Similar to tombstone ads in the investment banking world. Frankly, I don't know why a bank customer would agree to the public disclosure of that kind of borrowing detail. Granted, public records disclose some details of secured transactions, but I think this is way too much information.
Has the loan officer considered this downside? You would be giving your competitors hard-to-get information and essentially an invitation to launch a pinpointed assault on the relationship. I guarantee that's what my bank would do and I wouldn't fault them. Especially if the customer is a golden prospect in the community.
