If we are receiving your listings from a feed (i.e. Realty MX, Nestio, ORL, etc), they will only appear on your agent page. Your agent page can be set up and managed from your account settings.
Only listings that are posted directly using Zumper's posting tool appear in the listing section of your dashboard.
You will need to manage your listing directly from the source they are posted originally from. Please note it takes about 24-48 hours for your information to update.
