Plus I figure even if I plan to flip and it doesn't sell, I can rent it for a year with minimal cash flow and try again the following year but I have a couple other rentals that cashflow that can offset for a little while. 

So some of their replacements are minimal leveraged and some are maximal leveraged. 

This allowed me to save money to invest in real estate when I turned 18 however I have minimal past income. 

@Matthew Irvine  I think if growth is minimal but cash flow is good you can still make a good investment.

I'm eligible for a VA loan so 0 down but to minimize the funding fee I can put down 5-10%.

I was thinking about starting a local group in my area, but I have no idea on where to begin and if it is a good idea for someone with my minimal experience to do so.

Id have to raise rents to really see any cash flow and then its still minimal.

You can install it in basements below grade, etc, due to it's minimal expansion and contraction (in comparison to other wood).  

In other states, HOA fees are minimal, but here in California as you have seen, HOA fees can be us to $500.

Without bringing up the lease again and aggravate him even more as he wanted to talk to his attorney (according to what he said/presented he is a kid with rich parents with attorney), what some other ways to minimize the situation (ensuring no random security issue / damages on house and car), get my garage and driveway back, and get him to leave peacefully as soon as possible?
