How this compares to its street

This parcel's assessed value rose 8.3% between the last two rolls. Across the 80 comparable parcels on Forest Ave, the median rose 2.0%.

That is 6.3 points above its own street. A finished renovation, an addition, new construction, or a correction to a previously low assessment all do this, and none of them is an error.

If none of those happened here, ask the assessor what changed. Grievance season in Westchester has the deadlines; miss one and you wait a year.

Screening comparison only, computed from published rolls. It does not account for what is physically on the lot. Confirm everything with the assessor before acting.

Nothing turned up in the records checked above. Records only show what was reported to an agency.

Compiled from published federal, state and municipal records on 2026-09-16. Each finding names its source and links to the agency that holds the underlying file. FEMA flood zones are regulatory map boundaries, not forecasts — flooding occurs outside them. A DEC spill record is a report filed at an address, not a determination about the building; a closed case means the agency closed its file. This section is not a risk score, an all-clear, or insurance, legal, appraisal, or real-estate advice. Confirm anything material with FEMA, DEC, your insurer, counsel, and the municipality before you act. See also Terms of Use.
