He is talking about using a technique to what was known in the note world as "Simultaneous Closing" or "Table Funding".  

What kind of cash would I need to bring to the table? 

More partners you bring to the table - less money you make.

Not enough equity capture if I am the one bringing the money to the table.

I realize that this is how the industry operates and they pay out based on mortality tables etc... but the family feels they were treated unfairly. 

Simple fixes; get rid of the shrubs, add shutters, some flowering plants, some kind of decoration over the garage door - those big stars seem to be popular in suburban areas, one or two patio chairs and a small table on the porch, simple stuff like that can make a big difference.

Yes you leave a lot of money on the table, but you build up your cash reserves in the meanwhile and then you will have the capital you need to fund your bigger projects.Best of wishes!

Thanks for the input @charmine I have been asked to speak and or present a table at the NYC real Estate expo this year maybe we will see each other there.

What forms do I need to have completed in order to sell my land, before I get to the closing table with an attorney. 

Draw up an MOU outlining the details of duties of each partner as well as return, then once agreed upon proceed to a JV, LLC, or other.This may be general but this will hopefully help influence you before making a final commitment.Lay everything on the table.
