I'm trying to add my older brother to my AmEx Blue for Students since he was turned down for AmEx Clear (in June). He is trying to refinance the house and so he's already taken the AmEx Clear 'hard' inquiry hit, would this be advisable for me to add him as an AU? Would it count as another inquiry for him? His EQ FICO is 557 (we didn't know AmEx required excellent credit). He has also applied and was approved for an HSBC cc (this past June), so he'll have two 'hard' hits. I recently opened my account for Blue for Students in 2/07, and have a very short credit history (11months), but my TU FICO is 682 and EQ FICO is 696. I have a 4,500 limit on my AmEx, and his new HSBC CL is 1,000, so I thought it would help him if anything, to boost his score, before the loan decision is made. What are some insights on the best approach?
