The mortgage I've had for more than eight years was sold to another company. That means my mortgage account was closed and another opened. Thus, my average account age went down and with it my Credit Karma score by 13 points.
My mortgage being sold has as much to do with my credit worthiness as Obama has to do with the murder rate in Baltimore.
The AAoA drop won't be as much with Fico. With Credit Karma you got a double whammy since they don't include closed accounts in the calculation. With Fico, where it actually matters, closed accounts are included.
