I have posted this before but still get several questions on it. You will see different dates on different reports. Most of your tri merge mortgage reports do not have the information you need to determine when something will drop off of a credit report due to the "7 year rule". You will see a DLA category on the credit report which is the date of the last activity. Do not go by this or the opened date on the account. You have to go by the ODD. (Original Date of Delinquency) This is usually always on a consumer report but never on a tri merge report. Why I have no idea but its just the way the bureaus do things. I have also notices on several credit reports in the past couple of months that the creditors or collection agencies are trying to re-report updating the ODD. This is against federal reporting guidelines and when we find it we can usually always get it off of the credit report.
I hope this helps someone and everyone have a great day.
