No direct exterior maintenance issues; the condo fees and the condo assn pays for snow removal, lawn cutting etc as well as major improvements like a new roof. It’s not a good deal in my view but some like it.
It makes sense for people with certain allergies who still want to own their own place. My brother has a condo. He’s allergic to dust, grass, and pollen, so just the lawn-mowing service saves him a lot of suffering.
