What defines a "common source information company" in real estate?

A "common source information company" in real estate is primarily defined as a supplier of information about properties. This type of company gathers and disseminates data on real estate transactions, properties for sale, market trends, and other relevant information that can aid real estate professionals and consumers in making informed decisions. This information can include historical sales, property assessments, and demographic data, making it crucial in forming a comprehensive view of the real estate market.

The other options do not fit this definition. A provider of legal advice is involved in the legal aspects of real estate transactions but does not supply property information. A brokerage firm is primarily focused on facilitating real estate transactions rather than just providing property data. A financial institution may handle funding and lending aspects related to real estate but does not specifically provide information about properties as its primary function.
