This building does not have enough sales with a recorded floor area to chart its own price per square foot, which is usual for a co-op. The series above follows comparable homes across Williamsburg instead.
Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.

The City has not published the official FY2026/27 and FY2025/26 tax rates yet. We calculated the tax for those years using the prior year’s rate, so treat them as an estimate rather than a figure the City has adopted. Every rate without the Estimated marker is the published one.
Tax Assessment is the assessed value on the City’s roll, and it is the figure other listing sites publish. It is not what the bill is calculated on. New York phases assessment changes in gradually for some tax classes, so the City bills the Billable Value shown beside it, less any exemption the owner holds. It usually trails the assessment, and it can sit above it for a few years after an assessment falls.
Figures are the New York City Department of Finance assessment roll for tax lot 3024061308. Assessed and billable values are determined by the City for tax purposes and are not an appraisal or an estimate of market value. Tax classes and rates are set annually and can change.

Location Context
Williamsburg
Overview of Williamsburg
Williamsburg is the global poster child for urban cool. Located just across the East River from Manhattan, it is a cultural powerhouse known for its nightlife, art scene, and trendsetting style. For buyers seeking Williamsburg Brooklyn real estate, it offers the city's most dynamic and energetic living environment. Living in Williamsburg is fast-paced. The neighborhood is divided into the ultra-modern waterfront (Northside), the grittier Southside, and the quieter Italian/hipster mix to the east. As a premier Brooklyn NYC neighborhood, it rivals downtown Manhattan for influence and price.Real Estate & Housing Market
The market for homes for sale in Williamsburg is premium. The waterfront is lined with "glass castles" like The Edge and Domino Sugar Factory. Inland, you find converted lofts and renovated tenements. Demand is insatiable, driven by a young, affluent demographic that prioritizes amenities, views, and proximity to the L train.Lifestyle & Community
The lifestyle in Williamsburg is 24/7. Bedford Avenue is the main drag, packed with tourists and shoppers. The dining scene is world-class, featuring institutions like Peter Luger alongside new hotspots. The community is a mix of creative professionals, young families (the "stroller brigade" on the waterfront), and long-time residents, though gentrification has shifted the balance heavily toward the wealthy.Transportation & Accessibility
Williamsburg is served by the L, G, J, M, and Z trains. The L train at Bedford Ave is one stop from Manhattan, making the commute incredibly fast. The Williamsburg Bridge offers a bike path that sees thousands of cyclists commuting daily. The ferry terminals at North and South Williamsburg provide a relaxed alternative.Parks, Schools & Amenities
Domino Park and Marsha P. Johnson State Park (East River State Park) are the jewels of the waterfront. McCarren Park is the active center for sports and picnics. Amenities are unmatched: Whole Foods, Apple Store, Equinox, and hermès. Williamsburg has effectively become a self-sufficient city.Who This Neighborhood Is Best For
Williamsburg is best for socialites, trendsetters, and young families who want the excitement of Manhattan with the fresh air and views of Brooklyn.
