I’m 54. Single, no kids or partner, live alone. I made the choice to move to a ground floor rented condo back in 2008 as I’d lived for years in apartments with a ton of stairs. It was a good choice as I later developed sciatica and knee issues. I doubt I will ever buy. That’s OK with me. I’ve always rented. It means I can move as needed, if I want to, at the end of my lease. It’s a small space so easy to care for.
