MEMORANDUM **

R & S St. Rose Lenders appeals from the district court’s order reversing in part an order by the bankruptcy court that overruled Branch Banking and Trust’s objection to Lenders’ proof of claim in the bankruptcy of R & S St. Rose. The district court’s order remanded the matter to the bankruptcy court for further proceedings. We review de novo our own jurisdiction and whether a bankruptcy court’s decision is final under 28 U.S.C. § 158(d). Silver Sage Partners, Ltd. v. City of Desert Hot Springs (In re City of Desert Hot Springs), 339 F.3d 782, 787 (9th Cir. 2003). We dismiss for lack of jurisdiction.

The district court’s order reversing the bankruptcy court and remanding for further proceedings is not a final decision over which we have appellate jurisdiction. See Sahagun v. Landmark Fence Co. (In re Landmark Fence Co.), 801 F.3d 1099, 11Ó2-03 (9th Cir. 2015) (discussing the standard for determining finality in bankruptcy proceedings). The district court’s order opens the door to further factfinding and litigation surrounding the amount of Lenders’ proof of claim. This court’s interest in avoiding piecemeal litigation, promoting judicial efficiency, and preserving the bankruptcy court’s role as factfinder all therefore weigh against a finding of jurisdiction. See id. at 1102-04.

Each party is to bear its own costs.

DISMISSED.
