I know that the general guidance is that emergency funds aren't to be invested, but given our financial security and the fact that we already have a personal e-fund in a safe, non-volatile location, would it still be crazy/unwise to invest this 15k in an S&P500 index fund in a brokerage? 

It may feel cumbersome, but their diligence reflects the level of security and service you can expect once onboarded.

Question is: if I have one of these LLC (owned husband and wife, in a non-community property state), but it's a just a passive LLC - such that all it does is owns public securities (ie, our brokerage accounts are titled in the name of the LLC), does the same rule apply?

With the newer 5% down conventional loan for owner-occupied multifamily option, I generally advise people to start analyzing from there if they want to house hack a multifamily with minimal down.  

The “borrower” would have an option to buy back the property if (1) all lease payments (“mortgage payments”) have been made and the borrower/seller pays is the sale price/loan amount in full at the time the option period/note matures.
