In re Deuel, 361 B.R. 509, 517 (9th Cir. BAP 2007)
          “Subrogation is a derivative right whereby one party is substituted in the place of another with reference to a lawful claim, demand, or right. Doctrine had no application as to trustee with bona fide purchaser status under § 544(a)(3), since equity favors such purchasers over one asserting equitable subrogation.
