If you have already logged a bond with the RTBA, there isn't a guarantee that you'd be able to use Bondable on your existing tenancy. We would recommend following these steps:
1. Get in touch with your property manager / rental provider to see if they would be willing to assist with getting your bond refunded from the RTBA with a bond guarantee in its place
2. If they are happy to assist, subscribe to Bondable here: https://app.bondable.me/signup
3. Your property manager / rental provider will automatically be sent the Bond Guarantee once you've signed up, at which point either party may request a refund of your bond from the bond authority.
If your property manager / landlord / rental provider is not willing to follow the above process, you won't be able to use Bondable for your current property. Be sure to keep Bondable in mind if you move to a new property.
