Algorithmic average-value citations ran around $1.62 million, while actual median SOLD prices reached $2.6 million (October 2025, +5.4% YoY) and $2,799,000 (March 2026) -- both figures disclosed rather than one cherry-picked.
New York State's graduated income tax applies, with NO separate village income tax
New York State's 2026 income tax runs 9 brackets, 4.0%-10.9%. Per this project's own New York manifest research, outside NYC and Yonkers, New York municipalities (including Sag Harbor) do not levy a separate local income tax.
A comparatively moderate county property-tax rate likely understates the true picture
Suffolk County's average effective property tax rate ran 1.7%-1.85% -- but a directly comparable East End citation put the Village of East Hampton's own assessment ratio at just 2%-4% of market value, suggesting Sag Harbor's own effective rate on true market value likely runs below the county average, though a Sag Harbor-specific figure was not separately found this pass.
The Peconic Bay CPF transfer tax is a real, distinctive East End-only closing cost
Buyers face a real, combined 2.5% Peconic Bay Region CPF transfer tax (allowances of $400,000 improved / $100,000 unimproved, with NO allowance at all above $2 million) -- a genuinely distinctive cost not found in most other New York markets.
