Mine was built in the early 2000s so we are just getting through the first stage of stuff breaking. Couple of new faucets, new water heater, one new AC unit, new roof(luckily insurance covered). I absolutely do not trust the electrical in it. I've had 3 light switches go bad and I once removed a ceiling fan with the switch off but it still managed to trip a breaker.@wllm , if you haven't watched The Money Pit, do it. It is oddly cathartic.
We bought a home from 1967 and have had to redo about every major system and cosmetic thing in it over the past few years. Current fun project is figuring out how to get an overall electrical shutoff to the house because it doesn't have one and I need to change out my panel so my house doesn't burn down. Also have some fun plumbing noises coming from the hall bathroom shower anytime someone is in there and a toilet flushes elsewhere in the house. I kind of hate it. I feel like I am always holding my breath for the next thing to go wrong. I can't imagine what you are dealing with on a home that old.
