If you're looking for available properties and wish to filter your results by possession date, simply add the Possession Date filter to your search, which is located under the Add a Field option.
Add a Field is located at the end of your filters.
TIP: For the Consumer and Map layouts, you will find Add a Field under More Filters.
For the Table, Map + Table and Map + Card layouts, Add a Field is located at the bottom of the filter menu.
Once you have applied the Possession Date filter, you can use the date fields to specify the date range you wish to include in your search.
