## Sales Evidence

### Recent closed sales

8 apartments at 521 Dean Street have recorded sales since September 2021, the most recent for $690,000 in October 2025. Prices are the figures recorded with the City, not asking prices.

| Unit | Beds | Sq Ft | Sold Price | $/ft² | Sold | Source |
| --- | --- | --- | --- | --- | --- | --- |
| 2 (Apartment) | 1 | — | $690,000 | — | October 23, 2025 | City record · MLS |

| 1 (Duplex) | 1 | — | $510,000 | — | February 12, 2025 | City record · MLS |
| 7 (Apartment) | 2 | — | $950,000 | — | August 5, 2024 | City record · MLS |
| 5 (Apartment) | 2 | — | $851,000 | — | July 17, 2023 | MLS |
| 2 (Apartment) | 1 | — | $680,000 | — | September 13, 2022 | City record · MLS |
| * (Single Family Residence) | 6 | 3,696 | $4,999,999 | $1,353/ft² | June 24, 2022 | MLS |

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 two-bedroom sales at 521 Dean Street is $925,000, based on 3 sales between August 2024 and March 2025. This home is asking $1,199,000, $274,000 above that median. The middle half of those sales closed between $912,500 and $937,500.

- **Median closed price**: $925,000
- **Middle half**: $912,500 – $937,500
- **Based on**: 3 two-bedroom sales at 521 Dean Street
- **Period**: August 2024 – March 2025

Square footage is recorded for only 0 of these 3 sales (0%), so no price per square foot is shown for this group. Co-op sales rarely carry a floor area, and a figure drawn from a handful of them would not describe the rest.

Across the 3 of these sales with a published asking price, the median closed at 100% of what it originally asked. 33% of them closed below the original ask.

### How these sales were negotiated

- **Sold vs original ask**: 100% of the original ask
- **Closed below ask**: 33% of 3 sales
- **Listed → in contract**: 77 days (about 11 weeks)
- **In contract → closed**: 68 days (about 10 weeks)

Across the 3 of these sales with a published asking price, the median closed at 100% of what it originally asked. 33% of them closed below the original ask.

Half of these homes were in contract within 77 days (about 11 weeks) of coming to market, based on the 3 with a recorded listing date.

Once a deal was agreed, closing took a further 68 days (about 10 weeks), based on the 3 with both dates recorded. A co-op board package and its interview account for much of that.

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 3 two-bedroom sales at 521 Dean Street, August 2024 – March 2025. Each figure counts only the sales that recorded the dates it needs, which is why the denominators differ.

### Price trend

Median sold price for co-op two-bedroom sales in Prospect Heights, 2019 to 2024. The series is held to one bedroom count and one ownership type for the same reason: an unfiltered median tracks which apartments sold, not what they were worth.

| Year | Median sold price | Sales |
| --- | --- | --- |
| 2019 | $947,500 | 16 |
| 2020 | $862,500 | 10 |
| 2021 | $1,085,000 | 18 |
| 2022 | $866,000 | 15 |
| 2024 | $1,397,164 | 11 |

This building does not have enough sales with a recorded floor area to chart its own price per square foot, which is usual for a co-op. The series above follows comparable homes across Prospect Heights instead.

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.
