<prompt> Human: I am seeking advice for my parents. They are looking to sell their house, which would give them 340k in cash. They no longer need a big house as all us kids have moved out and started careers. What would be a good and stable use of 200k? This money would not be needed for about 15 years. They currently have no retirement, as my father was not very smart financially till recent years. So i am trying to find a way to set them up for the end of life. I have done some research, but nothing has really stuck out as a good option. I want to find something that is pretty stable without a ton of risk, which i know means less return.  <response>: It depends on what they are looking for. If they dont trust themselves to invest it properly, a single premium annuity may be worth looking into - this trades the lump sum for monthly payments for life. That plus social security may be enough for them to live on.Otherwise, a lazy portfolio with a large bond percentage may work if they want the possibility of higher returns in exchange for higher risk.
