Binghamton's assessment roll runs from Downtown and the West Side to the First Ward and the riverfront — a Southern Tier city at the confluence of the Susquehanna and Chenango. Many owners carry assessments that don't reflect actual market conditions or property condition.
An assessment is an opinion, not a final number. Duffy & Catlin PLLC represents commercial, industrial, and residential owners across Binghamton and Broome County in challenging assessments that don't hold up — at no upfront cost.
When City of Binghamton builds its assessment roll, properties are valued in bulk using broad market models. Those models lean on neighborhood-wide trends — not your building's condition, your block, your actual rent roll, or the most relevant comparable sales.
Binghamton's economy is anchored by Binghamton University, healthcare, and a manufacturing heritage that traces back to IBM's founding here. Flood exposure along the rivers, aging commercial stock, and shifting demand all complicate valuation — and mass models rarely capture them. New York law lets you challenge an excessive assessment, but only within the window set by the city's charter.
Commercial and industrial properties are especially vulnerable to over-assessment in a mass revaluation. The income, cost, and sales-comparison approaches each require proper application — and a mass model doesn't always get Binghamton right.
Downtown office, Court Street retail, and mixed-use are frequently assessed without proper regard for real vacancy, lease terms, or market income. We apply the correct methodology to challenge inflated values.
Manufacturing, warehouses, flex space, and riverfront industrial carry functional obsolescence, flood exposure, and thin comparable sales that mass appraisals routinely miss.
Homes, doubles, and student rentals across the West Side, First Ward, and South Side all benefit from review. Even modest increases compound into real tax liability over an assessment cycle.
New York calculates an equalization rate for every municipality — the ratio of assessed value to full market value. When Binghamton and Broome County market prices rise faster than assessments are updated, that rate falls, and the State treats your property as worth more for purposes of county tax apportionment.
The result is a larger share of the Broome County levy landing on your bill — with no change to the assessment roll and no formal notice. If your assessment was already excessive, the compounding effect is even greater. A timely challenge corrects both problems at once.
