I'm new here, and am ready to start investing my time into learning the strategies to get my first rental in 3 months.

Consulting a tax professional now can help structure ownership and financing efficiently, ensuring you take full advantage of deductions, depreciation, and potential tax-saving strategies like 1031 exchanges in the future.This post does not create a CPA-Client relationship.

Buying a second home to rent out is a solid strategy, but be sure you understand the cash flow, including mortgage, taxes, and potential vacancies.

The goals will determine the strategy (what you do) and the tactics (how you do it).

With the right strategy, it can become the foundation for building wealth.

I personally would revisit your strategy of buying a negative cash flow property in SoCal, right now.

Well worth it and the best strategy to start in my opinion. 

I did it a few times and used Section 8 as part of my strategy.

And do they care if I do rent by the room strategies?

Depends on strategy and long term goals with REI.
