How do we make our portfolios anti-fragile?

They are anti wholesalers.

With all the anti-landlord rhetoric and hate right now, I wouldn't risk anything during advertising or screening that gets me extra negative attention.  

That you found their "racist" remark to be immature, inflammatory, slanderous as well as devaluing of those individuals who have legitimate claims or racial discrimination. 

I would familiarize yourself with NJ's anti-eviction statute and the pertinent case law surrounding any issues regarding lease renewals, etc.

Found this place courtesy of Bogleheads.org, which is great for investing topics but too many anti-RE folks over there.

We have had huge impact due to the high response of housing providers writing their legislators and committee members, having gutted some of the worst provisions in these anti-landlord bills.  

Just like mold in a bathroom without proper ventilation, you can keep the problem at bay by wiping down the walls with an anti-mold cleaner on a regular basis.Can you break your lease and sue your Landlord?

The old landlords I bought from and my apt building buyers were simply anti-agent and like to work belly to belly.    

Not to mention the full blown corruption that is CalTrans- they are the only landlords I know of who are allowed to hike rents 10% every 6 months (their rental houses being  taken by eminent domain in Pasadena, no less).I'd say California is both anti-landlord and anti-tenant.
