Landlords can now add itemized fees to their Zillow listings. These are charges that apply in addition to rent, such as pet rent, parking, HOA fees, and more. They'll display directly on Zillow, so prospective tenants have full visibility before they apply. This works for all property types, including multifamily.
To try it out, click on the "+ Add fee" link on the create listing screen.
That will add an itemized fee that you can customize.
The full Zillow listing process is detailed in the How to Post to Zillow from RentRedi help article.
