New Castle County delinquent tax list
Short answer: New Castle County has two delinquent tax lists. The official one is published by the County Finance Office before each scheduled sale, free to download, and it lists parcel numbers and amounts owed with no owner contact. The year-round one is the delinquency record underneath it, where 139 (estimated) owners near Wilmington currently carry a distress signal. Delaware is a deed state, so a winning bid at the sale takes the property itself.

Most distressed owners carry more than one signal, so these bands overlap. Stacked signals rank highest.
How New Castle compares across Delaware
New Castle County is the largest county we cover in Delaware, and it runs lighter in distressed owners than the Delaware average, at 2.4 flagged properties per 10,000 residents against a state figure of 7.5. It accounts for about 18.4% of every flagged property across the Delaware counties on this site.
| County | Seat | Flagged owners | Per 10k residents |
|---|---|---|---|
| Kent County | Dover | 457 | 25.1 |
| Sussex County | Georgetown | 159 | 6.4 |
| New Castle County (this page) | Wilmington | 139 | 2.4 |
Density matters more than the raw count when you are choosing where to work. A smaller county with a high per-capita figure often has less competition per lead than the metro next door.

Working the New Castle list
What actually matters in a county this size, at this level of distress, under Delaware timelines.
The busiest list in Delaware
New Castle County is the largest of the 3 Delaware counties covered here and carries about 18.4% of every flagged property in the state. That is the deepest pipeline available, and also the one every other buyer in Delaware already knows about.
A thin list, so filter hard
At 2.4 flagged properties per 10,000 residents, New Castle sits in the bottom quarter of Delaware counties, against a state figure of 7.5. Do not try to work every row. Sort on equity and go deep on a handful.
Wilmington and everything around it
New Castle works off Wilmington as its seat, and the scan reaches 25 miles out from there, widening to 50 when the list runs thin. In a county this shape that usually means several towns, each with its own price level.
The Delaware clock
Foreclosure here typically runs 6 to 9 months from filing to sale. The tax clock and the mortgage clock run independently, so check both before you decide how hard a deadline an owner is actually facing.
Why New Castle investors work it before auction day
No bidding war
At the sale you are one of a room full of bidders on the same parcel. Months earlier you are the only person who called.
You can see the house
A private sale means an inspection and a clean title search. Deed auctions in Delaware rarely give you either.
The owner keeps something
An owner with equity who sells early clears the tax debt and walks away with money. At the sale, they usually walk away with nothing.
New Castle County delinquent tax list FAQ
How do I get the New Castle County delinquent tax list?
Two lists exist and they are not the same. The official one comes from the County Finance Office, is published as a PDF or spreadsheet before each scheduled sale, and disappears between sales. The year-round one is the delinquency record itself, which is what LowBaller compiles: roughly 139 properties around Wilmington currently carry at least one distress signal, ranked by how much pressure the owner is under.
Is there a free New Castle delinquent property tax list PDF?
Yes. The County Finance Office publishes the pre-sale list free of charge, usually as a PDF or a downloadable spreadsheet tied to a specific sale date. It gives you parcel numbers and amounts owed. It does not give you owner contact details, an estimated value, or any indication of which owners would actually take a low cash offer.
When is the New Castle County tax sale?
New Castle County publishes its own schedule, and it moves. The Delaware pattern is the thing that holds steady: County sheriff tax sales; a short statutory redemption window applies in some counties, so verify locally. Check the county's pre-sale notice close to the date, because the list shrinks daily as owners redeem.
Can I buy New Castle tax-delinquent property before the auction?
Yes, and it is usually the better trade. There is no bidding war, the owner clears the debt with a clean sale instead of a forced one, and you are not buying blind. The window is the months between the delinquency appearing in the record and the sale being scheduled, which is exactly the period this list covers.
What does a winning bid actually get you in Delaware?
Delaware is a deed state, so a winning bidder takes the deed itself, so a winning bid transfers ownership of the property. None once the court confirms the sheriff sale. That difference matters more than the discount: in a lien state you are buying a debt with a yield, and in a deed state you are buying a house.
How far below market do New Castle deals close?
The strongest current leads near Wilmington support start bids around 43% under estimated value. Across the whole list, hard distress such as a scheduled auction or a stacked tax lien closes 25 to 45% under market, while softer signals like long-distance ownership land closer to 15 to 30% under. New Castle runs lighter in distress than the Delaware average, so the deepest discounts are rarer here and equity screening matters more than volume. Equity sets the ceiling, because an offer cannot go below what clears the owner's mortgage.
How many tax-delinquent properties are there in New Castle?
About 139 properties within 25 miles of Wilmington currently show at least one motivation signal in public records, and tax delinquency is among the most common. That works out to 2.4 flagged properties per 10,000 residents, against 7.5 across Delaware as a whole, and makes New Castle the largest of the 3 Delaware counties covered here by population. That figure moves daily as owners pay, redeem or fall further behind.
Do I need a New Castle address to search, or can I search the whole county?
Either. Run the scan on any New Castle ZIP and you get the full ranked list for the surrounding area, or check one specific address to see whether that owner carries a distress signal. Browsing is free and unlimited, and credits are only spent when an owner's verified phone or email comes back.
