A Private Pricing Opinion — what your apartment at 1825 Riverside Drive 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.
Riverside Drive ends in Inwood, and the six-story prewar houses at Dyckman Street are its last stretch of apartment buildings. This block has five of them on the drive, at 1781, 1793, 1795, 1803 and 1825, plus a house of worship at 1815. City records classify three of the five as cooperatives and two as rentals. 1825 is the northernmost.
It is an ordinary market-rate cooperative. The sponsor converted it in 1984, and apartments have traded to unrelated buyers through share transfers ever since. It does not hold the regulatory agreement or income restrictions of an HDFC, which some Upper Manhattan co-ops do.
What sets it apart from larger Upper Manhattan cooperatives is size. With 42 apartments, board decisions, assessments and the sponsor's remaining position all weigh more heavily per apartment than they would in a 200-unit complex.
Architecture and unit composition
The building fills a lot of about 13,400 square feet with roughly 57,800 square feet of floor area, per PLUTO. That works out to an average of about 1,375 gross square feet per apartment. Layouts run from studios to four-bedrooms, per listing records, with a courtyard at the center. The design is 1920s Upper Manhattan work: brick, a courtyard plan, and apartments sized generously for their era.
Building operations
Underlying mortgage. ACRIS records a consolidation of the corporation's mortgage with a commercial bank in April 2021, totaling $1.2 million. That is roughly $29,000 per apartment, which is modest. The public index does not show the rate or maturity. Get both from the most recent financial statements.
Tax benefits. The Department of Finance's historical J-51 file shows two small abatement grants on the lot. One started in 1995 and was used up by the 2005 tax year. The other started in 2004 and ran through 2014. Neither is still in effect, so no J-51 expiry is coming. The current roll carries the standard cooperative abatement plus individual owners' personal exemptions, which are passed through the corporation.
Staffing. A live-in superintendent, per listing records.
Recent sales
1825 Riverside trades as Inwood prewar co-op stock and is priced per room. Price differences come mainly from apartment size, floor, whether the unit faces Riverside Drive, and how recently it was renovated. The largest renovated apartments set the building's high end, and estate-condition units trade at a clear discount to them. ACRIS shows sales by a holder of unsold shares running from 2007 to 2024, so some recent comparables are sponsor sales and not resales between owners. Separate the two before comparing. Unit-level transaction history is maintained in The Roebling Research Library and shared with clients during diligence.

Sales sourced from NYC Department of Finance recorded transfers (BBL 1-02246-0110) and verified listing data. Apartment-level facts (line, condition, asking-price context) curated and cross-verified by The Roebling Team research desk. Not all transactions cross-verify with ACRIS records — sponsor and LLC purchases sometimes record at stipulated values rather than market price.

What to know if you’re buying
Board package and interview. Expect a full co-op board package and an interview. The managing agent sets the requirements for income, debt-to-income, and post-closing liquidity, meaning the cash a buyer must still hold after closing.
Ask about the sponsor's position. A holder of unsold shares was still selling apartments in 2024. Find out how many apartments it holds, whether they are rented, and whether its maintenance is current. With 42 apartments, even a handful of sponsor units affects board control and the corporation's finances.
Get the policy stack in writing. Flip tax, sublet rules, pied-à-terre use, and trust or LLC purchases are not documented publicly. Get them from the managing agent before you bid.
What to know if you’re selling
Confirm the flip tax and the financing ceiling before you list. Both shape your net proceeds and the size of your buyer pool, and neither is on the public record.

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.
