Eligible buyers receive that Buyer Commission Share directly at closing to offset closing costs, down payments, or renovations. The figures below are illustrative, based on a **3% buyer-broker commission**; your share follows the commission offered on the transaction.

- **Contract Purchase Price**: $4,900,000
- **Illustrative Buyer Commission Share**: -$73,500*
- **Illustrative Net Cost**: $4,826,500

*Illustrative Buyer Savings of $73,500 — 50% of a 3% buyer-broker commission, shared at closing.*

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.

- **Median closed price**: $2,250,000
- **Middle half**: $2,120,000 – $2,725,000
- **Based on**: 3 three-bedroom sales at 100 UNITED NATIONS Plaza
- **Period**: October 2021 – April 2026
- **Median $/ft²**: $1,023/ft²

### Price trend

Median price per square foot for sales at 100 UNITED NATIONS Plaza, 2016 to 2026. 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 |
| --- | --- | --- |
| 2016 | $1,442/ft² | 5 |
| 2017 | $1,265/ft² | 10 |
| 2018 | $1,290/ft² | 8 |
| 2019 | $1,290/ft² | 8 |
| 2020 | $1,119/ft² | 6 |
| 2021 | $1,051/ft² | 15 |
| 2022 | $1,122/ft² | 15 |
| 2023 | $1,141/ft² | 7 |
| 2024 | $1,390/ft² | 4 (thin) |
| 2025 | $1,240/ft² | 6 |
| 2026 | $1,023/ft² | 5 |

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.
