A Private Pricing Opinion — what your apartment at 90 Herbert Street would likely sell for today, what it costs to sell, and what you’d walk away with — reviewed personally against condition, exposures, renovation quality, and the competition actually on the market.
90 Herbert Street is a four-story, seven-residence condominium on a 25-by-100-foot lot in East Williamsburg, near the Graham Avenue L stop, per listing records. The building has a red brick facade, and the sponsor materials describe herringbone floors, walnut cabinetry, quartz counters and travertine baths.
The plan went effective on December 22, 2025, which requires contracts on a threshold share of the homes. The Attorney General record shows three units sold, a figure that has not been updated since.
Price is the open question. The plan totals $8,060,500, or $1,151,500 per residence on average (our arithmetic). A townhouse-level residence, TH1, is reported sold at $1,995,000 in listing records, about 25 percent of the plan total by itself, while other homes in listing records ask $820,000 to $1,325,000. Listing records use nine unit labels (2A, 2B, 3A, 3B, 4A, 4B, PH, PHB and TH1) for a seven-unit plan, so some labels are alternate names or stale, and the asks should not be totaled. Read Schedule A against actual contracts before treating any average as a benchmark.
Architecture and residences
The Department of Buildings new-building filing describes four stories, 45 feet and seven dwelling units, with 7,360 square feet of construction floor area; the first permit issued in December 2023 and the filing signed off in February 2025. PLUTO shows a four-story building on an R6B lot, built in 2024, with a recorded condominium (number 6307). The architect of record is not named in the records reviewed.
Listing records describe central air, in-unit laundry, private storage and a remote doorman with video intercom and video security. The building is a walk-up. Pets, subletting and pied-a-terre use are listed as allowed and no flip tax is listed, per a listing record updated in October 2025; confirm each in the plan and by-laws.
Offering and pricing
Per the offering plan filed with the New York State Attorney General (plan CD240293), the plan was submitted October 10, 2024, accepted January 7, 2025 and declared effective December 22, 2025, with 90 Herbert St LLC as sponsor. The record lists seven residential units and no storage or commercial units. Our price file shows an initial price of $8,017,800 and a current price of $8,060,500, an increase of $42,700, or 0.5 percent. The Attorney General's detail page did not load in repeated attempts, so amendments were not reviewed.

What to know if you’re buying
The plan is effective. Contracts are binding under the plan's terms and closings can occur. Read every amendment.
Reconcile prices to the schedule. Ask for the unit-by-unit schedule and compare it to the asks above.
Closing costs. In sponsor sales the buyer customarily pays the New York State transfer tax (0.4%) and the New York City real property transfer tax (1% at $500,000 or less and 1.425% above), plus the state mansion tax of 1% at $1 million and above. Most residences here sit under or just above that line. Use the calculators below to run your price.
Carrying costs and abatement. The plan's budget projects common charges and real estate taxes. No tax abatement was confirmed in this review.
Sponsor control. The sponsor controls the board until enough units close to turn it over. The by-laws set the threshold.

How to read the facts on this page. Items attributed to an offering plan describe the building as it was offered at that filing — unit mix, square footage, the amenity program as planned. They are not a statement about how the building operates today. Tax and compliance figures are sourced separately to current City records and carry their own dates. House rules, staffing and fee policy can change by board resolution without any public filing: treat every policy line here as a starting point for diligence and confirm it with the managing agent. Where this page compares one building or neighborhood to another, that is our analysis of the recorded record — it names the measure, the period and the sample it rests on, and it is an observation about medians rather than a prediction about any particular apartment.
