You want the reward. Can you stand the risk?
You might consider an ultra-short-term bond mutual fund. Using Vanguard's Ultra Short Term Bond Fund Admiral Shares [VUSFX] as an example, it has shown greater than 2% total returns per year in 1, 3 and 5 year histories.
What about risk? If someone bought and sold VUSFX at the worst possible times in the disaster that was 2020, buying at the high in early March and selling at the low of early April, they would have lost about 1.8%. Can you afford to lose $1800 of your $100K if you have similar bad timing?
Yet even with that risk of loss for a forced sell-off after a very short term ownership, VUSFX had a total return of 2.02% for the full year 2020. If you will be holding the funds for at least a few months, your risk of loss is minimal, though not zero risk.
Vanguard warns investors that VUSFX is not to be used as a substitute for an insured money market account. So go in with your eyes open and understand the risks. Then reap the rewards if the risk is tolerable.
VUSFX pays dividends monthly which are taxable as ordinary dividends just like interest.
