This guy doesn't know what he's doing at all. He provided a pre-approval certificate to the buyers based on guessing game. He probably never checked the real income of the buyers out but confidently provided a pre-approval certificate and we later found out that the buyers can't get a loan from any lenders based on their current income. After figuring out that the buyers can't get a loan, he didn't exist, no phone answering and avoid all e-mail communications, etc. How coward he is and unprofessional. He should go back to the hotel front desk where he used to work and he's not qualified to be a loan officer at all.
