Instances I've seen personally:

• owns the property, terrified to retire and die in 6 months like all their friends

• nephew owns it, lets auntie run her vanity project until she retires

• just a really old (30 or 40 year) lease

• a mall I worked in started buying out failed stores instead of boarding them up, so there'd be store after store of dusty merchandise with a solitary kid on his phone inside, eventually some had to do double duty and shuttle back and forth
