75 Prospect Park West

The building covers roughly two-thirds of its corner lot, with frontage on both streets. The house rules keep both street façades clear of dryer vents, antennas, cables and awnings; those go on the courtyard or rear elevations.

The sponsor's unsold-share schedules in the amendments allocate between about 215 and 305 shares per apartment, and 5,839 shares across 24 apartments averages about 243. That suggests a fairly narrow range of apartment sizes, though shares follow the plan's allocation basis rather than measured area. DOB filings since 2008 are single-apartment renovations, with no combinations; the count has stayed at 24.

Avenue-side apartments face the park, 3rd Street apartments face north over the district's rowhouses, and corner apartments have both. Upper floors on the park side are the most valuable apartments in the building.

Treasury apartments. The five apartments taken back from the sponsor in 1993 were occupied by rental tenants, and the corporation collected their rents. Two were still held at the end of 2013, per the audited statements. ACRIS shows the corporation selling apartments in 2009, 2016 and 2017, which is consistent with the last treasury units having been sold. Confirm with the managing agent that the corporation owns no apartments today.

Underlying mortgage. The audited statements show a $600,000, 25-year self-amortizing first mortgage at 7.84% closed in November 1997, and a $200,000 credit line that was paid off in 2009. ACRIS shows a new $670,000 mortgage consolidated into a $1.0 million agreement in October 2014, and a satisfaction recorded in May 2022. ACRIS shows no mortgage recorded against the lot since then. If that is correct, the corporation has no underlying debt — unusual, and a real advantage for maintenance. Confirm it with the managing agent, along with whether any line of credit is in place.

Capital work. A major façade renovation was under way in 2013, with about $311,000 capitalized by year-end per the audited statements. DOB records also show a dual-fuel burner adding natural gas to No. 2 oil (2012), retaining-wall repairs (2015), a boiler replacement (2022) and new entrance doors (2025). Get the current Local Law 11 status from the managing agent.

Taxes. The Department of Finance's historical J-51 file shows two abatements beginning in 1989, on about $37,700 and $27,200 of certified work at the 90% allowance. They were fully used by the 1999 and 2000 tax years. The current exemption roll shows nothing for the lot, not even shareholder exemptions. In 2013 the board voted to assess back an amount roughly equal to the cooperative tax abatement passed through to shareholders. Ask whether that practice continues.

• Flip tax: 2.5% of the sale price. The corporation's 2013 transfer-fee income matches that rate applied to that year's recorded sales.
• Board package: contract of sale, two years of signed tax returns, pay stubs, a written source-of-funds statement, bank commitment and recognition agreements if financing, references and credit checks. Guarantors submit the same financials as the applicant.
• Subletting: 30 days' notice to the board. The proprietary lease says consent to sublets under 12 months shall not be unreasonably withheld; the house rules add the 10% fee, two-year cap and three-apartment limit.
• Renovations and insurance: written board approval 30 days ahead, weekday hours, licensed trades, $1 million contractor coverage and a $1,500 deposit. Shareholders carry at least $300,000 of liability coverage naming the corporation.

Sales sourced from NYC Department of Finance recorded transfers (BBL 3-01081-0038). 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.

Confirm the debt position first. If the cooperative currently has no underlying mortgage, there is no maturity on an existing mortgage; that does not establish lower total maintenance or its capacity to fund a future project. Ask what the reserves are and how the next façade cycle will be paid for.

Budget the flip tax as the seller's cost, and your own later. The flip tax is 2.5% of gross price, and it will come out of your proceeds when you sell.

Take the sublet cap into account. With three apartments at most sublet at any time and a two-year limit, this is not an investment building. If you might need to sublet later, plan around those limits.

Lead with the floor and the exposure. In a four-line, six-story building, the floor number and which way the apartment faces are the first facts a buyer needs.

Have the finances ready. A satisfied mortgage, recent façade and boiler work, and an 80% financing ceiling are selling points with both buyers and lenders — have the most recent audited statements ready before the first showing.
