The 50 most expensive homes in Mamaroneck
These are the 50 highest full market values on the Mamaroneck 2026 assessment roll. Full market value is the assessor's estimate of what a property would sell for — it is not a listing price, and it is not what the home last traded for. Across all 3,285 residential parcels in Mamaroneck the median full market value is $1,448,000, so everything on this page sits far above the typical local home.
Two things worth knowing before reading the table. First, a high assessment is not the same as a high tax bill — exemptions, STAR, and the split between county, school, and village levies all move the final number, which is why the estimated tax column does not rank in the same order as value. Second, large parcels and estate properties often carry values that reflect land as much as the house standing on it.
