A Private Pricing Opinion — what your apartment at The Merchant House 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.
The Merchant House is a 21-unit loft conversion of two former manufacturing buildings on Dean Street. It predates the Pacific Park development across the street by a decade. The sponsor filed the offering plan in 2004, declared it effective that August, and closed all 21 units with separate buyers between April and December 2005. No sponsor inventory remains, and none has been held back as rentals. Nearly every unit has since resold at least once.
Two things set it apart from the new-construction condominiums around it. The first is size. The offering plan lists units of roughly 1,250 to 2,340 square feet, large for their bedroom counts, with the biggest layouts on the ground floor. The second is scale. Twenty-one owners, one elevator, a garden and a small board run a building with none of the amenity load that drives common charges in a tower.
Architecture and unit composition
618 Dean is the four-story main building. Its seventeen units follow a simple grid: five on the ground floor (1A–1E) and four on each floor above (A–D). The offering plan lists the ground-floor units as one-bedroom layouts and the upper floors mostly as two-bedroom, two-bath units. 626 Dean, the lower second building, holds four units designated 2-1A through 2-2B. The plan lists them as one-bedroom, two-bath layouts. Listing records describe high ceilings, oversized industrial windows, oak floors and central heating and cooling. Private roof areas attach to some upper units, and alterations there must follow an engineer's roof feasibility study and the roof membrane warranty, per the house rules.
Building operations
Tax benefits: the J-51 has run out. The conversion qualified for J-51, and the effect was large. The sponsor's first-year budget showed building taxes of about $29,000 with the benefit against $172,000 without it. Department of Finance records show a 14-year J-51 exemption on every unit, phasing down through the early 2020s. Its value falls to zero on the 2024 roll. The companion J-51 abatement's certified-cost pool had been fully applied by 2021. Owners now pay unabated taxes. Anyone relying on a carrying-cost figure from before about 2022 is looking at a subsidized number.
Capital work. The condominium ran an exterior repair program under DOB jobs filed in 2017. It covered brick replacement, windowsill and lintel replacement, stone band and steel repair, and parapet replacement at 626 Dean. A 2016 special assessment of roughly $284,000 appears in the 2015–16 financial statements, and those statements show about $347,000 in reserve accounts at the end of 2016. Those statements were compiled on a cash basis rather than audited, and they note that the condominium had no reserve study. Ask for current statements and the status of the most recent Local Law 11 façade cycle.

- Leasing: Owners must give the board 30 days' notice and provide the lease and tenant contact details. No rentals shorter than 30 days. A fee of $100 per month applies to any rented unit

What to know if you’re buying
Underwrite full taxes. Use the current tax bill, not a listing's historic figure or the offering plan's schedule.
Know which building you are in. The two structures share one condominium and one budget, but the units at 626 Dean differ in layout and height from those at 618.
Confirm legal use and the façade cycle. The lot is zoned M1-1. Have counsel confirm the certificate of occupancy covers the unit, and ask whether any façade work or assessment is pending.

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.
