It is my opinion that the law for security deposits in my state is not well written, as I get the impression that you feel that way about your state's law. My initial reading of my state's law gave me the impression that I needed an escrow account but I was having trouble setting one up. In my state the law says "All moneys paid to the landlord by the tenant as a deposit as security for performance of the tenant's obligations in a lease or rental agreement shall promptly be deposited by the landlord in a trust account, maintained by the landlord for the purpose of holding such security deposits for tenants of the landlord, in a financial institution as defined by *RCW (Revised Code of Washington)
30.22.041 or licensed escrow agent located in Washington." After much research I learned that what is required is that the money is to be deposited in one of three types of 0accounts:
1. Trust account
2. in an account in a bank recognized by my state
3. in an account with a licensed escrow agent.
So when I stopped referring to an escrow account then bank then understood what I was trying to do.
This may be where you are with your bank.
