So here’s the run down my dh needs a 4th revolving line but wants to apply for the cc with highest cl potential. He receives cc offers daily. He recently received WF prequal, Chase Slate, Boa and Credit One, just to name a few. He has a credit score of 703 (fico TU) due to util because he doesn’t have any baddies. He has cl of 9500 with discover, helzburg card with 3400 limit, and tjmaxx card he never uses. He also has a credid union loc with 7500 line. He is showing on cap on site prequal for qs rewards. Which card typically would have the best opportunity to get a high line?
