To list your rental, click on the "List your rental" link at the top-right of the homepage.
Here, you'll want to toggle to the "Log in to Zillow Rental Manager" tab to start the listing process.
Once you've listed with Zillow Rental Manager (ZRM), your listings will syndicate to HotPads, Trulia, and Zillow! You can always access your listings through ZRM to view and edit your listings. You also have the ability to view leads, analytics, applications, and payments.
Note: Both HotPads and Trulia are Zillow Group owned companies.
