Doing credit repair yourself means you handle every step:
Time commitment: 5-10 hours per month for 4-8 months. This includes pulling reports, analyzing them, writing dispute letters, mailing them via certified mail, tracking responses, and filing follow-up disputes.
Cost: $0 for the disputes themselves. You may spend $20-$50 on certified mail over the course of treatment. Credit reports are free at AnnualCreditReport.com.
Learning curve: Medium. You need to understand which items are disputable, how to write effective dispute letters, and what your rights are under the FCRA. The CFPB provides free templates and guides.
Success rate: Research suggests DIY disputes are about as effective as company-filed disputes for straightforward errors. The bureau doesn't care who sends the letter — they care about the legal basis of the dispute.
Where DIY struggles: Complex cases with 10+ items across multiple bureaus, creditor lawsuits, or items that require escalation to the CFPB or state attorney general. Also, many people start strong but lose motivation after month 2-3 when results aren't immediate.
