Where do you keep your investment and reserve money?

[Adam Sporinsky]

When the investors here have cash saved up for down payment money on a new investment property, do you store that money in a standard bank account, in the market, in some other liquid investment?  Some combination of the above?

What about reserve cash, my assumption would be that most people keep reserve cash in a more stable account like a bank account or money market, but does anyone do things differently?  Especially for people who might store down payment money in the market or a less stable but higher interest vehicle.

Do people use one account per property, or one account for all of their properties and just manage the amount in it to cover reserve for all of the properties thy own?

What are the successful investors best practices for the cash they need to do business?
