"PILOTs have a positive value for Dunellen," Mayor Jason Cilento wrote in a 2021 message to residents, explaining why the borough was leaning so heavily on payment-in-lieu-of-taxes agreements to rebuild its downtown. He was making a case for a financing tool. He wasn't writing a buyer's guide. But that one sentence explains more about what's happening to Dunellen home prices in 2026 than any single statistic on a listing page.
Here's the problem a buyer runs into. Two homes in Dunellen can sit at nearly the same price, in the same zip code, a few blocks apart, and be answering to completely different tax rules. One was assessed the ordinary way, by the Middlesex County Board of Taxation, based on what a willing buyer would pay for it today. The other was priced under a negotiated PILOT agreement that has nothing to do with the county's assessment formula and won't for years. If you're comparing Dunellen to a neighboring town on price alone, you're comparing two different products that happen to share a mailing address.
Same Zip Code, Two Different Tax Bills
Dunellen's housing stock is mostly old. The bulk of it dates to 1940 or earlier, small ranches and colonials on modest lots, taxed the conventional way: the county assessor sets a value, the borough, school district, and county each take their share, and the bill moves with reassessments over time.
Sitting on top of that older stock is a wave of new construction tied to a specific 19-acre site: the former Art Color factory, redeveloped into what's now known as The Nell at Dunellen Station and The Crossing at Dunellen. K. Hovnanian built the for-sale townhomes there; Prism built the rental apartments and retail space. One recently sold unit in The Crossing, a 1,618 square foot townhome at 240 Park Lane built in 2022, closed. A home built in 1927 is down the street.
The Math Behind the PILOT
The borough's own accounting, laid out publicly in 2021, shows why officials pushed so hard for this structure. Before redevelopment, the parcel that became Dunellen Station was generating roughly $250,000 a year in property taxes as an underused commercial site. Once built out with market-rate townhomes and apartments, the borough projected the completed site's value would approach $100 million, with negotiated PILOT and land tax payments bringing in about $700,000 in the first year alone, a number built to keep climbing for three decades.
The reason a PILOT is attractive to a municipality, and not just a developer perk, comes down to who keeps the money. Under a conventional property tax bill, Dunellen keeps only about 26 percent of every dollar collected, with the rest split among the school district, the county, the library, and open space funds. Under a PILOT, the borough keeps 95 percent. That split is why Dunellen has leaned on this tool for downtown redevelopment rather than waiting for organic reassessment.
None of this makes a PILOT-taxed unit a bad purchase. It makes it a different purchase, one where the effective annual carrying cost is fixed by contract rather than by the open market, at least for the length of the agreement.
| Legacy Dunellen housing stock | New construction under an active PILOT | |
|---|---|---|
| Typical vintage | Mostly built 1940 or earlier | Built since 2022, concentrated in The Crossing at Dunellen and The Nell at Dunellen Station |
| Tax basis | County-assessed, adjusts with reassessment | Fixed by a negotiated PILOT schedule, not tied to county assessment |
| Who sets the number | Middlesex County Board of Taxation | Terms of the individual redevelopment agreement |
| Payment due dates | Quarterly, same borough schedule | The Dunellen Tax Collector lists quarterly due dates matching regular taxes (Feb 1, May 1, Aug 1, Nov 1) |
| What a buyer should ask | Recent assessment history | Years remaining on the PILOT term |
Why the Median Price Swung From $557K to $612K
This same blending shows up in the price data buyers actually see on portals, and it's worth walking through because the swing looks dramatic if you don't know what's driving it.
Multiple listing service figures for the three months ending May 2026 put Dunellen's median sale price at $557,000, up a modest 2.7 percent from the same window a year earlier, with homes taking an average of 77 days to sell, up from 45 days the year before. Read on its own, that looks like a market cooling off. Twenty-six homes sold in Dunellen in May 2026, compared with just 14 in May 2025, nearly double the volume.
Now look at the most recent single-month snapshot available, reflecting closings through June 2026 and current as of August 2026. Median sale price: $612,167, up 15.5 percent year over year. Average days on market: down to 37, a full ten days faster than the month before.
Those two pictures don't describe two different markets. They describe the same small market with uneven timing. Dunellen typically sells somewhere between a dozen and two dozen homes a month. When a batch of new-construction PILOT units in The Crossing at Dunellen closes in the same few weeks, it can pull the median and the days-on-market figure in whichever direction that batch happens to land, simply because the sample is so thin. A town with a few hundred sales a month can absorb a dozen new closings without much notice. A town with fourteen to twenty-six can't. That's the real lesson in the swing from $557K to $612K: it's less a story about demand shifting and more a story about how few transactions it takes to move a median in a small market carrying an active redevelopment pipeline.
The Redevelopment Isn't Finished
If this were a one-time blip, you could shrug it off. It isn't. In May 2026, the borough finalized an Amended and Restated Downtown Redevelopment Plan that still designates several sub-areas for further redevelopment, including Train Station North on Block 69, Train Station South on Block 70, and the stretch of South Washington Avenue between the rail line and Columbia Street. In June 2026, the borough and NJ Transit announced continued progress on the Dunellen Train Station Modernization Project, with NJ Transit pursuing federal grants for accessibility improvements including elevators and ramps at the station.
Dunellen has been building toward this since it was designated New Jersey's 26th Transit Village in 2012, and the borough's own redevelopment page points to the pattern directly: successful projects on formerly vacant sites, it notes, increase property values borough-wide and help stabilize the tax burden over time, since roughly 90 percent of Dunellen's current tax base sits on residential property. That's a reasonable long-term goal for the town. For a buyer trying to read this year's numbers, it also means more PILOT-eligible new construction is still coming, and the blended, occasionally noisy price data this creates isn't likely to settle down soon.
What to Ask Before You Compare Two Listings
If you're weighing a Dunellen listing against a similarly priced home in a neighboring town without an active PILOT, a few questions matter more than the sticker price:
- Is this specific unit inside the PILOT redevelopment area, or in the borough's older housing stock outside it?
- How many years remain on the PILOT term, and does the payment increase on a set schedule?
- Does the online listing's tax estimate reflect the PILOT payment, or a generic county estimate that doesn't apply to this unit?
- What happens to the payment once the PILOT term ends, and is that date documented anywhere you can verify?
Dunellen's Tax Collector posts PILOT properties online under a separate section from regular tax payments, and that's the place to start if a listing agent can't answer these questions directly.
A Few Practical Questions
Will the tax bill jump once a PILOT ends? For the borough's separate five-year improvement abatement program, adopted under Ordinance 2022-16, the answer is yes: after the five-year term, the borough collects the full assessed value that would otherwise have applied all along. The longer, 30-year PILOT agreements tied to large redevelopment projects like Dunellen Station are structured differently, with a payment schedule set for the life of the agreement rather than reverting partway through.
How do I check if a specific listing is under an active PILOT? Ask the listing agent, or contact the Dunellen Tax Collector's office directly. PILOT properties are listed separately from conventional tax records, and the borough has said plainly that PILOT properties are not tax exempt, meaning there's an active, verifiable payment obligation attached to the parcel.
Dunellen's median price will keep moving in ways that look confusing if you're only checking a portal once. The town is mid-build, and a mid-build market doesn't behave like a settled one.
