The Best Sources of Real Estate Data in 2023

Artificial intelligence and machine learning are beginning to have a major impact on the real estate industry. Less than a decade ago, real estate professionals had few options for leveraging predictive analytics technology, let alone securing quality real estate data. Now there are products to automatically extract data from documents, pull various property data sources together and even predict investment performance. These advancements have brought more investors into the market and made the industry more competitive than ever.

Access to high-quality data may be the most important factor for success in today’s competitive real estate investment market. It allows real estate professionals to understand the wants and needs of prospective residents, facilitates more accurate valuations, and leads to smarter investment decisions. By leveraging predictive analytics with quality data, real estate investors, developers and brokers can forecast demographic and economic changes, identify underserved markets, and optimize value-add and development strategies.

In 2023, there are so many sources of real estate data available that it can be hard to determine the best data providers for your needs. The team at has been working with demographic, economic, rent and property valuation data sources for many years, so we put together a list of sources for real estate data that everyone in the industry should be familiar with. We break the data sources into four categories:

  1. Property Ownership & Assessor Data – These include data on the current owner of the property, what they pay in taxes, lot sizes, approved uses and building materials are characteristic of these sources.
  2. Commercial Real Estate Data – These sources include rent and transaction data on multifamily apartments, hotels, offices, retail and industrial properties. Attributes such as building size, rent per sqft, last sale price and current tenants and lease terms are typical from these sources.
  3. Single-Family Housing Data – These data sources provide detail on listing and sales prices and trends, absorption rates, listing descriptions, floorplans and tons of property photos.
  4. Demographic & Economic Data Sources – Includes data aggregated from sources like the U.S. Census and American Community Survey, as well as proprietary data from surveys of local business owners and field research.
