Upon ongoing issues, I reached out directly to Zach who intervened almost immediately.

How does my broker intervene with my personal purchases?

If they are a reputable company, they would be forced to intervene... save face.

C) If there is anything that anyone can do to intervene in the process, buy at a discount, and sell to my end user buyer at profit.Basically, I want to hand this deal on a silver platter to whomever can navigate the nether regions of asset managers and get this thing liquidated.

Police, Social Workers, Housing all intervened...and my client dodged it all by refusing to closing until the tenant was out).  

It also hurts the creditworthiness of the bank which could lead to banking regulators intervening with the banker's portfolio of loans.

If you had to, you could file a motion to intervene and ask for the court to set the amount of redemption. 

Other than intervene once when one of them practically destroyed a joist on the second floor, I had to keep my distance, and I did.
