Angela Brock borrowed $544,000 and signed a note payable to Amerifund Mortgage Services, LLC, to buy a house in Silver Spring, Maryland. The note was endorsed in blank and transferred several times "without recourse" before Brock fell behind on the payments. On behalf of Deutsche Bank National Trust Co., BAC Home Loans Servicing LP initiated foreclosure. Brock filed an action in a Maryland state court to block it, arguing that BAC could not foreclose because Deutsche Bank, not BAC, owned the note. Can BAC enforce the note? Explain why or why not
