@Franklin Marte, no harm in trying.

I can't recall the name, but it smells like vinegar and is not harmful to people or animals.

Gotterdammerung: A Very Serious Legal Threat.It alleges that cooperation and compensation is an anti-trust violation that results in consumer harm, and seeks an injunction against forcing home sellers to pay the commissions of the buyer agent.https://notorious-rob.com/2019/03/gotterdammerung-a-very-serious-legal-threat/

this guy has major liability in my mind.. not only Notary fraud.. but clouding title and causing harm to the seller. 

No harm is ever going to come from visiting the market.

Rather than try to fight the way things work (everything has downsides and you can't protect people from every possible harm that may come there way), use "the system" to make a profit for yourself, and give back where you feel it will do the most good (and there is never enough, there never will be).For instance, in this case it might mean making as much as you possibly can (in an ethical manner) and steering a percentage of those profits into something that helps what you feel about.Now you might say that's sideways logic, but really, you can't stop the way things work (they work that way for a reason that generally involves the greater good in some way, such as preventing slums) and those who would benefit from the percentage donation (even if it's not tax deductible, such as a homeless shelter) would never get that money if you had not made a profit.

A great tenant who has run into a tough situation temporarily what’s the harm in working with them.  

Certainly, don't accept any payment before you get to court, but I can't see the harm in responding.

They declared bankruptcy, yet that shouldn't harm the condos much as the association doesn't really have to rely on credit. 

Plus, if the profit of your other properties can float that cost + the maintenance for 7 years, then what is the true harm?
