Sell your house fast in New Castle, DE
From an eighteenth-century house a block from the green to a 1950s ranch off Basin Road, we buy New Castle homes in whatever state they are in. Expect a cash offer, usually within a day, and a settlement, run by a Delaware lawyer, on a day you pick.
First: are you in the city, or just the mailing address?
“New Castle, DE” covers two different things. The City of New Castle is a small incorporated city on the Delaware River with its own government, its own tax bill and its own historic district rules. The New Castle mailing address, though, stretches far beyond the city limits into unincorporated neighborhoods that New Castle County governs directly. If you are not sure which you are, your tax bills will tell you: a city property has a bill from City Hall on Delaware Street as well as the county bill.
This page focuses on the city, with a section at the end for the wider mailing area. Either way, we can make an offer. Northbound Home Buyers is based in Swedesboro, New Jersey, on the New Jersey side of the Delaware Memorial Bridge, a few miles from town. We do not have a Delaware office; we drive over for the walk-through and settle through a Delaware attorney.

The City of New Castle in numbers
- 5,551residents in the 2020 census; 5,726 in the July 2025 estimate
- 63.4%owner-occupied rate, Census QuickFacts 2020–2024
- 22.9%of residents are 65 or older (Census QuickFacts)
- 1732year the New Castle Court House was built, now part of a national park
The city is small, about 5,600 people, and older than most of the country. The New Castle Court House on Delaware Street went up in 1732 and served as Delaware’s first court house and later its capitol; today the National Park Service runs it as part of First State National Historical Park. The historic district around it, which reaches from the river back to roughly Sixth Street, was named a National Historic Landmark in 1967.
Outside that core the housing changes quickly: early twentieth-century homes, postwar blocks of brick and frame singles, and newer infill. Nearly a quarter of residents are 65 or older, so a lot of the homes that reach us have been in one family’s hands for decades. That usually means sound bones with dated systems: old service panels, original windows, aging boilers, and kitchens and baths last remodeled long ago.
Why New Castle owners call
A historic house that needs work. Inside the historic district, exterior changes need approval from the Historic Area Commission before you can even pull a building permit. That adds time and cost to every repair a buyer might demand. We buy without asking for any of it.
A move to something easier. Stairs, upkeep and a big yard become harder to manage. Selling as-is means no contractors, no showings and no rush to empty the house.
An estate. Heirs dealing with a parent’s home, probated in Wilmington, often want one clean sale and one check to divide.
Water. A house that has taken on water, or an owner tired of flood insurance premiums, sometimes prefers to hand the problem to a buyer who expects it.

City and county offices for a New Castle sale
City business happens within a few blocks of the green. County business is split between Reads Way, just outside town, and the City/County Building in Wilmington.
| Task | Where | Why a seller cares |
|---|---|---|
| City taxes | City Finance, City Hall, 220 Delaware Street, (302) 322-9804 | The city’s own annual bill, with a discount for paying early and a penalty for paying late. |
| Water and electric | Municipal Services Commission, 216 Chestnut Street, (302) 323-2330 | You file a disconnection form and the buyer applies for a transfer of service. |
| Historic district approvals | Historic Area Commission, through the Building Department, 322-9813 | Exterior work in the district needs a Historic Review Certificate before a permit. |
| Code and rental licenses | Building and Zoning, (302) 322-9813 | Violation notices, inspections and the city’s Rental Housing Business License. |
| County and school taxes | County Office of Finance, 87 Reads Way, (302) 395-5340 | The second bill, which includes the Colonial School District’s tax. |

Taxes inside the city line
City penalty date: October 1City of New Castle tax bills go out in mid-July. Pay by August 31 and you get a 2 percent discount; anything still unpaid on October 1 picks up a 6 percent penalty, then another 1 percent interest for each month after October.
City owners also receive the New Castle County bill for county and school taxes. This year that one runs on a different clock: the General Assembly moved it to a November mailing and a December 31, 2026 due date. So an owner who is behind may owe two governments with two sets of penalties, and the settlement attorney will ask both for payoff figures. Our back taxes guide explains how that money comes out of the sale.
The county’s transfer tax sheet lists New Castle City among the places where the Recorder of Deeds collects the local share along with the state’s, paid by two checks at recording. Delaware law splits the total evenly between seller and buyer, and the attorney’s statement shows each piece. On a sale to us, the seller and Northbound each pay half.
Historic rules, rentals and code
The Historic Area Commission. In the district, nearly anything visible needs the commission’s approval first: building, altering, adding to, moving or tearing down a structure, and even signs. A Historic Review Certificate is required on top of the ordinary building permit, and the commission meets once a month, on the second Thursday at 6:30 p.m. For a seller, that means a buyer’s repair request can take weeks to satisfy properly. We purchase first, without that work, and seek the approvals ourselves later.
Rentals. A landlord with residential units inside the city needs a Rental Housing Business License from the city. If you would rather stop renting, our page for tired landlords covers selling with a tenant in place.
Code. The city’s Building and Zoning office, run by the Building Official who is also the Fire Marshal, checks code compliance and sends violation notices. An open notice does not stop a sale to us. See code violations for how it is handled.
Living behind the dikes
New Castle sits low on the Delaware River and has been protected for centuries by earthen dikes. DNREC counts four in and near the city, the Buttonwood, Broad, Gambacorta Marsh and Army Creek dikes, first built in the late 1600s. Their tops are at about 8.5 feet, which DNREC notes is below the 100-year flood elevation, and rising sea levels are widening the areas that flood at high tide.
The city’s own floodplain page says most of New Castle is either in the floodplain or close to it, and properties in the AE zone fall under the city’s floodplain ordinance, which affects substantial repairs and additions. One point in owners’ favor: the city takes part in the federal Community Rating System at Class 8, which brings a 10 percent discount on flood insurance. Check your parcel on FEMA’s Flood Map Service Center. We buy in flood zones and after water damage; see flood and storm damage.
Prices in and around New Castle
Zillow’s New Castle, DE index was $281,557 in its August 31, 2026 update, down 0.3 percent over the year, with homes going pending in about 10 days. The Census Bureau’s QuickFacts for the city give a close figure, a $285,100 median for owner-occupied homes over 2020–2024, and a $1,739 median gross rent. Zillow does not say whether its New Castle area matches the city limits exactly, so treat it as a rough guide.
A restored brick house on the Strand and a ranch that needs everything are priced in different worlds. If yours is well kept and nothing is forcing a quick sale, a listing will often bring more. If it needs major work, sits in a flood zone that worries buyers’ lenders, or has to be sold on a schedule, ask us for a number and compare.
Outside the city, with a New Castle address
If you have only the county tax bill, your house is in unincorporated New Castle County, and the city’s rules above do not apply. Instead, the county registers rentals (free, renewed by May 1 of each odd-numbered year), requires vacant properties to be registered within 90 days, and handles code complaints at 302-395-5555. Transfer tax there is 2.5 percent to the state and 1.5 percent to the county. The New Castle County page covers those rules in full, and the Bear page covers the suburbs to the southwest.
Wherever the house is, a foreclosure follows the same path: a Superior Court case in Wilmington, mediation for owner-occupants, and a sheriff sale on the second Tuesday of the month at the City/County Building. You can sell until the court confirms that sale. The Attorney General’s mediation hotline, (800) 220-5424, is free, and our foreclosure guide explains the timing.

New Castle sellers ask
Is my house in the City of New Castle or just the New Castle mailing area?
Check your tax bills: a house inside the city gets a bill from the City of New Castle as well as the county bill. If you only receive the New Castle County bill, the house is in an unincorporated area governed by the county.
Do you buy houses in New Castle, Delaware?
Yes, we buy inside the city, including the historic district, and throughout the surrounding New Castle mailing area. Houses can be sold as-is, with belongings left behind.
When are City of New Castle taxes due?
Bills are mailed in mid-July, a 2 percent discount applies if you pay by August 31, and a 6 percent penalty is added on October 1, plus 1 percent interest each month after October. City Finance is at (302) 322-9804.
Do city residents also pay New Castle County taxes?
Yes, city owners get the county bill for county and school taxes too. This year it is due December 31, 2026, after the General Assembly moved the schedule.
Can I sell a house in the historic district without making repairs?
Yes, you can sell it to us as it is. Exterior work in the district needs a Historic Review Certificate from the Historic Area Commission in addition to a building permit, so we take that on after we buy.
How do I stop water and electric service when I sell?
Both come from the Municipal Services Commission at 216 Chestnut Street, (302) 323-2330. You file its Disconnection of Service form for settlement day, and the buyer applies for a residential transfer of service.
Is the City of New Castle in a flood zone?
Much of it is: the city says most of New Castle is in or near the flood hazard area. Check your own parcel on FEMA’s flood maps, and note that the city’s Class 8 rating brings a 10 percent flood insurance discount.
Do I need a license to rent out a house in the city?
Yes, landlords with residential rental units inside the City of New Castle need a Rental Housing Business License. Outside the city, the county’s free rental registration applies instead.
What school district covers New Castle?
The Colonial School District, which runs George Read Middle School and William Penn High School on Basin Road. Its school tax is collected on the county bill.
How long does a sale to you take?
Our figure normally comes the day after we walk through, and settlement can follow in about a week once the title is clear. An estate, liens or a later move-out date simply push the date back.
