I’ve found paying all bills on time, not having too high of a balance on any credit card (within that 30% usage that people and apps mention, meaning if you have a $1000 limit, you shouldn’t have more than $300 on it at one time).
But a lot depends upon your credit report, and if you have any issues with it. If you haven’t yet, download the app I work on (Turbo) and log in and check it out. Let us know what you think, and feel free to post specifics on your credit report.
