We need to better understand your transaction.
You mention that the balloon was not included in the Loan Terms. Did it appear in the projected payments section on page 1? Was the balloon reflected in other disclosures, such as “In 5 years” on page 3?
Which “closing documents” included the balloon?
Did you use the same origination system to prepare the LE, CD, and the closing documents?
It is not clear whether a post closing disclosure will resolve any of the issues.
