How this compares to its street
This parcel's assessed value rose 21.8% between the last two rolls. Across the 10 comparable parcels on Nautilus Ln, the median rose 3.0%.
That is 18.8 points above its own street. A finished renovation, an addition, new construction or a correction to a previously low assessment can all cause this, and none of those is an error.
If none of those happened here, ask the assessor what changed. Grievance season in Westchester lists the deadlines. If you miss one, you wait a year.
This is a rough comparison from the published rolls. It does not account for what is physically on the lot. Confirm everything with the assessor before you act.
Transfer climate on this street
2 priced transfers in the last 24 months across 11 residential parcels. That is 1.9 times the Mamaroneck Village rate. Recent closes on a block are how a street gets into the elevated band.
If last year's town rate holds, about 0.9 of these 11 parcels would record a priced sale in the next 12 months. The number belongs to the street. It does not pin a date on a house.

Compiled from published federal, state and local records as of October 27, 2026. Each finding names its source and links to the agency that holds the file. A FEMA flood zone is a line on a regulatory map. It does not predict floods, and flooding also happens outside the zones. A spill record from the state environmental agency (DEC) is a report filed for an address. It does not say what is wrong with the building, and a closed case means only that the agency closed its file. This section is not a risk score, an all-clear, or insurance, legal, appraisal or real-estate advice. Before you act on anything here, confirm it with FEMA, DEC, your insurer, a lawyer and the town or village. See also the Terms of Use.
