I think it's a U shaped curve probably... lots of stuff breaks initially due to mistakes/defects, and then 10/20/30 years out. The sweet spot is moving into home renovated 5-10 years ago.

I've lived in a new construction condo as well as a 1970s home that had renovations in 1990s and 2010s.

New construction you deal with a lot of defects that show themselves in the first few years. You also contend with modern construction just being lower quality materials in a lot of cases unless you do a high end build for yourself. So the floors, cabinets, etc are going to wear out much faster.

My 50 year old house of course had a ton of deferred maintenance from previous owner that resulted in break-fix work on plumbing, heating, cooling, siding, roofing, etc.

I type this as I have 2 faucets, a fence, some driveway potholes and paver stones to mend, an irrigation head to replace and a new central air unit coming in next week. Dishwasher was replaced 2 months ago.
