Hi gang,
I'm trying to help my mother, who is 85, invest the sale proceeds of her house (when it sells; not yet) in something that will get her about 3% yield to help pay for her living expenses. She wants to safeguard the principle, though, so that the kids inheritance doesn't disappear.

All I'm somewhat comfortable with is dividend stocks, but I'm afraid the principle isn't as safe as she would like. Stocks can go down!
I'm not particularly familiar with other forms of investment besides dividend stocks so I was hoping someone could point me in a direction.

Thanks!
RB
