The Hunterdon County market
Hunterdon’s difficulty is thin sales volume against unusually individual property.
Much of the county turns over slowly. In a rural township there may be only a handful of relevant sales in a twelve-month window.
That forces the analysis to reach further back in time, or further out in distance. An honest report says plainly which it did.
The property itself resists matching. A converted stone barn in Delaware Township, a period colonial in Readington and a new build in Raritan Township are not variations on one house.
Three things do most of the work in an appraisal here.
Acreage. Land contributes at a declining rate past what a buyer would actually use. Ten acres is not ten times one.
Outbuildings. Barns, arenas and equipment buildings rarely return their cost. What they contribute is a question of market evidence, not of replacement cost.
Deed restrictions. A conservation or farmland preservation easement removes development rights permanently, and that removal has to be reflected in the land value rather than noted and passed over.
Lambertville and Clinton are their own markets again — small, walkable, historic stock where condition and period integrity carry more weight than gross living area.
Appealing a Hunterdon County assessment
Appeals are filed with the Hunterdon County Board of Taxation. The filing deadline is April 1, moving to May 1 in any municipality that implemented a revaluation or reassessment for the tax year.
The appraisal supporting the appeal needs an effective date of October 1 of the pre-tax year — not today's date — and the board applies the Chapter 123 Common Level Range, which can mean no reduction even where the property is worth less than its assessment. How the Chapter 123 test actually works .
Every Hunterdon County municipality has its own certified average ratio, and it decides the outcome before any appraisal is commissioned. The Chapter 123 calculator works out where a given assessment lands — including whether an appeal would raise it.
