There are usually a vocal minority that has the time and energy to be on the board and can push anti-investor NIMBY policies. 

Looking for advice/strategy from like-minded, anti-risk, I want to maximize cash flow type folks.

@Greg Strunak have you tried the anti-barking devices they sell online?

Guarantee you everyone would be anti-roomates if the RTP was inverse.It's not up to milennials and Gen Zers, it's up to the market.

Unfortunately It's been a constant stressor due to the anti-landlord culture and laws in the city.

Tack on the anti-landlord laws that CA is trying to pass ("Justice for Renters Act") and it just didn't make sense from an investment prospective for me.

Considering the local anti landlord laws what would be the best way to handle this to avoid any potential issues from the legal perspective?

I would determine if the new CA anti-squatter law applies (do the research now).  

The house is 100 years old and it looks like holey hell, to the point where the city starts to get involved and we (investors) get slammed in the news for running down neighborhoods generating a anti-landlord sentiment we really don't need.
