PropertyShark is a real estate data and research platform focused on helping users investigate residential and commercial properties, particularly across New York City. Drawing on more than 2,000 authoritative and vetted data sources, the service brings property records, ownership information, sales and financial history, maps, and market research tools together in one place.

Users can search by address or location, generate property reports, build and manage property or mailing lists, save searches, and compare similar sales to assess values. The platform also provides information on owners behind LLCs, researched contact details, mortgages, taxes, liens, title documents, permits, violations, zoning, development, and property risks. Its foreclosure tools cover pre-foreclosures, foreclosures, bank-owned properties, and auction results, with updates daily.

PropertyShark serves investors, residential and commercial brokers, developers, homebuyers, appraisers, insurance agents, contractors, journalists, and researchers. Customers can start with a free sample report, then purchase individual reports or choose among subscription plans. The company also offers real estate learning resources and customer support.
