I'm questioning the use of some words here. While "space" may be on the list, it surely isn't there for the meaning "outer space". Someone who's education includes only those basic words/meanings, couldn't make any sense of it. so, "space" would be, maybe, "where t...

A difference, and the reason you can afford rent but not mortgage today is that the rent is lower, precisely as depreciation for the fact that you don't acquire ownership.
