Notes

New Jersey tax lien sales are MUNICIPAL, not county-run. Warren County municipalities (Phillipsburg, Washington Borough/Township, Hackettstown, Belvidere, Blairstown, etc.) each hold at least one annual tax sale under N.J.S.A. 54:5. Many use RealAuction (newjerseytaxsale.com) or in-person sales; schedule and platform vary by tax collector. Investor receives a tax sale certificate and must foreclose via Superior Court to obtain title (typically after 2 years). County Board of Taxation / Clerk support records research but do not sell countywide liens.
