Yep, the big ticket items don't happen often, but when they do...Can't say I've ever replace a roof, paths, or driveway, in any of the houses I've owned. Maintained yes, replaced no.
I've never worked it over say a 10, 20yr period for my own home. But I have worked it out for rentals, and for me its less than service fees. Though I have used a agent to handle maintenance so its not like I do it myself.
My main point really is that people don't track what they spend maintaining a home, all the little bits they pick up in Lidl or wherever along the way, then they hear of €1,500 service fees and think that's expensive even though they may be paying more overall themselves. They don't factor time into it either, or the increasing difficulty of some maintenance tasks as they get older.
