You apparently did not read the terms of joining this forum. Let me reprint part as a reminder:
Please read carefully. This is not the usual yada, yada stuff.
This site is not intended to give legal advice...
You are asking for some very specific legal advice on a very complicated subject. Do you really think we want the exposure to a professional liability claim because you apparently are not willing to pay for some advice? We can only discuss things in general terms, like "What is a bond for deed contract?"
As for your assertion that you want someone well educated but not an attorney to discuss the bond for deed concept, history going back to 1979, and present status as it relates to your complicated situation, then good luck with that!
