Report Incorrect or Missing Data

The data you see on PropertyShark is aggregated from public sources, such as local county clerk or tax assessor offices. These agencies provide information in bulk; we do not verify it or correct it before publishing.

Why You Might See Incorrect or Missing Data

1. Data Recorded Incorrectly with Government Agencies

Errors such as typos, spelling mistakes or incorrectly entered numbers may originate at the source. Because we don’t alter data, only the original agency can correct these errors. If you notice such mistakes, contact the relevant government office (for example, the County Clerk or Tax Assessor). In NYC, multiple agencies handle different property information (sales, assessments, violations, permits).

2. Data Not Made Available to PropertyShark

We rely entirely on local authorities. Some regions may delay sharing data, provide incomplete records, or choose not to publish certain data sets. Coverage varies dramatically by state and county. For example, there are five states/territories where we currently have no coverage: Montana, North Dakota, South Dakota, Puerto Rico and Wyoming. Check coverage here.

3. Possible Delays with Recorded Information

Government recording and release of information aren’t always immediate.

• Example: in the five boroughs of NYC, a sale may take up to two weeks; in Nassau or Suffolk counties up to one month; in some states even several months. For ownership data, we use the Annual Assessment Roll (which updates once a year in many regions), and we update ownership when deeds become available.

4. Information Was Suppressed

Some properties may show very limited information because the data has been suppressed at the request of the owner or the agency. When the original source removes a record, we remove it too.

5. Issue with PropertyShark

While rare, human or system errors at our end can happen. If you believe the data shown is incorrect and none of the above explanations apply, please contact us.

How to Report an Issue

If you believe a specific property’s data is incorrect or missing, here’s how to proceed:

• Provide the property address (including city/state/ZIP)

• (Optional) Attach a screenshot of the issue or document from the public record
• Submit a support request or call (718) 715-1758 (Mon-Sat, 9 a.m.–5 p.m. ET).
