The federal statute of limitations applicable to actions by the Federal Housing Finance Agency sets the limitations period at 6 years for contract actions and 3 years for tort actions.  12 U.S.C. § 4617(b)(12)(A).  This decision holds that the same limitations provisions apply to assignees of instruments once owned by Fannie Mae or Freddie Mac, the housing finance isntitutions that are under FHFA conservatorship.  It also holds that at least when the assignee’s claim to title is based on a deed of trust or mortgage, a quiet title action arises from that contract and is thus a contractt action for purposes of the cited section.  Moreover, when there is a doubt about which federal limitations statute applies, the doubt is resolved in favor of the longer statute.
