Final answer:
The incorrect statement about the online real estate services market is that their primary service is just listing houses; their influence extends to transforming the entire home buying process and offline behavior.
Step-by-step explanation:
Among the statements about the online real estate services market, the one that is not true is that the primary service offered by real estate sites is a listing of houses. While listings are a significant aspect of these services, the major impact has been the transformation of the home buying process and the influence on offline behavior, such as direct engagement with real estate agents and the viewing of homes. With the advent of the internet and e-commerce, these platforms have indeed created a revolution in the real estate market by making it easier for buyers to start their home search online, which has become the first step for nearly all ages of home buyers.
The improvement in communications technologies, including the development of the internet, has globalized and increased competition in many sectors, influencing not just retail but also business-to-business transactions. Similarly, in real estate, online platforms have made possible for wider audience access to property listings, comparisons, and information which were previously limited.
