This is also not a surprise that they don’t own the land. At any time they can move their mobile home, unlike a house or condo. They fully know what they signed up for.
A Condo owner owns the land and pays property tax and HOA fees, which can be steep, so there's land appreciation.
Why pay so much every month to get zero land equity and zero home maintenance?
Run some numbers. I did sometime back. And don't forget, these are microscopic lots. Barely room for a couple of storage shelves under a car awning.
The references say that the mobile homes depreciate, so they're not even worth moving, and landlords charge anyway. I linked to very short ones that bring up key issues.
In a condominium you are a member in the association that owns the common areas and have a voice. The board is other people who own condominiums there, and will at least try to do things in the best interest of the condominium owners.
