What will the lender check the day of closing?
Frequently, the lender will recheck your employment one more time on the day of closing.
Additionally, they may run a supplemental credit check to verify that you have not obtained any new credit just prior to closing.
These steps are all attempts to keep mortgage fraud to a minimum and to make sure the loan is acceptable to the purchasing entity like Fannie Mae, Freddie Mac and FHA or VA.
