Yes I know the title looks like something pitched by a telemarketer, but this is a relatively easy way to make a grand or so a year with short-term money.
For you and the spouse/SO, open up 2 of these prepaid cards:
Then open the linked savings account for each card and deposit $5k to each.
Finally, set up an automated direct deposit (ACH push) from your bank/CU to each for $50 a month - you have to do this to get the promo APYs.
Note that there is a $3 fee/mo. for the Mango and a $2 fee/mo. for the Union Plus so your net interest won't be the full APY, but it's still around 5% net for all four accounts - Mango pays 6% and Union pays 5%. Also note that you don't have to be a union member for the Union Plus card.
You have to transfer money from the savings account to the card and then ACH it out back to your bank/CU to pocket the interest - you'll want to do this at least yearly because the promo APY only applies to the first $5k in each account. Also, these accounts are backed by First Bank & Trust and are FDIC-insured.
If interested in an extra ~4%, you can also get the Paypal Prepaid card which is linked to your Paypal account (backed by Bancorp and also FDIC insured), then open a savings account for that and deposit $5k. You can have 2 PP accounts per person, one personal and one business. This pays 5% on up to $5k but there is a $4.95 fee/mo. so it is not as lucrative as the first two above. Same deal as above, you have to transfer money via your PP account to/from the card and then to/from the savings account. But you don't have to do a monthly deposit to get the promo rate.
