My brother and I are set to inherit a house from our uncle who died. The house is very valuable and there will be a sizable tax bill, even after the threasholds. As my brother already lives there, he wishes to continue to. He has offered to pay my share of the tax bill (as I cant afford it) so he can stay in the house for at least seven years, rent free, then we would come to another arrangement. For tax purposes , would this be a gift?. It comes to around 70k, so about 10k per year.
