In many commercial brokerage transactions, it is not uncommon for the broker to present a transaction without specific details on the identity of the borrower. Basically, they are shopping on behalf of their customer, but they do not want any lender doing an "end-run" around them to get the deal.
So - they will present information on the property, LTV, cash-flow, general credit info, etc., to see if the bank is interested. In those cases, if you decide the deal is not your "cup of tea", you have no choice but to send the notice to the broker.
Yeah - and that concept is REAL popular with the commercial lenders!
