- **Contract Purchase Price**: $2,000,000
- **Illustrative Buyer Commission Share**: -$30,000*
- **Illustrative Net Cost**: $1,970,000

*Illustrative Buyer Savings of $30,000 — 50% of a 3% buyer-broker commission, shared at closing.*

### Price trend

Median price per square foot, sales at 100 Riverside Boulevard

| Year | Median $/ft² | Sales |
| --- | --- | --- |
| 2016 | $1,309/ft² | 3 (thin) |

| 2025 | $1,314/ft² | 16 |
| 2026 YTD | $1,377/ft² | 10 |

Based on recorded sales at 100 Riverside Boulevard. 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 September 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.
