The 'NOTICE' letter appears to be addressed to the occupants of the home and assumes the property to be "vacant and/or abandoned". This letter is tapped to the front door of the property AFTER a 'judgment' and 'writ of possession' is issue in what appears to be a 'foreclosure case' (including 'eviction cases') and the occupants of the home are forced to vacate the property by the local de facto Sheriff's Department.
This process appears to be a foreclosure or eviction / unlawful detainer, and comes under the feudal process called "escheat" (the reversion of property (real estate) to the STATE in consequence of a lack of any individual competent to inherit and make claim thereto); and whomever is claiming to be the alleged 'holder in due course' of the 'mortgage note' or 'foreclosure sale' is called the "feoffer" (feudal word for "trustee"; the person making a feoffment / fee simple deed, or enfeoffing another in fee).
The "feoffment", being the 'deed' and 'deed of trust' instrument you signed as the alleged buyer during the "settlement and closing process", is defined as "the gift of any 'corporeal hereditament' (substantial permanent objects which may be inherited. The term "land" will include all such) to another, operating by transmutation of possession. Also, the grant of a feud or fee, i.e. the 'Deed' and 'Deed of Trust' instruments. Therefore, when you sign and consent to the 'Deed' and 'Deed of Trust/Mortgage' instrument you "Gift" your inherited birth-rights to the property-estate over to the 'Trustee' (feoffer) cited in the 'Deed of Trust/Mortgage' or to the alleged 'Substitute Trustee' (third-party interloper) by the process of abandonment.
This is the deceptive method used by the men and women acting de facto as Presidents / Chief Executive Officers, attorneys, and representatives of these foreign corporate financial institutions styled as "Banks", "Mortgage Companies", and "Courts". All of their collusive actions and methods come under what is called 'color of law', 'color of authority' and 'color of office' within purview of the unconstitutional 14th Amendment U.S. corporate citizenship and constitute 'inducement to fraud'!
