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

Since your tenant has only been there a 2-3 months, the actual tenant turn expenses could remain fairly low if handled well.

But I suspect, regardless, the mid-term market is not a place for adding expensive amenities; those folks are typically on a strict budget and staying long term; the budget and often, proximity to the purpose for their visit drives booking decisions.

I'm hearing stuff like you have to pay relocation costs based on # of years they have lived there or some expenses I think are absolutely crazy.

On average, 80 people move into Columbus weekly.

I was thinking of getting one for my property's LLC and then adding myself as an employee with a separate card, cancel my card I have for personal use, and expense the annual fee for the business card.If I have a business card as an employee, what are your thoughts on using that "employee" card for my personal expenses so I can track them and pay them separately.  

Im moving to San Diego next year and want to buy a house hack but its insanely expensive.

My knowledge is limited and there are obviously variables in location, size of units, amenities, expenses, TI, etc.

My gross monthly average since November is about $3k per month, and my net outside of my mortgage is about $2k per month.

Interest rates are not going down anytime soon, and your expenses are going to continue to increase as well as your taxes and insurance.
