The article mentions other documentation about primary residence, but doesn’t link to it as far as I can tell.

To play devil’s advocate a bit, plans and decisions change. At one point in time you can have one property a primary residence and later decide that you would rather use a different one as a primary.

Were these around the same time? Were they years apart? What are the legal requirements if you want to change your primary residence? None of that seems to be covered here as far as I can tell but is directly related to the topic and legality.

The fact she has 3-4 homes all over the place is excessive honestly, but neither here nor there about the legality here.
