Again I'll say..."Income" is CONSUMER ONLY! Be sure to be clear on that
The only requirement would come into play if you decide to use the data during an exam. I addressed this in another post, but basically, any data you give to an examiner should have been through a strong data integrity test. You'll end up with egg on your face if you provide it and they find that it's crap. If she's checking it, you're in a better position than most at this point. I personally don't do data integrity on consumer lending because my small business lending is so strong I don't need the consumer "stuff". I do collect it, but don't expect to see a need for many years.
One thing to consider is...do you need it? I'd hate to be wasting time checking income on lending you probably would never submit for an exam. If you're doing it right, it takes time, and we all can normally use time elsewhere
So is it worth your while? Or should you let it go like me and worry about other deals?
