Sixty-six homes sold in Tewksbury Township over the twelve months through July 2026, at a median of $950,000 and an average of 43 days on market. That 43-day figure is the whole story of this page. Tewksbury is one of the slowest-moving markets in the entire dataset, and the town-wide 101% sale-to-list ratio hides how differently the price bands behave: the $1,400,000 estate tier took an average of 64 days and settled at 99% of list, while houses around $690,000 needed 42 days to reach 102%. There is no tier in Tewksbury that behaves like the twenty-day bidding markets twenty minutes east. Buyers here get something rare in this part of New Jersey. Actual time to think. Sellers here get punished for an optimistic first price in a way that sellers in Union County do not.

Sorted by bedroom count, which in Tewksbury tracks price closely. Read the days-on-market column first. It is the number that separates this township from its neighbours.
| Bedrooms | Sales | Median sale | Avg days | Sale-to-list |
|---|---|---|---|---|
| 2 | 3 | $630,000 | 26 | 111% |
| 3 | 17 | $690,000 | 42 | 102% |
| 4 | 32 | $986,000 | 37 | 101% |
| 5+ | 14 | $1,400,000 | 64 | 99% |
| Town total | 66 | $950,000 | 43 | 101% |
Houses at $986,000 are the centre of gravity here. Thirty-two sales, close to half of everything that traded, closing at 101% of list after an average of 37 days. That is the fastest meaningful segment in the township and it still took better than five weeks. A well-priced house in this band gets its buyer, but it does not get a queue.
Below that, the $690,000 band produced seventeen sales at 102% of list over 42 days. Slightly stronger against asking price than the mid-market, noticeably slower to get there. That combination usually means a smaller pool of buyers who take their time, look at everything available, and then pay close to the number when they finally commit.
The $1,400,000 tier is where Tewksbury diverges hardest from the towns around it. Fourteen sales, 99% of list, and an average of 64 days. More than two months. Estate buyers in Hunterdon County are not competing with each other. They are choosing among several properties at once, and the seller who wants a fast answer has to be the best-priced house on that short list, not the most expensive one.
The 2-bedroom row reads 111%, and it should be read as a curiosity rather than a signal. Three sales cannot describe a market segment; it is in the table for completeness and no conclusion on this page rests on it.
Your negotiating position depends entirely on which band you are shopping. Above $1,400,000 you have real leverage: 99% of list over 64 days means sellers at that level are waiting, and a considered offer below asking is a normal conversation rather than an insult. Between roughly $690,000 and $986,000 you have less room. Those bands closed at 102% and 101%, but you still have time, and 37 to 42 days on market means you are almost never forced to decide the same weekend you tour. Use it. This is one of the few markets in Ryan’s coverage area where a proper inspection and a genuine renovation estimate can happen before you are committed.
Price it right on day one or accept that you are going to sit. Tewksbury does not correct an overpriced listing with a bidding war three weeks later, because there is no bidding war in any tier here. The town-wide average of 43 days is already long, and it gets longer the higher you go. 64 days above $1,400,000. Every week of drift past that average erodes your leverage, because buyers in this market watch listing histories and treat a stale property as a discount waiting to be claimed. The correct strategy is an aggressive, defensible first price supported by real comparables, not a high number you intend to cut.
Two very different things happen to a dated house in Tewksbury, and lot size decides which. On a smaller lot, a home needing significant work gets no premium. It sits, and it sells at or below asking. That is part of what the $690,000 band is showing. 42 days to reach 102%, slower than the mid-market above it, because the buyer is an owner-occupier doing arithmetic on a kitchen and three bathrooms.
On a half acre or more, the same house is a completely different asset. It becomes a builder target, and the buyer is paying for land rather than for the house. In a township built on large parcels and preserved open space, that description fits a great many Tewksbury properties. Owners in this position are frequently priced off tired-house comparables and never find out what the land was worth.
Ryan Horvath is a Prominent Properties Sotheby’s International Realty agent and a former licensed New Jersey general contractor. Having a vendor network that will put a real number on the work, and whether a lot carries builder value rather than house value. Is the difference between those two outcomes. Buyers should understand the same rule in reverse: shopping sub-$1M on a large Tewksbury lot means competing with builders, not just with other families.
Tewksbury recorded 66 residential sales over the twelve-month period. That is a small enough number that individual transactions genuinely move these figures. The 14-sale estate tier and the 3-sale 2-bedroom row especially. A single unusual closing above $1,400,000 shifts the township median and the days-on-market average in a way it never would in a town selling two hundred houses a year. Treat the numbers on this page as an accurate description of what happened, not as a formula. Pricing in Tewksbury is done house by house, lot by lot, and village by village.
Against its Somerset County neighbours, Tewksbury is priced in the middle and paced at the back. Chester Township, immediately north in Morris County, posted a $925,000 median at 102% of list over 32 days. A nearly identical price point moving eleven days faster. Bernardsville, to the east, reached a $1,050,000 median at 100% over 35 days. Mendham Township is the more expensive comparable at a $1,350,000 median and 100% of list, and notably it shares Tewksbury’s slow rhythm at 54 days.
For buyers who want the same rural character at a materially lower entry point, Bedminster Township is the obvious alternative: a $495,000 median at 102% of list over 24 days, driven by a large condominium and townhouse inventory that Tewksbury simply does not have. The trade is real. Bedminster gets you into Somerset Hills schools and I-78 access for half the money, but not onto acreage. Tewksbury’s premium is land, and its cost is patience.
Tewksbury has no railroad station of its own. Commuters typically drive east to Far Hills, on NJ Transit’s Gladstone Branch, or south to a Raritan Valley Line station, and both involve a connection rather than a single seat to Penn Station. This is a driving township first: Interstate 78 runs along the southern end near Oldwick, and Route 22 and Route 206 carry most local traffic. Buyers who commute daily into Manhattan should plan on a genuinely long trip and budget for station parking. Buyers who go in two or three days a week find it entirely manageable, and that is the pattern most Tewksbury households have settled into.
Tewksbury Township School District serves students from kindergarten through eighth grade, with Tewksbury Elementary School for the younger grades and Old Turnpike School for the middle grades. For high school, Tewksbury students attend Voorhees High School, part of the North Hunterdon-Voorhees Regional High School District, which serves several surrounding Hunterdon County municipalities. Families relocating from a single-district town should note that structure: the K-8 district and the high school are separately governed.
Tewksbury Township is a rural Hunterdon County municipality of rolling hills, working horse farms and a great deal of permanently preserved farmland. It contains the villages of Oldwick, Pottersville, Mountainville and Fairmount. Those are the names buyers actually search, and they are hamlets within the township rather than separate towns. Oldwick is the recognisable centre, with a general store, a handful of restaurants and eighteenth-century buildings along Main Street.
Housing stock runs from restored colonial-era farmhouses through mid-century ranches to custom homes built on multi-acre parcels in the last thirty years. There is no downtown in the Summit or Westfield sense and no commercial corridor of any size; residents drive to Clinton, Chester or Bedminster for everyday shopping. What Tewksbury offers instead is space, quiet and land, and the market data on this page is a direct consequence of that. Fewer houses, fewer buyers for each one, and more time on both sides of every transaction.
The median sale price in Tewksbury Township was $950,000 across 66 residential sales recorded in the Garden State MLS between August 2025 and July 2026. Homes averaged 43 days on market and sold at 101% of list price.
It depends on your price band, and the split is sharp. Above $1,400,000 it is a buyer’s market: 99% of list over an average of 64 days gives buyers real negotiating room. Between roughly $690,000 and $986,000 it is balanced, with sales at 101% to 102% of list. Sellers get their price, but only after 37 to 42 days. No segment of Tewksbury is a fast seller’s market by the standards of Union or eastern Somerset County.
The average sale price was $1,059,153 against a median of $950,000. A gap of more than $100,000. That happens because a small number of large estate sales pull the average upward while the median stays anchored to the typical transaction. With only 66 sales in the year, a handful of properties well above $1,400,000 is enough to move the average noticeably. The median is the more honest description of what a normal Tewksbury house sells for.
Forty-three days on average, which is among the longest in the region. The mid-market around $986,000 moved fastest at 37 days; the $1,400,000-and-up tier averaged 64 days. Sellers should plan their timeline around two months rather than two weeks, and should expect that pricing accuracy at launch matters far more here than in faster neighbouring markets.
Sales above $1,000,000 in Tewksbury trigger New Jersey’s Graduated Percent Fee, formerly the “mansion tax.” Since July 10, 2025 it is paid by the seller rather than the buyer, starting at 1% of the entire sale price and rising with price. Because the rate steps up at fixed thresholds, a sale crossing one by a small margin can cost more than it gains. See the New Jersey mansion tax seller’s guide for the brackets and where the thresholds fall.
