Congrats. I just told someone earlier that synchrony, in my opinion, gives credit limits in brackets based on scores. For example no more than $5k on a walmart card with scores 680 or below. Reason I say this is because I've read hundreds of data points to support this theory. When I told someone earlier on here they had already requested an increase to 3k and got it (Wal-Mart card). I told him to go ask for 5k and that he'd be approved. Sure enough he came back with an approval. (Btw care credit is backed by synchrony bank.) So yes I do agree that scores (TU in particular) determine CL with synchrony.
Congrats! I just got a CLI from Care Credit last month plus I opened two new Synchrony accounts in the past 2 weeks and my score took a hit due to the new accounts....I'm still tempted to ask for a CLI on my Care Credit though lol ugh choices
