Low density rented housing doesn't get things like solar either. In houses, even double glazing and windows that don't leak can't be counted on in my experience. I don't think I've ever lived anywhere as an adult that didn't have some things broken that I'd fix if I was allowed to (and would be fairly cheap to fix).

Some renters are rough on property, but many renters are not and look after the property the best they can, considering they are generally forbidden from doing any proper improvements or maintenance.

After all, many renters don't want to keep moving (and are not renting by choice), especially if they have children in school or a job nearby, so they have reason to look after the property they are in for as long as they can stay.
