You just might find like minded individuals or mentors here.

I am a very motivated individual that is looking to get into Wholesaling and Fix and Flip.

For each individual property you need to find the types of people that buy that type of property in the location it's in.

The way I understand it as it's used around me, is the 'trustee' is the individual who manages the 'trust,' i.e. what a lot of people that plan their estates well will put property into in order to avoid probate, and that person has the full authority to manage and sell the property.

I've got a 4 plex that has common area for washer and dryer.No hook ups in the individual units.

I would highly recommend networking with like minded individuals who have common life goals. 

Crazy as this sounds, since the bank accepts their offer price based on their own research, 98% of FBI charges result in convictions, so anyone would be crazy to challenge them. 

With 20/20 hindsight regulators and plaintiff's attorneys paint targets on these individuals through rescission rights or other legal techniques-They train sponsors to source money through other active investors which inevitably leads to squabbling and a loss of control.  

Is it better to negotiate this for my individual unit or ask my HOA to negotiate on behalf of the entire building?

It is very hard to get these deals though as the elite contractors have built their name as the people to call when individuals want to sell their house in areas where massive rehab/upgrades can be done or that house can be razed to build a new one.
