Final answer:
A listing that is not available for showing or sale until a later date is known as a Coming Soon Listing.
Step-by-step explanation:
A listing that is NOT available for showing or sale until a later date is a: Coming Soon Listing. This type of listing is announced to potential buyers as being available in the near future, but it is not yet ready to be shown or sold. This strategy can be used to generate interest and anticipation among buyers. A Coming Soon Listing differs from a Pocket Listing, which is kept off the market and sold privately by an agent, and both Open Listing and Net Listing, which refer to different types of agreement between a seller and an agent regarding how a property will be sold and how the agent will be compensated.
