If the tenant is paying half the rent to a non-live in landlord, wouldn't that need to be RTB registered? I think you're playing a risky strategy cherry-picking elements from rent-a-room-relief and tenancy legislation as suits your own purposes.With regard to tax, why would I include full rent in my returns. I receive half. I don't know what, if anything, that he is declaring and if I did, I would not discuss his tax affairs as that would be out of order.
Are these tenants really paying half the rent to you and half directly to your brother?
