## Property Overview

This extraordinary 25-foot-wide Upper East Side triplex residence lives like a private mini-townhouse—offering the size and scale of ~3,500 square feet within a boutique pre-war townhouse coop. Spanning the first two floors of the building plus a lower level space, this crown-jewel pairs timeless architectural presence with a rare 25-by-20-foot lushly landscaped private garden, creating an unparalleled indoor-outdoor lifestyle in the heart of Manhattan.
The parlor floor unfolds as the centerpiece of the residence, defined by soaring 11-foot ceilings, rich hardwood floors, and a wood-burning fireplace that anchors the living space with warmth and character. Expansive glass windows face directly the magnificent private garden – making it ideal for intimate evenings, elegant entertaining, or large-scale gatherings. The garden is beautifully maintained with a discreet automated irrigation system, ensuring year-round vibrancy.
Just beyond, the windowed kitchen blends warm granite countertops, classic wood cabinetry, stainless-steel appliances, and a vented hood, offering excellent storage and functionality. This level is thoughtfully arranged with a formal sitting room, dining area, media room, one bedroom, and a full bath—balancing gracious entertaining with comfortable daily living.
The upper-level features two generously proportioned bedrooms with en-suite baths, including a primary suite with walk-in closet, dressing area, and vanity station—providing serene and private quarters. A spa-like bath with steam shower enhances the retreat-like atmosphere.
A rare and valuable addition, the fully finished lower level offers exceptional flexibility for live-work, bonus space for staff, additional storage or otherwise.
It has a separate entrance, kitchen and bath; legally zoned for nonprofit or a doctor’s office, it conveys with the apartment.
Additional features include a 130-square-foot deeded storage room, in-unit washer and dryer, individually controlled air-conditioning units, and ceiling fans in every room. Polished onyx windowsills at street level add a subtle layer of architectural refinement throughout.
The pet-friendly cooperative offers low monthly charges and allows co-purchasing and pieds-à-terre with board approval on a case-by-case basis. Ideally situated just one block from Carl Schurz Park and Gracie Mansion, the home is moments from the Second Avenue subway, the 4/5/6 lines, neighborhood markets, and fine dining. For drivers, easy access to the FDR and convenient street parking complete the lifestyle appeal.

## Sales Evidence

### Recent closed sales

2 apartments at 517 East 87th Street have recorded sales since September 2021, the most recent for $2,475,000 in August 2026. Prices are the figures recorded with the City, not asking prices.

| Unit | Beds | Sq Ft | Sold Price | $/ft² | Sold | Source |
| --- | --- | --- | --- | --- | --- | --- |
| TRIPLEX (Apartment) | 4 | 3,500 | $2,475,000 | $707/ft² | August 18, 2026 | MLS |
| 4E (Apartment) | 2 | — | $675,000 | — | March 18, 2022 | City record · MLS |

Every row is a recorded transaction, including ancillary spaces such as storage and staff rooms where they were sold separately. Those are excluded from the benchmark below.

### How this price compares

The median closed price for comparable co-op four-bedroom sales in Upper East Side is $3,862,500, based on 31 sales between September 2024 and June 2026. This home is asking $2,475,000, $1,387,500 below that median. The middle half of those sales closed between $2,975,000 and $5,175,000.

- **Median closed price**: $3,862,500
- **Middle half**: $2,975,000 – $5,175,000
- **Based on**: 31 co-op four-bedroom sales in Upper East Side
- **Period**: September 2024 – June 2026

Square footage is recorded for only 14 of these 31 sales (45%), so no price per square foot is shown for this group. Co-op sales rarely carry a floor area, and a figure drawn from a handful of them would not describe the rest.

Across the 29 of these sales with a published asking price, the median closed at 93.7% of what it originally asked. 79% of them closed below the original ask.

This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Upper East Side instead.

### How these sales were negotiated

- **Sold vs original ask**: 93.7% of the original ask
- **Closed below ask**: 79% of 29 sales
- **Listed → in contract**: 80 days (about 11 weeks)
- **In contract → closed**: 115 days (about 16 weeks)

Across the 29 of these sales with a published asking price, the median closed at 93.7% of what it originally asked. 79% of them closed below the original ask.

Half of these homes were in contract within 80 days (about 11 weeks) of coming to market, based on the 29 with a recorded listing date.

Once a deal was agreed, closing took a further 115 days (about 16 weeks), based on the 29 with both dates recorded. A co-op board package and its interview account for much of that.

These are two separate periods measured on different clocks — time to find a buyer, and time from agreed deal to closing. They are medians of different sets of sales and do not add together into a single "days on market" figure.

Based on 31 co-op four-bedroom sales in Upper East Side, September 2024 – June 2026. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ.

### Price trend

Median sold price for co-op four-bedroom sales in Upper East Side, 2017 to 2025. The series is held to one bedroom count and one ownership type for the same reason: an unfiltered median tracks which apartments sold, not what they were worth.

| Year | Median sold price | Sales |
| --- | --- | --- |
| 2017 | $6,431,250 | 15 |
| 2018 | $5,600,000 | 13 |
| 2019 | $5,200,000 | 15 |
| 2021 | $3,238,500 | 19 |
| 2022 | $5,475,000 | 24 |
| 2024 | $3,200,000 | 19 |
| 2025 | $4,225,000 | 18 |

This building does not have enough sales with a recorded floor area to chart its own price per square foot, which is usual for a co-op. The series above follows comparable homes across Upper East Side instead.

Sale prices are the consideration recorded with the City in ACRIS, and each sale is dated by the day the City recorded it. A closing date reported to the MLS typically falls one to two weeks earlier. Recorded sales describe what has already happened and are not an appraisal, a valuation, or an estimate of what this home will sell for.
