Your profile is what the landlord sees when you send a contact request. Therefore, it is essential that you fill it in carefully and enter all the relevant information.
In your profile, you can tell landlords about yourself, your housing situation, and your interests. A profile picture helps the landlord connect an application with a face.
Your profile shows your Reference Certificate, and what type of homes you've applied to.
Make sure that you add your references from previous landlords and employers if you have them.
