Mercer County tax sales, New Jersey

Verified

Mercer is the capital county. Trenton is the county seat and the state capital, and Hamilton Township is the largest municipality in the county. The six Mercer municipalities in this set show every way a New Jersey town handles its sale. Lawrence Township publishes a dated public auction. Ewing Township sells online at the end of the year. Princeton publishes a standing December pattern and no specific date. Hamilton Township authorizes an accelerated sale every year and publishes no date for it. East Windsor Township publishes a bidders packet and no date. Trenton publishes no regular sale date at all, and its dated public record is its assignment sales of the certificates it holds.

Selling office: Each municipality's tax collector (12 municipalities in the county; six of them carry pages in this set: Trenton, Hamilton Township, Ewing Township, Lawrence Township, Princeton and East Windsor Township); Mercer County runs no sale

Next sale: No county sale date exists. Next verified date in this set: Lawrence Township's public auction, Fri Nov 20, 2026, 10:00 a.m., Council Chambers, 2207 Lawrence Road (pre-registration required). Lawrence's notice is dated October 13, 2026 and states the sale is of municipal liens, not real property. Princeton's standing pattern, the second Friday in December at 10:00 a.m., is published as a pattern only; no specific December 2026 date is published.

As of November 11, 2026: Lawrence's November 20 auction is the county set's next dated sale, and it admits no one without pre-registration. Ewing's most recent sale ran online on Tuesday, December 30, 2025, and no next date is announced. Trenton's assignment program produced a June 16, 2026 assignment notice and a further notice on October 5, 2026. Hamilton's 2026 accelerated sale is authorized and undated.

Research Mercer County parcels before you bid

A sale list gives you the parcels, the date, and the opening terms. It does not give you the owner, the value, or the rest of the picture: liens, foreclosure status, and parcel history. PropertyRadar is the data platform for that layer. It carries owner records, assessed and market values, foreclosure and tax data, and property history for parcels across Mercer County, searchable by address, owner, or county, including parcels that never reach a sale list.

How New Jersey tax sales work

• Nobody at the county sells anything. Under NJSA 54:5-19 the tax collector of each municipality sells. Counties in New Jersey assess nothing for this process and run no sale; every date, list, platform and deposit rule on these pages belongs to a town, not to the county named at the top.
• What is sold is a certificate, a lien, not the property. The Division of Local Government Services states it plainly: at the tax sale, title to the delinquent property itself is not sold; what is sold is a tax sale certificate. The owner keeps the property and is not evicted.
• Two sale tracks run on the statute's calendar. A standard sale is held in the fiscal year following the year of delinquency. An accelerated sale reaches charges in arrears on the 11th day of the eleventh month of the fiscal year, conducted no earlier than the last month of that year, which is why December accelerated sales exist. A municipality may run both.
• Bidding is the rate down from eighteen percent, then premium. Under 54:5-32 the lien is struck off to whoever takes the lowest rate of interest, never above 18 percent. When a bidder offers less than 1 percent or no interest, premium bidding takes over: the winner pays the amount due plus the highest premium. The premium goes to the municipality, earns no interest, is returned if the owner redeems, and escheats to the municipality if the certificate is neither redeemed nor foreclosed within five years.
• Redemption runs through the collector until a court bars it. The owner, heirs, a prior certificate holder, a mortgagee or an occupant may redeem at any time until the right is barred by a Superior Court judgment (54:5-54, 54:5-86), paying the sale amount with interest at the bid rate, the holder's subsequent lien payments and expenses, and the tiered penalty in 54:5-61: 2 percent over 200 dollars, 4 percent over 5,000, 6 percent over 10,000.
• Foreclosure has two clocks, and assignment moves you to the faster one. A private holder may file in Superior Court after two years from the sale; a municipality, or its assignee or transferee, may file after six months (54:5-86), and a municipality may proceed in rem where six months have run and 21 months of general land taxes remain unpaid (54:5-104.32, 54:5-104.34). Since July 10, 2024, P.L.2024, c.39 has revised the process so an owner can protect remaining equity, so foreclosure is no longer the automatic equity transfer older guides describe.
• Unsold liens are struck off to the municipality at eighteen percent. The municipality may later sell those certificates by private assignment under 54:5-113, for not less than the liens by governing body resolution, or at public sale under 54:5-114.1 and 54:5-114.2, the second permitting sales below the amount due. That assignment market is New Jersey's leftover channel, and it is municipal, never county run.

How buying works in Mercer County

Registration in Mercer is a Lawrence Township rule and an Ewing Township website. Lawrence requires pre-registration and admits no one without it; its notice publishes no registration deadline or channel beyond that rule. Ewing registers bidders at its online sale site. Princeton, Trenton, Hamilton and East Windsor publish no registration terms in the sources read.

• The rate is a giveaway on any lien worth having. On contested certificates the interest rate is bid to zero in the first minutes and the real bidding is the premium, which earns nothing and sits with the municipality for up to five years. The disciplined New Jersey bid is therefore set entirely by the property and the foreclosure timeline, never by the rate, and any model that shows yield on a premium dollar is wrong on its face.
• In Mercer, the assignment channel is a front door. Trenton and Hamilton both sell certificates they already hold, by published notice and governing body resolution. An assigned certificate carries the municipality's six month foreclosure clock from the original sale date, so in this county the leftover channel is not a remainder bin. It is a dated, documented way in, and the notices and agendas are its calendar.

Terms: what a bid actually costs

The leftover channel: struck off certificates and municipal assignment

Mercer is the county in this set where the leftover channel runs in the open. Trenton assigns the certificates it holds under 54:5-113 on published notice, most recently proposing assignment on June 16, 2026, with a further notice posted October 5, 2026. Hamilton Township assigns municipally held certificates under 54:5-114.2(1)(b) by governing body resolution, four certificates authorized on January 20, 2026 and three further resolutions recorded November 10, 2025. An assignee inherits the six month municipal foreclosure clock under 54:5-86 from the original sale date.

Before you bid

• Start with the town, because there is no county list. Every fact that matters, the date, the list, the platform, the deposit, lives with one municipal tax collector. The county page tells you which towns publish and what they published; the towns that publish nothing are a telephone call, and no website, this one included, can substitute for it.
• Redeem and pay only through the collector. Redemption money goes to the tax collector for the holder's use, and the collector's figure is the redemption figure. Never pay a certificate holder directly on their own number, and record your certificate with the county clerk within 90 days of the sale to protect the lien.
• Know which clock your seller gives you. A certificate bought at the sale carries a two year wait before foreclosure; the same certificate bought by assignment from the municipality can be foreclosed on the six month municipal clock from the original sale date. The channel you buy through is a term of the deal, priced like one.
• Set the maximum before the sale opens. The free Max-Bid Calculator below works backwards from your exit value to the highest bid you can pay, with the costs shown. In premium territory the maximum is a property decision, not a yield decision.
