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

- **This home**: $875,000
- **Median sold price**: $2,457,500
- **Difference**: -$1,582,500 (-64.4%)
- **This home, $/ft²**: $1,029
- **Median $/ft²**: $1,268

- **Middle half of those sales**: $2,220,000 – $2,496,250

Based on condo two-bedroom sales in Midtown West.

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

### How these sales were negotiated

- **Sale-to-list price**: 92.6% (5 sales)
- **Sold below asking**: 100% (5 sales)
- **Typical time to find a buyer**: 72 days (5 sales)
- **Typical time to close**: 94 days (5 sales)

Based on condo two-bedroom sales in Midtown West with the required listing and closing data. Sample sizes vary by metric.

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.

### Price trend

Median price per square foot, sales at 150 West 51st Street

| Year | Median $/ft² | Sales |
| --- | --- | --- |
| 2016 | $1,281/ft² | 4 (thin) |

| 2025 | $1,260/ft² | 18 |
| 2026 YTD | $1,166/ft² | 8 |

Based on recorded sales at 150 West 51st Street. 2026 is year-to-date.

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.

Sales data through June 2026.

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.

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 1010031289. 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.
