I have had several California investors in the last couple of years. There is many good places to find property that would be good rental homes/condos/duplexes/ etc. What are your investment criteria? Are you looking for anything in particular? Will you be managing the rental property yourself? How much are you looking to spend? What are your goals for the property?
There are so many deals that are coming available now. Short sales, lender owned properties, etc. Just think about what your goals are, your criteria and then start from there. Good luck
