Will adding Experian Boost to your Experian file help your FICO 2, 4 or 5 scores? Or does it only help your FICO 8 score?
Experian Boost only applies to FICO 8 classic. It would not apply to score 2, and definitely not 4 or 5. Score 4 is a Transunion score, and 5 is an Equifax score. Also to note is that most lenders do not calculate the false inflation boost provides and will automatically strip it out of their algorithmic decision. Some mortgage lenders will even go as far as making you disable Boost before they will approve you for a mortgage. All in all, it is a service that you give a lot of access to personal information to, without receiving much of anything tangible in return.
