Final answer:
Decisions regarding access to real estate listings are mainly made by local multiple listing services and property owners, with significant roles played by real estate brokers and affiliate licensees.
Step-by-step explanation:
Decisions about access to real estate listings are typically made by local multiple listing services (MLS). These entities serve as a central database for real estate listings, and membership or access can determine what listings an agent or broker can present to buyers. Additionally, the owners of the properties have a say in whether their properties get listed or not, as well as which platforms and services these listings appear on. However, it is worth noting that real estate brokers and affiliate licensees who take the listing also play a significant role in managing, advertising, and sharing these listings with potential buyers and within their networks.
When considering the broader market dynamics, the principles of a competitive market system such as buyers and sellers acting independently, being well-informed about market conditions, and having the freedom to enter or leave the market are important for a healthy real estate market. These conditions play a role in determining how access to listings is managed and can affect the visibility and sale of real estate properties.
