The “total number of owners” link goes here. I’m not really sure how to read what come up, though. I actually wonder if the site was bugging out.
Here’s the actual exchange. Not to give them traffic, but maybe like me you want to click through to something else.
According to other people in that thread, it goes down to 30% or 40% if you don’t include people who just live together with a homeowner. Honestly that doesn’t change the story much for the purpose of OP, IMO.
