I was told that I could call my older credit card banks, and
"negotiate" a payoff of the account if I close the
account. Is this true, and if so how will it impact my credit
You can always negotiate anything! Pick up the phone and call today!
Negotiating won't impact your credit rating. If you're concerned
about that then ask the bank what they are going to report. In the
incredibly remote possibility that they say they'd report something
negative just make it part of the negotiated deal the they don't
report anything. Be sure to keep good notes about who you spoke with
and what they agreed to do. Something in writing is always best.
