There are many trainers of many topics in real estate, finance, notes, asset protection, etc.

Short-term rentals require adherence to specific ordinances, and forming an LLC offers liability protection but incurs California’s annual franchise tax.

Some sellers may not care and those that are in protected class's IE non english or simply not educated might still get taken advantage of..

My initial instinct is to wait for the results of these two efforts, as your asset protection efforts seem to depend on them.

@Charlie Martin Buying under an LLC offers liability protection and separates business finances, but it can complicate financing with higher rates and stricter terms, and lenders may still require a personal guarantee, impacting your DTI.For your first property, consider purchasing in your personal name for better loan terms and transferring it to an LLC later if needed, while using strong umbrella insurance to mitigate risk.

(We do not know if conventional rates or DSCR rates will be better for you once your rehab is completed, so best to protect both options). 

Because many have been burned over the past few years investing with sponsors who had little to no experience and investors were caught by the glamourous and sexy returns that were being promised that they were getting four years ago but are now gone from big returns to big losses.So the first question you are gonna have to answer is how do you plan on protecting investors money?
