These are all things you probably already know, so hope the viewings went well!

They've seen the peaks and valleys (08 crash and now post covid crash) and they've done unbelievably well investing there. 

I realize alot of investors have absolutely no asset protection ie LLCs for their properties and have been told by a couple of attorneys that im over thinking and perhaps paranoid of being sued, california as well as the entire US is known for excessive litigation.

Not that I got any business from it, but I really liked the young wholesalers (they were good kids that are just trying to do it the right way) that threw it as well as a few of the people that attended.

I've been thinking about ADUs as well, so I will keep that as an option.

i want to do buy and flip and buy and hold as well. 

Remodeling costs increase the property’s basis, while post-rental repairs are deductible expenses in the year incurred.An LLC isn’t necessary for a single rental but can provide liability protection as your portfolio grows.

I am an agent and own a short term rental mgmnt company so am very familiar with the STR rules and regulations as well as the best areas for that strategy locally. 

Your realtor should be the first source of guidance.For anyone here to provide you some guidance, you have to be more specific on the ask.There are always many things to consider when planning for different strategies.

I see you started your own firm as well.
