Wonderin,
Definitely wait until your other account updates. I know how impatient one can get in all the excitement. I've been there numerous times ! But you always want to make sure when you're applying for a new credit card or any account, that you're putting your very best foot, or score forward. If you apply now and are denied, you'll be kicking yourself and saying should have waited. and then its possible that your score updates 20-40 points higher ... and then you apply again, and are still denied.
Also those scores that you have now, are going to be denied right now by most credit card companies, unless you're looking at a secured card. And believe it or not, they still might deny you ! Even those guys have tough requirements sometimes. Also, keep in mind, you can often be declined a credit card based on specific information in your report, not just the score. Some places will deny you if you have ANY collections period. you could have a 700 score and 1 collection and be denied. A past bankruptcy regardless of age might automatically get you denied. Any accounts that are past due .. such as the one you're waiting on right now. Too many inquiries in a specific time frame could get you denied.
So its not always a score thing. Lenders have their own criteria, and some things are automatic denials, regradless of your score. So definitely let the other account update. It should definitely help the score ... and then look at the rest of your report and see if theres anything else you can work on, prior to applying for a credit card or anything else. you always want to put your best foot forward, not just for a better rate, but to be able to be qualified in the first place period ! Good luck, you've done great work so far, and stick with it. Best wishes,
Sparky =o)
