Washington State Trust Account For Security Deposit?

[Kale Wilsford]

Hi everyone, 

My wife and I are preparing our first rental in Washington State. I know WA law mentions that the security deposit must be held "in trust."  My understanding is that the account must be an escrow type account. I spoke with the lawyer that reviewed my lease and he seemed to concur. 

The attorney stated that, "any bank should know what that is and be able to create one for you." However, I cannot find a bank that creates this account, I tried applying for an escrow express account with Capital One but they do not do open these accounts for businesses in WA. 

Am I mistaken on the type of account required? If not, can anyone recommend a financial institution?

Thank you for the help,

Kale
