CH7 - at what point in the plan does the lump sum payment occur?
There is no "plan" in a Chapter 7. A Chapter 13 involves a "plan." A motion to redeem would be filed while the Chapter 7 is open.
Does CH11 allow for a plan longer than 5yrs?
Walton - this case prompted the CH7 cramdown question: In re: Mark T. Lavelle, et. al (09-72389-478, Eastern District of New York).
That case did not involve a cram down. It involved a lien strip.
removing a lien, stripping it off....essentially a cramdown right?....
No. See my original answer. A lien strip means there is no equity whatsoever, and usually refers to second mortgages on real estate, or liens that impair a Debtor's exemption.
