Loans do not reset AoYA; other than that all great advice!
Yes they do.
But, I will admit many of the CMS front ends will list your loan as your youngest account, but the FICO algorithm does not reset your AoYA for an installment loan.
Every time I took out an SSL it reset my age of newest account, according to both Experian and MyFICO.
How can you be so certain that the FICO algorithm was not reset?
