Loan update

I called my mortgage broker today for an update on my pre approval status and he said that its been approved by one area BUT has been referred to credit as it is a 97% loan and that it is pretty standard procedure for these kinds of loans.... It's just frustrating because I haven't been in a position to save a heap of money but now I am... but I just don't want to wait!! He assured me it was pretty normal and to not worry... worry I still will though.
