In NW Austin 10616 Mellow Meadows, 78650 was converted from apartments to condos--with, I kid you not, a coat of paint slapped on and new carpet--and sold to Primarily California investors for around 150k per unit. come 2010 I often stood next to a guy at the courthouse auction and he would bid 35k but only for the 2/2's. not thev2/1s. I saw one 2/2 go to a couple for 50k at auction. They'd list for 55-60k on the ML and sell pretty sell fast. They were never worth anywhere near what the investors paid. California is so expensive everywhere else seems dirt cheap.
One guy who did seminars in California sold brand new homes in two Round Rock golf course communities. If those investors managed to hold on they are now okay because Austin didn't decline much and now Austin rents are way up. But I saw at least a few 3000+ sq ft investments at one course auctioned off in the crash. One California investor had financed hers as a second home and had subsequently taken out a home equity loan. then foreclosed. Taxes are over 3% and HOAs are 85$ month at the golf course communities. The smaller 1600 sq ft were originally 150-165k and I only saw owner occupied short sales there--with job losses I presume. That is what the seminar guy owned or owns, a small one story on the golf course.
I recommend stocks for a California twenty year old. learn to read a balance sheet and buy micro cap stock if you want to be involved, otherwise dollar cost average in a total market etf.
