Not to keep too far off-topic...

My house is massively badly wired. The previous owner was an expert tile person. He re-tiled the house incredibly well (although it was in the 70s and 80s, so the color choices are a bit dated now.) Sadly, he also fancied himself an electrician and plumber. And was woefully unqualified at each. When we remodeled the basement, we basically had to rip out all of the wiring and re-do it, it was so bad. Before, I never felt very "safe" plugging any of my vintage hardware in to any of the circuits. Now I at least have three "good" circuits for them, even if the main floor is still all kinds of wonky. (Don't even get me started on the switches.....)
