Yeah, I don't think you can broadly generalize about older houses like people are in this thread. It has to be more case-by-case. If a 100+ year old house has been well maintained over the years then it's not going to be much worse than a newer one. Different types of problems certainly, but it's not not automatically a junk heap. Whereas I've heard numerous stories of newer houses needing repairs or remodeling within the first 10 years because of shitty contractors cutting corners and doing a bad job.

Just did a full kitchen remodel on my 120ish year old house, with two kids in school. Once they are old enough you can actually use their help and teach them things.

(Although to be honest I'm a little premature in using the past tense, I've still got some trim to hang and I installed the blower motor on the range hood backwards, so I have to fix that before it's truly 'done').
