Underwriting Cheat Sheet

If you're underwriting a boat dealer, MCC 5551 concentrates risk around very large unit tickets, substantial order deposits on built-to-spec vessels, and strong seasonality. Title and registration vary by state and the Coast Guard, and post-sale condition disputes on used hulls drive chargebacks long after funding. Here's what to look for.
