They are double and triple checking the work of the underwriter.
They are also doing a credit refresh prior to closing. This will tell the lender if the buyer has attempted to open up any additional credit. If they have that could affect their debt ratio and could be one of the reasons why the loan gets canceled prior to closing.
They will also do a verbal verification of employment to make sure that the buyer is still at their job and still able to pay the mortgage.
