You could always go with a CD. Many of my family members have done this in the past, and it works well. However, if you’re only going to let it sit for a year or two, it makes more sense to do a money market deal, through somebody like Charles Schwab, who pick the companies your money is invested in and (generally, afaik) guarantee a return rate. It’s not as good a return rate as risking your money on the market, but it’s better than just letting it sit in a bank.
