Opening several credit accounts in a short amount of time can appear risky to lenders and negatively impact your credit score. Before you take out a loan or open a new credit card account, consider the effects it could have on your credit scores. Know too, that when you're buying a car or looking around for the best mortgage rates, your inquiries may be grouped and counted as only one inquiry for the purpose of adding information to your credit report. In many commonly-used scoring models, recent inquiries have greater effect than older inquiries, and they only appear on your credit report or a maximum of 25 months.
There are a lot of reasons that your credit may be in rough shape. Most are related to your spending habits. And, if you missed a few payments or your debt levels are too high—think over 30% of your total available credit limits—disputing errors won’t help you. You’ll have to make some changes to improve your credit scores instead. And you may have to wait a bit to see an uptick.
