Largest assessment decreases in Ardsley, 2025 to 2026
The 50 largest downward moves in assessed value between the 2025 and 2026 Ardsley rolls. 18 parcels fell in total.
Decreases are less common than increases and tend to be deliberate: a successful grievance or small-claims assessment review, a demolition, a fire or other loss of improvements, a subdivision that moved value onto a new parcel, or a correction. Where a drop reflects a won grievance, it is a useful signal — it means the assessor accepted that comparable properties supported a lower valuation.
Same exclusion as the increases page: parcels under $200,000 on the prior roll are left out.
