In the first couple of years I remember getting so irritated by all the time it took to take care of the house and yard. Nowadays, I've gotten used to it, and I view it as a welcome distraction from work, but that definitely wasn't true in the beginning. Even paying someone to do all these things is a large hassle. You have to be at the house to meet contractors, get competing bids, worry about the contractors doing stuff wrong, etc.
I also think people wildly underestimate maintenance costs. I bought a 50 year old house, 10 years ago. I don't think I've had a single year where I didn't have to spend 10K on maintenance. I always wonder how most people handle these expenses - and then I realize that most people just don't take care of their houses.
