DOF values are used for property taxation. Condo and co-op tax valuations can differ substantially from sale prices. This is a tax-purpose estimate; comparable sales remain a separate valuation source. Roll exemptions can include STAR under DOF’s published layout.

These values cover the whole tax lot and do not value individual co-op shares.

How we calculate your annual taxes:
Billable assessed value: $436,936.00
times the current tax rate: x 12.4390%
Annual property tax: $54,350.48

HOA, common charges and maintenance require documented building or unit evidence. Sales and DOB records do not establish these amounts. A zero property-tax bill does not establish zero PILOT or other ownership charges. Bills may change with tax rates or benefits; monthly figures are annual equivalents.
