Is it worth it to house hack in San Diego in such an expensive market?

We have a property management company in San Antonio.

My name is Lonnie Perez and I'm a brand-new investor out of San Francisco.

Has anyone sold a 5+ unit ADU project in San Diego on residential zoning (RS)? 

Insurance would cover it, I would pay the deductible, and no assets would be lost.If you are in an area like San Diego where people are more likely to sue, a judge is more likely to find you guilty, and the payout is expected to be higher, you may consider an umbrella insurance policy.

Newbie here to the real estate investing world, but really eager to get my feet wet.I currently live in San Jose, but am deciding to move to a cheaper location where I can get my first property.

I do not have any 1 BR STRs/MTRs but I have seen annual STR rents based on bedroom count in both my market (San Diego) and emerald coast (one of the markets I have made offers) and the difference in the income is substantial between 2 BR and 1 BR.  

My market (San Diego) has appreciated ~10% YOY (source Core Logic).
