My Grandfather recently passed away and has left his estate to my brother and I. His final wishes in the will are that we keep it available for my father to live in until he passes, and that any other funds from the estate (bank, car sale, etc) are to be kept for future maintenance/repairs to the house. His reasoning for this is that my father is very unstable financially and would quickly burn through all the money and be back to asking for money again, so it is a way of protecting my father and us.
My father has a wife in Thailand and would like to move out there this year, meaning this scenario would not help him. He is on disability currently but will be retired by this time. We would like to rent the house out and send him any profits from this monthly as a way to ensure that he has a reliable monthly income no matter what he does and that the house is available to him if he wishes to return at any point.
I have looked on the internet but it seems very unclear on how we would be taxed for this, or if we can even do it as we will not transfer ownership of the house to my father. My brother and I are already individually in the 40% tax bracket (but rent from this on top of that should not push either of us up to the 45% bracket.
Would we need to get the income 50/50 to ourselves and then send on to him in Thailand, or is there another way of doing this? Also if we do need to do it that way, will we get taxed again for sending him money? The house value is about £480k I would estimate.
Thank you for any advice
