This building has not had enough comparable sales of its own in the period to support a median, so the benchmark is drawn from Flatiron instead. ### How these sales were negotiated - **Sale-to-list price**: 95.2% (45 sales) - **Sold below asking**: 89% (45 sales) - **Typical time to find a buyer**: 103 days (46 sales) - **Typical time to close**: 61 days (46 sales) Based on condo two-bedroom sales in Flatiron 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 sale price, condo and house two-bedroom sales in Flatiron | Year | Median sold price | Sales | | --- | --- | --- | | 2017 | $4,473,002 | 46 | | 2018 | $2,525,000 | 28 | | 2019 | $2,775,000 | 18 | | 2020 | $2,270,000 | 11 | | 2021 | $2,225,000 | 32 | | 2022 | $2,710,000 | 42 | | 2023 | $2,732,500 | 24 | | 2024 | $2,705,000 | 24 | | 2025 | $2,600,000 | 23 | | 2026 YTD | $2,750,000 | 23 | Based on recorded condo and house two-bedroom sales in Flatiron. 2026 is year-to-date.
