Yes! If you have Naborly Passport, once an Application has been submitted, you can edit the contents of your Application. If you have a membership, you can use the "Share Application" feature on your Naborly dashboard. This will allow you to easily recover your saved information and share your Application with the same (or different) landlord:
After you have accessed the share application button and enter your prospective landlord's email you will be able to Press Load Saved Information to re-populate your new Application with the information that was saved from your previous Application. From there, you can simply amend the error in your Application and submit.
If you have made an error in your Application and you do not have a Naborly Passport membership, you will not be able to edit/share your Application from your dashboard. Instead, you will need to request a new application from the landlord directly.
