Any person, firm, or corporation that is a source, compiler, or supplier of information regarding real estate for sale or lease is known as what?

The correct answer is a common source information company. This term refers to entities that collect, compile, or disseminate information concerning real estate listings, sales, or leases. They provide valuable data to real estate professionals, buyers, and sellers, making it easier for these parties to access and evaluate properties in the market. Common source information companies include Multiple Listing Services (MLS) and real estate databases that aggregate property information from various sources, helping to enhance transparency and access to real estate information.

Brokerage refers to businesses or firms that facilitate the buying, selling, or leasing of properties, but they are not strictly focused on the sourcing or compilation of information. Dual agency and designated agency are terms related to how agents represent clients in transactions rather than describing entities focused on information compilation regarding real estate. Therefore, these terms do not address the question of who compiles and provides real estate information.
