Hi mary, welcome to the forums. There are times when you would NOT want to dispute.
Post your baddies in here and people will try to advise you what to do.
As you stated that every thing is paid. You need to know that bad accounts even late payments will stay on your CR for 7 years. Closed accounts will stay 10 years.
The length of history & CC UTIL and payments count for 65% of your scores!
GW letters are sent for paid baddies. But you want to be careful what you want deleted as it could drop you history.
If you have not done so already pull all 3 CR (FREE) get your FICO scores and then while correcting your CR I would check out the CC thread and see what CC you might be able to get. Do not just start applying!!! read what others are saying about what scores are usually needed AND always know what baddies might be on your CR.
Check out this thread it has 3 threads in it one is the abbrevs that we all use another is important because it is the frequently requested thread....this one is full of info.
Please feel free to ask as many question as you need!!!!
