I admit it's awkward phrasing. I try to be accurate.

About half of US adults own their home. It goes up to ~2/3 if you include adult children, grandparents, etc. that live in the house but don't own it.

I wasn't trying to dance around this fact; my point is that a large fraction of the voting public has their interests aligned with keeping home prices high (presuming that these non-owning residents share interests with the people that do own the home).
