SUMMARY ORDER UPON DUE CONSIDERATION, IT IS HEREBY ORDERED, ADJUDGED, AND DECREED that the judgment is AFFIRMED. Appellant Swinton Brown appeals from the June 16, 2014, judgment of the United States District Court for the Eastern District of New York dismissing his claims challenging a state court foreclosure judgment against his property. We assume the parties’ familiarity with the underlying facts, procedural history of the case, and issues on appeal. We review a dismissal under the Rooker-Feldman doctrine de novo. Green v. Mattingly, 585 F.3d 97, 101 (2d Cir.2009).
A claim is barred under the Rooker-Feldman doctrine when a federal-court plaintiff who lost in state court complains of injuries caused by a state-court judgment rendered before the federal proceedings commenced, and invites the district court’s review and rejection of that judgment. Exxon Mobil Corp. v. Saudi Basic Indus. Corp., 544 U.S. 280, 284, 125 S.Ct. 1517, 161 L.Ed.2d 454 (2005); Green, 585 F.3d at 101. The district court properly found that the Rooker-Feldman doctrine applied:
(1) Brown is challenging a state foreclosure judgment; (2) the alleged injuries stemmed from that judgment (loss of property based on fraud);
(3) Brown sought review and rejection of the state court’s foreclosure judgment; and (4) the district court complaint was filed after the state court’s judgment. See e.g., Green, 585 F.3d at 101. To the extent that Brown requests the federal court to return his property to him because the foreclosure judgment was obtained fraudulently, Rooker-Feldman bars his claim. See Vossbrinck v. Accredited Home Lenders, Inc., 773 F.3d 423, 427 (2d Cir.2014) (determining that Rooker-Feldman barred federal court suit that sought to regain title to property based on allegation that foreclosure was obtained fraudulently).
Finally, Brown’s challenge that the district court improperly ignored defendants’ motion to dismiss pursuant to Federal Rule of Civil Procedure 12(b)(6) fails; the district court had an obligation to determine subject matter jurisdiction before considering the 12(b)(6) arguments. See United States v. Bond, 762 F.3d 255, 263 (2d Cir.2014) (“Subject matter jurisdiction is a threshold question that must be resolved ... before proceeding to the merits.”) (internal quotation marks omitted, alteration in the original). We have considered the remainder of Brown’s claims and find that they are without merit.
Accordingly, we AFFIRM the judgment of the district court.
