Negative Trade Lines on Bureaus- When does the 7 year clock start for them to fall off?

[teeder27]

First off, I apologize if this topic has been covered elsewhere.  I spent several hours searching and couldn't find anything so I thought I'd ask...

I am in the process of rebuilding my scores, lost a job a number of years ago and chose to keep paying my house and car, the two most important bills each month and let the credit cards slide.  Fast forward to now, everything that was charged off and negative has been paid in full and I'm back on track, sort of.  I have always been extremely credit conscious, so letting my scores crash was very hard for me to do, but life happens.  I pay for a montly credit monitoring service, www.identitysecure.com   They give me new credit reports every 30 days.  As of my new report today, I'm at 655 on experian, 664 on equifax, and 660 on trans union, so I've made progress in terms of getting the score back up, but have a long way to go to get back to where I was before.

What I'm wondering is by looking at the credit reports, how can I tell when a negative account is going to fall off of my reports?  There are several collection accounts/factoring companies, etc... on my bureaus that I can't wait to see go away.  I know about the 7 year rule, but I'm not sure when the 7 year time starts- when the account was originally opened, when it was paid off, or what? 

I have open active credit (Car lease, and several credit cards with zero balances), so I am helping my score as i go, but I'd like to know when I can expect to get some of these negative accounts to get off of my reports. 

Thanks for the assistance!

Collections fall off on the Date of First Deliquency 7-7.5 years later; that is supposed to be reported as the first time you went late (1-30 days) on the OC (original creditor) in the chain of events leading up to it's being farmed out for collection as I underestand it.

DOFD though sometimes doesn't get reported right, and by default it will be the date the collection is added to the bureaus.

As an example I have an awkward collection (not sure how I got it looking at the payment history thought I'd cancelled that account but TWC billing apparently didn't think so) which I went late on in 2009, but didn't get farmed out till late 2010.  The DOFD is 6/09 looking at it, and it's expected to come off according to the bureaus 6/16 as a result.

Different negatives have their own rules though.
