My Mum has moved into a care home & I want to let my house & move into hers to provide extra money towards the fees. That way round should be the best financial deal, as hers would need a bit of work and she would have to pay higher rate tax if I let hers. She has given me the right to buy the house in her will and also made provision for the valuation if I move in during her lifetime, so I believe I can prove it's her wish that I do this (she has spent a lot of time persuading me to move in there when she was gone from it). She also wrote a note recently saying she wanted me to live there for free. I want to pay the profit from renting mine towards her fees, to ensure she can stay in the current home as long as possible, so I wouldn't be staying for free. Does anyone know if this is allowable by the OPG? Additionally, I share the PoA with a step-relative, who wants to sell the house (several to £5000 a year, joint in excess of that). I won't agree to sell the house unless we have to, but can they stop me moving into Mum's? Where do I go for professional advice? Would the OPG advise on this?
