Hi @Lorraine Reid. In terms of which Credit Card to pay off first, I have learned that in terms of your credit, your collection of cards are looked at as an total usage rate. So you if you 3 credit cards, with 400, 700 and 1200 limits respectively, they are scored as a total of your total balance/total limit. so don't necessarily freak out over the 29%. Take care of it of course, but understand that as your overall ratio decreases, your score goes up.
Also, I just used the Experian Boost feature and it jumped my score up 15 points instantly. Basically (and I don't know if Equifax and Transunion offer this) through Experian, you link Experian to your bank account and it automatically searches your history and finds all your not reported accounts that you have linked to your bank account. So it found that I pay for my AT&T phone bill and my internet bill and gave me 15 more points just for on time payment history. The other nice feature is that anything that negatively impacts your score, it either doesn't count or you can just remove the boost feature and your score returns to normal.
I am in a near similar situation as you. In 2 months, my credit increased around 45 points just from lowering my total balance, lowering my usage rate (I actually got notifications saying "your credit score increased due to lower utilization rate", and from the Experian boost feature.
Remember this is a community of people wanting to help you as well. Network with people in your area on here! I have met a couple people on here and I am getting ready to meet with someone next week just to connect, have lunch and learn more about what they do. You may come to find that the route some people took to get to their first investment opportunity had little or nothing to do with their credit score at all.
I hope this helps a little.
