Sallie Mae Bank is paying 1.05 percent on money market accounts. The transfer process is simple. Ally is at 0.95 percent on both savings and money market accounts. Also simple. Sadly, TIAA Direct discontinued accepting applications for its 1.25 percent account.
The other option is to find a credit union that offers a high yield checking account in your area. Here in the Bay Area, Provident offers 2.01 percent up to $25,000, as long as you have one ACH transaction and 10 debit transactions per month.
I would not put short term money in a bond fund. Too much risk to principal.
