Even for the $250k houses (and there are starting to be a few, so far dogs, but soon decent), you still have to have jobs.
If nominal UE is "only" 11%, you know that U-6 is 20% or more. And for the undocumented community, I would bet that 'underemployment' is even higher. Fewer hours per week of landscaping, construction, fast food, janitorial, etc
$8/hr x 20h/wk x 4 workers = $2500/month gross. Not enough to buy, or even rent those $250k houses.
I only see downward pressure for several years for the west-side, along with SA, Anaheim, GG, El Modena, parts of Orange, HB, Tustin...all the way down to SJC
