The intent of the AAN is to tell them why they don't qualify. If it is correctable, or mis-information, they may then be able to qualify. So the root may be why don't you want to fund the loan, inadequate down payment, debt, lack of credit record, etc. The fact that you just don't want to won't be acceptable, nor is creating a reason. That will make your decisions inconsistent and add an appearance of potential discrimination if there is a patter or practice here.
The net, net, net is to define why they don't qualify.
