A Private Pricing Opinion — what your apartment at Lofts1 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.
Lofts1 is one of the early Southside conversions: a 1911 four-story manufacturing building just west of Havemeyer Street, bought by the sponsor in March 2005 and filed for residential conversion the same year. The plan is dated November 2005, construction ran through 2007, and the sponsor closed 22 of the 23 apartments between October 2007 and September 2008, per ACRIS. The last sponsor unit sold in December 2011. The sponsor holds nothing today.
The building's shape comes from the conversion. The original floors were divided into two bands of compact lofts on the second and third floors, larger units on the ground floor with cellar space below, and a top floor that gained a mezzanine level built on the roof. Above that, the roof was split into seven separately deeded terrace units. How a unit is priced here depends mostly on which of those four types it is.
The building also has a recent capital history that a buyer needs to read. Between 2017 and 2024 the condominium replaced every window and completed major façade and roof repairs, financed by owner assessments and a bank loan that runs to 2030. The work is finished. Part of the payments are still running.
Architecture and unit composition
The unit mix, per the revised Schedule A and floor plans in the First Amendment (June 2006), and Department of Finance unit areas:
- Ground floor, 1B–1F: five units of roughly 1,070 to 1,430 square feet including a cellar level, with two baths each. These are the building's largest units apart from the top floor.
- Second and third floors, A–F: twelve compact lofts of roughly 560 to 665 square feet. The A through D lines are drawn as a single living, dining and sleeping room; the E line has a separate bedroom.
- Fourth floor, 4A–4F: six units of roughly 1,150 to 1,450 square feet, each with a mezzanine and accessory storage in the rooftop addition.
The roof-terrace units are the feature to understand. Each of RT1 through RT7 is a separate condominium unit with its own tax lot, deed and share of common charges. Six are owned by apartment owners, mostly on the fourth floor, and one is held by the condominium itself, per the Department of Finance. A listing that includes a terrace is selling two or three conveyances, and title work should confirm each one.
The building is a walk-up per its Department of Finance class. The house rules require carpet or similar covering on 75 percent of exposed floor outside kitchens and baths, a standard noise rule in converted loft buildings, and they bar new window or through-wall air conditioners without the board's consent.
Building operations
Lofts1 is small and run lean. The 2024 audited statements show about $183,000 in common charges against about $145,000 in operating expenses, the largest items being insurance, repairs and a contracted janitorial service.
The capital project and the loan. In 2017 the board began planning a project to stop water coming through the exterior: full window replacement, façade repairs and roof work. It was funded by an initial capital assessment, then a $1.5 million bank loan taken in May 2019 at a fixed 2.69 percent, then continuing capital assessments to pay the loan. Windows were finished in May 2022. The façade and roof work began in August 2022, ran long because of access problems, and was completed in September 2024. Rising costs required an additional special assessment, approved in February 2024 and paid off by December 2024. About $2.3 million of work has been capitalized.
What remains is the loan. Its balance was about $865,000 at the end of 2024, and it amortizes on a fixed schedule to May 2030, with a small final payment at maturity. In 2024 the condominium collected more than twice as much in capital assessments as in common charges. A buyer's true monthly cost here is common charges plus the capital assessment plus taxes, and the assessment should run until the loan is repaid. Reserves were about $192,000 at year-end 2024. The condominium has not commissioned a reserve study, which is a professional estimate of future replacement costs.
The tax position
The roll shows no tax benefit to lose. Department of Finance records show no 421-a or J-51 exemption on any residence or terrace unit in any year from 2010/11 through the 2026/27 roll; the only exemptions recorded are individual owners' personal exemptions. Abatements are applied on the bill, not the roll, so check each apartment's current tax bill before comparing Lofts1 against Williamsburg condominiums of the same age whose 421-a benefits have been stepping down.

Recent sales
Lofts1 trades as Southside loft-conversion product, priced in dollars per square foot, and the spread inside the building is wide because the unit types are so different. The compact second- and third-floor lofts trade against Williamsburg's studio and one-bedroom resale market. The fourth-floor mezzanine units, especially those sold with a roof terrace, trade against larger lofts and penthouse-style units nearby. The ground-floor units price on their cellar space, which buyers weigh very differently from above-grade space. For all of them, the running capital assessment belongs in the comparison. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

Market read. Most recent trades (2026 to date) cleared a median $1,058/sf (floor-adjusted) across 3 sales. Floor-adjusted means each sale is restated to a constant mix of floors, so the figure can differ from the plain median of the sales listed above. Median listing discount 1.7% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

What to know if you’re buying
Get the assessment schedule in writing. Ask the managing agent for the current monthly capital assessment on the unit and how long it is budgeted to run. The loan matures in May 2030.
Confirm the terrace. If the listing includes a roof terrace, it is a separate unit with its own deed, taxes and common charges. Make sure the contract covers it.
Read the 2017 and 2019 declaration amendments. Both were recorded against every unit. Have your attorney confirm what they changed before you sign.
Check the pet rule. The house rules let the board restrict or prohibit animals, and a later rule binds existing owners.
Allow for the right of first refusal. The board reviews each sale and notifies the parties whether it waives. Build that into the contract timeline.
What to know if you’re selling
Lead with the completed exterior work. New windows, façade and roof finished in 2024 answer a buyer's first question about a century-old building.
Disclose the assessment up front. Buyers will find it in the financial statements. Presenting the monthly figure and the 2030 end date yourself keeps it from turning into a late price discussion.
Prepare the multi-deed file early. A fourth-floor unit sold with one or two terrace units is several conveyances; have every deed and tax bill ready.

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.
