What to do with 100k cash?

[Robert M.]

I'm having a tough time finding returns on our money and have thought about the funds in a money market with Charles Schwab. A little research discovered a Money market with Schwab(SWVXX) that pays 2.05%. I need the money accessible in case I find an investment property with a cap rate of 8% or higher. However, I believe that could be one or more years out. Does anyone have any other ideas or suggestions? Roths are maxed out, all debt is paid off except one rental which is at 3.9% fixed 20 years with 100k debt and 340k RMV. I don't know what to do with the cash, and any advice would be appreciated.

Thanks
