I find the terminology strange. Are more homes in these states not owned? Undoubtedly, the difference is the homeowner is someone who doesn't live in the building, and merely rents it to another, and thus a landlord. But, in a sense, all homes are "owned" (some exceptions, like large squatter population, Detroit, etc).
Right. Every home is owned by someone! Occupant, landlord, or as in our case, both.
