Where should I keep my cash?

[Zack Welch]

I have recently inherited a triplex where I live in one unit and rent out the others. I would also like to start saving money to buy another property. So this is sort of a two part question: where should I put cash that I have set aside for expenses? (Should I invest it somewhere? Keep in savings account? Any other options?) also what should I do with the cash that I am saving to buy another property in a year or so from now?
