If your landlord isn’t registered with HomeSwapper, you would need to register in the normal way and would then be given the optio to pay. By doing it this way, your landlord would not have any involvement in your account.
If you find a swap though, you would still need to apply to your landlord to process the exchange, so in the end it will be your landlord’s decision whether you’re able to do the swap.
