If you’re looking short term a timed cd for your period is fine but with the fed raising your online brokerage money market is gonna likely be better. Just bcuz you’re not talking a huge soread and with a cd u lose flexibility.
Not sure how much he has. But other options.
Short term muni bonds…can get 3% tax free but what’s the bracket and how much does he have and define short term. 3 years ? 10 years ? At 12 years u can get 4% lending to Illinois…and no they aren’t going broke. That’s 4% tax free.
And if your ballsy but you can’t protect principal. But let’s say u have $5k. Put into 10 blocks. Buy high dividend highly deflated stocks like intel. Verizon. AT&T. Get dividends for interest and u may make money too. But that’s the problem. U may also lose it :). Kidding on that one but u can gain income. But it’s not for safe money. Lots of 5%+ dividends on solid companies tho.
He must have decent coin since u said u did the I bonds. Take the online money market and don’t look back. If they have a short term cd at a slightly higher rate…like 3 mos…u could do that but lose flexibility for probably just a few bucks.
Good luck.
