How long have they had the BofA? Have they tried requesting an increase? A CLI normally doesn't hurt scores. Inqs are normally temporary or may have no affect at all. The needed CLI may out weigh anything negative. Utilization is temporary and the changes only affect the score month to month. Doubtful either will cause issues with an auto loan. I'd lay off if within 6 months of a home loan. Again, I really don't see either as an issue when landing a secured loan. The BofA account online will let them know when an increase is possible. "Increase credit limit" will be highlighted near the current limit. Always shoot for the stars. The system will counter offer if you over shoot what BofA is comfortable giving out.
