📊 Why this data is more reliable than other sites

The numbers on this page come from the NYC Department of Finance public records — every legally recorded property sale in Old Mill Basin, not just MLS-listed transactions. Sites like Zillow and StreetEasy only capture listings that go through their platforms, missing FSBO sales, off-market deals, and transfers that never hit the MLS. This dataset includes all of them.

We also remove bulk portfolio transfers, nominal sales, and non-arms-length transactions that would distort median prices — cleaning that most data sources don't do. The result is a more accurate picture of what individual homes are actually selling for in your market.

Data source: NYC Department of Finance, Rolling Sales Data — Brooklyn. Period: March 2025 – February 2026. Excludes $0 transfers, nominal sales, non-arms-length transactions, and bulk portfolio transfers identified through same-date/same-price pattern analysis. Last updated: April 2026.

Takeaway for Sellers

Old Mill Basin sees its strongest closing activity in January, March and April, September and November — the months highlighted in orange above. These peaks indicate when buyer demand is highest and the most transactions close.

Since the typical sale takes 3 months from listing to closing you should be listing approximately 3 months before these peak windows to position your home when competition among buyers is strongest.

The optimal listing date depends on your property type, your timeline, and current inventory levels. A strategy session can pinpoint the right window for your specific home.
