If you are saving for a home purchase and want something that does not carry risk; you should absolutely be in some 6 month / 1 year T bills. (US Treasury bills)

They are Government insured meaning the government guarantees you your investment back and they are giving 5% interest rates for borrowing your money.

You can use a ladder of bills, or lump into one. Your money will grow safely and that is something I am personally doing during a time when the markets are volatile or more riskier than I am willing to be with money for a home purchase.
