Going perm in Cali

I finally made it out to California and I'm in love with it out there. I've been wanting to go perm to learn a new specialty in either the Cathlab or CVOR and I think I could be very happy being perm in Cali for the next 3 years and then I'll probably get the travel bug again. I have been looking at housing on Zillow and I think it would be a good investment to buy a house or condo in San Diego and then if I decide to sell it in 3 years, I could hopefully make a nice profit. It seems like California housing appreciates like crazy. Does anyone think this is a bad idea and maybe I'm better off renting? I can put about 120k down, I'm looking to buy something for 300k. And what can I expect to make as perm in either the CL or CVOR?
