Currently, my Credit mid score is 633. I am closing on my house on May 15th and hoping to raise my credit score to at least 640 if not higher. My current credit card utilization is at 0 and the only other debt I have is 30K in student loans that are in deferment. I do have some old late payments that are hurting my score as well. Besides time, is there anything I can do to increase my credit score? Should I keep a balance on one of my credit cards? I've read in a couple of places where that can be helpful.
All cards reporting zero except one reporting a small balance (AZEO) is supposed to be optimal formula.
If the lates are accurate then all you can really do is write goodwill letters asking creditor to remove them. Success varies and often takes a long time (repeated attempts until you get someone to say yes). Might be a long shot, but won't hurt to try. Do not dispute anything on your report, that will likely cause issues with getting your loan.
Why do you need to get your score to 640? Are you not approved with your current score?
You'll receive the all zero score penalty for reporting $0.
As mentioned up thread, implement All Zero Except One to gain points.
Ensure it's a bank card and not a store or charge card.
