Schwab also offeres a interest bearing checking account that you could open but if you are looking for short term safety I would look at a California Tax Free Muni Bond Fund. You might find the liqudity is there, and you don’t deal with paying tax on it at the end of the year. This oftentime provides a higher overall yield. If it is just over a couple of years you are looking to keep your money in this type of account consider using a no load fund or consider C shares of a loaded fund. Good Luck
