New Jersey tax lien investing pays a statutory rate that can reach roughly 17%, but almost nobody actually earns that number. The auction runs in two stages — bidders first drive the interest rate down, sometimes all the way to zero, then start stacking a cash premium on top of the lien amount that earns no interest whatsoever. Your real return is decided before you ever collect a dollar.
Zhanna Kelley, a New York broker and CPA who buys liens in New Jersey and deeds in Florida, has bid at live county auctions in Passaic County and blind online sales. She estimates only 3 to 5% of liens end in foreclosure, which means in the overwhelming majority of cases you are an interest lender, not a buyer.
This guide covers how the two-stage bid actually prices a lien, what your yield looks like after the premium, how to select liens based on whether you want interest or the house, what a tax lien foreclosure wipes out, and the paperwork burden that catches new buyers.
Key takeaways
- New Jersey auctions bid the interest rate down first — starting around 14% and potentially reaching zero — before bidders begin bidding a cash premium on top of the lien amount.
- Premium earns no interest at all. On a $5,000 lien bid up to $7,000, that $2,000 spread is dead money you only recover if and when the owner redeems.
- Roughly 3 to 5% of tax liens end in foreclosure. Plan to be an interest lender first and a property owner only occasionally.
- Small delinquencies — a $500 tax bill, for example — almost always get redeemed. If you want the property, look for deceased owners with no apparent heirs and no clear line of succession.
- Foreclosing a tax lien wipes out underlying mortgages and HOA dues, though certain county and environmental-type liens can survive. Verify priority in your specific county before bidding.

How a New Jersey Tax Lien Actually Works
New Jersey is a lien state, not a deed state. When an owner stops paying property taxes, the county still needs that revenue to fund services, so it sells the delinquency rather than the property. You are buying the right to pay someone else’s tax bill and collect it back with interest.
Kelley describes the cycle plainly: the owner falls behind, the county posts the available liens once a year, you bid, and you win the right to pay the taxes on that owner’s behalf. Then you keep paying them for roughly two more years. If the owner never repays you with the statutory interest attached, you can move to foreclose on the property.
In her New Jersey counties the sale lands in the fall, which she notes is conveniently after tax season. The statutory rate she cites for New Jersey is around 17%. That is the ceiling, not the outcome — see the next section for why.
Two caveats before you go shopping. First, the lien can be redeemed at any point during the hold, so your capital comes back on the owner’s schedule, not yours. Second, none of this is uniform. Some states sell liens, others sell deeds, and the mechanics differ county to county. Kelley only operates in New Jersey and Florida and is explicit that she cannot speak to every state. Read your target county’s rules before you commit money.
The Two-Stage Bid: Rate Down, Then Premium Up
This is the mechanic that decides your return, and most introductory material skips it entirely. A New Jersey lien auction does not price on one variable — it prices on two, in sequence.
Stage one: the rate gets bid down. At the live auctions Kelley has attended, including one in Passaic County, bidding opens around 14% and competitors bid the rate downward. It can go all the way to zero. Whoever accepts the lowest interest rate wins that stage.
Stage two: the premium gets bid up. Once the rate hits bottom, bidders start offering cash above the lien amount. Kelley’s worked example: a lien with $5,000 of delinquent taxes gets bid to $7,000. That $2,000 difference is premium, and it earns no interest at all. You paid it purely to win.
She has watched a single institutional buyer walk out of one of these sales with 30 or 40 liens. These are not hobbyists — they are participants who have priced the redemption math and are comfortable being lenders.
Online sales work differently and are arguably more dangerous. Kelley describes them as blind: you submit your number without seeing what anyone else bid. On a $5,000 lien you might enter $5,000, $5,500, or more, with no feedback. The structure creates a built-in incentive to overbid, because the only way to be confident you win is to pay more than you think you need to.
Let’s say you bid $7,000 and win it. That $2,000 difference is actually a premium that you don’t get absolutely any interest on. It’s just to win that deed.

What Your Real Return Looks Like After the Premium
The headline statutory rate is a starting point in an auction, not a yield you are quoted. By the time a competitive lien clears, the rate has been bid down and a premium has been stacked on top — and that premium earns nothing.
Run the logic on Kelley’s example. You put $7,000 out to acquire a $5,000 lien. Whatever interest rate survived the bid-down applies only to the tax amount you actually advance. The $2,000 premium sits there earning zero for however long the redemption takes, and you only recover it at all when the lien is redeemed. Both stages of the auction compress your return, and they compress it in different ways: bid-down cuts the rate, premium dilutes the base.
Now layer in the redemption reality. Kelley cites statistics putting roughly 3 to 5% of all tax liens as ending in foreclosure. The other 95%-plus redeem. That means the realistic outcome you should underwrite for is interest income on a multi-year hold, not a property acquisition.
She frames the comparison as still favorable — the interest is very high compared with what a CD pays, which is precisely why institutional buyers show up and buy in volume. But favorable relative to a CD is a different claim than 17%. Model the return on what you actually pay in, at the rate you actually won, over the time you actually expect to wait. If a lien only pencils at the statutory rate with no premium, you should not be bidding on it.
Selecting Liens: Redeemers vs. Properties You Might Actually Own
Lien selection, not bidding tactics, determines which outcome you get. Before you bid, decide whether you want interest or you want the house, because the two profiles look completely different on the county list.
If you want interest, small delinquencies are the reliable play. Kelley uses $500 as her example: a homeowner who is behind by a few hundred dollars is almost certainly going to pay it. Someone with equity and the means to cure a small bill does not walk away from a house over it. You make a few dollars in interest and you will not win the property.
If you want the property, the filter changes. Kelley specifically looks for owners who are deceased and appear to have no family, because there is no clear line of succession. Nobody is monitoring the tax bill, nobody is going to redeem, and foreclosure becomes plausible rather than theoretical. That research happens before the bid, not after.
The counterweight is real: you can win a property you do not want. Kelley is direct about this and points to well-known cautionary cases in the tax lien world. Her diligence sequence before bidding:
- Drive the property and look at it physically
- Know the neighborhood, not just the parcel
- Research the owner and the property online
- Bid only in counties you already understand
The upside justifies the work. Winning a property for $5,000 to $15,000 that is worth $200,000 or $300,000 is why the strategy exists. But that math only holds if the property is actually worth taking title to.
Foreclosure Cleanup: What Gets Wiped and What Survives
When you foreclose on a New Jersey tax lien, the underlying debt largely disappears. Kelley’s account: mortgages are wiped out, HOA dues are wiped out, and you emerge as the owner. A handful of items — certain county liens and environmental or DEP-type obligations — can potentially survive, and those tend to be large enough that they matter. Confirm what attaches in your county before you assume a clean slate.
The reason this works is priority position. Property taxes sit at the top. Everything junior to them gets cut off when the tax lien forecloses.
Kelley has seen the same principle from the losing side. She serves as head of an HOA that periodically forecloses on units for unpaid dues, and dues sit near the bottom of the priority order. When the association takes title, the mortgage remains, the taxes remain, and the association owns something it cannot offload.
You have the place, but it’s laden with so much debt that it’s unworthy, so to speak.
One of those HOA foreclosures involved a unit occupied by a resident with four cats and no running water, using a bucket in the kitchen. The association evicted her and then owned a property with negative value and a rehab problem attached.
The lesson transfers directly. The same foreclosure action, filed from a senior position, hands you a property free of mortgage debt; filed from a junior position, it hands you a liability. Before you buy any lien, know exactly where it ranks and what ranks above it.
The Paperwork and Time Burden Most Buyers Underestimate
Winning the lien is the start of a multi-year administrative job. Kelley is blunt that this is the part that trips people up: you have to be on top of your game in terms of paperwork.
What the hold actually requires:
- Continuing to pay the property taxes quarterly on the owner’s behalf
- Filing notarized affidavits documenting those payments
- Tracking every advance across a hold that can run two years or more
- Being ready for redemption at any moment, which ends the position on the owner’s timing
Miss a step and you can compromise your position on a lien you have already funded. This is bookkeeping-grade discipline, and it is worth noting that Kelley is a CPA — the record-keeping comes naturally to her in a way it may not for you.
Her decision to do less tax deed work in Florida is instructive about scoping. Deeds cost considerably more than liens because you are buying the property outright at the sale. The treatment of existing mortgages is more complicated, and what survives closing is less predictable. Large counties like Miami-Dade run these sales several times a year with thousands of parcels, which is volume you cannot evaluate remotely. Her read is that you need to be physically present and active in that market to do it well, and since she is not in Florida full time, she mostly does not.
That leads to the operating rule worth taking from all of this: work only counties you already know. Familiarity with the neighborhoods, the tax collector’s office, and the local rules is what separates a priced bid from a guess.
Frequently asked questions
If I bid the interest rate down to zero and pay a premium, how do I make any money on a tax lien?
At that point you largely don’t — which is why the two-stage auction is a trap for undisciplined bidders. If the rate is bid to zero and you also pay a premium above the lien amount, you have advanced capital with no interest accruing and a premium that earns nothing and only returns on redemption.
Buyers who bid that aggressively are typically pricing in the small chance of taking title to the property. Set a maximum before the sale based on the return you need at the rate you’d actually win, and stop bidding there.
How often does a tax lien actually end in you owning the property?
Roughly 3 to 5% of the time, according to statistics Zhanna Kelley cites from her New Jersey experience. The other 95%-plus of liens get redeemed by the owner, meaning you collect your advance plus whatever interest rate survived the bid-down.
Underwrite accordingly. Treat foreclosure as an occasional bonus outcome rather than the plan, unless you have specifically selected liens where redemption looks unlikely.
Does foreclosing on a tax lien wipe out the existing mortgage?
In New Jersey, yes — foreclosing on a tax lien wipes out underlying mortgages and HOA dues, because property taxes hold senior priority. That is the core reason the strategy can produce a property worth far more than the lien cost.
Certain county liens and environmental or DEP-type obligations can potentially survive. Rules vary by state and county, so confirm what attaches with local counsel before assuming clear title.
Why does buying a lien on a small $500 tax delinquency rarely get you the house?
Because an owner with equity and any financial capacity will pay a $500 bill rather than lose the property. Small delinquencies are the most likely to redeem, which makes them an interest play, not an acquisition play.
If your goal is title, look instead for situations where nobody is positioned to cure the bill — Kelley targets deceased owners with no apparent family and no clear line of succession.
What ongoing obligations do I have after winning a tax lien at auction?
You keep paying the property taxes on the owner’s behalf, typically quarterly, for roughly two more years, and you file notarized affidavits documenting those payments. Each advance adds to what the owner must repay you.
The administrative side is genuinely demanding across a multi-year hold. If your record-keeping is loose, fix that before you buy your first lien.
The bottom line
Before your next New Jersey sale, write down the maximum total you’ll pay for each lien on your list — lien amount plus premium — based on the interest you’d earn at the rate you realistically expect to win, and treat that number as fixed once bidding starts.
