I was going to comment on the ridiculousness of someone living in LA and working in Riverside. I didn't read the article because I don't want to give it a click, but unless he has a partner who works in maybe Santa Clarita, or somewhere north or northwest of LA, that's absolutely stupid. Even if the partner works in LA, the would likely do better living in Riverside, or maybe parts of Orange County. It's an entirely nonsensical commute.
As for not wanting to live in the bubs, sure. But he basically works in the burbs. (Using a broad definition, since Riverside is it's own city--and county-- but tends to be largely bedroom communities, without much of an urban downtown.) I don't want to live in the burbs either. But I do because spouse happens to work in the burbs and it is a 10 minute commute, while also being much cheaper than living more urban. It does mean I can't walk to a grocery store, or much of anything. But if it is more important for this guy to live in LA (and have an hour+ commute) than to own a home in the burbs, cool. He needs to own that he's making that choice and stop whinging about it. It's not impossible for him to buy a home. It's impossible for him to buy the home he wants in the exact area he wants. That's a very different situation.
It's entirely disingenuous for him to say he can't afford to buy a home. That's like me saying I can't buy a home... because I want to live in the heart of Paris and everything there is too expensive. And I don't even actually work in Paris.
