It is up to the Landlord/Property Manager who applies to their property, so they will need to invite your co-applicant(s) to apply. In order to get a new Application for your co-applicant(s), you will need to contact the Landlord/Property Manager directly with this request.
We'd also strongly recommend that you and your co-applicant(s) use different email addresses to complete the Naborly Application, as only one applicant's information can be saved per account. When you make this request to your prospective Landlord/Property Manager, you should provide them with your co-applicant's email address.
