Realtor.com is a third party website. The way ADDvantage works is to first put your listing in your local MLS. This takes about one day (weekday) or if submitted over the weekend, then in by Monday. Once your MLS listing goes live in the MLS, ADDvantage sends an automatic email notifying you that your listing is live in the MLS. As well, you can use this email verification to edit your listing. Typically it takes 24-48 business hours after you have received this email notification (we call email verification) for your listing to appear in Realtor.com.
Realtor.com is not a “real time” data feed but rather a secondary website to the MLS. It propagates data on weekday evenings. The same holds true for any changes made to your MLS listing. If you change your price on Wednesday, the change is made on the MLS that same day. However, Realtor.com may take an additional 24-48 hours to re-propagates the new change.
