Where to keep cash when not tied up in a private lending deal?

[Tim Rector]

I am starting out as a private lender for home flips. It may take 1-2 months to find a suitable home which meets all criteria based on my deal finders feedback. In the meantime my cash is sitting in my savings account earning .02% interest :( My question is for other private lenders, where do you keep your funds while waiting for the next deal? I am guessing where the money is stored needs to be easily liquidated in short order and not at risk of dropping in value.  I do have a Fidelity account where I could move the funds.  I could wire the funds directly from Fidelity when the funds are needed once a house comes available.
Looking for suggestions for where other private lenders keep their cash when waiting for disbursement.  I am guessing liquidity is a key.

Thanks.
