initial security deposit - bank transfer or other methods

[Kosh Vokter]

How do you normally get the initial security deposit from a tenant? Getting ready to have tenants sign the lease in WA, is it okay to ask them to do a bank transfer before giving the keys after the lease is signed or is it advisable to get it in a different form - check or money order?

Does the security deposit have to be held in a separate bank account?

I require the deposit and first rent payment be paid in full and with certified funds (money order, cashiers check). After they occupy, I'll also accept personal checks and ACH.

This is non-negotiable for a deposit. Fir the first rent payment, I will accept any firm if payment IF the funds process prior to occupancy. If someone pays with a check, they can't move in until the check clears.
