Annual property tax: $148,421.92

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.

Public building financial filings

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.
