## Property Overview

Perched high above the Upper West Side, Residence 12C at 378 West End Avenue is a beautifully proportioned home with nearly 12-foot ceilings, private outdoor space, gracious entertaining rooms and expansive southern light overlooking the landmarked Collegiate Church.

A private elevator vestibule opens into a formal gallery, setting the tone for a residence that feels both elegant and welcoming from the moment of arrival. The great room is exceptionally wide and beautifully proportioned, offering impressive scale for both everyday living and entertaining, while oversized windows frame open southern exposures and beautiful natural light throughout the day.

Thoughtfully reconfigured, the home is currently set up as an expansive three-bedroom plus den residence, with the original fourth bedroom opened to create a dramatic entertaining and living area. The original four-bedroom layout can easily be restored, and both floor plans have been included for reference.

The open kitchen, custom designed by Christopher Peacock and outfitted with Wolf and Sub-Zero appliances, is thoughtfully configured to balance openness with separation, allowing for both casual living and more formal dining occasions. Extensive storage and generous workspace make it as functional as it is beautiful.

The bedroom layout is ideally winged for privacy and flexibility, with all bedrooms featuring ensuite baths. A discreetly positioned powder room is tucked away off its own vestibule. The corner primary suite enjoys coveted north and east exposures along with a luxurious ensuite bath and abundant closet space.

Additional features include central air conditioning, excellent storage throughout and two private storage units that transfer with the sale.

The sellers would also consider selling their parking space separately. With only nine parking spaces in the building, this presents an exceptionally rare opportunity for purchasers seeking the convenience of on-site parking.

Residents of 378 West End Avenue enjoy an extensive suite of amenities including a 75-foot lap pool, fitness center, basketball and squash courts, music practice and recording rooms, residents' lounge, reading room, children's play spaces, private garden, movie room and on-site garage access.

Showing the 40 most recent of 59 recorded sales in this period.

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 four-bedroom sales at 378 West END Avenue is $8,155,996, based on 18 sales between April 2022 and April 2025. This home is asking $8,750,000, $594,004 above that median. The middle half of those sales closed between $7,712,500 and $8,417,500.

- **Median closed price**: $8,155,996
- **Middle half**: $7,712,500 – $8,417,500
- **Based on**: 18 four-bedroom sales at 378 West END Avenue
- **Period**: April 2022 – April 2025
- **Median $/ft²**: $2,664/ft²

### How these sales were negotiated

- **Listed → in contract**: 1 day
- **In contract → closed**: 112 days (about 16 weeks)

Half of these homes were in contract within 1 day of coming to market, based on the 16 with a recorded listing date.

Once a deal was agreed, closing took a further 112 days (about 16 weeks), based on the 15 with both dates recorded.

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 18 four-bedroom sales at 378 West END Avenue, April 2022 – April 2025. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ.

### Price trend

Median price per square foot for sales at 378 West END Avenue, 2022 to 2024. Price per square foot is used rather than sale price so the line follows the market rather than whichever apartments happened to change hands that year.

| Year | Median $/ft² | Sales |
| --- | --- | --- |
| 2022 | $2,764/ft² | 36 |
| 2023 | $2,756/ft² | 12 |
| 2024 | $2,615/ft² | 4 (thin) |

Years marked "thin" rest on fewer than 5 sales, where a single unusual apartment moves the median a long way. Read those points as the small samples they are rather than as the market turning.

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.

## Property Tax History

Taxes at 378 West End Avenue #12C were $76,824 in 2026, up 3.8% from 2025.

| Year | Tax Assessment | Land | Additions | Billable Value | Property Tax | Tax Rate |
| --- | --- | --- | --- | --- | --- | --- |
| 2026 (FY 2026/27) | $678,086 | $55,601 | $622,485 | $614,595 | $76,824 | 12.5% (estimated) |
| 2025 (FY 2025/26) | $651,519 | $55,601 | $595,918 | $592,252 | $74,032 | 12.5% (estimated) |
| 2024 (FY 2024/25) | $612,815 | $55,601 | $557,214 | $575,224 | $71,903 | 12.5% |
| 2023 (FY 2023/24) | $564,191 | $55,601 | $508,590 | $564,191 | $70,535 | 12.502% |
| 2022 (FY 2022/23) | $382,025 | $55,921 | $326,104 | $380,238 | $46,644 | 12.267% |

The City has not published the official FY2026/27 and FY2025/26 tax rates yet. We calculated the tax for those years using the prior year’s rate, so treat them as an estimate rather than a figure the City has adopted. Every rate without the Estimated marker is the published one.

Tax Assessment is the assessed value on the City’s roll, and it is the figure other listing sites publish. It is not what the bill is calculated on. New York phases assessment changes in gradually for some tax classes, so the City bills the Billable Value shown beside it, less any exemption the owner holds. It usually trails the assessment, and it can sit above it for a few years after an assessment falls.

Figures are the New York City Department of Finance assessment roll for tax lot 1011691347. Assessed and billable values are determined by the City for tax purposes and are not an appraisal or an estimate of market value. Tax classes and rates are set annually and can change.
