To edit the lease, login to your Zillow Rental Manager. Navigate to the lease tab, first click View lease and then Edit on the top right corner of the lease. If the lease is pending signatures, it can be edited. However, editing the lease will pause the signing and cancel any existing signatures. The lease will need to be sent for signatures again after the edits are made.
Once a lease is signed and active, it cannot be edited. If you would like to add an addendum to the lease on Zillow, you will need to start a new lease and send it out for signatures. Or, add an addendum to the lease offline and connect with your tenants about the update to the lease outside of Zillow.
