Too many “hard” checks of your credit can ding your score. For example, if you apply for several credit cards at once, several credit inquiries will appear on your report. Too many credit checks (as well as applying for/opening too many accounts) can give the impression that you’re a credit risk. Apply for new credit accounts sparingly, to limit the amount of credit checks you may incur.
You could consolidation the loans with a federal Direct Consolidation Loan. The Department of Education will issue you a new loan and use the money to pay off your existing loans. If you include your defaulted loan, that loan will be paid off, and your new consolidation loan will be current. To be eligible, you must agree to either repay the consolidation loan with an income-driven repayment plan or to make three monthly payments on your defaulted loan before applying for consolidation.
Annualcreditreport.com and the nationwide credit reporting companies will not send you an email asking for your personal information. If you get an email, see a pop-up ad, or get a phone call from someone claiming to be from annualcreditreport.com or any of the three nationwide credit reporting companies, do not reply or click on any link in the message. It’s probably a scam. Forward any such email to the FTC at firstname.lastname@example.org.
