Wholesaling Bank Owned Properties

[Prince Conley]

I came across a good list of banked owned properties with majority of them having tenants already in place. The bank is selling however I came across the properties through a broker who represents the bank. I'm looking to possibly send the properties to a few investors but I'm still unsure of how I can make $$. Do I just send each property separate after I negotiate my fee or should it be 3% of the sale price. Also should I have the buyer sign a finders fee agreement? I'm thinking yes but I'm still new and figuring things out as I go.
