130 Eighth Avenue (814 Carroll Street)

Eight stories of brick on an 11,800-square-foot corner lot, holding roughly 59,520 square feet of floor area. The design does its work with massing rather than detail: chamfered windows turn the corner instead of a decorative quoin, and the Carroll Street elevation steps back rather than holding a flat streetwall, which gives the apartments on that side light and gives the block a break in scale. Against the Romanesque and Renaissance Revival houses immediately around it the building reads as plainly of 1950, and it does not pretend otherwise.

The apartments follow the early postwar plan: entry foyers, defined living and dining space in the larger lines, bedrooms off a hall, and a mix weighted toward one- and two-bedrooms with a smaller set of larger corner layouts. Ceiling heights and detail are postwar rather than prewar, and buyers who want plaster mouldings and parquet borders are shopping the wrong building. What this stock delivers instead is efficient square footage, good closet counts, and windows placed for light rather than for period proportion. Within the building the price spread is set by floor, by whether an apartment holds a corner or the Carroll Street setback, and by renovation state.

Because the property sits inside the historic district, the window program is a Landmarks matter rather than a shareholder decision. Ask what the co-op's current window policy is, whether a building-wide replacement has been approved or discussed, and what the Commission has permitted here before.

130 Eighth Avenue Owners Corp. has run the building since the 1988 conversion. The documented operation — full-time door staff, a resident superintendent, elevators, a below-grade garage and an accessible lobby — is a staffed model, and it costs what staffed models cost. Seventy-two apartments carrying that payroll is a workable ratio, better than the district's forty-unit buildings and thinner than the ninety-plus buildings a block away, and it should be tested against the actual maintenance figure rather than assumed.

The garage deserves specific diligence. It is documented for the building and it is a genuine differentiator inside a historic district, but the Department of Finance's land-use record carries no garage area for the lot. Establish with management how many spaces exist, whether they are licensed to shareholders or operated commercially, what the charge is, how the waitlist works and how the income is treated in the budget.

For a 1950 masonry building now well past seventy, the capital agenda is predictable and should be diligenced by document rather than by description: FISP/Local Law 11 façade cycles, roof and parapet, elevator modernization, boiler and distribution, and windows. The corporation's recorded credit agreement with Apple Bank for Savings, executed in December 2018 at $2,000,000, is a useful anchor for the debt conversation, but the current position belongs in the financial statements. Ask for the last two FISP filings, the reserve balance, the assessment history, the underlying mortgage terms and maturity, and the board's five-year capital plan. The corporation's financial statements are maintained in The Roebling Research Library and reviewed with clients during diligence; no managing agent is asserted here and the agent of record should be confirmed with the board.

The cooperative's house rules, sublet policy, pet policy, flip tax and financing standards are not publicly documented in the materials available to us, and this page will not guess at them. Request all five in writing from management before an offer goes in, and read the purchase application, the current house rules and the most recent financial statements together rather than in isolation. What can be said with confidence is that the building operates in the standard cooperative form: board approval, a complete financial package and an interview.

One additional item belongs on the same list at this address: the garage. Whether a space conveys with the apartment, transfers by waitlist, or is unavailable altogether is a policy question with real monthly consequences in a neighborhood where off-street parking is close to unrepeatable.

Recent sales

Recent transfers at this building, from The Roebling Research Library. Prices are the transfer amounts recorded with the NYC Department of Finance; apartment-level detail is checked against the building’s own file in The Roebling Research Library before publishing.

Market read. Most recent trades (2026 to date) cleared a median $1,146/sf (floor-adjusted) across 1 sale. 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 1.4% from the last ask — a recurring negotiation gap worth pricing into any offer or listing strategy.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-01071-0014). 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 on co-ops is not officially recorded, figures shown are approximate.

Establish the garage before you value the apartment. Spaces, terms, waitlist and cost. Inside a historic district this is the least replaceable thing the building owns, and the DOF file does not confirm it — management does.

Read the Landmarks position on windows. The building is in the 1973 district. Replacement is a Commission matter, and what the co-op has already been permitted to do sets the cost and calendar of what you can do.

Price the period honestly. A 1950 plan inside a Victorian district is a specific product. It wins on light, layout and services and it does not win on detail. Comp it against buildings that make the same trade.

Ask for the debt and capital file. A recorded $2,000,000 credit agreement from 2018 is a starting point, not an answer. Get the current mortgage terms and maturity, the reserve balance, the FISP history and the five-year plan.

Get all five policies in writing. Pets, sublets, flip tax, financing standard and the garage rule. The reviewed records do not establish these current terms; reconcile management's answers with the governing documents.

Lead with staff and parking. A full-time attended lobby and a below-grade garage inside the Park Slope Historic District is a combination almost no competing listing can write. Confirm the specifics, then market them first.

Tell the site's story. The Feltman mansion by Montrose W. Morris stood on this corner until 1950. That is the kind of provenance a Park Slope buyer responds to, and it costs nothing to state accurately.

Have the building's answers ready. Because the policy framework is not public, the seller who can hand a buyer written confirmation of the pet, sublet, financing, flip-tax and garage rules removes the friction that stalls these deals.

Comp on two tracks. Anchor to the staffed elevator co-ops for carrying cost and to the Eighth Avenue prewars for location, and use matched 2025-forward sales rather than the building average.

• 220 Berkeley Place — the 1955 postwar co-op two blocks north; the nearest peer on plan logic and period
• 209 Lincoln Place — the ten-story 1928 co-op with its own parking lot; the other district address where off-street parking is part of the deal
• 225 Lincoln Place — six-story 1920s co-op with a documented flip tax and sublet framework

• 35 Prospect Park West — 1929 eighteen-story park-front co-op; the tall prewar alternative

• 420 12th Street (Ansonia Court) — the Ansonia Clock Factory conversion in the 2012 Extension; loft volume in Park Slope
• 300 8th Avenue — the 1920 co-op down the avenue, just outside the district line; the entry-price alternative on the same street
