home Inspector". Because with a 100 y.o. house as you describe, the
best the home inspection company will be able to give you is a letter
full of maybe, could be, potential problem, issue, advise you contact a
structural engineer, etc. And realistically, given the potential for
liability, that is all they can do.

Instead, I would hire a general foreman from a well-regarded remodeling
company for a day (think $50/hr for 8 hours + buy lunch), buy a pair of
coveralls and a good flashlight, and spend a day with that dude crawling
through every inch of the house and surrounding property. You take
notes, because he isn't going to give you a written report or sign his
name to anything, but he will be able to give you a realistic
understanding of what does/doesn't need to be fixed, what the potential
failure areas are, and how much it will cost.

The kind of property you describe is a lot of fun, but be sure you have
a good chunk of cash in reserve for the "known unknowns".
