With all due respect but something doesn't sound right on your lenders part and the credit company they are using. I recently closed and I too had to have disputes removed from my credit report. My lender used Credit Technologies and they submitted to the agencies the request to remove the disputes and once they received notice they were removed they did a rescore and my middle score jumped up 30 points to where we needed it to be to get an automated approval and move forward to submiting to USDA. You need to crack your lenders because it dropped due to their vendor and not because of anything you did. They could have easily have gotten you to write a letter explaining the dispute instead but they opted to do it the hard way and now you're the one suffering.
