My current focus - what is the process once a family member/individual has passed and lets just say in a perfect world probate has been filed and the respective family is now thinking about selling the property.

Not only would you benefit from having a partner's input on the deal, but you would also have an experienced individual to work alongside with as you navigate the project.It's also important to make sure you have identified your "team" ie; contractors / realtors / lenders / insurance agents / title company / etc. 

We are both highly dedicated and ambitious individuals with a strong desire for personal and professional growth.

According to the brokerage and agent, these individuals either weren’t serious or claimed they didn’t realize the property was occupied, even though it was clearly stated in the listing.I’m not particularly concerned about the property’s condition or the eviction process, as I’ve already secured some level of cooperation and have basic access to the basement.

If I was the owner I would be asking why is it not published in the NY times, or other publications that have high net worth individuals.

For existing companies, individuals who own at least 25% of the entity or exercise substantial control over it must submit BOIR to the Financial Crimes Enforcement Network (FinCEN) by December 31, 2024.

Some places like Illinois for example require individuals to be licensed with the state in order to wholesale more than 1 deal per year. 

I can see things moving forward in two ways: 1) These individuals and entities will work with us to return monies owed back to the Company or 2) we will need to go to litigation.

If I were to go this route I would clearly identify each of these risks individually, understand how the Govt would potentially challenge each of them and then assess in your particular fact pattern how you would effectively rebut a challenge to each.
