A Private Pricing Opinion — what your apartment at 15 Lynch 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.
15 Lynch is a twelve-apartment condominium from the first wave of South Williamsburg new construction, filed in 2000 and finished in 2005. It is easy to misfile. The condominium's legal name covers 11 through 15 Lynch Street, but the building at 11 Lynch Street is a different, later condominium with its own billing lot. City records also disagree on the building's age by four years, and none of them gives the completion date.
Recorded deeds establish individual condominium transfers. The sponsor conveyed all 12 apartments between 2004 and 2006, and the recorded grantee names differ across the unit lots. Two of the twelve went to LLCs rather than individuals, one of them by a deed with no recorded consideration. Whether either is affiliated with the sponsor is not documented in the records reviewed. The grantee names and residential condominium classifications do not establish beneficial-owner independence, current occupancy or the absence of sponsor-affiliated holdings.
The 15-year 421-a has run out, so there is no remaining phase-out; future bills still change with assessments, rates and any other benefits.
Architecture and unit composition
A six-story building designed by Henry Radusky, RA, per the DOB filing, with two apartments on each floor. The unit designations run R and L, 1R and 1L through 6R and 6L.
The Department of Finance does not record unit areas for this condominium, so sizes have to come from the floor plans or the declaration. The assessments suggest the two lines differ: the L line on floors two through five is assessed about 20 percent above the R line. Assessment usually tracks size, but confirm square footage from the plans before comparing prices.
Bedroom counts, exposures and outdoor space are not documented in the records reviewed.
Building operations
The 421-a has expired. The Department of Finance exemption file shows a 15-year 421-a exemption (code 5113, "421A 15 YR NO CAP") on all 12 unit lots, from a 2001 base year with benefits starting in fiscal 2007. The exempt amount was still on the fiscal 2021 roll and is zero from fiscal 2022 onward. No 421-a appears on the fiscal 2027 roll.
At the fiscal 2027 taxable assessments and a Class 2 rate of roughly 12.5 percent, that works out to about $16,500 a year for both ground-floor apartments and the R line on floors two through five, and about $18,400 to $19,800 for the L line on floors two through five and both sixth-floor apartments. These are our estimates from the roll, not bills, and individual bills can differ where an owner holds a personal exemption. Confirm against the current tax bill.
Registration. The condominium files an HPD multiple-dwelling registration in its own name, most recently in July 2025, with a managing agent listed.
Operating detail. Staffing, the budget, reserves, any assessment and the capital record of a 20-year-old building are not documented in the records reviewed. On a building of this age, ask about roof, façade and mechanical replacement cycles.

Open-market resales are rare. ACRIS shows two arm's-length resales across 12 apartments since the original unit conveyances ended in 2006, in 2010 and April 2026. The other later deeds are transfers into trusts or between related parties. Most apartments have not changed hands on the open market since the sponsor sold them.
The building trades against South Williamsburg's mid-2000s condominium stock, priced in dollars per square foot. With so few trades, the building's own history gives little guidance, and pricing has to lean on the same-era condominiums nearby. Most of that cohort has also come off its 421-a, so the tax comparison against same-era buildings is close to even. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-02230-7504; each condominium apartment is its own tax lot). Apartment-level facts (line, condition, asking-price context) curated and cross-verified in The Roebling Research Library. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price; square footage from recorded condo declarations and offering plans.

What to know if you’re buying
Identify the lot, not the name. Your contract, title report and lender file should carry billing lot 7504 and the specific unit lot, 1401–1412. The condominium's name covers 11 Lynch Street, which is a separate condominium.
Get square footage from the plans. The city roll carries no unit areas here. Ask for the floor plan and the declaration's unit schedule before comparing prices per square foot.
No 421-a phase-out remains. Taxes still change with assessed value and tax rates, and common charges and building assessments can change too.
Get the governing documents from the managing agent. No offering plan was located. Leasing rules, pets, any resale contribution, the budget and the reserve balance all have to come from the managing agent and the declaration and by-laws.
Confirm the certificate of occupancy. It is not in the digitized record. Your attorney should pull it from the Department of Buildings.
What to know if you’re selling
Document the size. With no unit areas on the city roll, a measured floor plan settles the per-square-foot comparison before a buyer's broker raises it.
Correct the year built. Listing data that carries 2001 or 2003 describes the permit period. The building was signed off in November 2005.

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.
