What is the collateral? If it's both the home and the business, you need an appraisal on each and that appears to have been known at application, therefore no COC.
I don't see the point in needing a commercial appraisal for income verification unless it's an income-producing building (ie, renting the building out).
This situation isn't making much sense to me.
