A Private Pricing Opinion — what your apartment at 659 Baltic 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.
659 Baltic Street is a four-story, four-unit building of about 3,800 square feet, put up in 2008 on a 2,000-square-foot lot on the Fourth Avenue end of Baltic Street. It sat on a single tax lot as a four-unit building until a 2019 remodel, a condominium plan filed in 2022 and a 2024 subdivision into four condominium lots. How the apartments were occupied before the plan was not established in this review.
The four homes closed for a combined $5.31 million, about $132,000 above the $5.18 million offering total. Most of the small Brooklyn plans reviewed alongside this one, including 291 Sixth Avenue and 218 Classon Avenue, closed below their offering totals.
Architecture and residences
The Department of Buildings new-building job was filed in June 2007, fully permitted in August 2009 and signed off in August 2012. Two 2019 filings, both signed off, covered the conversion: one to remodel the four existing apartments, add storage bins in the cellar, strengthen the roof for a roof deck and install new condensers on the bulkhead; the other to create storage accessory to the "proposed condominiums" and convert the roof to an open deck. A subdivision completed in January 2024 split the lot into four residential condominium lots, 1501 through 1504.
Listing records describe floor-through two-bedroom homes. Residence 3 is listed at about 893 square feet with two bedrooms and one bath; a garden home is listed at about 1,600 square feet with two bedrooms and two baths, a figure that likely includes lower-level space. Shared features listed are the roof deck, private storage and a virtual doorman. Listing records show common charges of $745 a month and taxes of $12,948 a year on Residence 3.
Offering and pricing
Per the offering plan filed with the New York State Attorney General (plan CD220160), the plan was submitted July 27, 2022, accepted October 10, 2023 and declared effective November 27, 2024, with Cabbad Co., LLC as sponsor and four residential units, at a total offering price of $5,175,000. The database records one unit sold, a figure it has not updated since closings. The Attorney General's plan page returned no data on the day this page was written, so the amendments were not reviewed.
One date does not reconcile. ACRIS shows two deeds dated September 24 and 25, 2024 (the one checked names the sponsor as seller), two months before the effective date in the database. A plan is normally declared effective before closings; the database date may record when the effectiveness amendment was reviewed rather than when it took effect. The amendment itself would settle it.
Listing records showed Residence 3 at $1,300,000 and the garden home at $1,500,000 (August 2024).

What to know if you’re buying
Every purchase is a resale. The sponsor sold the last home in July 2026.
A 2008 building, remodeled. The structure is about 18 years old. Ask for the 2019 sign-offs, the roof-deck structural work and the age of the boiler and condensers.
Four owners. The condominium is small. Ask how the reserve fund is held and how roof and façade costs are shared.
Carrying costs. Listing records show $745 a month in common charges and about $1,080 a month in taxes on an 893-square-foot home. Confirm both before signing.
Closing costs. In a resale the buyer pays the state mansion tax of 1% at $1 million and above, plus title and recording costs. Use the calculators below.

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.
