<prompt> Human: First time poster here. My grandfather is looking into adjusting his will to make sure that my mom doesnt end up with a lump sum of cash when hes gone as shes financially irresponsible. Ive looked into annuities and Vanguard funds, but not sure which is best option. Dont want to be managing distributions myself and want to make sure there is some flexibility to use funds if needed for medical reasons. Will likely have 200-250k to work with. Mom is 60 and Im assuming disbursement would need to be 2-2.5kmo to cover her monthly nut. Appreciate any help here.  <response>: Key concern I would have is who the trustee will be. You? Welcome to the world of headaches. A corporate trustee? Youre going to be paying a fixed percentage annually most likely, even further lowering her payouts. Be careful if you accept any kind of responsibility here, as this is a massive cluster in the making.
