She uses expired listings to show the price below which the property won't sell.
All real estate listings have a time limit because they are only available for a limited amount of time. A listing becomes expired when that period of time has passed. An expired listing status is displayed as 'X' on the MLS® system. Every MLS® listing agreement has a term, during which the seller commits to marketing the house for a specific period of time.
The listing expires and the time period ends once that period has passed. According to the MLS® system's rules, listings must be up for at least 60 days; any less is really not enough time for a property to sell and isn't worth the trouble.
