My elderly dad is widowed and currently lives about an hour and a half away from me and DD in his house, which he owns outright. Due to personal circumstances, I have never bought a house and currently rent. Recently Dad and I have been discussing the possibility of his selling his house and buying one in the town where DD and I currently live, and for us all to live there together. Is this possible , or is there anything dodgy about it financially or legally- for example, if my dad passes away soon after we all move in together?
