I just got approved last month for NFCU cash rewards with a very gracious SL > $10k (2 other cards CL < $5k).No statement yet. Now almost 5 years post bk7. How long should I wait before applying for Pen Fed? No inquiries except NFCU.
I am a firm believer to wait 4-6 months between apps. But some might say different when it comes to CU's. Which i have no experience with. Dont want to look desparate apping back to back. It may lead to a higher SL if you do wait. JMO.
As long as you're not going hogwild, you can apply now if you really want to.
Just make sure that if you're getting cards with sign up bonuses that you will have enough spend to earn them all. I got into PenFed and Navy at the same time and for reasons other than not having enough spend, ended up leaving a sign up bonus on the table :-/
I would apply now and let the inquiries age together. An app 6 months later will extend their impact (however minimal ) on your scores from 12 to 18 months .
