Proof of Funds from bank

[Steven Price jr]

hey everyone i've just put a reo property under contract ,and found a cash buyer same day to wholesale the deal my plan is to do a double close but the realtor needs a POF letter
And let's just say my i not on good terms with the banks. should i notify the realtor and tell them i'm wholesaling the property with a cash buyer or should i get a POF letter from the cash buyer.
