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: $4,716,090.00
minus exemptions: – $13,643.00
times the current tax rate: x 12.4390%
minus abatements and/or STAR: – $71,518.44
Annual property tax: $513,418.96
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.
NY Attorney General offering plans and amendments can document budgets, financial statements, reserves and sponsor obligations. These records cover the development, including properties without active listings.
No exact offering-plan match has been collected here yet. Eligible condo and co-op properties are queued when viewed. Missing filings do not establish zero fees, assessments or debt.
Tax-benefit schedules, statement balances, penalties and declared capital work cover the identified tax lot. Condo billing-lot evidence is shown separately from apartment evidence.
