A Private Pricing Opinion — what your apartment at Park Slope Terrace 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 number that matters at 675 Sackett Street is its tax bill. The condominium has carried a 25-year 421-a exemption since the 2005/06 tax year. Under that program the city taxes a unit on its pre-construction base value and exempts the new building's value above that base. The exemption was 100% for 21 years. It dropped to 80% on the 2026/27 roll, and it falls another 20 points each July until it ends on June 30, 2030.
The step-up is steep because the exemption was so large. On one fourth-floor residence, the taxable assessed value on the 2026/27 roll is about four times what it was in 2025/26. At an unchanged assessment, it will roughly quadruple again by 2030/31. That is before any owner-level co-op/condo abatement, which is separate and applies only to qualifying primary residences. A buyer today is paying for an apartment whose tax line has only begun to rise. Any purchase analysis should use the 2030/31 tax number, not the one on the current bill.
The 25-year term also stands out. It is longer than the 10- and 15-year terms that were standard for condominiums of this period. The Department of Finance records confirm the 25-year term but do not say why it applied. Ask the managing agent whether any unit carries a regulatory or affordability restriction tied to the benefit. None appears in the ownership records we reviewed, and the unit lots are owned by a wide spread of individual buyers.
The rest is straightforward. Park Slope Terrace LLC built the building in 2003–04 under a permit filed in 2002. The declaration was recorded in February 2004, and the sponsor sold almost the whole building in a single season. ACRIS shows sponsor deeds for 37 of the 38 residences dated between April and December 2004. The sponsor holds no residences today. This was one of the first wave of mid-size condominiums along the Fourth Avenue edge of Park Slope. It predates the taller Fourth Avenue towers by several years and sits on a residential side street rather than on the avenue itself.
Architecture and unit composition
The building is four stories and 46 feet tall, per the new-building application, on a wide lot. It is clad in brick; DOB's 2013 façade-repair filing covered removal and replacement of brick masonry and flashings. It is built out beyond what today's zoning allows. The same building would not be permitted at this density under the R6B district now mapped on the lot, and that fixed supply supports value.
The residences are numbered 101–110, 201–211, 301–311 and 401–406. Management-sourced records describe the stock as mostly two-bedroom apartments with high ceilings, large windows and central air, plus several large duplexes. Some units have private outdoor space. The fourth floor carries six residences where the floors below carry ten or eleven, which points to larger top-floor units. Confirm the layout and any duplex or terrace rights for a specific unit from the floor plans filed with the declaration.
The garage is a single commercial unit, not deeded spaces. Lot 1201 is one condominium unit assessed as 19 parking spaces. The sponsor conveyed it for no recorded consideration to a parking LLC in November 2004. It was transferred again, also for no recorded consideration, to its current owner LLC in February 2020. Management-sourced records describe the underground parking as available by lease. At this building a buyer cannot buy a space with the apartment; parking is a rental from the garage-unit owner, on that owner's terms.
Building operations
The condominium is professionally managed and staffed by a full-time superintendent, per management-sourced records. DOB filings trace a steady capital record: a rebuilt fence wall in 2009, masonry and flashing replacement in 2013, cellar storage partitions in 2020, and a rooftop solar PV system filed in September 2023. At four stories the building sits below the six-story threshold of the city's façade-inspection program (FISP/Local Law 11), so there is no five-year façade cycle to review. Masonry upkeep is still a budget line, and the 2013 work is the most recent recorded façade job.
Ask the managing agent for the current budget, the reserve balance, any assessment in effect, the solar system's ownership and any lease or power-purchase terms, and the condominium's agreement, if any, with the garage-unit owner covering shared building systems.
Policy framework
Ownership form: Condominium. Resales are subject to the board's right of first refusal rather than share-transfer approval.
Pets: Cats and dogs permitted with approval, per management-sourced records.
Leasing: Subletting permitted. Short-term rentals and home-sharing platforms prohibited. A lease application with processing and move fees applies.
Pied-à-terre, secondary residence, co-purchasing, parents buying for children, corporate purchase: All permitted, per management-sourced records.
Financing: No condominium-level financing cap, per management-sourced records. Lender requirements govern.
Transfer fee: None documented. Confirm with the managing agent.
Real estate taxes: 421-a phasing out. Underwrite each year from 2026/27 through 2029/30, and the full unabated bill from 2030/31.
Recent sales
675 Sackett Street trades as early-2000s Park Slope condominium product, priced per square foot against the district's newer buildings. Mostly two-bedroom apartments on a residential block east of Fourth Avenue give it a clear buyer: someone choosing a condominium over a brownstone floor-through or a co-op, at a lower price per foot than new construction.
The phase-out is now the main pricing variable. Buyers and their lenders see the current tax bill, and an informed buyer sees the 2030/31 bill. The gap between them widens each July through 2030. Resales that disclose the full schedule up front hold their negotiation better than resales that let the buyer's attorney find it. Within the building, value turns on floor, exposure, outdoor space and whether a unit is one of the larger top-floor or duplex layouts. Parking does not convey, so it does not belong in the comparison. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

What to know if you’re buying
Model the tax bill to 2030/31. The exemption is 80% this tax year and ends June 30, 2030. Ask for the unit's DOF notice of property value, apply the phase-out schedule year by year, and use the full-tax monthly figure when you decide what the apartment is worth.
Ask why the term is 25 years. DOF confirms the 25-year term. Confirm with the managing agent that no unit carries a use or resale restriction tied to it.
Parking is leased, not bought. The 19-space garage is one unit owned by an LLC. Get the current rate and waitlist in writing if parking matters to you.
Read the recent capital record. Ask for the solar installation terms, the reserve balance and any assessment history since the 2013 masonry work.
What to know if you’re selling
Put the tax schedule in the listing file. A buyer's attorney will find the phase-out. A seller who presents it with the DOF figures sets the terms of that discussion.
Lead with size and outdoor space. The larger top-floor and duplex layouts, and any private outdoor space, are what separate a unit here from the building's standard two-bedroom stock.
Anchor to condominium comparables of the same era. Mid-2000s Park Slope and Fourth Avenue condominiums are the correct set, adjusted for each building's tax position. Comparing against a new building with a fresh abatement overstates the value of the monthly number.

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.
