What to do with $1 million in SF Bay Area

I understand that this is a rather vague question since there are numerous variables. However, I am definitely interested in hearing some ideas, whether traditional SFR, duplexes, or even far fetched ones.

2 constants; 1) not to be a primary residence, 2) $1 million as in 300k cash and rest in loans.

Thanks in advance for your input.
