<human>: My mother has been acting as legal guardian for my grandfather, who suffers from dementia. In this capacity she has been liquidating his retirement funds to pay for his very expensive healthcare and living expenses. 

He has around $300k, almost entirely (>90%) in dozens of individual equities and equity funds. About 225k is in IRA accounts. No documentation exists regarding any strategy he may have had and he is not able to communicate what any strategy may have been. It looks to me that he treated investing as a hobby likely didnt have a clear investment plan. My mother has zero experience with investment funds and to this point has mostly been selling whatever isn't paying dividends at the time of sale. My own retirement funds are indexed, my investing interests trend towards "set it and forget it."

Any advice on how best to proceed with managing this portfolio? The primary aim is to make funds last as long as possible. My grandpa's health is very poor, but he could live for several years and his current expenses are about 80k/yr.

Should we cash everything in and switch to bonds? Should we get a consultation with a financial planner (I am very hesitant to do this)? Should we liquidate as needed proportional to portfolio composition or by weeding out underperforming stocks?

Any and all help is appreciated.
