Expanding your portfolio will take some time, I'd be patient as your main goal of cash flowing is attainable and you sound to be on a good start.

So my original strategy this year was to house-hack a 4-plex to begin building my portfolio.

Being my age I am considering looking into another job that relates to real estate that will give me more experience and insight into the industry which will allow me to apply it to my own future portfolio even if it means taking a reasonable pay cut.

Finally, with the use of Trusts while establishing these structures you can add a level of anonymity by removing your name from public record.When I work with my clients to discuss asset protection I navigate with them through: the size of their portfolio, their level of exposure and their future goals.

My long term goal is an extensive rental portfolio.

Having worked with many CA investors, most of my recommendations vary drastically based upon what their portfolio and goals are.

Have any properties under your portfolio yet?   

Otherwise I feel a well balanced portfolio has both.

I have a portfolio of properties on JAX.

I have 3 properties in my portfolio and come across many amazing deals everyday given I work full time as a wholesaler.
