Notes

Mercer municipalities (Trenton, Hamilton, Ewing, Princeton, Lawrence, Hopewell, etc.) each conduct annual tax sales under N.J.S.A. 54:5 for taxes and municipal charges. Bid-down from 18%; premium at 0%. Certificate holders earn statutory interest; foreclosure of right of redemption is a Superior Court action typically after 2 years for third-party certificates. Trenton historically runs a large December tax sale. Use Mercer County Board of Taxation collector directory for each town's collector and sale notice.

Title risk

Liens that survive the sale

Certificate is lien not ownership. Federal liens, water/sewer, and special charges need review. No possession until foreclosure judgment.

Quiet title

Superior Court foreclosure of the tax certificate is the ownership path; quiet title alone does not replace foreclosure judgment.
