How will I be able to check that the listing has been updated?

On PropSpace you can check whether the listing has been updated or not by checking the listing updated date. It helps you to track the date on a which a listing was last updated.

The last updated date will be displayed on the listings as well as on the data table as shown below.

On the data table you can click on the field 'Updated' so that the listings get sorted in ascending or descending order based on the last updated date helping you to track the listings which was not updated recently.
