Directs Fannie Mae, Freddie Mac, and Ginnie Mae to require all their current MERS mortgages to be assigned to the proper servicer, holder, or creditor.

Directs the Secretary of Housing and Urban Development (HUD) to study: (1) the impacts of the lack of electronic records and uniform standards found in local land title recordation systems currently used in the various states; (2) any progress states have made in developing electronic land title recordation systems containing uniform standards; (3) the current oversight role of the federal government in the transfer and recordation of land titles; and (4) the feasibility of creating a federal land title recordation system for property transfers that would maintain all previous records of the land-property without invalidating, interfering with, or preempting state real property law governing the transfer and perfection of land title.
