I moved into a place that hadn’t been touched by original owner since 1977 a couple years back. I’d say we’re about 60% through a complete remodel with bathrooms being the expensive thing we put off.
My only previous place I owned was newly remodeled when I moved in so I had practically no diy experience.
Some things I had professionally done I thought later “no way I could have done that”. Other things I now laugh that I had to pay somebody to do it at the time, actually embarrassed. I enjoy the work if the tools for job aren’t prohibitively expensive.
If a place is really old it’s crazy how much paint, new door hardware, new outlets and new light switches can brighten it up as diy projects. We’re replacing windows in a few months, more for noise than looks. Maybe years still to tackle bathrooms beyond diy projects.
