A newly posted pre-market listing is active for a certain period of days or hours (depending on your association's business rules) and it cannot be extended beyond the auto-expiration date unless it is linked to an active on-market listing (a listing with an MLS ID#).
Pre-market listings automatically expire and will be automatically removed from both your association's view & public view.
Not to worry though, you will always receive an email notification 24 hours before your listing expires. You will also receive an email notification the day your listing expires.
In-platform notifications are also a great reminder for you to update your pre-market listings as well.
