I have, in certain situations, agreed to early termination with what may appear to be "easy" terms for the tenant.  

Looking in the window it appears someone lives there - food on the counter, dishes in the sink, fully furnished - but nothing ever seems to move.

There is more to that story than it appears , I watched the video , thats an old trailer , pre heat pumps .

I went through 6 grades prior to leaving, and by then I'd gone through American equivalent of Algebra 2 / Geometry - I had not used a calculator...we weren't allowed!

Overall, it looks like you are answering your own question throughout your post ie. you recognise that it appears to be quite a gamble, not REALLY what you want!

People (agents, investors, bankers, etc.) do not respond kindly to people who appear uneducated.  

So, here I thought my all cash offer with a 30 day close would be a quick turnaround but now it appears we are just getting started.

Here's how investors that have worked w/ us have leveraged their Self Directed IRAsStraight Loans (equivalent of Hard money)Investment in to LLC that then invests in Real Estate (The investor was not a member of the LLC- the IRA was)Purchased the property out right in the name of the IRA (this included funds from the IRA for renovation & flip)Purchase of notes, performing & non-performingPartnered w/ their IRA- This is rather complicated but possible to do.In each case all profits went back to the IRA.  

Each persons responsibility isn't all there is to it, it's very important to have mapped out the consequences when someone doesn't hold up to there end of the bargin either partially or completely.My advice if partnering with a friend and you value the friendship make sure the partnership appears fair to both sides and they agree too.
