Hmm. I think the follow-up is plausible, actually. I found another article that said this:
More than 750,000 poor people own homes worth more than $150,000; nearly 200,000 own homes worth more than $300,000.
It supposed comes from a government report.

This makes me believe that he got his facts from the Heritage Foundation.
I'm going to have to do some more research on this, but I think they may be correct.
