I'm a bit confused by your debut Fico score of 498. How many accounts were on your CR at the time that score was generated? Most of the time debut scores are around 700 or even slightly higher from what I've read. I understand you may have had maxed out utilization at the time, but I'd expect 100 points to be given up due to that, not 200+. Just an observation that something appears a bit off.
