Thank you for the key missing fact in this deal. I don't know why it is that folks who try to explain this deal cannot distill it down to the essential facts - all the essential facts. The essential fact is that the seller could give 0 a $300k discount on the house because he was getting a $385k premium on the lot next door from Rezko. It is the most important point in the whole transaction - and the one that is never stated.
