I got several hits, and chose to go with someone who established themselves as a cash buyer who could close within 2 weeks.  

Not only will my established and establishing connections help me in the field, but continuously working with both of these types of businesses will help me gain a better understanding of their specific financial statements and tax opportunities/implications.

My goals in real estate are to own rental property and to be able to establish a positive cash flow from these investments.

Yet establishing a 'trusting relationship' for long-term projects must be earned and its going to take time.

@Jeff Meachen It will likely take months to establish the executor of the estate and for it to be ready to legally sell.  

Establish Lead Generation systems that are working 24/7.  

I don't understand you comment.Partnerships can be established as long as both partners agree to the terms ahead of time.  

Could they just buy a share of the company that paid a set dividend under pre-established terms?  

Not only can you get started in wholesaling with just a minimal cash outlay, wholesaling also offers a valuable introduction to real estate investing fundamentals such as running comparables, determining if a deal is good or not, establishing ARVs, and estimating renovation costs.  

What are some good follow up questions to help establish the value of the property?
