Although Chapter 20 cases are permitted, TD Bank and the Trustee encourage this Court to adopt a per se rule making lien stripping in a Chapter 20 case contingent upon the entry of a Chapter 13 discharge. A general review of lien stripping is instructive. “In a ‘strip off the entire lien is removed, whereas in a ‘strip down’ a lien is bifurcated into secured and unsecured claims with only the unsecured claim component being removed.’ ” Johnson v. Asset Management Group, LLC, 226 B.R. 364, 365 n. 3 (D.Md.1998) (citing In re Lam, 211 B.R. 36, 37 n. 2 (9th Cir. BAP 1997)). It is well established that a debtor is precluded from lien stripping in Chapter 7 cases. See Dewsnup v. Timm, 502 U.S. 410, 112 S.Ct. 773, 116 L.Ed.2d 903 (1992) (<HOLDING>); see also Ryan v.
