it's california! no one's leaving anytime soon, the housing prices will still be nuts, and if they leave they'll probably wind up making less!
they do have a huge chunk saved up between the two of them, which is good, compared to all the nutsos out here that do zero down, interest only loans. THOSE are the ones that you have to worry about in a few years.
i'm poor as heck (well to my standards, not by poverty levels) but i can't afford a house anywhere in this state (outside of the crap ass central valley, i'm not living there) but i'm still not leaving. my family lives here, i like living out here, and it's too hard to leave a state you grew up in, plus that i'll take an income hit wherever i go, even if it has lower car insurance, lower cost of living, etc.
no one can afford a decent house, i don't know how people do it. if my parents put their house on the market, they could get 900k easy, no repairs needed, extremely well maintained home in a very nice, quiet neighborhood, good schools, etc.
