Attention Einsteins and Hawkings: I'm just checking. Is the most accurate method of determining my AAoA to take the AAoA of each CB reporting on myFICO, reduce each to months, add them together, divide by 3 and then re-form the quotient into years and months?
AAoA-EQ + AAoA-EX + AAoA-TU = Total Sum of AAoA /3 = Overall AAoA
Overall AAoA isn't really relevant, because it's always going to be viewed with respect to the bureau that's being considered. The same way that an average credit score (for example, your 3 FICO 08 scores) divided by 3 really isn't meaningful.
Yup. CSP and Freedom. In another post, I write about the preparation for that, so I forgot to put it here, also.
From what I understand of Chase, they look often for a minimum of 1 year AoOA, not necessarily AAoA.
