Hey man I’m originally from Vancouver and I live in Southern California.
I agree that Vancouver is in an unrealized housing bubble. I was shocked that the sales numbers were so strong this summer.
As far as Socal goes. Basically, the coast is expensive very expensive. Since your Canadian and dry heat and sunshine is probably what you’re looking for (the ocean doesn’t need to be right next to you). Look for nice middle class areas inland and you’ll get more bang for your buck.
Clean air (Vancouver Style )doesn’t exist in Southern California. Tap water down here is not so good. You will need to adjust your lifestyle.
In San Diego, that would be Poway or Eastern Rancho Bernardo. Mission Viejo or Irvine in Orange County. Not sure in LA. You could move to Palm Springs it only 90 minutes from LA and there are tons of foreclosures. Its very very hot in the Summer. Have you considered Scottsdale, Arizona?
