On top of this if at all possible I’d recommend choosing specific neighborhoods to become an expert on as opposed to just thinking “anywhere in the San Antonio market could work”.

I like that your goals are realistic and not insane like some new investors.

You’re in a great position with a property that’s appreciated significantly, a low-interest mortgage, and clear goals to boost cash flow and transition into full-time investing.

My goal is to become an expert in property management.

Would love to hear more about your goals and exchange ideas!

Each option has different implications, so choose based on your financial goals.

My goal is to buy one rental per year with price between 150k-250k for the next ten years (if i get to keep my job). 

It seems where you've chosen to move doesn't line up with your goal of reaching financial freedom?

My goal is to build a portfolio of single family and multi family properties. 

If you do have to move because of a job, you would be safest (in my opinion, i am not giving legal advice or financial advice), i would sell that property to ensure that you did not just purchase with the goal of moving out early and taking advantage of lower rates and lower down payments for purchasing your home as a primary residence.
