Bottom line, you need to be consistent. You shouldn't have some lenders filling out at the closing table and others not.
It has been my long standing contention that because HMDA is APPLICATION based, the information we should use is all from the time of application only. If an applicant leaves something blank (and it's not face to face) than that's how I report it, even if my mother is the borrower.

That way loans that don't close have the same collection criteria as loans that are originated.
