Firstly note that the power of attorney ends on death and the executor takes over. If the will states that you get a share of the house then that is what you get only if the house is still there on grandmothser's death. If it has been sold then the money would go to whoever the will says, or to the residual beneficiaries, is, those who inherit the estate other than specific beneficiaries. You are a specific beneficiary only if the specifi item of estate still exists at the date of death. I hope that helps. If it is your grandmother's intention to leave you the money from the sale of the house is sold then her will should specifically say so. Happy to discuss further.
