You need to review the CIP FAQ issued by the federal agencies. Here is the link for the FDIC's FIL-4-2005 (http://www.fdic.gov/news/news/financial/2005/fil3405a.html). Here is the question and answer of interest to you:
Q: Are loan participations purchased from third parties and loans purchased from a car dealer or mortgage broker within the exclusion from the definition of “account” for loans acquired through an acquisition, merger, purchase of assets, or assumption of liabilities?
A: Yes, this exclusion is intended to cover loan participations purchased from third parties and loans purchased from a car dealer or mortgage broker. If, however, the bank is extending credit to the borrower using a car dealer or mortgage broker as its agent, then it must ensure that the dealer or broker is performing the bank’s CIP.
