Best place to hold $30k for 4 - 8 months?

[Paul Henning]

Hello! We are moving from Port Angeles, WA to McAllen, TX and I am currently working on getting my family into a SFH home as a primary residence that will work as a rental when we inevitably move in a few years. Hopefully we can be in our new home before Thanksgiving.

For our next goal, I have a down payment for a small SF investment property sitting in the bank waiting to get used, but that won't be happening until early 2022 it seems, 6 months from now. 

Where would you stash this downpayment $30k so it hopefully gains a bit, but also wasn't too locked in or at risk? My bank said the CDs are at 0.02% and I had to ask if the rep was joking. 

Thank you!
