National Data Collective (NDC), is a property data source geared towards keeping you successful with its
unique combination of data and search tools not available through other data providers.
NDC was first formed in 1998 by a real estate appraiser as a tool for appraisers to quickly find and access
property data to use in their reports. Since then, NDC has been providing appraisers and other real estate
professionals with a comprehensive collection of public record data, maps, and search tools in a user-friendly
web format. With years of development and user feedback on our side, NDC has aggressively grown into a
multi-use data company that specifically serves the needs of appraisers and real estate professionals.
