No Alignment
This is one of the living problems that doesn’t make the home itself annoying or unlivable, but can definitely be problematic for a homeowner who gets OCD from poor alignment. But you would have to really inspect your home in order to find this mistake. However, that isn’t the only thing that could bother the homeowner.
A person obsessed with alignment may also care a lot about smooth edges, which is why the homeowner wouldn’t be a fan of the outdated popcorn ceiling. Of course, the popcorn ceiling can be removed by scraping, but imagine how long it would take to scrape every inch of the ceiling in a home.
