@Neil S.I can't speak about SoCal, but since you're from the area, these two posts I wrote here about Stockton and Sacramento will definitely apply to your situation:https://www.biggerpockets.com/forums/621/topics/396725-millennial-migration-to-sacramento-2017---here-comes-the-rushhttps://www.biggerpockets.com/forums/627/topics/424510-how-to-invest-in-stockton-ca---a-detailed-overviewCheck those out and see if it sounds like something that might interest you.

For example Mexico has had negative net migration (more people moving back home than coming to the US); partially because their unemployment rate is even lower than ours and Mexico is the 11th largest economy in the world.Another piece of the puzzle is that working class people are getting killed on rent increases in Seattle so they need to make a decent wage just to be able to have a roof over their head.

Lower taxes, low vacancy (IL migration in full force), and better land lord laws.

Well, until you are ready to migrate to Cuba or Russian or North Korea, suck it up..... 

I noticed that the fees had migrated to GA.
